pyro-mcp

pyro-mcp is a minimal Python library that exposes an MCP-compatible server with one static tool.

v0.0.1 Features

• Official Python MCP SDK integration.
• Public server factory: pyro_mcp.create_server().
• One static MCP tool: hello_static.
• Runnable demonstration script.
• Project automation via Makefile, pre-commit, ruff, mypy, and pytest.

Requirements

• Python 3.12+
• uv installed

Setup

make setup

This installs runtime and development dependencies into .venv.

Run the demo

make demo

Expected output:

{
  "message": "hello from pyro_mcp",
  "status": "ok",
  "version": "0.0.1"
}

Run the Ollama tool-calling demo

Start Ollama and ensure the model is available (defaults to llama:3.2-3b):

ollama serve
ollama pull llama:3.2-3b

Then run:

make ollama-demo

You can also run make ollama demo to execute both demos in one command. The Make target defaults to model llama:3.2-3b and can be overridden:

make ollama-demo OLLAMA_MODEL=llama3.2:3b

Run checks

make check

make check runs:

• ruff lint checks
• mypy type checks
• pytest (with coverage threshold configured in pyproject.toml)

Run MCP server (stdio transport)

make run-server

Pre-commit

Install hooks:

make install-hooks

Hooks run ruff, mypy, and pytest on each commit.
