cc-tap

Experimental MCP server that lets Claude Desktop see into and interact with Claude Code Remote Control sessions.

Example: Ask Claude Desktop "what's my Code session working on?" and get a real answer.

Why this exists

Claude Desktop and Claude Code are separate worlds. Both build up rich context on your project, but neither can see what the other is doing. A design idea on Desktop that should drive an implementation in Code, or an implementation detail in Code that the Desktop conversation needs; both require you to copy-paste between windows and re-explain context that already exists.

Claude Code's Remote Control lets you drive a session from another device, but that's still you driving the same session. cc-tap is for the other axis: letting a different agent (Claude Desktop, or another Claude Code instance) read and interact with a running CC session through MCP.

Who is this for

• Developers who use both Claude Desktop and Claude Code
• Anyone who wants to monitor or interact with CC sessions programmatically
• Multi-agent workflows where one Claude instance needs to coordinate with another

Quickstart

pip install cc-tap

Requires an active Claude Code login (claude /login) and Remote Control enabled.

Claude Code

claude mcp add cc-tap -- cc_tap

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "cc-tap": {
      "command": "cc_tap",
      "args": []
    }
  }
}

Tools

How it works

cc-tap reads your Claude Code OAuth credentials (from macOS Keychain or ~/.claude/.credentials.json) and talks to the same API that Claude Code's Remote Control web UI uses. No additional authentication needed.

Sessions are accessed via HTTP polling (~1.5s latency). Messages you send appear in the target CC session as if typed by the user.

Limitations

• Tool approval — the session runtime only picks up approvals via WebSocket (behind Cloudflare bot protection). You can see pending tool requests via send_and_wait, but must approve them in the CC terminal or claude.ai/code web UI.
• Not real-time — uses HTTP polling, not WebSocket streaming. ~1.5s latency.
• Undocumented API — uses internal Anthropic endpoints that may change without notice.
• Local only — reads credentials from the local machine. Can't be deployed as a remote service.

Protocol

See PROTOCOL.md for the reverse-engineered Claude Code Remote session API documentation.
