WHAT IT DOES

What plan_embed_message does on GuildControl MCP

AI agents use plan_embed_message 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 plan_embed_message is rated Medium

RECOMMENDED RULE

The rule that runs plan_embed_message 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 plan_embed_message, this is the rule to start with:

plan_embed_message Rate-limited

plan_embed_message 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.
