Notion MCP Server

Implementation Reference

• src/lib/mcp-server.ts:631-656 (registration)

  Registers the 'get-me' tool with an empty schema. The handler retrieves the bot user information using notionService.retrieveMe(), formats it as JSON text content, and handles errors by returning an error message.

  this.server.tool("get-me", {}, async () => {
    try {
      const result = await this.notionService.retrieveMe();
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify(result, null, 2),
          },
        ],
      };
    } catch (error) {
      console.error("Error in get-me tool:", error);
      return {
        content: [
          {
            type: "text",
            text: `Error: Failed to retrieve bot user - ${
              (error as Error).message
            }`,
          },
        ],
        isError: true,
      };
    }
  });

• src/lib/mcp-server.ts:631-656 (handler)

  The inline async handler function for the 'get-me' tool, which executes the core logic: calls retrieveMe on notionService and returns formatted result or error.

  this.server.tool("get-me", {}, async () => {
    try {
      const result = await this.notionService.retrieveMe();
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify(result, null, 2),
          },
        ],
      };
    } catch (error) {
      console.error("Error in get-me tool:", error);
      return {
        content: [
          {
            type: "text",
            text: `Error: Failed to retrieve bot user - ${
              (error as Error).message
            }`,
          },
        ],
        isError: true,
      };
    }
  });

• src/lib/notion.ts:305-311 (helper)

  Supporting method in NotionService that calls the Notion API client.users.me() to retrieve the current bot user's information.

  async retrieveMe() {
    try {
      return await this.client.users.me({});
    } catch (error) {
      this.handleError(error);
    }
  }
