MinIO Storage MCP

Instructions

Implementation Reference

• src/index.ts:452-467 (handler)

  Handler for the 'delete_object' tool in the MCP server. Validates input using Zod schema, calls the MinIO client's deleteObject method, and returns a success message.

  case 'delete_object': {
    const { bucketName, objectName } = z.object({
      bucketName: z.string(),
      objectName: z.string()
    }).parse(args);
    
    await this.minioClient.deleteObject(bucketName, objectName);
    return {
      content: [
        {
          type: 'text',
          text: `成功删除对象: ${bucketName}/${objectName}`
        }
      ]
    };
  }

• src/index.ts:165-172 (schema)

  JSON input schema for the 'delete_object' tool, defining required bucketName and objectName parameters.

  inputSchema: {
    type: 'object',
    properties: {
      bucketName: { type: 'string', description: '存储桶名称' },
      objectName: { type: 'string', description: '对象名称' }
    },
    required: ['bucketName', 'objectName']
  }

• src/index.ts:162-173 (registration)

  Registration of the 'delete_object' tool in the list_tools response, including name, description, and schema.

  {
    name: 'delete_object',
    description: '删除存储桶中的对象',
    inputSchema: {
      type: 'object',
      properties: {
        bucketName: { type: 'string', description: '存储桶名称' },
        objectName: { type: 'string', description: '对象名称' }
      },
      required: ['bucketName', 'objectName']
    }
  },

• src/minio-client.ts:152-155 (helper)

  Helper method in MinIOStorageClient that ensures connection and calls MinIO client's removeObject to delete the specified object.

  async deleteObject(bucketName: string, objectName: string): Promise<void> {
    this.ensureConnected();
    await this.client!.removeObject(bucketName, objectName);
  }
