Implementation Reference

• src/index.ts:32-54 (handler)

  The main handler function for the "request_baike" tool. It takes a Baidu Baike URL, fetches discussions using BaikeClient, and returns the JSON-formatted discussions as text content or an error message.

  async ({ url }: { url: string }) => {
    try {
      const discussions = await baikeClient.getDiscussions(url);
      
      return {
        content: [
          { 
            type: "text", 
            text: JSON.stringify(discussions, null, 2)
          }
        ]
      };
    } catch (error) {
      const errorMessage = error instanceof Error 
        ? error.message 
        : "获取百科讨论时发生未知错误";
      
      return {
        content: [{ type: "text", text: errorMessage }],
        isError: true
      };
    }
  }

• src/index.ts:31-31 (schema)

  Input schema definition for the "request_baike" tool using Zod, requiring a single 'url' parameter of type string.

  { url: z.string().describe("百度百科URL，例如：https://baike.baidu.com/item/DeepSeek") },

• src/index.ts:29-55 (registration)

  MCP server tool registration for "request_baike", including the tool name, input schema, and handler function.

  server.tool(
    "request_baike",
    { url: z.string().describe("百度百科URL，例如：https://baike.baidu.com/item/DeepSeek") },
    async ({ url }: { url: string }) => {
      try {
        const discussions = await baikeClient.getDiscussions(url);
        
        return {
          content: [
            { 
              type: "text", 
              text: JSON.stringify(discussions, null, 2)
            }
          ]
        };
      } catch (error) {
        const errorMessage = error instanceof Error 
          ? error.message 
          : "获取百科讨论时发生未知错误";
        
        return {
          content: [{ type: "text", text: errorMessage }],
          isError: true
        };
      }
    }
  );

• src/baike-client.ts:170-191 (helper)

  BaikeClient.getDiscussions helper method: parses URL to lemmaId, makes API request to fetch Baike discussions, handles errors.

  async getDiscussions(lemmaIdOrUrl: string): Promise<BaikeDiscussionResponse> {
    const lemmaId = this.parseLemmaIdOrUrl(lemmaIdOrUrl);
    
    try {
      const response = await axios.get<BaikeDiscussionResponse>(
        `${this.apiBaseUrl}${this.discussionApiPath}?lemmaId=${lemmaId}`,
        {
          headers: {
            "Content-Type": "application/json",
            cookie: this.cookie,
          },
        }
      );
      
      return response.data;
    } catch (error: unknown) {
      if (axios.isAxiosError(error) && error.response) {
        throw new Error(`百度百科API错误: ${error.response.status} - ${JSON.stringify(error.response.data)}`);
      }
      throw error;
    }
  }
