Instructions

Implementation Reference

• src/index.ts:696-716 (handler)

  The handler function that executes the 'magerun2 sys:check' command using the executeMagerun2Command helper, processes the result, handles errors, and returns formatted text content.

      const command = `magerun2 sys:check`;
      const result = await executeMagerun2Command(command);
  
      if (!result.success) {
        return {
          content: [{
            type: "text",
            text: result.error
          }],
          isError: true
        };
      }
  
      return {
        content: [{
          type: "text",
          text: `System check results:\n\n${result.data}`
        }]
      };
    }
  );

• src/index.ts:690-694 (schema)

  Input/output schema for the sys-check tool: title, description, and empty inputSchema indicating no parameters are required.

  {
    title: "System Check",
    description: "Check Magento 2 system requirements and configuration",
    inputSchema: {}
  },

• src/index.ts:689-717 (registration)

  Registration of the sys-check tool with McpServer using server.registerTool, including name, schema, and handler function.

    "sys-check",
    {
      title: "System Check",
      description: "Check Magento 2 system requirements and configuration",
      inputSchema: {}
    },
    async () => {
      const command = `magerun2 sys:check`;
      const result = await executeMagerun2Command(command);
  
      if (!result.success) {
        return {
          content: [{
            type: "text",
            text: result.error
          }],
          isError: true
        };
      }
  
      return {
        content: [{
          type: "text",
          text: `System check results:\n\n${result.data}`
        }]
      };
    }
  );

• src/index.ts:27-88 (helper)

  Shared utility function used by sys-check (and other tools) to safely execute magerun2 commands, handle timeouts, parse JSON output, and provide Magento-specific error messages.
