Goal Story MCP Server

Instructions

Implementation Reference

• src/index.ts:151-163 (handler)

  The handler function that performs a GET request to the GoalStory API's /about endpoint using the doRequest helper and returns the API response formatted as text content.

  async (args) => {
    const url = `${GOALSTORY_API_BASE_URL}/about`;
    const result = await doRequest(url, "GET");
    return {
      content: [
        {
          type: "text",
          text: `About data:\n${JSON.stringify(result, null, 2)}`,
        },
      ],
      isError: false,
    };
  },

• src/index.ts:147-164 (registration)

  Registers the "goalstory_about" tool with the MCP server, specifying name, description, input schema shape, and the handler function.

  server.tool(
    ABOUT_GOALSTORYING_TOOL.name,
    ABOUT_GOALSTORYING_TOOL.description,
    ABOUT_GOALSTORYING_TOOL.inputSchema.shape,
    async (args) => {
      const url = `${GOALSTORY_API_BASE_URL}/about`;
      const result = await doRequest(url, "GET");
      return {
        content: [
          {
            type: "text",
            text: `About data:\n${JSON.stringify(result, null, 2)}`,
          },
        ],
        isError: false,
      };
    },
  );

• src/tools.ts:6-14 (schema)

  Defines the schema and metadata for the "goalstory_about" tool, including name, description, and empty Zod input schema (no parameters required).

  /**
   * GET /about
   */
  export const ABOUT_GOALSTORYING_TOOL = {
    name: "goalstory_about",
    description:
      "Retrieve information about Goal Story's philosophy and the power of story-driven goal achievement. Use this to help users understand the unique approach of Goal Storying.",
    inputSchema: z.object({}),
  };

• src/types.ts:3-3 (schema)

  TypeScript interface defining the empty input type for the goalstory_about tool.

  export interface GoalstoryAboutInput {}

• src/index.ts:62-122 (helper)

  Generic HTTP request utility function used by the tool handler to make authenticated API calls to the GoalStory backend.

  async function doRequest<T = any>(
    url: string,
    method: string,
    body?: unknown,
  ): Promise<T> {
    console.error("Making request to:", url);
    console.error("Method:", method);
    console.error("Body:", body ? JSON.stringify(body) : "none");
  
    try {
      const response = await axios({
        url,
        method,
        headers: {
          "Content-Type": "application/json",
          Authorization: `Bearer ${GOALSTORY_API_TOKEN}`,
        },
        data: body,
        timeout: 10000, // 10 second timeout
        validateStatus: function (status) {
          return status >= 200 && status < 500; // Accept all status codes less than 500
        },
      });
      console.error("Response received:", response.status);
      return response.data as T;
    } catch (err) {
      console.error("Request failed with error:", err);
  
      if (axios.isAxiosError(err)) {
        if (err.code === "ECONNABORTED") {
          throw new Error(
            `Request timed out after 10 seconds. URL: ${url}, Method: ${method}`,
          );
        }
        if (err.response) {
          // The request was made and the server responded with a status code
          // that falls out of the range of 2xx
          throw new Error(
            `HTTP Error ${
              err.response.status
            }. URL: ${url}, Method: ${method}, Body: ${JSON.stringify(
              body,
            )}. Error text: ${JSON.stringify(err.response.data)}`,
          );
        } else if (err.request) {
          // The request was made but no response was received
          throw new Error(
            `No response received from server. URL: ${url}, Method: ${method}`,
          );
        } else {
          // Something happened in setting up the request that triggered an Error
          throw new Error(`Request setup failed: ${err.message}`);
        }
      } else {
        // Something else happened
        throw new Error(
          `Unexpected error: ${err instanceof Error ? err.message : String(err)}`,
        );
      }
    }
  }
