LogAnalyzer MCP Server

Instructions

Implementation Reference

• src/server.ts:406-413 (handler)

  MCP tool handler for 'list_watched_files' that delegates to FileWatcher.listWatchedFiles() and formats the response as MCPToolResult.

  private async handleListWatchedFiles(args: any): Promise<MCPToolResult> {
    const watchedFiles = await this.fileWatcher.listWatchedFiles();
  
    return {
      success: true,
      data: watchedFiles
    };
  }

• src/server.ts:139-142 (schema)

  Input schema definition for the tool (empty object since no parameters required).

  inputSchema: {
    type: 'object',
    properties: {}
  }

• src/server.ts:136-143 (registration)

  Tool registration in the ListToolsRequestSchema handler, including name, description, and input schema.

  {
    name: 'list_watched_files',
    description: 'List all currently monitored log files',
    inputSchema: {
      type: 'object',
      properties: {}
    }
  },

• src/tools/fileWatcher.ts:89-102 (helper)

  Helper method in FileWatcher class that lists all watched files with their status, recent errors count, and last update time.

  async listWatchedFiles(): Promise<FileWatchResult[]> {
    const results: FileWatchResult[] = [];
  
    for (const [filePath, watchedFile] of this.watchers) {
      results.push({
        filePath,
        newErrors: watchedFile.errors.slice(-5), // Last 5 errors
        totalErrors: watchedFile.errors.length,
        lastUpdate: watchedFile.lastUpdate
      });
    }
  
    return results;
  }

• src/server.ts:189-191 (registration)

  Dispatch/registration case in the CallToolRequestSchema switch statement that routes to the handler.

  case 'list_watched_files':
    result = await this.handleListWatchedFiles(args);
    break;
