  title: Workato Secure MCP Server Access
  summary: Apply security policies and grant a user group access to an MCP server.
  description: >-
    Locks down a Model Context Protocol server. The workflow confirms the MCP
    server exists, looks up an available identity provider user group, updates
    the server's security policies with rate limits and IP controls, and grants
    the user group access. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI description.
