get-position

Instructions

Implementation Reference

• src/bot.ts:158-171 (handler)

  Handler function that retrieves the bot's current position (floored coordinates) and returns a formatted text response.

  async (): Promise<McpResponse> => {
    try {
      const position = bot.entity.position;
      const pos = {
        x: Math.floor(position.x),
        y: Math.floor(position.y),
        z: Math.floor(position.z)
      };
  
      return createResponse(`Current position: (${pos.x}, ${pos.y}, ${pos.z})`);
    } catch (error) {
      return createErrorResponse(error as Error);
    }
  }

• src/bot.ts:154-172 (registration)

  Registers the 'get-position' tool on the MCP server with empty input schema and inline handler.

  server.tool(
    "get-position",
    "Get the current position of the bot",
    {},
    async (): Promise<McpResponse> => {
      try {
        const position = bot.entity.position;
        const pos = {
          x: Math.floor(position.x),
          y: Math.floor(position.y),
          z: Math.floor(position.z)
        };
  
        return createResponse(`Current position: (${pos.x}, ${pos.y}, ${pos.z})`);
      } catch (error) {
        return createErrorResponse(error as Error);
      }
    }
  );

• src/bot.ts:140-140 (registration)

  Invocation of registerPositionTools which includes the get-position tool registration.

  registerPositionTools(server, bot);

• src/bot.ts:153-253 (helper)

  Helper function that registers position-related tools, including 'get-position'.

  function registerPositionTools(server: McpServer, bot: any) {
