enableMcpServer | SignalWire

Expose this agent’s tools as a Model Context Protocol (MCP) server endpoint. Adds a /mcp route that speaks JSON-RPC 2.0, allowing external MCP clients (Claude Desktop, other agents, etc.) to discover and invoke the agent’s tools.

This method exposes your agent’s tools as an MCP server. To connect your agent to an external MCP server as a client, use addMcpServer().

Parameters

None.

AgentBase — Returns this for method chaining.
