Write a poem MCP

This is a simple example to show how to write a MCP tool with Mellea and instruct-validate-repair. Being able to speak the tool language allows you to integrate with Claude Desktop, Langflow, ...

See code in mcp_example.py

Run the example

You need to install the mcp package:

uv pip install "mcp[cli]"

and run the example in MCP debug UI:

uv run mcp dev docs/examples/mcp/mcp_example.py

Use in Langflow

Follow this path (JSON) to use it in Langflow: https://docs.langflow.org/mcp-client#mcp-stdio-mode

The JSON to register your MCP tool is the following. Be sure to insert the absolute path to the directory containing the mcp_example.py file:

{
  "mcpServers": {
    "mellea_mcp_server": {
      "command": "uv",
      "args": [
        "--directory",
        "<ABSOLUTE PATH>/mellea/docs/examples/mcp",
        "run",
        "mcp",
        "run",
        "mcp_example.py"
      ]
    }
  }
}
