What is the Claude MCP server?

If you already use Claude, the claude mcp server is the piece that lets your assistant work with it directly. MCP relay so Claude Code agents on different machines can exchange messages via named channels.

What the server does

Claude Code's native Agent Teams coordinate multiple instances on the same machine. Claude Bridge fills the gap — it lets Claude Code agents on different machines communicate in real time over a shared MCP relay server.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • bridge_send — Send a message to a named channel
  • bridge_receive — Read messages — pass since_id for incremental polling
  • bridge_channels — List all active channels and message counts
  • bridge_ping — Health check + server stats
  • bridge_clear — Clear all messages from a channel
  • bridge_status — Cross-channel overview with recent messages

Installation

claude-code-bridge on PyPI is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Credentials and setup notes

Configuration is passed through the environment: CLAUDE_BRIDGE_AUTH_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

  • Python 3.10+ - mcp, starlette, uvicorn, anyio, sse-starlette (declared in pyproject.toml; installed automatically by pip install claude-bridge) - A reachable network path between machines — localhost, LAN, Tailscale, or any other route (see Networking) ---

Where it fits

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Claude's toolset — bridge_send, bridge_receive, bridge_channels and 3 more — is a fair guide to whether it matches your workflow. It is maintained by constripacity; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Claude to MCP-compatible AI assistants such as Claude and Cursor, exposing 6 tools (bridge_send, bridge_receive, bridge_channels, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Claude directly.
