Class MCP

java.lang.Object
com.codename1.mcp.MCP
public final class MCP extends Object

Public entry point for the Codename One MCP headless API. Invoking a starter here is the enablement; there is no build hint or property to toggle. A single server instance exists per process.

This API is supported by the Codename One JavaSE port, which powers the simulator and the desktop tooling. It is not part of a packaged application build.

Typical usage
// Let a running tool or the simulator accept an attaching agent on a local port:
MCP.startSocketServer(8642);

// Or serve over stdio when a host launches the tool as a subprocess:
MCP.startStdioServer();

// Publish domain tools alongside the automatic UI driving tools:
MCP.addTool(myTool);

  • Method Details

    • setStdioTransportFactory

      public static void setStdioTransportFactory(MCP.StdioTransportFactory factory)
      Registers the platform stdio transport factory. Called by the JavaSE port.

    • setSocketTransportFactory

      public static void setSocketTransportFactory(MCP.SocketTransportFactory factory)
      Registers the platform socket transport factory. Called by the JavaSE port.

    • isStdioSupported

      public static boolean isStdioSupported()
      Whether an stdio transport is available on this platform.

    • isSocketSupported

      public static boolean isSocketSupported()
      Whether a loopback socket transport is available on this platform.

    • getServer

      public static MCPServer getServer()
      Returns the shared server, creating it on first use.

    • isRunning

      public static boolean isRunning()

    • startStdioServer

      public static MCPServer startStdioServer()
      Starts the stdio transport server (the standard MCP local transport). Requires a platform stdio transport factory (registered by the JavaSE port).

    • startSocketServer

      public static MCPServer startSocketServer(int port)
      Starts a loopback socket server so an agent can attach to this running process. Requires a platform socket transport factory (registered by the JavaSE port).

    • stop

      public static void stop()
      Stops the shared server if it is running.

    • addTool

      public static void addTool(Tool tool)
      Registers a developer defined tool with the shared server.

    • setVerbosity

      public static void setVerbosity(MCPVerbosity verbosity)
      Sets how much of the MCP conversation is echoed to the Codename One log so a developer can watch and debug what an agent is doing.

    • getVerbosity

      public static MCPVerbosity getVerbosity()
