Implementation Reference

• src/tool_handlers.ts:555-574 (handler)

  The handler function for 'w3_can_blob_rm' that validates input arguments using Zod schema, executes the w3 CLI command 'can blob rm <multihash>', and returns a structured response with success message and stdout.

  const handleW3CanBlobRm: ToolHandler = async (args) => {
    const parsed = Schemas.W3CanBlobRmArgsSchema.safeParse(args);
    if (!parsed.success)
      throw new Error(
        `Invalid arguments for w3_can_blob_rm: ${parsed.error.message}`
      );
    const { multihash } = parsed.data;
    const { stdout } = await runW3Command(`can blob rm ${multihash}`);
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify({
            message: `Blob ${multihash} removed successfully.`,
            output: stdout.trim(),
          }),
        },
      ],
    };
  };

• src/schemas.ts:215-223 (schema)

  Zod schema defining the input parameters for the w3_can_blob_rm tool: requires a 'multihash' string (Base58btc encoded multihash of the blob). Includes description for MCP tool metadata.

  export const W3CanBlobRmArgsSchema = z
    .object({
      multihash: z
        .string()
        .describe("Base58btc encoded multihash of the blob to remove."),
    })
    .describe(
      "Removes a blob from the store by its base58btc encoded multihash."
    );

• src/tool_handlers.ts:964-964 (registration)

  Registration of the 'w3_can_blob_rm' tool in the toolHandlers map, which is used by the MCP server to route CallTool requests to the appropriate handler.

  w3_can_blob_rm: handleW3CanBlobRm,
