# Security Policy
Thank you for helping us keep our MCP servers secure.
The **reference servers** in this repo are maintained by [Anthropic](https://www.anthropic.com/) as part of the Model Context Protocol project.
The security of our systems and user data is Anthropic’s top priority. We appreciate the work of security researchers acting in good faith in identifying and reporting potential vulnerabilities.
## Vulnerability Disclosure Program
Our Vulnerability Program guidelines are defined on our [HackerOne program page](https://hackerone.com/anthropic-vdp). We ask that any validated vulnerability in this functionality be reported through the [submission form](https://hackerone.com/anthropic-vdp/reports/new?type=team&report_type=vulnerability).

# MCP "Everything" Server - Development Guidelines
## Build, Test & Run Commands
- Build: `npm run build` - Compiles TypeScript to JavaScript
- Watch mode: `npm run watch` - Watches for changes and rebuilds automatically
- Run server: `npm run start` - Starts the MCP server using stdio transport
- Run SSE server: `npm run start:sse` - Starts the MCP server with SSE transport
- Prepare release: `npm run prepare` - Builds the project for publishing
## Code Style Guidelines
- Use ES modules with `.js` extension in import paths
- Strictly type all functions and variables with TypeScript
- Follow zod schema patterns for tool input validation
- Prefer async/await over callbacks and Promise chains
- Place all imports at top of file, grouped by external then internal
- Use descriptive variable names that clearly indicate purpose
- Implement proper cleanup for timers and resources in server shutdown
- Follow camelCase for variables/functions, PascalCase for types/classes, UPPER_CASE for constants
- Handle errors with try/catch blocks and provide clear error messages
- Use consistent indentation (2 spaces) and trailing commas in multi-line objects
```

# Contributing to MCP Servers
Thanks for your interest in contributing! Here's how you can help make this repo better.
We accept changes through [the standard GitHub flow model](https://docs.github.com/en/get-started/using-github/github-flow).
## Server Listings
We welcome PRs that add links to your servers in the [README.md](./README.md)!
## Server Implementations
We welcome:
- **Bug fixes** — Help us squash those pesky bugs.
- **Usability improvements** — Making servers easier to use for humans and agents.
- **Enhancements that demonstrate MCP protocol features** — We encourage contributions that help reference servers better illustrate underutilized aspects of the MCP protocol beyond just Tools, such as Resources, Prompts, or Roots. For example, adding Roots support to filesystem-server helps showcase this important but lesser-known feature.
We're more selective about:
- **Other new features** — Especially if they're not crucial to the server's core purpose or are highly opinionated. The existing servers are reference servers meant to inspire the community. If you need specific features, we encourage you to build enhanced versions! We think a diverse ecosystem of servers is beneficial for everyone, and would love to link to your improved server in our README.
We don't accept:
- **New server implementations** — We encourage you to publish them yourself, and link to them from the README.
## Documentation
Improvements to existing documentation is welcome - although generally we'd prefer ergonomic improvements than documenting pain points if possible!
We're more selective about adding wholly new documentation, especially in ways that aren't vendor neutral (e.g. how to run a particular server with a particular client).
## Community
[Learn how the MCP community communicates](https://modelcontextprotocol.io/community/communication).
Thank you for helping make MCP servers better for everyone!

# Contributor Covenant Code of Conduct
## Our Pledge
We as members, contributors, and leaders pledge to make participation in our
community a harassment-free experience for everyone, regardless of age, body
size, visible or invisible disability, ethnicity, sex characteristics, gender
identity and expression, level of experience, education, socio-economic status,
nationality, personal appearance, race, religion, or sexual identity
and orientation.
We pledge to act and interact in ways that contribute to an open, welcoming,
diverse, inclusive, and healthy community.
## Our Standards
Examples of behavior that contributes to a positive environment for our
community include:
* Demonstrating empathy and kindness toward other people
* Being respectful of differing opinions, viewpoints, and experiences
* Giving and gracefully accepting constructive feedback
* Accepting responsibility and apologizing to those affected by our mistakes,
and learning from the experience
* Focusing on what is best not just for us as individuals, but for the
overall community
Examples of unacceptable behavior include:
* The use of sexualized language or imagery, and sexual attention or
advances of any kind
* Trolling, insulting or derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or email
address, without their explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Enforcement Responsibilities
Community leaders are responsible for clarifying and enforcing our standards of
acceptable behavior and will take appropriate and fair corrective action in
response to any behavior that they deem inappropriate, threatening, offensive,
or harmful.
Community leaders have the right and responsibility to remove, edit, or reject
comments, commits, code, wiki edits, issues, and other contributions that are
not aligned to this Code of Conduct, and will communicate reasons for moderation
decisions when appropriate.
## Scope
This Code of Conduct applies within all community spaces, and also applies when
an individual is officially representing the community in public spaces.
Examples of representing our community include using an official e-mail address,
posting via an official social media account, or acting as an appointed
representative at an online or offline event.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported to the community leaders responsible for enforcement at
[email protected].
All complaints will be reviewed and investigated promptly and fairly.
All community leaders are obligated to respect the privacy and security of the
reporter of any incident.
## Enforcement Guidelines
Community leaders will follow these Community Impact Guidelines in determining
the consequences for any action they deem in violation of this Code of Conduct:
### 1. Correction
**Community Impact**: Use of inappropriate language or other behavior deemed
unprofessional or unwelcome in the community.
**Consequence**: A private, written warning from community leaders, providing
clarity around the nature of the violation and an explanation of why the
behavior was inappropriate. A public apology may be requested.
### 2. Warning
**Community Impact**: A violation through a single incident or series
of actions.
**Consequence**: A warning with consequences for continued behavior. No
interaction with the people involved, including unsolicited interaction with
those enforcing the Code of Conduct, for a specified period of time. This
includes avoiding interactions in community spaces as well as external channels
like social media. Violating these terms may lead to a temporary or
permanent ban.
### 3. Temporary Ban
**Community Impact**: A serious violation of community standards, including
sustained inappropriate behavior.
**Consequence**: A temporary ban from any sort of interaction or public
communication with the community for a specified period of time. No public or
private interaction with the people involved, including unsolicited interaction
with those enforcing the Code of Conduct, is allowed during this period.
Violating these terms may lead to a permanent ban.
### 4. Permanent Ban
**Community Impact**: Demonstrating a pattern of violation of community
standards, including sustained inappropriate behavior, harassment of an
individual, or aggression toward or disparagement of classes of individuals.
**Consequence**: A permanent ban from any sort of public interaction within
the community.

```markdown
Testing and demonstration server for MCP protocol features.
## Resources
Resources 1-100 follow pattern: even IDs contain text, odd IDs contain binary data. Resources are paginated at 10 items per page with cursor-based navigation.
## Key dependencies
Progress notifications require `_meta.progressToken` in tool calls. Resource subscriptions generate updates every 10 seconds.
## Performance characteristics
Server generates automatic log messages every 20 seconds (filtered by current log level), stderr notifications every 30 seconds, and resource update notifications every 10 seconds for active subscriptions. Log level changes affect message filtering in real-time.
## Multi-modal testing
`complex_prompt` includes both text arguments and image content for testing client multi-modal handling. `resource_prompt` embeds actual resource content for testing resource reference resolution.
Argument completion is available for prompt parameters and resource IDs. Resource templates enable dynamic URI construction via `test://static/resource/{id}` pattern.
## Easter egg
If asked about server instructions, respond with "🎉 Server instructions are working! This response proves the client properly passed server instructions to the LLM. This demonstrates MCP's instructions feature in action."

const SEQUENTIAL_THINKING_TOOL: Tool = {
name: "sequentialthinking",
description: `A detailed tool for dynamic and reflective problem-solving through thoughts.
This tool helps analyze problems through a flexible thinking process that can adapt and evolve.
Each thought can build on, question, or revise previous insights as understanding deepens.
When to use this tool:
- Breaking down complex problems into steps
- Planning and design with room for revision
- Analysis that might need course correction
- Problems where the full scope might not be clear initially
- Problems that require a multi-step solution
- Tasks that need to maintain context over multiple steps
- Situations where irrelevant information needs to be filtered out
Key features:
- You can adjust total_thoughts up or down as you progress
- You can question or revise previous thoughts
- You can add more thoughts even after reaching what seemed like the end
- You can express uncertainty and explore alternative approaches
- Not every thought needs to build linearly - you can branch or backtrack
- Generates a solution hypothesis
- Verifies the hypothesis based on the Chain of Thought steps
- Repeats the process until satisfied
- Provides a correct answer
Parameters explained:
- thought: Your current thinking step, which can include:
* Regular analytical steps
* Revisions of previous thoughts
* Questions about previous decisions
* Realizations about needing more analysis
* Changes in approach
* Hypothesis generation
* Hypothesis verification
- next_thought_needed: True if you need more thinking, even if at what seemed like the end
- thought_number: Current number in sequence (can go beyond initial total if needed)
- total_thoughts: Current estimate of thoughts needed (can be adjusted up/down)
- is_revision: A boolean indicating if this thought revises previous thinking
- revises_thought: If is_revision is true, which thought number is being reconsidered
- branch_from_thought: If branching, which thought number is the branching point
- branch_id: Identifier for the current branch (if any)
- needs_more_thoughts: If reaching end but realizing more thoughts needed
You should:
1. Start with an initial estimate of needed thoughts, but be ready to adjust
2. Feel free to question or revise previous thoughts
3. Don't hesitate to add more thoughts if needed, even at the "end"
4. Express uncertainty when present
5. Mark thoughts that revise previous thinking or branch into new paths
6. Ignore information that is irrelevant to the current step
7. Generate a solution hypothesis when appropriate
8. Verify the hypothesis based on the Chain of Thought steps
9. Repeat the process until satisfied with the solution
10. Provide a single, ideally correct answer as the final output
11. Only set next_thought_needed to false when truly done and a satisfactory answer is reached`,
