Claude Code Matrix Channel Plugin Built in Rust with E2EE Support
A developer has created a Matrix channel plugin for Claude Code, filling a gap since the official channels only shipped with Discord and Telegram support. The plugin was built in Rust using Claude Code (CC) and took approximately 24 hours to develop.
Development Process and Key Features
The developer used the channel itself to build the channel, going back and forth on the repository, checking GitHub Actions, and debugging end-to-end encryption (E2EE) from their phone while Claude ran on a VPS. The E2EE implementation was particularly challenging, requiring significant back-and-forth to get the Rust matrix-sdk to properly decrypt files in encrypted direct messages.
Technical Specifications
- Text, files, and images with E2EE decryption
- Reply threading, reactions, and message editing
- Typing indicator, chunking, and bot commands
- Pairing and access control
- Compatible with any Matrix homeserver (Synapse, Conduit, etc.)
- Rust binary, approximately 14MB
- MIT licensed and free
- Prebuilt binaries available for Linux, macOS, and Windows
The developer uses the channel daily and plans to keep it updated. The source code is available on GitHub at https://github.com/IA-PieroCV/cc_matrix_channel, and feedback is welcome from anyone who tries it.
