WHAT IT DOES

What preview_component_layout does on GuildControl MCP

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

RISK

Why preview_component_layout is rated Medium

An AI agent can call preview_component_layout faster than any human can review: one bad instruction and it creates or modifies resources in GuildControl MCP by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs preview_component_layout safely

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

preview_component_layout Rate-limited

preview_component_layout 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.
