karbon

cross-surface memory + local dev access for Claude.

This is the karbon cloud MCP origin. Humans usually don't visit it directly — Claude Web and Claude Code connect here via a Custom Connector. If you were sent here, you're in the right place.

Connect Claude Web

  1. Sign in on claude.ai
  2. Settings → Connectors → Custom Connectors → Add
  3. Paste your connector URL (ends in /mcp/<your-project>)
  4. Approve the OAuth consent

Connect Claude Code

claude mcp add --transport http karbon \
  https://mcp.karbon.sh/mcp/<your-project>

Get a connector URL

go install github.com/hazerun/karbon/cmd/karbon@latest
karbon cloud login
karbon cloud project create my-app
karbon daemon start

That last step opens a WebSocket tunnel to this host so Claude can read your files and run commands through read_file / write_file / exec — safely, via Shield's policy rail.
