Claude Bridge

<!-- mcp-name: io.github.constripacity/claude-code-bridge -->

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.

It does not call a model API and does not require agents to share a filesystem or process. Claude Code motivated the project, but the core is MCP-based and is not coupled to Anthropic.

Forward-build notice: this source tree identifies as 1.2.0.dev1. It is

a development build beyond the latest stable PyPI release. Review the

changelog

and 0.9-to-1.2 migration guide

before replacing a stable deployment.

Why use it?

shell access.

  • Keep agents on Windows, macOS, Linux, or a remote host in their own sessions.
  • Send work, results, review requests, and artifact references without remote
  • Use durable history and consumer cursors to recover after a client restart.
  • Retry sends safely with an idempotency key.
  • Observe the same relay through MCP, a browser dashboard, the TUI, or REST.
  • Run locally or across a private LAN/tailnet with an explicit security policy.

Claude Bridge is a transport, not an autonomous orchestrator. Receiving a message never authorizes an agent to execute it.

Transports

The automated suite performs a real MCP SDK handshake against /mcp. Vendor clients are not launched in CI. See the evidence-based compatibility matrix.

Architecture

flowchart TB
    A["Claude Code / Codex / MCP client"] -->|"Streamable HTTP /mcp"| B["Claude Bridge"]
    C["Local MCP client"] -->|"stdio"| B
    D["Dashboard / TUI / script"] -->|"REST + event SSE"| B
    B --> E[("SQLite")]

Messages and live-notification records are committed to SQLite in one transaction. HTTP processes poll that durable outbox (500 ms by default), so a write from a separate stdio process is propagated to connected dashboard/TUI event streams. Durable channel history remains authoritative across restarts.

Install

python -m pip install claude-code-bridge

Install the terminal UI as well:

python -m pip install "claude-code-bridge[tui]"

The PyPI distribution is named claude-code-bridge because claude-bridge was already assigned to an unrelated project. The command and Python package remain claude-bridge and claude_bridge.

From a source checkout:

git clone https://github.com/constripacity/Claude-Bridge.git
cd Claude-Bridge
python -m pip install -e ".[dev]"

Start safely

Local-only HTTP mode is the default:

claude-bridge

This listens on 127.0.0.1:8765. Open http://127.0.0.1:8765/ for the dashboard or connect an MCP client to http://127.0.0.1:8765/mcp.

Local stdio mode does not open a network listener:
