This MCP server lets Claude Code talk to Thunderbird through a local bridge, enabling you to search emails and contacts, read messages, and draft replies directly from your Claude workflow. It runs entirely locally, with a small HTTP bridge inside Thunderbird and a standard stdio-based MCP connection from your client.

How to use

You connect to the Thunderbird MCP server from your MCP client using a standard stdio bridge. Your client talks to the bridge process on your machine, which in turn communicates with Thunderbird via a local HTTP server. You can search messages, read full emails, look up contacts, list calendars, and compose or reply to messages. All compose actions open a Thunderbird window for review before sending, so nothing is sent automatically.

How to install

Prerequisites: you need a working Node.js runtime on your system.

# Build the Thunderbird MCP extension components
./scripts/build.sh

# Install the Thunderbird MCP extension
./scripts/install.sh

Restart Thunderbird to load the new extension.

## Additional setup and configuration

Configure Claude Code to use the Thunderbird MCP bridge. Create or update your Claude Code configuration file to point at the local bridge, using a stdio connection.
