Implementation Reference

• src/index.ts:489-509 (handler)

  The handler function for 'list-file-types' tool. It runs 'rg --type-list --color never', processes the output by stripping ANSI codes, and returns it as text content.

  case "list-file-types": {
    // No colors for type listing
    const command = "rg --type-list --color never";
    
    console.error(`Executing: ${command}`);
    const { stdout, stderr } = await exec(command);
    
    // If there's anything in stderr, log it for debugging
    if (stderr) {
      console.error(`ripgrep stderr: ${stderr}`);
    }
    
    return {
      content: [
        {
          type: "text",
          text: stripAnsiEscapeCodes(stdout) || "Failed to get file types"
        }
      ]
    };
  }

• src/index.ts:169-177 (registration)

  Registration of the 'list-file-types' tool in the ListTools response, including its name, description, and empty input schema (no parameters required).

      inputSchema: {
        type: "object",
        properties: {}
      }
    }
  ]

• src/index.ts:172-177 (schema)

  The input schema for 'list-file-types', which is an empty object indicating no input parameters are needed.

        properties: {}
      }
    }
