Claude Model Context Protocol Tools and Servers

MCP Tools and Servers

Claude's Model Context Protocol (MCP) makes it easy to connect external tools to Claude (or MCP-compatible services).

Here's some of the stuff I've hacked together so far..

CLI to convert old projects into Claude tools

_{MCP converter converting an old project into a Claude tool}

I made a CLI tool called mcp-convert to turn old codebases into Claude tools. It let's you use AI to extract business logic from an existing codebase and quickly make an MCP tool. It's based on a technique I've used several times to turn some of my old projects into personal Claude tools, which is documented in this post. I figured I could make a tool that can automatically cut a few steps out of that process.

iMessage MCP Server

An MCP server that lets Claude read and send messages in iMessage. I wrote a post about how to implement this here.

Source code available on my Github here

BART MCP Server

_{Claude using our new tool}

A simple MCP server to fetch BART transit data. I wrote about how I used ChatGPT O1 to create this from a previous project in this post.
