## MCP tools (6)

### `cc_register_peer` (~128 tokens)

Register Peer

Register a Claude Code session as a named peer on the bridge. Each peer needs a unique peerId, the CC sessionId to resume, the working directory (cwd), and a human-readable label.

Input parameters:

- `cwd` (string, required): Absolute path to the project working directory
- `label` (string, required): Human-readable label, e.g. 'CC_Backend' or 'CC_Frontend'
- `peerId` (string, required): Unique identifier for this peer, e.g. 'backend' or 'frontend'
- `sessionId` (string, required): Claude Code session ID (used with --resume)

### `cc_deregister_peer` (~48 tokens)

Deregister Peer

Remove a previously registered peer from the bridge. The peer will no longer be reachable for messaging.

Input parameters:

- `peerId` (string, required): Peer ID to deregister, e.g. 'backend'

### `cc_send_message` (~110 tokens)

Send Message to Peer

Send a message from one registered peer to another. The message is relayed by resuming the target's Claude Code session via CLI subprocess. Returns the target's response. Auto-recovers if the target's session has changed.

Input parameters:

- `fromPeerId` (string, required): Peer ID of the sender, e.g. 'backend'
- `message` (string, required): The message content to send to the target peer
- `toPeerId` (string, required): Peer ID of the recipient, e.g. 'frontend'

### `cc_list_peers` (~46 tokens)

List Peers

List all currently registered Claude Code peers on the bridge. Returns peer IDs, session IDs, working directories, labels, and flags peers as potentially stale if idle beyond the configured timeout.

### `cc_get_history` (~68 tokens)

Get Message History

Retrieve the message history for the bridge. Optionally filter by a specific peer ID. Returns messages in chronological order, most recent last.

Input parameters:

- `limit` (number): Maximum number of messages to return (default 50)
- `peerId` (string): Optional peer ID to filter history for

### `cc_health_check` (~38 tokens)

Health Check

Diagnose the bridge's operational status. Checks state file accessibility, lock mechanism, and Claude CLI availability. Returns per-check pass/fail with details.
