Implementation Reference

• server.js:258-281 (handler)

  The readFile method that implements the tool logic - reads a file from the working directory and returns its contents with formatting

  async readFile(filePath) {
    try {
      const fullPath = path.join(this.workingDir, filePath);
      const content = await fs.readFile(fullPath, 'utf8');
      
      return {
        content: [
          {
            type: "text",
            text: `Contents of ${filePath}:\n\n\`\`\`\n${content}\n\`\`\``
          }
        ]
      };
    } catch (error) {
      return {
        content: [
          {
            type: "text",
            text: `Error reading file: ${error.message}`
          }
        ]
      };
    }
  }

• server.js:93-106 (schema)

  Tool schema definition for read_file - defines the name, description, and inputSchema with file_path parameter

  {
    name: "read_file",
    description: "Read contents of a file",
    inputSchema: {
      type: "object",
      properties: {
        file_path: {
          type: "string",
          description: "Path to the file to read"
        }
      },
      required: ["file_path"]
    }
  },

• server.js:144-145 (registration)

  Tool routing in CallToolRequestSchema handler - routes 'read_file' requests to the readFile method

  case 'read_file':
    return await this.readFile(args.file_path);
