Claude Code Redis Channels (claude-code-redis-channels)

A minimal Redis-backed channel integration for Claude Code, implemented in Python.

Overview

This package provides an MCP (Model Context Protocol) server that enables Claude Code to receive events and send replies via Redis. It supports multi-agent scenarios, inter-agent synchronization, and a synchronous "await" bridge for external callers.

Features

• Python-Native: Built with mcp Python SDK and asyncio.
• Multi-Agent Support: Route messages to specific agents via unique AGENT_ID.
• Two-Way Support: Reply to messages from Claude Code using a Redis reply tool.
• Sync-over-Async: Await an agent's response via a blocking HTTP endpoint (GET /await/{agent_id}).
• Inter-Agent Coordination: Agents can wait for each other indefinitely using the await_message tool.
• Minimal Dependencies: Only requires mcp, redis, starlette, and uvicorn.

Setup

Requirements

• Python 3.12+
• uv (recommended)

Installation

uv tool install .

Configuration

Add the server to your .mcp.json:

{
  "mcpServers": {
    "redis-channel": {
      "command": "uv",
      "args": ["run", "--package", "claude-code-redis-channels", "redis-channel"],
      "env": {
        "REDIS_URI": "redis://localhost:6379",
        "AGENT_ID": "dallas-main",
        "HTTP_PORT": "8000"
      }
    }
  }
}

Await Endpoint (Sync Bridge)

The server can optionally host an HTTP endpoint that blocks until the agent sends a reply. This allows CLI scripts or microservices to "wait" for Claude to finish.

# In one terminal, wait for Claude's next message (indefinite wait)
curl "http://localhost:8000/await/dallas-main"

# In Claude Code:
# > reply chat_id="123" text="Task complete!"

Usage

Start Claude Code with the development channel flag:

claude --dangerously-load-development-channels server:redis-channel

Sending Messages

Send a JSON payload to a specific agent's inbox:

redis-cli PUBLISH claude:inbox:dallas-main '{"content": "Hello Dallas!", "meta": {"chat_id": "123"}}'

Inter-Agent Communication

Agents can wait for each other indefinitely within their session: await_message(target_agent_id="other-agent")

Testing

A manual integration test script is included in scripts/test_mcp.py. It simulates a Claude Code session and verifies Redis communication.

uv run scripts/test_mcp.py

Note: Requires a running Redis instance on localhost:6379.
