Kit now speaks MCP

We shipped something new: kit for MCP.

It’s kit, but as an MCP server optimized for local dev, with new features like documentation research and ast-grep. It improves your local dev experience.

The tools inside

We didn’t just port kit to MCP. We built tools specifically for how AI assistants think:

• deep_research_package - Pulls documentation from multiple sources, understands how libraries actually work
• grep_ast - Searches by code structure, not just text (finds all React components, all error handlers, etc.)
• review_diff - Analyzes changes and their impact across the codebase

And more. Each tool returns structured data the AI can reason about.

Local LLMs work too

If you run Ollama or another local LLM, kit MCP uses it for documentation research. Your code stays on your machine.

The philosophy stays the same

When we open sourced kit, I wrote about building blocks being free and not gatekeeping the fundamentals of developer tools.

Kit MCP is the same idea. MIT licensed, so hack on it, make it better, and build your own tools on top.
