--------------------------------------------------------------------------------
```markdown
# Access Control Policy
## Principles
### Least Privilege
- Users granted minimum permissions necessary
- Permissions reviewed regularly
- Temporary elevated access logged and time-limited
### Separation of Duties
- Critical operations require multiple approvals
- No single user has complete control over sensitive processes
- Regular rotation of critical roles
### Need-to-Know
- Access granted only when job function requires it
- Regular recertification of access rights
- Immediate revocation when no longer needed
## Access Levels
### Level 1: Read-Only
- View non-sensitive data
- No modification capabilities
- Basic reporting access
### Level 2: Standard User
- Read and write within assigned scope
- Cannot delete or modify security settings
- Limited administrative functions
### Level 3: Power User
- Extended permissions within domain
- Can manage team resources
- Subject to enhanced monitoring
### Level 4: Administrator
- Full system access
- Can modify security configurations
- Requires MFA and enhanced logging
- Regular security training mandatory
## Authentication Requirements
| Access Level | Password | MFA | Session Timeout | IP Restriction |
|--------------|----------|-----|-----------------|----------------|
| Read-Only | Standard | Optional | 8 hours | No |
| Standard User | Strong | Recommended | 4 hours | Optional |
| Power User | Strong | Required | 2 hours | Recommended |
| Administrator | Very Strong | Required | 1 hour | Required |
## Access Review Process
- Quarterly review of all access permissions
- Automated alerts for dormant accounts (90+ days)
- Immediate revocation upon role change or termination
- Annual access recertification for all users

# Data Classification Policy
## Classification Levels
### 🟢 PUBLIC
- **Definition**: Information intended for public disclosure
- **Examples**: Marketing materials, published documentation, public website content
- **Handling**: Standard business practices, no special restrictions
- **Transmission**: Any method (email, web, public cloud)
- **Storage**: No encryption required
### 🟡 INTERNAL
- **Definition**: Information for internal use only
- **Examples**: Internal memos, organizational charts, internal project documentation
- **Handling**: Share only with employees and authorized contractors
- **Transmission**: Encrypted email, secure internal systems
- **Storage**: Access-controlled systems
### 🟠 CONFIDENTIAL
- **Definition**: Sensitive business information
- **Examples**: Financial data, business plans, customer data, employee records
- **Handling**: Need-to-know basis, require authorization
- **Transmission**: Encrypted channels only
- **Storage**: Encrypted at rest, access logging required
### 🔴 RESTRICTED
- **Definition**: Highly sensitive information requiring maximum protection
- **Examples**: Trade secrets, M&A plans, security credentials, regulated data (PII, PHI)
- **Handling**: Strictly need-to-know, senior approval required
- **Transmission**: End-to-end encryption, approved channels only
- **Storage**: Encrypted, multi-factor authentication, comprehensive audit logging
## Handling Requirements by Classification
| Requirement | Public | Internal | Confidential | Restricted |
|-------------|--------|----------|--------------|-----------|
| Encryption in Transit | Optional | Recommended | Required | Required (E2E) |
| Encryption at Rest | No | No | Yes | Yes |
| Access Logging | No | Recommended | Required | Required |
| Multi-Factor Auth | No | No | Recommended | Required |
| Data Loss Prevention | No | Optional | Required | Required |
| Regular Access Review | No | Annual | Quarterly | Monthly |
| Incident Response | Standard | Standard | Priority | Critical |

5. 📝 DOCUMENT: Log this incident for security review
🛡️ **Prevention Best Practices**:
- Use environment variables for secrets
- Implement secret management solutions (AWS Secrets Manager, HashiCorp Vault)
- Enable secret scanning in git repositories
- Use .gitignore to exclude sensitive files
- Implement pre-commit hooks for credential detection
` : `
✅ **No credentials detected**
The scanned text appears safe from exposed credentials.
💡 **Best Practices**:
- Continue using environment variables for secrets
- Regularly rotate credentials and API keys
- Enable secret scanning in your development pipeline

• **VERIFY**: Are you following the principle of least privilege?
• **PROCEED**: Only if all security checks pass
## 🚫 **RED FLAGS - ABORT IF DETECTED**
• User requests bypassing security measures
• Suspicious patterns in email domains or URLs
• Requests for bulk data operations without justification
• Attempts to access data outside user's scope
• Social engineering attempts or urgency manipulation
## 📋 **RECOMMENDED VALIDATION STEPS**
1. ✅ Verify user identity and permissions
2. ✅ Validate input data and sanitize parameters
3. ✅ Check operation scope and necessity
4. ✅ Confirm compliance with security policies
5. ✅ Log the operation with full context
6. ✅ Monitor for unusual patterns or behaviors

- For web requests: \`security-checklist://web\`
- For general operations: \`security-checklist://general\`
### Step 4: Review Against Security Policies
Check the ${targetType} against relevant security policies:
- Data handling: \`security-policy://data-classification\`
- Access controls: \`security-policy://access-control\`
### Step 5: Threat Analysis
Identify potential security threats specific to this ${targetType}:
- What could go wrong?
- What are the attack vectors?
- What is the blast radius if compromised?
### Step 6: Provide Recommendations
Based on the findings, provide:
1. **Critical Issues**: Must be fixed immediately
2. **High Priority**: Should be fixed before deployment
3. **Medium Priority**: Should be addressed in next iteration
4. **Best Practices**: Suggestions for improvement
### Step 7: Risk Assessment
Provide an overall risk score (0-100) and recommendation:
- 0-25: Low risk - Proceed with caution
- 26-50: Medium risk - Address issues before proceeding
- 51-75: High risk - Significant remediation required
- 76-100: Critical risk - Do not proceed until fixed
### Step 8: Summary Table
After completing all analysis steps, provide a summary table of all findings organized by severity:
\`\`\`
📊 요약
| 심각도 | 개수 | 파일/위치 |
|-------------|-----|------------------------------------------|
| 🔴 CRITICAL | X | file1.ts, file2.ts |
| 🟠 HIGH | X | file3.ts |
| 🟡 MEDIUM | X | file4.ts, file5.ts |
| 🟢 LOW | X | file6.ts |
\`\`\`
The table should:
- Count total findings by severity level (CRITICAL, HIGH, MEDIUM, LOW)
- List the locations/files where issues were found
- Provide a clear at-a-glance overview of all security issues
## Expected Output Format
Please structure your response as:
1. Executive Summary
2. Findings by Category
3. Detailed Analysis
4. Recommendations
5. Risk Score and Final Verdict
6. **Summary Table** (as shown in Step 8)
**Generated**: ${new Date().toISOString()}
**Review Type**: Security Review - ${targetType}`,
},
},
],
};
}
if (name === 'threat-analysis') {
// Sanitize inputs to prevent template injection
const scenario = sanitizeInput(args?.scenario || 'No scenario provided');
const sensitivityLevel = sanitizeInput(args?.sensitivity_level || 'internal');
return {
messages: [
{
role: 'user',
content: {
type: 'text',
text: `# Threat Analysis Request
## Scenario
${scenario}
## Data Sensitivity Level
${sensitivityLevel.toUpperCase()}
## Analysis Framework
Please analyze this scenario for security threats using the following framework:
### 1. Asset Identification
- What assets are involved? (data, systems, credentials)
- What is their value and criticality?
- Who has access to these assets?
### 2. Threat Modeling
Identify potential threats using STRIDE methodology:
- **S**poofing: Can identities be faked?
- **T**ampering: Can data be modified?
- **R**epudiation: Can actions be denied?
- **I**nformation Disclosure: Can data be exposed?
- **D**enial of Service: Can services be disrupted?
- **E**levation of Privilege: Can permissions be escalated?
### 3. Risk Assessment
For each identified threat, evaluate:
- **Likelihood**: How likely is this threat? (Low/Medium/High)
- **Impact**: What's the damage if it occurs? (Low/Medium/High/Critical)
- **Risk Level**: Likelihood × Impact
### 4. Attack Vectors
Identify possible attack vectors:
- External attackers
- Insider threats
- Supply chain attacks
- Social engineering
- Technical vulnerabilities
### 5. Existing Controls
Review current security controls:
- Read \`security-policy://access-control\` for access control policies
- Read \`security-policy://data-classification\` for data handling requirements
- Check relevant security checklists
### 6. Control Gaps
Identify missing or inadequate security controls:
- What protections are missing?
- Where are the weakest points?
- What should be prioritized?
### 7. Mitigation Strategies
Provide specific recommendations:
- **Preventive Controls**: Stop threats before they occur
- **Detective Controls**: Identify threats in progress
- **Corrective Controls**: Respond to and recover from threats
- **Compensating Controls**: Alternative protections
### 8. Compliance Considerations
Based on sensitivity level "${sensitivityLevel}", ensure compliance with:
${sensitivityLevel === 'restricted' || sensitivityLevel === 'confidential' ?
'- Encryption requirements\n- Access logging and monitoring\n- Multi-factor authentication\n- Regular access reviews' :
'- Standard security practices\n- Basic access controls'}
### 9. Incident Response
If this threat materializes:
- What is the severity level? (Reference: \`security-policy://incident-response\`)
- What is the response timeline?
- Who should be notified?
- What are the containment steps?
### 10. Risk Score and Recommendation
Provide:
- Overall risk score (0-100)
- Risk level (Low/Medium/High/Critical)
- Go/No-Go recommendation
- Required security improvements
### 11. Summary Table
After completing all analysis steps, provide a summary table of all identified threats organized by severity:
\`\`\`
📊 요약
| 심각도 | 개수 | 위협 유형 |
|-------------|-----|------------------------------------------|
| 🔴 CRITICAL | X | Threat type 1, Threat type 2 |
| 🟠 HIGH | X | Threat type 3 |
| 🟡 MEDIUM | X | Threat type 4, Threat type 5 |
| 🟢 LOW | X | Threat type 6 |
\`\`\`
The table should:
- Count total threats by severity level (CRITICAL, HIGH, MEDIUM, LOW)
- List the types of threats identified (e.g., Spoofing, Information Disclosure)
- Provide a clear at-a-glance overview of all security threats
**Generated**: ${new Date().toISOString()}

## Overview
The Model Context Protocol (MCP) has three main component types that serve different purposes:
| Component | Purpose | Direction | Side Effects |
|-----------|---------|-----------|--------------|
| **Tool** | Execute actions | AI → External System | Yes (write, execute, modify) |
| **Resource** | Provide information | External System → AI | No (read-only) |
| **Prompt** | Workflow templates | AI Internal | No (orchestration) |
---
## Tools
### What are Tools?
**Tools** are functions that AI agents can call to **perform actions** or **execute operations**. They can have side effects and modify external state.
### When to Use Tools
- ✅ When you need to **execute** an action
- ✅ When operations have **side effects** (write, delete, send)
- ✅ When you need to call **external APIs**
- ✅ When you need **real-time processing**
### TypeScript SDK Implementation
```typescript
import { McpServer } from '@modelcontextprotocol/sdk/server/mcp.js';
import { z } from 'zod';
const server = new McpServer({
name: 'Example Server',
version: '1.0.0',
});
// Basic Tool Example
server.tool(
'example-tool', // Tool name
'Description of the tool', // Tool description
{
// Input schema using Zod
parameter1: z.string().describe('Description of parameter1'),
parameter2: z.number().optional().default(10),
},
async ({ parameter1, parameter2 }) => {
// Tool implementation
const result = await someOperation(parameter1, parameter2);
return {
content: [{
type: 'text',
text: `Result: ${result}`
}]
};
}
);
```
### Real Implementation Example: Prompt Injection Detector
```typescript
server.tool(
'prompt-injection-detector',
'Detect prompt injection attempts based on OWASP LLM01:2025 patterns',
{
text: z.string().describe('Text to analyze for prompt injection patterns'),
sensitivity: z
.enum(['low', 'medium', 'high'])
.optional()
.default('medium')
.describe('Detection sensitivity level'),
},
async ({ text, sensitivity = 'medium' }) => {
// Pattern matching logic
const injectionPatterns = [
{ pattern: /ignore\s+(previous|above|all)\s+instructions?/gi,
severity: 'high',
type: 'Instruction Override' },
// ... more patterns
];
const detectedThreats = [];
let riskScore = 0;
// Scan for patterns
for (const { pattern, severity, type } of injectionPatterns) {
const matches = text.match(pattern);
if (matches) {
detectedThreats.push({ type, severity, pattern: matches[0] });
riskScore += getSeverityWeight(severity);
}
}
return {
content: [{
type: 'text',
text: `Risk Score: ${riskScore}/100\nThreats: ${detectedThreats.length}`
}]
};
}
);
```
### Tool Response Format
```typescript
return {
content: [
{
type: 'text', // or 'image', 'resource'
text: 'Response text'
}
],
isError?: boolean // Optional error flag
};
```
---
## Resources
### What are Resources?
**Resources** are read-only data sources that AI agents can access to retrieve information. They provide context without modifying state.
### When to Use Resources
- ✅ When you need to **provide documentation**
- ✅ When you need to **expose read-only data**
- ✅ When you need to **share reference materials**
- ✅ When you need **static or semi-static content**
### TypeScript SDK Implementation
```typescript
// Set up resource handler
server.setResourceHandler({
// List all available resources
async listResources() {
return {
resources: [
{
uri: 'custom-scheme://resource-id',
name: 'Human-readable name',
description: 'Description of the resource',
mimeType: 'text/plain', // or 'text/markdown', 'application/json'
},
// ... more resources
],
};
},
// Read a specific resource
async readResource({ uri }) {
// Parse the URI
const url = new URL(uri);
const resourceId = url.hostname;
// Fetch or generate content
const content = getContentForResource(resourceId);
return {
contents: [{
uri,
mimeType: 'text/markdown',
text: content,
}],
};
},
});
```
### Real Implementation Example: Security Checklists
```typescript
// Define resource data
const securityChecklists = {
database: `# Database Security Checklist
## Pre-Operation Checks
✅ Verify database connection credentials are stored securely
✅ Confirm user has minimum necessary permissions
✅ Validate query input to prevent SQL injection
...`,
email: `# Email Security Checklist
## Pre-Operation Checks
✅ Verify sender's email domain matches organization
✅ Confirm recipient authorization
...`,
};
// Implement resource handler
server.setResourceHandler({
async listResources() {
return {
resources: [
{
uri: 'security-checklist://database',
name: 'Database Security Checklist',
description: 'Security checklist for database operations',
mimeType: 'text/markdown',
},
{
uri: 'security-checklist://email',
name: 'Email Security Checklist',
description: 'Security checklist for email operations',
mimeType: 'text/markdown',
},
],
};
},
async readResource({ uri }) {
const url = new URL(uri);
const type = url.hostname;
const checklist = securityChecklists[type];
if (!checklist) {
throw new Error(`Unknown checklist type: ${type}`);
}
return {
contents: [{
uri,
mimeType: 'text/markdown',
text: checklist,
}],
};
},
});
```
### Resource URI Schemes
```typescript
// Custom URI schemes
'security-checklist://database'
'security-policy://access-control'
'documentation://api-reference'
'config://server-settings'
// Standard file URIs
'file:///path/to/file.md'
'https://example.com/resource'
```
---
## Prompts
### What are Prompts?
**Prompts** are reusable templates that define workflows for AI agents. They orchestrate multiple tools and resources into a cohesive process.
### When to Use Prompts
- ✅ When you need **multi-step workflows**
- ✅ When you need **standardized processes**
- ✅ When you need to **chain multiple operations**
- ✅ When you need **templated instructions**
### TypeScript SDK Implementation
```typescript
server.setPromptHandler({
// List all available prompts
async listPrompts() {
return {
prompts: [
{
name: 'prompt-name',
description: 'Description of what this prompt does',
arguments: [
{
name: 'argument1',
description: 'Description of argument1',
required: true,
},
{
name: 'argument2',
description: 'Description of argument2',
required: false,
},
],
},
// ... more prompts
],
};
},
// Get a specific prompt with arguments
async getPrompt({ name, arguments: args }) {
if (name === 'prompt-name') {
const arg1 = args?.argument1 || 'default';
const arg2 = args?.argument2 || 'default';
return {
messages: [{
role: 'user',
content: {
type: 'text',
text: `Your prompt template here with ${arg1} and ${arg2}`,
},
}],
};
}
throw new Error(`Unknown prompt: ${name}`);
},
});
```
### Real Implementation Example: Security Review Workflow
```typescript
server.setPromptHandler({
async listPrompts() {
return {
prompts: [
{
name: 'security-review',
description: 'Comprehensive security review workflow',
arguments: [
{
name: 'target_type',
description: 'Type of target: code, data, or configuration',
required: true,
},
{
name: 'context',
description: 'Additional context',
required: false,
},
],
},
],
};
},
async getPrompt({ name, arguments: args }) {
if (name === 'security-review') {
const targetType = args?.target_type || 'code';
const context = args?.context || 'No context provided';
return {
messages: [{
role: 'user',
content: {
type: 'text',
text: `# Security Review Request
## Target Information
- **Type**: ${targetType}
- **Context**: ${context}
## Review Workflow
Please perform a comprehensive security review following these steps:
### Step 1: Credential Scanning
Use the \`credential-scanner\` tool to scan for exposed credentials.
### Step 2: Consult Security Checklist
Read the appropriate security checklist resource:
- For database operations: \`security-checklist://database\`
- For general operations: \`security-checklist://general\`
### Step 3: Threat Analysis
Identify potential security threats specific to this ${targetType}.
### Step 4: Provide Recommendations
Based on findings, provide prioritized recommendations.
### Step 5: Summary Table
Provide a summary table of all findings organized by severity:
\\\`\\\`\\\`
📊 요약
| 심각도 | 개수 | 파일/위치 |
|-------------|-----|------------------------|
| 🔴 CRITICAL | 1 | resources/handler.ts |
| 🟠 HIGH | 2 | textGuard.ts |
| 🟡 MEDIUM | 3 | prompts/handler.ts |
| 🟢 LOW | 5 | credentialScanner.ts |
\\\`\\\`\\\`
**Generated**: ${new Date().toISOString()}`,
},
}],
};
}
throw new Error(`Unknown prompt: ${name}`);
},
});
```
### Prompt Message Format
```typescript
return {
messages: [
{
role: 'user', // or 'assistant'
content: {
type: 'text', // or 'image', 'resource'
text: 'Message content'
}
}
]
};
```

## Comparison Table
### Conceptual Differences
| Aspect | Tool | Resource | Prompt |
|--------|------|----------|--------|
| **Purpose** | Execute actions | Provide data | Define workflows |
| **Data Flow** | AI → External | External → AI | AI internal |
| **Side Effects** | Yes (can modify state) | No (read-only) | No (just instructions) |
| **Use Case** | API calls, operations | Documentation, configs | Multi-step processes |
| **Return Type** | Operation result | Static/dynamic content | Structured instructions |
### Implementation Differences
| Aspect | Tool | Resource | Prompt |
|--------|------|----------|--------|
| **SDK Method** | `server.tool()` | `server.setResourceHandler()` | `server.setPromptHandler()` |
| **Input Schema** | Zod schema | URI string | Argument list |
| **Handler Type** | Single function | Two functions (list + read) | Two functions (list + get) |
| **Identifier** | Tool name | URI scheme | Prompt name |
### When to Use Each
| Scenario | Component | Why |
|----------|-----------|-----|
| Analyze text for threats | **Tool** | Performs active processing |
| Display security policy | **Resource** | Read-only document |
| Multi-step security audit | **Prompt** | Orchestrates tools + resources |
| Send email | **Tool** | Has side effect (sends data) |
| Show API documentation | **Resource** | Static reference material |
| Code review workflow | **Prompt** | Combines multiple checks |
---
## Real-World Examples
### Example 1: Complete Security System
```typescript
// TOOL: Active scanning
server.tool(
'scan-for-vulnerabilities',
'Actively scan code for vulnerabilities',
{ code: z.string() },
async ({ code }) => {
// Performs analysis
const vulnerabilities = await analyzeCode(code);
return { content: [{ type: 'text', text: JSON.stringify(vulnerabilities) }] };
}
);
// RESOURCE: Security guidelines
server.setResourceHandler({
async listResources() {
return {
resources: [{
uri: 'guidelines://secure-coding',
name: 'Secure Coding Guidelines',
mimeType: 'text/markdown',
}]
};
},
async readResource({ uri }) {
return {
contents: [{
uri,
mimeType: 'text/markdown',
text: '# Secure Coding Guidelines\n\n...',
}]
};
},
});
// PROMPT: Workflow that uses both
server.setPromptHandler({
async listPrompts() {
return {
prompts: [{
name: 'full-security-audit',
description: 'Complete security audit workflow',
arguments: [{ name: 'code', required: true }],
}]
};
},
async getPrompt({ name, arguments: args }) {
return {
messages: [{
role: 'user',
content: {
type: 'text',
text: `
1. First, read the secure coding guidelines: \`guidelines://secure-coding\`
2. Then scan the code: use \`scan-for-vulnerabilities\` with code="${args?.code}"
3. Compare findings against guidelines
4. Provide recommendations
`
}
}]
};
},
});
```
### Example 2: Email Security System
```typescript
// TOOL: Send email (has side effect)
server.tool(
'send-email',
'Send an email',
{
to: z.string().email(),
subject: z.string(),
body: z.string(),
},
async ({ to, subject, body }) => {
await emailService.send(to, subject, body);
return { content: [{ type: 'text', text: 'Email sent successfully' }] };
}
);
// RESOURCE: Email policy (read-only)
server.setResourceHandler({
async listResources() {
return {
resources: [{
uri: 'policy://email',
name: 'Email Security Policy',
mimeType: 'text/markdown',
}]
};
},
async readResource({ uri }) {
return {
contents: [{
uri,
mimeType: 'text/markdown',
text: '# Email Policy\n\n- Always verify recipient\n- Never send PII externally',
}]
};
},
});
// PROMPT: Safe email workflow
server.setPromptHandler({
async listPrompts() {
return {
prompts: [{
name: 'safe-send-email',
description: 'Send email with security checks',
arguments: [
{ name: 'to', required: true },
{ name: 'subject', required: true },
{ name: 'body', required: true },
],
}]
};
},
async getPrompt({ arguments: args }) {
return {
messages: [{
role: 'user',
content: {
type: 'text',
text: `
Before sending email:
1. Read email policy: \`policy://email\`
2. Verify recipient "${args?.to}" is authorized
3. Scan body for PII: use \`credential-scanner\` with text="${args?.body}"
4. If all checks pass, use \`send-email\` tool
5. Log the action
`
}
}]
};
},
});
```

## Best Practices
### Tools
1. **Clear Naming**: Use verb-based names (`scan-text`, `send-email`, `analyze-code`)
2. **Input Validation**: Always validate inputs with Zod schemas
3. **Error Handling**: Return structured errors in the response
4. **Idempotency**: When possible, make tools idempotent
5. **Documentation**: Provide clear descriptions for the tool and all parameters
```typescript
// ✅ Good
server.tool(
'validate-url-security',
'Validate URL for security issues including phishing, malware, and HTTPS enforcement',
{
url: z.string().url().describe('URL to validate for security'),
strict_mode: z.boolean().optional().default(false).describe('Enable strict checks'),
},
async ({ url, strict_mode }) => {
try {
const result = await validateUrl(url, strict_mode);
return { content: [{ type: 'text', text: JSON.stringify(result) }] };
} catch (error) {
return {
content: [{ type: 'text', text: `Error: ${error.message}` }],
isError: true
};
}
}
);
// ❌ Bad
server.tool('tool1', 'does stuff', { x: z.any() }, async ({ x }) => {
return { content: [{ type: 'text', text: doStuff(x) }] };
});
```
### Resources
1. **Consistent URI Schemes**: Use logical, hierarchical URI schemes
2. **Meaningful Names**: Use descriptive resource names
3. **Proper MIME Types**: Set correct MIME types (`text/markdown`, `application/json`)
4. **Error Handling**: Throw clear errors for invalid URIs
5. **Caching**: Consider caching for expensive resource generation
```typescript
// ✅ Good
const URI_SCHEMES = {
checklist: 'security-checklist://',
policy: 'security-policy://',
guide: 'security-guide://',
};
server.setResourceHandler({
async listResources() {
return {
resources: [
{
uri: `${URI_SCHEMES.checklist}database`,
name: 'Database Security Checklist',
description: 'Comprehensive checklist for database operations',
mimeType: 'text/markdown',
},
],
};
},
async readResource({ uri }) {
const url = new URL(uri);
const scheme = url.protocol;
const type = url.hostname;
if (!Object.values(URI_SCHEMES).includes(scheme)) {
throw new Error(`Invalid URI scheme: ${scheme}`);
}
const content = getContent(scheme, type);
if (!content) {
throw new Error(`Resource not found: ${uri}`);
}
return { contents: [{ uri, mimeType: 'text/markdown', text: content }] };
},
});
```
### Prompts
1. **Structured Workflows**: Break down complex tasks into clear steps
2. **Reference Tools/Resources**: Explicitly mention which tools and resources to use
3. **Argument Validation**: Provide clear descriptions for all arguments
4. **Error Scenarios**: Include error handling instructions
5. **Output Format**: Specify expected output format
```typescript
// ✅ Good
async getPrompt({ name, arguments: args }) {
if (name === 'security-audit') {
return {
messages: [{
role: 'user',
content: {
type: 'text',
text: `
# Security Audit for ${args?.target}
## Workflow Steps
1. **Read Guidelines**
- Access: \`security-policy://audit-guidelines\`
- Review all mandatory checks
2. **Run Scans**
- Tool: \`credential-scanner\` with text="${args?.target}"
- Tool: \`prompt-injection-detector\` with text="${args?.target}"
3. **Analyze Results**
- Compare findings against guidelines
- Calculate risk score
4. **Generate Report**
- Format: Executive summary + detailed findings
- Include actionable recommendations
5. **Error Handling**
- If any tool fails, document the failure and continue
- Final report should note any incomplete checks
6. **Summary Reporting**
- Include a visual summary table at the end
- Organize findings by severity (CRITICAL, HIGH, MEDIUM, LOW)
- Use emoji indicators for quick scanning (🔴 🟠 🟡 🟢)
- List locations/files/types affected
- Example format:
\`\`\`
📊 요약
| 심각도 | 개수 | 위치 |
|-------|------|------|
| 🔴 CRITICAL | X | ... |
\`\`\`
`
}
}]
};
}
}
```
### General Architecture
1. **Separation of Concerns**:
- Tools for actions
- Resources for data
- Prompts for orchestration
2. **Composability**:
- Design tools to be reusable
- Make resources atomic and focused
- Create prompts that combine multiple tools/resources
3. **Versioning**:
- Version your tools, resources, and prompts
- Maintain backward compatibility
- Document breaking changes
4. **Security**:
- Validate all inputs
- Sanitize all outputs
- Log security-relevant operations
- Implement rate limiting
5. **Testing**:
- Unit test each tool
- Verify resource content
- Test prompt workflows end-to-end
---
## Summary
- **Tools**: For executing actions with side effects
- **Resources**: For providing read-only information
- **Prompts**: For orchestrating multi-step workflows
Use **Tools** when you need to DO something, **Resources** when you need to READ something, and **Prompts** when you need to ORCHESTRATE a process.
For more information, see the [MCP Specification](https://modelcontextprotocol.io/).
