Implementation Reference
- src/index.ts:179-190 (handler)The tool handler for 'delete_blob' which parses input arguments using DeleteBlobSchema and delegates to walrusClient.deleteBlob(blobId), returning the result as JSON text.
case 'delete_blob': { const { blobId } = DeleteBlobSchema.parse(args); const result = await walrusClient.deleteBlob(blobId); return { content: [ { type: 'text', text: JSON.stringify(result, null, 2), }, ], }; } - src/index.ts:43-45 (schema)Zod schema for validating the input parameters of the delete_blob tool (requires blobId string).
const DeleteBlobSchema = z.object({ blobId: z.string().describe('The blob ID to delete'), }); - src/index.ts:102-115 (registration)Registration of the 'delete_blob' tool in the list_tools response, including name, description, and input schema.
{ name: 'delete_blob', description: 'Delete a blob from Walrus storage', inputSchema: { type: 'object', properties: { blobId: { type: 'string', description: 'The blob ID to delete', }, }, required: ['blobId'], }, }, - src/walrus-client.ts:161-167 (helper)Implementation of deleteBlob method in WalrusClient class. Currently a stub that always returns failure since Walrus does not support manual blob deletion.
async deleteBlob(blobId: string): Promise<{ success: boolean; message: string }> { // Note: Walrus blobs cannot be deleted once stored - they expire based on their epoch settings return { success: false, message: 'Walrus blobs cannot be manually deleted. They will expire automatically based on their storage epochs.', }; }
