AI agents use create_space_role to create or update resources in Storyblok MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Storyblok MCP Server environment.

PolicyLayer is an MCP gateway — it sits between your AI agents and Storyblok MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_space_role:
{
"version": "1",
"default": "deny",
"tools": {
"create_space_role": {
"limits": [
{
"counter": "create_space_role_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
