Workflows MCP Server

Instructions

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(): return { "status": "error", "message": f"Workflow '{name}' not found" } workflow_path.unlink() return { "status": "success", "message": f"Workflow '{name}' deleted successfully" } except Exception as e: return { "status": "error", "message": f"Failed to delete workflow: {str(e)}" }
• 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.
  { "name": "delete_workflow", "description": "Delete a workflow script.", "inputSchema": { "type": "object", "properties": { "name": { "type": "string", "description": "The name of the workflow to delete" } }, "required": ["name"] }
• src/mcp_http_server.py:358-375 (handler)

  HTTP MCP server handler for delete_workflow tool call.
  def tool_delete_workflow(arguments: dict) -> dict: """Delete a workflow.""" try: name = arguments.get("name") if not name: return {"error": "Workflow name is required"} workflow_path = get_workflow_path(name) if not workflow_path.exists(): return {"error": f"Workflow '{name}' not found"} workflow_path.unlink() return {"status": "success", "message": f"Workflow '{name}' deleted successfully"} except Exception as e: return {"error": str(e)}
• src/mcp_http_server.py:384-384 (registration)

  Registration of the delete_workflow handler in the TOOL_HANDLERS dictionary.
