1 | # MCPGO Package
2 |
3 | The `mcpgo` package provides an abstraction layer over the `github.com/mark3labs/mcp-go` library. Its purpose is to isolate this external dependency from the rest of the application by wrapping all necessary functionality within clean interfaces.
4 |
5 | ## Purpose
6 |
7 | This package was created to isolate the `mark3labs/mcp-go` dependency for several key reasons:
8 |
9 | 1. **Dependency Isolation**: Confine all `mark3labs/mcp-go` imports to this package, ensuring the rest of the application does not directly depend on this external library.
10 |
11 | 2. **Official MCP GO SDK and Future Compatibility**: Prepare for the eventual release of an official MCP SDK by creating a clean abstraction layer that can be updated to use the official SDK when it becomes available. The official SDK is currently under development (see [Official MCP Go SDK discussion](https://github.com/orgs/modelcontextprotocol/discussions/224#discussioncomment-12927030)).
12 |
13 | 3. **Simplified API**: Provide a more focused, application-specific API that only exposes the functionality needed by our application.
14 |
15 | 4. **Error Handling**: Implement proper error handling patterns rather than relying on panics, making the application more robust.
16 |
17 | ## Components
18 |
19 | The package contains several core components:
20 |
21 | - **Server**: An interface representing an MCP server, with the `mark3labsImpl` providing the current implementation.
22 | - **Tool**: Interface for defining MCP tools that can be registered with the server.
23 | - **TransportServer**: Interface for different transport mechanisms (stdio, TCP).
24 | - **ToolResult/ToolParameter**: Structures for handling tool calls and results.
25 |
26 | ## Parameter Helper Functions
27 |
28 | The package provides convenience functions for creating tool parameters:
29 |
30 | - `WithString(name, description string, required bool)`: Creates a string parameter
31 | - `WithNumber(name, description string, required bool)`: Creates a number parameter
32 | - `WithBoolean(name, description string, required bool)`: Creates a boolean parameter
33 | - `WithObject(name, description string, required bool)`: Creates an object parameter
34 | - `WithArray(name, description string, required bool)`: Creates an array parameter
35 |
36 | ## Tool Result Helper Functions
37 |
38 | The package also provides functions for creating tool results:
39 |
40 | - `NewToolResultText(text string)`: Creates a text result
41 | - `NewToolResultJSON(data interface{})`: Creates a JSON result
42 | - `NewToolResultError(text string)`: Creates an error result
43 |
44 | ## Usage Example
45 |
46 | ```go
47 | // Create a server
48 | server := mcpgo.NewServer(
49 | "my-server",
50 | "1.0.0",
51 | mcpgo.WithLogging(),
52 | mcpgo.WithToolCapabilities(true),
53 | )
54 |
55 | // Create a tool
56 | tool := mcpgo.NewTool(
57 | "my_tool",
58 | "Description of my tool",
59 | []mcpgo.ToolParameter{
60 | mcpgo.WithString(
61 | "param1",
62 | mcpgo.Description("Description of param1"),
63 | mcpgo.Required(),
64 | ),
65 | },
66 | func(ctx context.Context, req mcpgo.CallToolRequest) (*mcpgo.ToolResult, error) {
67 | // Extract parameter value
68 | param1Value, ok := req.Arguments["param1"]
69 | if !ok {
70 | return mcpgo.NewToolResultError("Missing required parameter: param1"), nil
71 | }
72 |
73 | // Process and return result
74 | return mcpgo.NewToolResultText("Result: " + param1Value.(string)), nil
75 | },
76 | )
77 |
78 | // Add tool to server
79 | server.AddTools(tool)
80 |
81 | // Create and run a stdio server
82 | stdioServer, err := mcpgo.NewStdioServer(server)
83 | if err != nil {
84 | log.Fatalf("Failed to create stdio server: %v", err)
85 | }
86 | err = stdioServer.Listen(context.Background(), os.Stdin, os.Stdout)
87 | if err != nil {
88 | log.Fatalf("Server error: %v", err)
89 | }
90 | ```
91 |
92 | ## Real-world Example
93 |
94 | Here's how we use this package in the Razorpay MCP server to create a payment fetching tool:
95 |
96 | ```go
97 | // FetchPayment returns a tool that fetches payment details using payment_id
98 | func FetchPayment(
99 | log *slog.Logger,
100 | client *rzpsdk.Client,
101 | ) mcpgo.Tool {
102 | parameters := []mcpgo.ToolParameter{
103 | mcpgo.WithString(
104 | "payment_id",
105 | mcpgo.Description("payment_id is unique identifier of the payment to be retrieved."),
106 | mcpgo.Required(),
107 | ),
108 | }
109 |
110 | handler := func(
111 | ctx context.Context,
112 | r mcpgo.CallToolRequest,
113 | ) (*mcpgo.ToolResult, error) {
114 | arg, ok := r.Arguments["payment_id"]
115 | if !ok {
116 | return mcpgo.NewToolResultError(
117 | "payment id is a required field"), nil
118 | }
119 | id, ok := arg.(string)
120 | if !ok {
121 | return mcpgo.NewToolResultError(
122 | "payment id is expected to be a string"), nil
123 | }
124 |
125 | payment, err := client.Payment.Fetch(id, nil, nil)
126 | if err != nil {
127 | return mcpgo.NewToolResultError(
128 | fmt.Sprintf("fetching payment failed: %s", err.Error())), nil
129 | }
130 |
131 | return mcpgo.NewToolResultJSON(payment)
132 | }
133 |
134 | return mcpgo.NewTool(
135 | "fetch_payment",
136 | "fetch payment details using payment id.",
137 | parameters,
138 | handler,
139 | )
140 | }
141 | ```
142 |
143 | ## Design Principles
144 |
145 | 1. **Minimal Interface Exposure**: The interfaces defined in this package include only methods that are actually used by our application.
146 |
147 | 2. **Proper Error Handling**: Functions return errors instead of panicking, allowing for graceful error handling throughout the application.
148 |
149 | 3. **Implementation Hiding**: The implementation details using `mark3labs/mcp-go` are hidden behind clean interfaces, making future transitions easier.
150 |
151 | 4. **Naming Clarity**: All implementation types are prefixed with `mark3labs` to clearly indicate they are specifically tied to the current library being used.

1 | # Razorpay MCP Server Tools
2 |
3 | This package contains tools for interacting with the Razorpay API via the Model Context Protocol (MCP).
4 |
5 | ## Creating New API Tools
6 |
7 | This guide explains how to add new Razorpay API tools to the MCP server.
8 |
9 | ### Quick Start
10 |
11 | 1. Locate the API documentation at https://razorpay.com/docs/api/
12 | 2. Identify the equivalent function call for the API in the razorpay go sdk.
13 | 3. Create a new tool function in the appropriate file (or create a new file for a new resource type). Add validations for mandatory fields and call the sdk
14 | 5. Register the tool in `server.go`
15 | 6. Update "Available Tools" section in the main README.md
16 |
17 | ### Tool Structure
18 |
19 | Add the tool definition inside pkg/razorpay's resource file. You can define a new tool using this following template:
20 |
21 | ```go
22 | // ToolName returns a tool that [description of what it does]
23 | func ToolName(
24 | log *slog.Logger,
25 | client *rzpsdk.Client,
26 | ) mcpgo.Tool {
27 | parameters := []mcpgo.ToolParameter{
28 | // Parameters defined here
29 | }
30 |
31 | handler := func(
32 | ctx context.Context,
33 | r mcpgo.CallToolRequest,
34 | ) (*mcpgo.ToolResult, error) {
35 | // Parameter validation
36 | // API call
37 | // Response handling
38 | return mcpgo.NewToolResultJSON(response)
39 | }
40 |
41 | return mcpgo.NewTool(
42 | "tool_name",
43 | "A description of the tool. NOTE: Add any exceptions/rules if relevant for the LLMs.",
44 | parameters,
45 | handler,
46 | )
47 | }
48 | ```
49 |
50 | Tool Naming Conventions:
51 | - Fetch methods: `fetch_resource`
52 | - Create methods: `create_resource`
53 | - FetchAll methods: `fetch_all_resources`
54 |
55 | ### Parameter Definition
56 |
57 | Define parameters using the mcpgo helpers. This would include the type, name, description of the parameter and also specifying if the parameter required or not.
58 |
59 | ```go
60 | // Required parameters
61 | mcpgo.WithString(
62 | "parameter_name",
63 | mcpgo.Description("Description of the parameter"),
64 | mcpgo.Required(),
65 | )
66 |
67 | // Optional parameters
68 | mcpgo.WithNumber(
69 | "amount",
70 | mcpgo.Description("Amount in smallest currency unit"),
71 | )
72 | ```
73 |
74 | Available parameter types:
75 | - `WithString`: For string values
76 | - `WithNumber`: For numeric values
77 | - `WithBoolean`: For boolean values
78 | - `WithObject`: For nested objects
79 |
80 | ### Parameter Validation
81 |
82 | Inside the handler function, use the fluent validator pattern for parameter validation. This provides cleaner, more readable code through method chaining:
83 |
84 | ```go
85 | // Create a new validator
86 | v := NewValidator(&r)
87 |
88 | // Create a map for API request parameters
89 | payload := make(map[string]interface{})
90 |
91 | // Validate and add parameters to the payload with method chaining
92 | v.ValidateAndAddRequiredString(payload, "id").
93 | ValidateAndAddOptionalString(payload, "description").
94 | ValidateAndAddRequiredInt(payload, "amount").
95 | ValidateAndAddOptionalInt(payload, "limit")
96 |
97 | // Validate and add common parameters
98 | v.ValidateAndAddPagination(payload).
99 | ValidateAndAddExpand(payload)
100 |
101 | // Check for validation errors
102 | if result, err := validator.HandleErrorsIfAny(); result != nil {
103 | return result, err
104 | }
105 |
106 | // Proceed with API call using validated parameters in payload
107 | ```
108 |
109 | ### Example: GET Endpoint
110 |
111 | ```go
112 | // FetchResource returns a tool that fetches a resource by ID
113 | func FetchResource(
114 | log *slog.Logger,
115 | client *rzpsdk.Client,
116 | ) mcpgo.Tool {
117 | parameters := []mcpgo.ToolParameter{
118 | mcpgo.WithString(
119 | "id",
120 | mcpgo.Description("Unique identifier of the resource"),
121 | mcpgo.Required(),
122 | ),
123 | }
124 |
125 | handler := func(
126 | ctx context.Context,
127 | r mcpgo.CallToolRequest,
128 | ) (*mcpgo.ToolResult, error) {
129 | // Create validator and a payload map
130 | payload := make(map[string]interface{})
131 | v := NewValidator(&r).
132 | ValidateAndAddRequiredString(payload, "id")
133 |
134 | // Check for validation errors
135 | if result, err := validator.HandleErrorsIfAny(); result != nil {
136 | return result, err
137 | }
138 |
139 | // Extract validated ID and make API call
140 | id := payload["id"].(string)
141 | resource, err := client.Resource.Fetch(id, nil, nil)
142 | if err != nil {
143 | return mcpgo.NewToolResultError(
144 | fmt.Sprintf("fetching resource failed: %s", err.Error())), nil
145 | }
146 |
147 | return mcpgo.NewToolResultJSON(resource)
148 | }
149 |
150 | return mcpgo.NewTool(
151 | "fetch_resource",
152 | "Fetch a resource from Razorpay by ID",
153 | parameters,
154 | handler,
155 | )
156 | }
157 | ```
158 |
159 | ### Example: POST Endpoint
160 |
161 | ```go
162 | // CreateResource returns a tool that creates a new resource

214 | handler,
215 | )
216 | }
217 | ```
218 |
219 | ### Registering Tools
220 |
221 | Add your tool to the appropriate toolset in the `NewToolSets` function in [`pkg/razorpay/tools.go`](tools.go):
222 |
223 | ```go
224 | // NewToolSets creates and configures all available toolsets
225 | func NewToolSets(
226 | log *slog.Logger,
227 | client *rzpsdk.Client,
228 | enabledToolsets []string,
229 | readOnly bool,
230 | ) (*toolsets.ToolsetGroup, error) {
231 | // Create a new toolset group
232 | toolsetGroup := toolsets.NewToolsetGroup(readOnly)
233 |
234 | // Create toolsets
235 | payments := toolsets.NewToolset("payments", "Razorpay Payments related tools").
236 | AddReadTools(
237 | FetchPayment(log, client),
238 | // Add your read-only payment tool here
239 | ).
240 | AddWriteTools(
241 | // Add your write payment tool here
242 | )
243 |
244 | paymentLinks := toolsets.NewToolset(
245 | "payment_links",
246 | "Razorpay Payment Links related tools").
247 | AddReadTools(
248 | FetchPaymentLink(log, client),
249 | // Add your read-only payment link tool here
250 | ).
251 | AddWriteTools(
252 | CreatePaymentLink(log, client),
253 | // Add your write payment link tool here
254 | )
255 |
256 | orders := toolsets.NewToolset("orders", "Razorpay Orders related tools").
257 | AddReadTools(
258 | FetchOrder(log, client),
259 | // Add your read-only order tool here
260 | ).
261 | AddWriteTools(
262 | CreateOrder(log, client),
263 | // Add your write order tool here
264 | )
265 |
266 | // If adding a new resource type, create a new toolset:
267 | /*
268 | newResource := toolsets.NewToolset("new_resource", "Razorpay New Resource related tools").
269 | AddReadTools(
270 | FetchNewResource(log, client),
271 | ).
272 | AddWriteTools(
273 | CreateNewResource(log, client),
274 | )
275 | toolsetGroup.AddToolset(newResource)
276 | */
277 |
278 | // Add toolsets to the group
279 | toolsetGroup.AddToolset(payments)
280 | toolsetGroup.AddToolset(paymentLinks)
281 | toolsetGroup.AddToolset(orders)
282 |
283 | return toolsetGroup, nil
284 | }
285 | ```
286 |
287 | Tools are organized into toolsets by resource type, and each toolset has separate collections for read-only tools (`AddReadTools`) and write tools (`AddWriteTools`). This allows the server to enable/disable write operations when in read-only mode.
288 |
289 | ### Writing Unit Tests
290 |
291 | All new tools should have unit tests to verify their behavior. We use a standard pattern for testing tools:
292 |
293 | ```go
294 | func Test_ToolName(t *testing.T) {
295 | // Define API path that needs to be mocked
296 | apiPathFmt := fmt.Sprintf(
297 | "/%s%s/%%s",
298 | constants.VERSION_V1,
299 | constants.PAYMENT_URL,
300 | )
301 |
302 | // Define mock responses
303 | successResponse := map[string]interface{}{
304 | "id": "resource_123",
305 | "amount": float64(1000),
306 | "currency": "INR",
307 | // Other expected fields
308 | }
309 |
310 | // Define test cases
311 | tests := []RazorpayToolTestCase{
312 | {
313 | Name: "successful case with all parameters",
314 | Request: map[string]interface{}{
315 | "key1": "value1",
316 | "key2": float64(1000),
317 | // All parameters for a complete request
318 | },
319 | MockHttpClient: func() (*http.Client, *httptest.Server) {
320 | return mock.NewHTTPClient(
321 | mock.Endpoint{
322 | Path: fmt.Sprintf(apiPathFmt, "path_params") // or just apiPath. DO NOT add query params here.
323 | Method: "POST", // or "GET" for fetch operations
324 | Response: successResponse,
325 | },
326 | )
327 | },
328 | ExpectError: false,
329 | ExpectedResult: successResponse,
330 | },
331 | {
332 | Name: "missing required parameter",
333 | Request: map[string]interface{}{
334 | // Missing a required parameter
335 | },
336 | MockHttpClient: nil, // No HTTP client needed for validation errors
337 | ExpectError: true,
338 | ExpectedErrMsg: "missing required parameter: param1",
339 | },
340 | {
341 | Name: "multiple validation errors",
342 | Request: map[string]interface{}{
343 | // Missing required parameters and/or including invalid types
344 | "optional_param": "invalid_type", // Wrong type for a parameter
345 | },
346 | MockHttpClient: nil, // No HTTP client needed for validation errors
347 | ExpectError: true,
348 | ExpectedErrMsg: "Validation errors:\n- missing required parameter: param1\n- invalid parameter type: optional_param",
349 | },
350 | // Additional test cases for other scenarios
351 | }
352 |
353 | // Run the tests
354 | for _, tc := range tests {
355 | t.Run(tc.Name, func(t *testing.T) {
356 | runToolTest(t, tc, ToolFunction, "Resource Name")
357 | })
358 | }
359 | }
360 | ```
361 |
362 | #### Best Practices while writing UTs for a new Tool
363 |
364 | 1. **Test Coverage**: At minimum, include:
365 | - One positive test case with all parameters (required and optional)
366 | - One negative test case for each required parameter
367 | - Any edge cases specific to your tool
368 |
369 | 2. **Mock HTTP Responses**: Use the `mock.NewHTTPClient` function to create mock HTTP responses for Razorpay API calls.
370 |
371 | 3. **Validation Errors**: For parameter validation errors, you don't need to mock HTTP responses as these errors are caught before the API call.
372 |
373 | 4. **Test API Errors**: Include at least one test for API-level errors (like invalid currency, not found, etc.).
374 |
375 | 5. **Naming Convention**: Use `Test_FunctionName` format for test functions.
376 |
377 | 6. Use the resource URLs from [Razorpay Go sdk constants](https://github.com/razorpay/razorpay-go/blob/master/constants/url.go) to specify the apiPath to be mocked.
378 |
379 | See [`payment_links_test.go`](payment_links_test.go) for a complete example of tool tests.
380 |
381 | ### Updating Documentation
382 |
383 | After adding a new tool, Update the "Available Tools" section in the README.md in the root of the repository
384 |
385 | ### Best Practices
386 |
387 | 1. **Consistent Naming**: Use consistent naming patterns:
388 | - Fetch methods: `fetch_resource`
389 | - Create methods: `create_resource`
390 | - FetchAll methods: `fetch_all_resources`
391 |
392 | 2. **Error Handling**: Always provide clear error messages
393 |
394 | 3. **Validation**: Always validate required parameters and collect all validation errors before returning using fluent validator pattern.
395 | - Use the `NewValidator` to create a validator
396 | - Chain validation methods (`ValidateAndAddRequiredString`, etc.)
397 | - Return formatted errors with `HandleErrorsIfAny()`
398 |
399 | 4. **Documentation**: Describe all the parameters clearly for the LLMs to understand.
400 |
401 | 5. **Organization**: Add tools to the appropriate file based on resource type
402 |
403 | 6. **Testing**: Test your tool with different parameter combinations
```

181 | }
182 | ```
183 |
184 | Learn more about MCP servers in VS Code's [agent mode documentation](https://code.visualstudio.com/docs/copilot/chat/mcp-servers).
185 |
186 | ## Authentication
187 |
188 | The Remote MCP Server uses merchant token-based authentication. To generate your merchant token:
189 |
190 | 1. Go to the [Razorpay Dashboard](https://dashboard.razorpay.com/) and navigate to Settings > API Keys
191 | 2. Locate your API Key and API Secret:
192 | - API Key is visible on the dashboard
193 | - API Secret is generated only once when you first create it. **Important:** Do not generate a new secret if you already have one
194 |
195 | 3. Generate your merchant token by running this command in your terminal:
196 | ```bash
197 | echo <RAZORPAY_API_KEY>:<RAZORPAY_API_SECRET> | base64
198 | ```
199 | Replace `<RAZORPAY_API_KEY>` and `<RAZORPAY_API_SECRET>` with your actual credentials
200 |
201 | 4. Copy the base64-encoded output - this is your merchant token for the Remote MCP Server
202 |
203 | > **Note:** For local MCP Server deployment, you can use the API Key and Secret directly without generating a merchant token.
204 |
205 |
206 | ## Local MCP Server
207 |
208 | For users who prefer to run the MCP server on their own infrastructure or need access to all tools (including those restricted in the remote server), you can deploy the server locally.
209 |
210 | ### Prerequisites
211 |
212 | - Docker
213 | - Golang (Go)
214 | - Git
215 |
216 | To run the Razorpay MCP server, use one of the following methods:
217 |
218 | ### Using Public Docker Image (Recommended)
219 |
220 | You can use the public Razorpay image directly. No need to build anything yourself - just copy-paste the configurations below and make sure Docker is already installed.
221 |
222 | > **Note:** To use a specific version instead of the latest, replace `razorpay/mcp` with `razorpay/mcp:v1.0.0` (or your desired version tag) in the configurations below. Available tags can be found on [Docker Hub](https://hub.docker.com/r/razorpay/mcp/tags).
223 |
224 |
225 | #### Usage with Claude Desktop
226 |
227 | This will use the public razorpay image
228 |
229 | Add the following to your `claude_desktop_config.json`:
230 |
231 | ```json
232 | {
233 | "mcpServers": {
234 | "razorpay-mcp-server": {
235 | "command": "docker",
236 | "args": [
237 | "run",
238 | "--rm",

336 |
337 | ### Build from Docker (Alternative)
338 |
339 | You need to clone the Github repo and build the image for Razorpay MCP Server using `docker`. Do make sure `docker` is installed and running in your system.
340 |
341 | ```bash
342 | # Run the server
343 | git clone https://github.com/razorpay/razorpay-mcp-server.git
344 | cd razorpay-mcp-server
345 | docker build -t razorpay-mcp-server:latest .
346 | ```
347 |
348 | Once the razorpay-mcp-server:latest docker image is built, you can replace the public image(`razorpay/mcp`) with it in the above configurations.
349 |
350 | ### Build from source
351 |
352 | You can directly build from the source instead of using docker by following these steps:
353 |
354 | ```bash
355 | # Clone the repository
356 | git clone https://github.com/razorpay/razorpay-mcp-server.git
357 | cd razorpay-mcp-server
358 |
359 | # Build the binary
360 | go build -o razorpay-mcp-server ./cmd/razorpay-mcp-server
361 | ```
362 | Once the build is ready, you need to specify the path to the binary executable in the `command` option. Here's an example for VS Code settings:
363 |
364 | ```json
365 | {
366 | "razorpay": {
367 | "command": "/path/to/razorpay-mcp-server",
368 | "args": ["stdio","--log-file=/path/to/rzp-mcp.log"],
369 | "env": {
370 | "RAZORPAY_KEY_ID": "<YOUR_ID>",
371 | "RAZORPAY_KEY_SECRET" : "<YOUR_SECRET>"
372 | }
373 | }
374 | }
375 | ```
376 |
377 | ## Configuration
378 |
379 | The server requires the following configuration:
380 |
381 | - `RAZORPAY_KEY_ID`: Your Razorpay API key ID
382 | - `RAZORPAY_KEY_SECRET`: Your Razorpay API key secret
383 | - `LOG_FILE` (optional): Path to log file for server logs
384 | - `TOOLSETS` (optional): Comma-separated list of toolsets to enable (default: "all")
385 | - `READ_ONLY` (optional): Run server in read-only mode (default: false)
386 |
387 | ### Command Line Flags
388 |
389 | The server supports the following command line flags:
390 |
391 | - `--key` or `-k`: Your Razorpay API key ID
392 | - `--secret` or `-s`: Your Razorpay API key secret
393 | - `--log-file` or `-l`: Path to log file
394 | - `--toolsets` or `-t`: Comma-separated list of toolsets to enable
395 | - `--read-only`: Run server in read-only mode
396 |
397 | ## Debugging the Server
398 |
399 | You can use the standard Go debugging tools to troubleshoot issues with the server. Log files can be specified using the `--log-file` flag (defaults to ./logs)

18 |
19 | We use Cursor to contribute - our AI developer. Look at `~/.cusor/rules`. It understands the standards we have defined and codes with that.
20 |
21 | ## Development Process
22 |
23 | We use a fork-based workflow for all contributions:
24 |
25 | 1. **Fork the repository**: Start by forking the [razorpay-mcp-server repository](https://github.com/razorpay/razorpay-mcp-server) to your GitHub account.
26 |
27 | 2. **Clone your fork**: Clone your fork to your local machine:
28 | ```bash
29 | git clone https://github.com/YOUR-USERNAME/razorpay-mcp-server.git
30 | cd razorpay-mcp-server
31 | ```
32 |
33 | 3. **Add upstream remote**: Add the original repository as an "upstream" remote:
34 | ```bash
35 | git remote add upstream https://github.com/razorpay/razorpay-mcp-server.git
36 | ```
37 |
38 | 4. **Create a branch**: Create a new branch for your changes:
39 | ```bash
40 | git checkout -b username/feature
41 | ```
42 | Use a descriptive branch name that includes your username followed by a brief feature description.
43 |
44 | 5. **Make your changes**: Implement your changes, following the code style guidelines.
45 |
46 | 6. **Write tests**: Add tests for your changes when applicable.
47 |
48 | 7. **Run tests and linting**: Make sure all tests pass and the code meets our linting standards.
49 |
50 | 8. **Commit your changes**: Make commits with clear messages following this format:
51 | ```bash
52 | git commit -m "[type]: description of the change"
53 | ```
54 | Where `type` is one of:
55 | - `chore`: for tasks like adding linter config, GitHub Actions, addressing PR review comments, etc.
56 | - `feat`: for adding new features like a new fetch_payment tool
57 | - `fix`: for bug fixes
58 | - `ref`: for code refactoring
59 | - `test`: for adding UTs or E2Es
60 |
61 | Example: `git commit -m "feat: add payment verification tool"`
62 |
63 | 9. **Keep your branch updated**: Regularly sync your branch with the upstream repository:
64 | ```bash
65 | git fetch upstream
66 | git rebase upstream/main
67 | ```
68 |
69 | 10. **Push to your fork**: Push your changes to your fork:
70 | ```bash
71 | git push origin username/feature
72 | ```
73 |
74 | 11. **Create a Pull Request**: Open a pull request from your fork to the main repository.
75 |
76 | ## Pull Request Process
77 |
78 | 1. Fill out the pull request template with all relevant information.
79 | 2. Link any related issues in the pull request description.
80 | 3. Ensure all status checks pass.
81 | 4. Wait for review from maintainers.
