  The complete implementation of the deleteSignature tool that removes a cryptographic signature from a CID on Pinata IPFS. It accepts network (public/private) and cid parameters, makes a DELETE request to the Pinata API, and returns a success or error response.

  server.tool(
    "deleteSignature",
    "Remove a signature from a CID",
    {
      network: z
        .enum(["public", "private"])
        .default("public")
        .describe("Whether the file is on public or private IPFS"),
      cid: z.string().describe("The CID to remove the signature from"),
    },
    async ({ network, cid }) => {
      try {
        const url = `https://api.pinata.cloud/v3/files/${network}/signature/${cid}`;
  
        const response = await fetch(url, {
          method: "DELETE",
          headers: getHeaders(),
        });
  
        if (!response.ok) {
          throw new Error(
            `Failed to delete signature: ${response.status} ${response.statusText}`
          );
        }
  
        const data = await response.json();
        return {
          content: [
            {
              type: "text",
              text: `✅ Signature deleted successfully\n\n${JSON.stringify(data, null, 2)}`,
            },
          ],
        };
      } catch (error) {
        return errorResponse(error);
      }
    }
  );
