Updates a space role's configuration via the Storyblok Management API.
AI agents use update_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.
This tool modifies (writes) space role configurations, which are reversible changes. While role updates could have significant blast radius if an AI agent grants excessive permissions or modifies critical roles, the operation itself is not destructive (roles can be reconfigured), not financial, and not code execution.
From the tool's definition Tool name 'update_space_role' and description 'Updates a space role's configuration' indicate modification of access control settings. This is a reversible write operation that modifies role-based permissions and configurations.
Documented attack patterns abuse exactly the kind of access update_space_role gives an agent:
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 update_space_role:
{
"version": "1",
"default": "deny",
"tools": {
"update_space_role": {
"limits": [
{
"counter": "update_space_role_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_space_role stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Updates a space role's configuration via the Storyblok Management API. It is categorised as a Write tool in the Storyblok MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Storyblok MCP Server MCP server in PolicyLayer and add a rule for update_space_role: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Storyblok MCP Server. Nothing to install.
update_space_role is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_space_role rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for update_space_role. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
update_space_role is provided by the Storyblok MCP Server MCP server (kiran1689/storyblok-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Storyblok MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
