Overview

What is toyMCP To-Do List Server?

toyMCP To-Do List Server is a simple example server that implements a To-Do list CRUD API using the Model Context Protocol (MCP) concepts, specifically JSON-RPC 2.0 over HTTP. It uses Node.js, Express, and PostgreSQL (via Docker) for persistence, and includes an AI-powered agent framework for natural language interaction.

How to use toyMCP To-Do List Server?

Set up prerequisites: Node.js, npm, Docker, and Docker Compose. Clone the repository, run npm install, start PostgreSQL with docker compose up -d db, then start the server with npm start. The JSON-RPC endpoint is at http://localhost:3000/rpc. Authenticate by logging in at /auth/login with username and password to obtain a JWT token, then include it as an Authorization: Bearer <token> header in subsequent requests. Use curl to call methods like todo.list, todo.add, todo.remove, or mcp.discover. For natural language management, use the agent framework in the agent-framework/ directory.

Frequently asked questions

What is the default port and endpoint?

The server listens on port 3000 by default (configurable via the `PORT` environment variable), and the JSON-RPC endpoint is at `/rpc`.

How do I authenticate?

Send a POST request to `/auth/login` with your username and password. Copy the token from the response, then include it as an `Authorization: Bearer <token>` header in all subsequent requests to protected endpoints.

What are the available JSON-RPC methods?

The methods are `todo.list`, `todo.add`, `todo.remove`, and `mcp.discover` (which describes the service and its available methods).

What are the dependencies?

The server requires Node.js, npm, Docker, and Docker Compose for the PostgreSQL database. The agent framework can use local Ollama or OpenAI cloud models.

How can I reset the database?

Use the `clean_start.sh` script, which stops and removes the database container, restarts it, and then starts the server fresh.
