Implementation Reference
- src/claude_ipc_server.py:1084-1105 (handler)The handler for the 'register' tool in the MCP call_tool function. It computes an auth token if a shared secret is set, sends a registration request to the internal MessageBroker via BrokerClient, stores the returned session token globally for subsequent tool calls, and returns the broker's response.
# Calculate auth token instance_id = arguments["instance_id"] shared_secret = os.environ.get("IPC_SHARED_SECRET", "") auth_token = "" if shared_secret: import hashlib auth_token = hashlib.sha256(f"{instance_id}:{shared_secret}".encode()).hexdigest() response = BrokerClient.send_request({ "action": "register", "instance_id": instance_id, "auth_token": auth_token }) # Store session token for this MCP instance if response.get("status") == "ok" and response.get("session_token"): # Store in a global variable for this MCP session global current_session_token, current_instance_id current_session_token = response["session_token"] current_instance_id = instance_id return [TextContent(type="text", text=json.dumps(response, indent=2))] - src/claude_ipc_server.py:909-922 (schema)The JSON schema definition for the 'register' tool's input parameters, specifying that 'instance_id' is a required string.
