• src/mcp_prefect/block.py:10-45 (handler)

  The handler function implementing the 'get_block_types' MCP tool. It uses the Prefect client to fetch block types with optional filters and returns the result as text content.

  @mcp.tool
  async def get_block_types(
      limit: Optional[int] = None,
      offset: Optional[int] = None,
      slug: Optional[str] = None,
  ) -> List[Union[types.TextContent, types.ImageContent, types.EmbeddedResource]]:
      """
      Get a list of block types with optional filtering.
      
      Args:

          offset: Number of block types to skip
          slug: Filter by slug pattern
