This is a mock/showcase library, not a functional MCP server. The three tools (create_or_update_file, get_hackathon_overview, search_notion) are defined in src/mocks/index.ts as data structures within MOCK_MCP_SERVERS array, not as actual MCP tool implementations. No tool registration, no handler functions, no actual protocol implementation visible. Descriptions are present but generic (34 - 72 chars, below the 50 - 200 char LLM-optimized baseline). Schemas are partially visible in the mock data structure but lack proper JSON Schema format with explicit type declarations. No error handling, no output schema documentation, no parameter validation. This is a reference/documentation artifact, not a production MCP server.

• Implement actual MCP tool handlers with proper request/response routing. Replace mock data structures with real tool registration using the MCP SDK.
• Expand tool descriptions to 50 - 200 characters. Include WHAT the tool does, WHEN to use it, and what it returns. Example: 'Creates or updates a file in a GitHub repository. Use this to commit code changes, update documentation, or sync configuration. Returns the commit SHA and file URL.'
• Add comprehensive parameter descriptions with format constraints. Example: 'path: File path in the repository (e.g. src/main.ts). Must be relative to repo root, max 255 chars.'
• Document output schemas for each tool. Specify field names, types, and whether results are paginated. Example: 'Returns {commit_sha: string, file_url: string, updated_at: ISO8601}.'
• Add error handling with recovery guidance. Example: 'If file not found, try search_files() first. If permission denied, verify GitHub token has repo:write scope.'
