LogAnalyzer MCP Server

Instructions

Implementation Reference

• src/server.ts:388-404 (handler)

  The main MCP tool handler for 'stop_watching'. Validates the filePath argument, calls FileWatcher.stopWatching(), and returns a success response with confirmation message.

  private async handleStopWatching(args: any): Promise<MCPToolResult> {
    const { filePath } = args;
  
    if (!filePath || typeof filePath !== 'string') {
      throw new Error('filePath is required and must be a string');
    }
  
    await this.fileWatcher.stopWatching(filePath);
  
    return {
      success: true,
      data: {
        message: `Stopped watching ${filePath}`,
        filePath
      }
    };
  }

• src/server.ts:122-135 (registration)

  Tool registration in ListTools handler, including name, description, and input schema definition requiring 'filePath'.

  {
    name: 'stop_watching',
    description: 'Stop monitoring a specific log file',
    inputSchema: {
      type: 'object',
      properties: {
        filePath: {
          type: 'string',
          description: 'Path to the log file to stop monitoring'
        }
      },
      required: ['filePath']
    }
  },

• src/tools/fileWatcher.ts:79-87 (helper)

  Core helper method in FileWatcher class that closes the chokidar file watcher for the specified path and removes it from the internal tracking map.

  async stopWatching(filePath: string): Promise<void> {
    const watchedFile = this.watchers.get(filePath);
    if (!watchedFile) {
      throw new Error(`File ${filePath} is not being watched`);
    }
  
    await watchedFile.watcher.close();
    this.watchers.delete(filePath);
  }
