  title: Workato MCP Server API
  description: >-
    The Workato MCP Server API provides programmatic management of Model
    Context Protocol (MCP) servers that expose Workato API collections as
    tools for AI agents. Use this API to create MCP servers, assign tools,
    configure access policies, and manage user group access. MCP servers
    generate unique authenticated URLs usable by AI development environments
    such as Claude Desktop and Cursor. Rate limit is 60 requests per minute.
