MCPServerOptions

org.llm4s.mcp.MCPServerOptions

case class MCPServerOptions(port: Int, path: String, name: String, version: String, apiKey: Option[String], host: String)

Configuration options for the MCPServer.

Value parameters

apiKey: Optional API key for Bearer-token authentication. When set, every request must include Authorization: Bearer <key>. Configuring an API key removes the development-only security warning and allows binding to non-localhost interfaces via host.
host: Network interface to bind to (default "127.0.0.1"). Change to "0.0.0.0" (or a specific IP) only when apiKey is set; start() refuses to bind a non-loopback host without an apiKey.
name: Server name reported during MCP initialization.
path: Base path for MCP endpoints (e.g. "/mcp").
port: Port to bind to. Use 0 for a random available port.
version: Server version reported during MCP initialization.
