Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent.

## About

# cc-tap

[](https://opensource.org/licenses/MIT)
[](https://www.python.org/downloads/)

Experimental MCP server that lets Claude Desktop see into and interact with Claude Code [Remote Control](https://code.claude.com/docs/en/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](https://code.claude.com/docs/en/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

```bash
pip install cc-tap
```

Requires an active Claude Code login (`claude /login`) and [Remote Control](https://code.claude.com/docs/en/remote-control) enabled.

### Claude Code

```bash
claude mcp add cc-tap -- cc_tap
```

### Claude Desktop

Add to `claude_desktop_config.json`:

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

## Tools

| Tool | Description |
|------|-------------|
| `list_sessions` | List all CC sessions (optionally filter by status) |
| `get_session_info` | Get details about a specific session |
| `read_session` | Read recent conversation from a session |
| `get_session_events` | Get raw events, optionally filtered by type |
| `send_message` | Send a message to a CC session (fire and forget) |
| `send_and_wait` | Send a message and wait for the full response |

## 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](https://code.claude.com/docs/en/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](https://github.com/es617/cc-tap/blob/main/PROTOCOL.md) for the reverse-engineered Claude Code Remote session API documentation.

## Development

```bash
git clone https://github.com/es617/cc-tap.git
cd cc-tap
pip install -e ".[dev,test]"
pre-commit install
pytest
```
