• src/index.ts:763-794 (handler)

  getGroup tool registration and handler - retrieves detailed information about a specific group by its ID from the Pinata API

  server.tool(
    "getGroup",
    "Retrieve detailed information about a specific group by its ID",
    {
      network: z
        .enum(["public", "private"])
        .default("public")
        .describe("Whether the group is in public or private IPFS"),
      id: z.string().describe("The unique ID of the group to retrieve"),
    },
    async ({ network, id }) => {
      try {
        const url = `https://api.pinata.cloud/v3/groups/${network}/${id}`;
  
        const response = await fetch(url, {
          method: "GET",
          headers: getHeaders(),
        });
  
        if (!response.ok) {
          throw new Error(
            `Failed to get group: ${response.status} ${response.statusText}`
          );
        }
  
        const data = await response.json();
        return successResponse(data);
      } catch (error) {
        return errorResponse(error);
      }
    }
  );

• src/index.ts:100-108 (helper)

  getHeaders helper function - generates authorization headers with the PINATA_JWT token for API requests

  const getHeaders = () => {
    if (!PINATA_JWT) {
      throw new Error("PINATA_JWT environment variable is not set");
    }
    return {
      Authorization: `Bearer ${PINATA_JWT}`,
      "Content-Type": "application/json",
    };
  };

• src/index.ts:111-119 (helper)

  errorResponse helper function - returns a standardized error response format for tool failures

  const errorResponse = (error: unknown) => ({
    content: [
      {
        type: "text" as const,
        text: `Error: ${error instanceof Error ? error.message : String(error)}`,
      },
    ],
    isError: true,
  });

• src/index.ts:122-124 (helper)

  successResponse helper function - returns a standardized success response with JSON-formatted data

  const successResponse = (data: unknown) => ({
    content: [{ type: "text" as const, text: JSON.stringify(data, null, 2) }],
  });
