MinIO Storage MCP

Instructions

Implementation Reference

• src/index.ts:611-625 (handler)

  The handler logic for the 'get_bucket_policy' tool. Validates bucketName input with Zod, calls MinIOStorageClient.getBucketPolicy, and formats the policy as a text response in the MCP content.

  case 'get_bucket_policy': {
    const { bucketName } = z.object({
      bucketName: z.string()
    }).parse(args);
    
    const policy = await this.minioClient.getBucketPolicy(bucketName);
    return {
      content: [
        {
          type: 'text',
          text: `存储桶 ${bucketName} 的策略:\n${policy}`
        }
      ]
    };
  }

• src/index.ts:290-300 (registration)

  Registration of the 'get_bucket_policy' tool in the ListTools response, including name, description, and input schema definition.

  {
    name: 'get_bucket_policy',
    description: '获取存储桶策略',
    inputSchema: {
      type: 'object',
      properties: {
        bucketName: { type: 'string', description: '存储桶名称' }
      },
      required: ['bucketName']
    }
  },

• src/minio-client.ts:337-340 (helper)

  Helper method in MinIOStorageClient class that ensures connection and delegates to the underlying MinIO client's getBucketPolicy method.

  async getBucketPolicy(bucketName: string): Promise<string> {
    this.ensureConnected();
    return await this.client!.getBucketPolicy(bucketName);
  }
