Infrahub MCP Server

Connects AI assistants to Infrahub over the open MCP standard, so agents can read and (optionally) change infrastructure state through a consistent, audited, human-approved interface.

• Runtime: Python 3.13, FastMCP, Infrahub SDK, Pydantic 2, Starlette
• Testing: pytest, pytest-asyncio
• Linting: ruff, mypy, pylint, yamllint
• Docs: Docusaurus (.mdx in docs/docs/), rumdl for markdown linting
• Package Manager: uv
