Claude Bridge MCP Server

A local-first, cross-machine message bus for independent coding agents. Claude Bridge lets coding-agent sessions on different machines exchange ordered messages through named channels. The relay is self-hosted, uses SQLite by default, and exposes MCP, a small JSON API, a dashboard, and a terminal UI.

People who work with developer tools, multi agent and textual and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

Claude Code

claude mcp add constripacity-claude-bridge -- uvx claude-code-bridge

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "constripacity-claude-bridge": {
      "command": "uvx",
      "args": [
        "claude-code-bridge"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

license MIT - declared in the repository

pypi package claude-code-bridge - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.constripacity is GitHub-verified and matches the repo owner
