MinIO Storage MCP

Instructions

Implementation Reference

• src/index.ts:594-609 (handler)

  MCP tool handler for 'set_bucket_policy': validates input parameters using Zod, calls MinIOStorageClient.setBucketPolicy, and returns a success text response.

  case 'set_bucket_policy': {
    const { bucketName, policy } = z.object({
      bucketName: z.string(),
      policy: z.string()
    }).parse(args);
    
    await this.minioClient.setBucketPolicy(bucketName, policy);
    return {
      content: [
        {
          type: 'text',
          text: `成功设置存储桶 ${bucketName} 的策略`
        }
      ]
    };
  }

• src/index.ts:278-289 (registration)

  Tool registration in list_tools response, including name, description, and input schema definition.

  {
    name: 'set_bucket_policy',
    description: '设置存储桶策略',
    inputSchema: {
      type: 'object',
      properties: {
        bucketName: { type: 'string', description: '存储桶名称' },
        policy: { type: 'string', description: 'JSON格式的策略' }
      },
      required: ['bucketName', 'policy']
    }
  },

• src/index.ts:595-598 (schema)

  Zod schema validation for input arguments in the handler.

  const { bucketName, policy } = z.object({
    bucketName: z.string(),
    policy: z.string()
  }).parse(args);

• src/minio-client.ts:329-332 (helper)

  MinIOStorageClient helper method that implements setBucketPolicy by delegating to the underlying Minio Client SDK.

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