WHAT IT DOES

What generate_alt does on Storyblok MCP Server

AI agents use generate_alt 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 generate_alt is rated Medium

The tool likely generates or modifies metadata (alt text) for assets or content, which is reversible and fits the Write category (creates/modifies data). However, confidence is moderate (0.6) because the description is empty, making the exact operation unclear.

From the tool's definition Tool name 'generate_alt' in Storyblok CMS context suggests generating alternative text (alt descriptions), which is a content modification operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs generate_alt safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Storyblok MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For generate_alt, this is the rule to start with:

generate_alt Rate-limited

generate_alt 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.
