Implementation Reference

• server.js:820-849 (handler)

  The handler logic for executing the 'clear_cache' tool. It processes the input 'type' parameter and clears the appropriate caches: document cache via CacheManager.clear(), index via DocumentIndexer.clear(), or all including NodeCache.flushAll().

  case "clear_cache": {
    const { type = "all" } = args;
  
    switch (type) {
      case "document":
        await cacheManager.clear();
        var clearedMessage = "已清空文档缓存";
        break;
      case "index":
        documentIndexer.clear();
        var clearedMessage = "已清空全文索引";
        break;
      case "all":
      default:
        await cacheManager.clear();
        documentIndexer.clear();
        documentCache.flushAll();
        var clearedMessage = "已清空所有缓存（文档缓存、全文索引、内存缓存）";
        break;
    }
  
    return {
      content: [
        {
          type: "text",
          text: clearedMessage
        }
      ]
    };
  }

• server.js:550-564 (registration)

  Registration of the 'clear_cache' tool in the ListToolsRequestHandler response, including name, description, and input schema.

  {
    name: "clear_cache",
    description: "清空所有缓存",
    inputSchema: {
      type: "object",
      properties: {
        type: {
          type: "string",
          description: "清除类型：all, document, index",
          enum: ["all", "document", "index"],
          default: "all"
        }
      }
    }
  },

• server.js:553-562 (schema)

  Input schema definition for the 'clear_cache' tool, specifying the optional 'type' parameter.

  inputSchema: {
    type: "object",
    properties: {
      type: {
        type: "string",
        description: "清除类型：all, document, index",
        enum: ["all", "document", "index"],
        default: "all"
      }
    }

• server.js:419-428 (helper)

  CacheManager.clear() method used by the clear_cache handler to clear document caches.

  async clear() {
    await this.initialize();
    const files = await fs.readdir(this.cacheDir);
    for (const file of files) {
      if (file !== 'metadata.json') {
        await fs.remove(path.join(this.cacheDir, file));
      }
    }
    await fs.writeJson(this.metadataFile, {});
  }

• server.js:133-137 (helper)

  DocumentIndexer.clear() method used by the clear_cache handler to clear the full-text index.

  clear() {
    this.index.clear();
    this.documents.clear();
    this.lastUpdated = Date.now();
  }
