  The actual implementation of bucket_exists method in MinioClient class that checks if a bucket exists using the MinIO client's bucket_exists method and returns a dictionary with bucket name and existence status.

  def bucket_exists(self, bucket_name: str) -> dict:
      """Check if a bucket exists.
  
      Args:
          bucket_name: Name of the bucket to check
  
      Returns:
          Dictionary with exists status
      """
      exists = self._client.bucket_exists(bucket_name)
      return {"bucket": bucket_name, "exists": exists}

• src/minio_mcp/server.py:84-97 (registration)

  Tool registration in the TOOLS list that defines the minio_bucket_exists tool with its name, description, and input schema requiring a bucket_name parameter.

  Tool(
      name="minio_bucket_exists",
      description="Check if a bucket exists in MinIO",
      inputSchema={
          "type": "object",
          "properties": {
              "bucket_name": {
                  "type": "string",
                  "description": "Name of the bucket to check",
              },
          },
          "required": ["bucket_name"],
      },
  ),

  Handler in the call_tool function that routes minio_bucket_exists tool calls to the MinioClient's bucket_exists method, passing the bucket_name argument.
