WHAT IT DOES

What update_access_token does on Storyblok MCP Server

AI agents use update_access_token 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.

RISK

Why update_access_token is rated Medium

Updating access tokens modifies authentication credentials reversibly but with high blast radius. This is a Write operation (modification) rather than Read (it actively changes tokens, not just retrieves them), not Execute (doesn't run arbitrary code), and not Destructive (tokens can be regenerated). However, compromised token management could grant unauthorized access to the entire CMS, making this high severity.

From the tool's definition Tool name 'update_access_token' indicates modification of authentication credentials. Storyblok context shows this is a CMS access control mechanism.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_access_token safely

update_access_token Rate-limited

update_access_token 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.
