README

mcp-toy

Toy project to explore the MCP capability

Following the example here.

MCP Servers

MCP servers can provide 3 main types of capabilities:

Resources - File-like data that can be read by clients
Tools - Functions that can be called by LLM
Prompts - Pre-written templates that can help users accomplish specific tasks

Claude desktop integration

Run mcp install server.py to load the MCP server to Claude, the corresponding config in ~/Library/Application\ Support/Claude/claude_desktop_config.json will be updated. Here is an example:

{
  "mcpServers": {
    "weather": {
      "command": "uv",
      "args": [
        "run",
        "--with",
        "mcp[cli]",
        "mcp",
        "run",
        "/Users/xiangshiyin/Documents/Coding/mcp-toy/server.py"
      ]
    }
  }
}

Development mode

Run uv run mcp dev server.py to inspect the MCP server
