Add cowork-to-code-bridge to the MCP registry

[abhinaykrupa]

Problem

Agents and MCP clients using Claude need a way to execute code locally without:

• Separate API key management
• Cloud-only execution (losing repo + env context)
• Additional billing outside existing Claude subscription

This gap limits local-first agent workflows and MCP-based tooling.

Solution: cowork-to-code-bridge — MCP Server for Local Claude Code

cowork-to-code-bridge is a production-ready MCP server exposing Claude Code as a local execution backend.

Key Features

• ✅ No API keys — uses Claude subscription on the user's machine
• ✅ Full local context — agent has access to repos, shell, MCPs, environment
• ✅ MCP standard — JSONRPC 2.0 over stdio (native protocol)
• ✅ Zero network ports — file-based queue, token-authenticated
• ✅ Lightweight — <1MB, minimal dependencies
• ✅ Production-ready — 570 lines + 9 unit tests + comprehensive docs

How It Works

Agent/MCP client config:

{
  "providers": {
    "claude-code-bridge": {
      "type": "mcp",
      "command": "cowork-to-code-bridge-mcp",
      "args": ["--stdio"],
      "env": {"BRIDGE_ROOT": "$HOME/.cowork-to-code-bridge"}
    }
  }
}

Agent escalates work:

response = agent.escalate(
    tool="escalate_to_claude",
    request="Debug the API failure and propose fix",
    wait_seconds=600
)

Three MCP Tools

1. escalate_to_claude — Hand task to Claude Code, get result asynchronously
2. run_script — Execute whitelisted scripts directly
3. list_bridge_scripts — Discover available scripts

Why This Matters

Official MCP server registry. Being listed = discoverability for all MCP clients.

This fills a gap in the MCP registry: there's no canonical "local code execution" backend. Adding cowork-to-code-bridge as a reference implementation helps MCP clients (agents, IDEs, tools) discover the pattern for local Claude integration.

Reference Implementation

• GitHub: https://github.com/abhinaykrupa/cowork-to-code-bridge
• MCP Docs: https://github.com/abhinaykrupa/cowork-to-code-bridge/blob/main/docs/MCP_SERVER_IMPLEMENTATION.md
• Live examples: Crew.ai (#6178), Hermes (#47199), Open Claw (#93609)

Proposed Action

Add cowork-to-code-bridge to the registry under "Local Execution / Code Backends":

• Server name: cowork-to-code-bridge
• Category: Local Execution
• One-line: "MCP server for Claude Code subscription as local execution backend"
• Homepage: https://github.com/abhinaykrupa/cowork-to-code-bridge
