Response Format Structure + +One of the most significant discoveries during our testing was the unexpected and complex response format from the GitHub MCP Server Binary implementation. + +### Expected vs. Actual Response Format + +**Expected Format (Based on Documentation):** +```json +{ + "jsonrpc": "2.0", + "id": "request-id", + "result": { + // Direct tool result data + } +} +``` + +**Actual Format (Discovered During Testing):** +```json +{ + "jsonrpc": "2.0", + "id": "request-id", + "result": { + "content": [ + { + "type": "text", + "text": "{\"full_json_response_as_string\"}" + } + ] + } +} +``` + +### Key Insights: +- The actual result data is nested in a JSON string within `content[0].text` +- This string needs to be parsed as JSON to access the actual data +- Not all responses follow this format - some tools return direct JSON results +- A robust parser must handle both formats gracefully + +### Implementation Solution + +We developed a flexible response parser that handles the different formats: + +```python +def parse_response(response): + """Parse a response from the GitHub MCP Server.""" + if "result" in response: + result = response["result"] + # Check if result contains content field (the new format) + if "content" in result and isinstance(result["content"], list): + for item in result["content"]: + if item.get("type") == "text": + text = item.get("text", "") + # Try to parse the text as JSON + try: + return json.loads(text) + except: + # If it's not valid JSON, return the text as is + return text + # If no content field or parsing failed, return the result as is + return result + + # Return empty dict if no result found + return {} +``` + +## 2. Tool Names and Discoverability + +Another significant discovery was the discrepancy between documented tool names and actual tool names recognized by the server. + +### Tool Name Discrepancies + +| Documentation | Actual Tool Name | Notes | +|---------------|-----------------|-------| +| `get_repo` | Not available | Use `search_repositories` instead | +| `list_branches` | Available | Works as documented | +| `create_branch` | Available | Works as documented | +| `get_file_contents` | Available | Works as documented | +| `create_or_update_file` | Available | Works as documented | +| `create_pull_request` | Available | Works as documented | + +### Tool Discovery Method + +We created a dedicated script `list_tools.py` to discover all available tools: + +```python +# Create a request to list all available tools +request = { + "jsonrpc": "2.0", + "id": "1", + "method": "tools/list", + "params": {} +} +``` + +This approach revealed the complete list of available tools, their descriptions, and parameters. + +### Best Practices for Tool Discovery + +1. **Always use `tools/list` first**: Before integrating with the GitHub MCP Server, always query the available tools +2. **Document tool parameters**: Document the required and optional parameters for each tool +3. **Create helper functions**: Create wrapper functions for each tool to simplify their use +4. **Handle errors gracefully**: Add specific error handling for each tool + +## 3. Handling Various Response Types + +Different endpoints return responses in different formats, requiring flexible parsing logic. + +### Response Type Variations + +1. **List Responses**: Some tools (e.g., `list_branches`) return direct arrays +2. **Dictionary with Items**: Others (e.g., `search_repositories`) return dictionaries with an `items` array +3. **Single Object**: Some (e.g., `get_me`) return a single object +4. **Nested Content**: Many responses embed the result in the `content[0].text` field as a string + +### Example of Type-Safe Handling + +```python +# Handle different response formats for branches +branches = [] +if isinstance(branches_response, list): + branches = branches_response +elif isinstance(branches_response, dict) and "items" in branches_response: + branches = branches_response.get("items", []) +``` + +### Response Type Best Practices + +1. **Always use type checking**: Never assume a response is a particular type +2. **Use defensive programming**: Handle missing fields gracefully +3. **Provide fallbacks**: Always have default values if data extraction fails +4. **Log unexpected formats**: Log unusual response formats to assist debugging + +## 4. Authentication Best Practices + +We developed secure token handling approaches for the GitHub MCP Server. + +### Token Storage Methods + +1. **Environment Variables**: Less secure but simpler for one-time use + ```bash + export GITHUB_PERSONAL_ACCESS_TOKEN=your_token_here + ``` + +2. **Token File**: More secure for persistent use + ```bash + echo "your_token_here" > ~/.github_token + chmod 600 ~/.github_token # Restrict permissions + ``` + +### Secure Token Retrieval + +We created a dedicated token helper module that follows security best practices: + +```python +def get_github_token(): + """Get GitHub token from token file or environment variable.""" + # Try token file first + if os.path.exists(TOKEN_FILE): + with open(TOKEN_FILE, "r") as f: + token = f.read().strip() + if token: + return token + + # Try environment variable as fallback + token = os.environ.get("GITHUB_PERSONAL_ACCESS_TOKEN") + if token: + return token + + # No token found + return None +``` + +### Authentication Best Practices + +1. **Never hardcode tokens**: Always use environment variables or secure token files +2. **Check file permissions**: Ensure token files have restricted permissions (0600) +3. **Use library-based auth**: Prefer to use established libraries for authentication +4. **Prompt when missing**: Provide clear instructions when authentication fails +5. **Validate tokens early**: Verify tokens work before attempting multiple operations + +## 5. Pull Request Workflow Implementation + +We implemented a complete pull request workflow that demonstrates the full capabilities of the GitHub MCP Server. + +### Complete PR Workflow Steps + +1. **Get Authenticated User**: Verify authentication and get user information +2. **Search Repository**: Locate the specific repository using `search_repositories` +3. **List Branches**: Get the default branch and its SHA +4. **Create Branch**: Create a new branch from the default branch +5. **Create File**: Add a new file to the branch +6. **Create PR**: Create a pull request from the new branch to the default branch + +### Key Workflow Components + +The workflow is encapsulated in a client class that handles server communication: + +```python +class GitHubMCPClient: + """Client for communicating with the GitHub MCP Server.""" + + def __init__(self, binary_path): + """Initialize the client.""" + self.binary_path = binary_path + self.process = None + self.request_id = 0 + + # ...methods for server management... + + def call_tool(self, name, arguments): + """Call a tool in the GitHub MCP Server.""" + # ...implementation... + + # ...high-level API methods... + + def create_pull_request(self, owner, repo, title, head, base, body, draft=False): + """Create a new pull request.""" + return self.call_tool("create_pull_request", { + "owner": owner, + "repo": repo, + "title": title, + "head": head, + "base": base, + "body": body, + "draft": draft + }) +``` + +## 6. Common Issues and Troubleshooting + +Based on our testing experience, we documented common issues and solutions. + +### Authentication Issues + +- **Token Not Found**: Ensure the token exists and is accessible +- **Invalid Token**: Verify the token has the required scopes +- **Token File Permissions**: Ensure token file has correct permissions (0600) + +### Response Parsing Issues + +- **Missing Result**: Some responses may not include a result field +- **Content Type**: Check for the correct content type +- **Nested Structure**: Handle deeply nested response structures +- **List vs. Dict**: Be prepared for different response data structures + +### Tool Name Issues + +- **Incorrect Tool Name**: Verify tool names with `tools/list` +- **Missing Parameters**: Check required parameters for each tool +- **Parameter Format**: Ensure parameters are in the correct format + +### Server Communication Issues + +- **Server Not Starting**: Check for binary executable permissions +- **Request Format**: Ensure requests follow the JSON-RPC 2.0 format +- **Response Timeout**: Handle timeouts gracefully +- **Process Management**: Properly terminate processes when done + +## 7.
