    name: The name of the workflow to delete

Returns:
    dict: Status of the operation

Implementation Reference

• src/server.py:333-364 (handler)

  Primary MCP tool handler for 'delete_workflow'. Sanitizes the workflow name, resolves the file path, checks existence, deletes the file, and returns status.

  @mcp.tool()
  def delete_workflow(name: str) -> dict:
      """
      Delete a workflow script.
      
      Args:
          name: The name of the workflow to delete
      
      Returns:
          dict: Status of the operation
      """
      try:
          workflow_path = get_workflow_path(name)
          
          if not workflow_path.exists():

                  "status": "error",
                  "message": f"Workflow '{name}' not found"
              }

• src/server.py:29-33 (helper)

  Helper function used by delete_workflow to compute the sanitized file path in the workflows directory.

  def get_workflow_path(name: str) -> Path:
      """Get the full path for a workflow file."""
      # Sanitize the name to prevent directory traversal
      safe_name = "".join(c for c in name if c.isalnum() or c in "_-").lower()
      return Path(WORKFLOWS_DIR) / f"{safe_name}.py"

• src/mcp_http_server.py:170-182 (schema)

  Explicit JSON input schema for the delete_workflow tool, defining the required 'name' parameter.
