Implementation Reference

• src/index.ts:108-141 (registration)

  Registration of the 'get_system_info' tool using this.server.tool, including the inline handler function.

  this.server.tool(
  	{
  		name: 'get_system_info',
  		description: 'Get WSL system information',
  		annotations: {
  			readOnlyHint: true,
  		},
  	},
  	async () => {
  		try {
  			const result = await this.command_executor.execute_command(
  				'uname -a && lsb_release -a 2>/dev/null || cat /etc/os-release',
  			);
  			return {
  				content: [
  					{
  						type: 'text' as const,
  						text: this.format_output(result),
  					},
  				],
  			};
  		} catch (error) {
  			return {
  				content: [
  					{
  						type: 'text' as const,
  						text: `Error: ${error instanceof Error ? error.message : String(error)}`,
  					},
  				],
  				isError: true,
  			};
  		}
  	},
  );

• src/index.ts:116-140 (handler)

  The handler function for get_system_info, which executes WSL system info commands (uname, lsb_release or os-release), formats the output using format_output, and returns as text content or error.

  async () => {
  	try {
  		const result = await this.command_executor.execute_command(
  			'uname -a && lsb_release -a 2>/dev/null || cat /etc/os-release',
  		);
  		return {
  			content: [
  				{
  					type: 'text' as const,
  					text: this.format_output(result),
  				},
  			],
  		};
  	} catch (error) {
  		return {
  			content: [
  				{
  					type: 'text' as const,
  					text: `Error: ${error instanceof Error ? error.message : String(error)}`,
  				},
  			],
  			isError: true,
  		};
  	}
  },
