FastAPI Server
Provides a minimalist FastAPI server implementation designed to mimic a subset of the Model Context Protocol (MCP) functionality.
About
This project offers a lightweight FastAPI server that emulates key aspects of the Model Context Protocol (MCP). It features both a straightforward RESTful echo endpoint and a robust JSON-RPC 2.0 interface. The RPC endpoint supports discovering available tools (`mcp.list_tools`) and executing them (`mcp.call_tool`), demonstrating functionality with built-in examples like `echo`, `uppercase`, `query_manse` for database interaction, and `calc_daewoon` for date calculations. Complete with Pydantic models for structured data handling, basic logging, and comprehensive tests, it serves as an excellent starting point for building or integrating with MCP-style services.
Key Features
- Echo-style REST endpoint returning structured responses
- JSON-RPC 2.0 endpoint supporting tool listing and execution
- Includes example tools for text manipulation, database query, and date calculations
- Uses Pydantic models for request and response validation
- Includes basic logging and pytest for comprehensive testing
- 0 GitHub stars
Use Cases
- Learning FastAPI server implementation with structured RPC and database integration patterns
- Exposing internal Python functions or microservices via a standardized JSON-RPC API
- Developing and testing services compatible with the Model Context Protocol
