publish-release · MCP Storyblok Server MCP: Risk & Policy

WHAT IT DOES

What publish-release does on MCP Storyblok Server

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

WHY IT NEEDS A POLICY

Why publish-release needs a policy

Publishing a release is a Write operation because it creates or modifies data reversibly. While it changes the published state of content, it does not irreversibly delete data (ruling out Destructive) nor does it execute arbitrary code (ruling out Execute).

From the tool's definition 'Publishes a release' - the tool modifies the state of a release by pushing it to live/published status, which is a state-changing operation that affects content visibility across the CMS.

publish-release Rate-limited

publish-release 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.
