WHAT IT DOES

What plan_message_pin does on GuildControl MCP

AI agents use plan_message_pin 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_message_pin is rated Medium

An AI agent can call plan_message_pin 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.

RECOMMENDED RULE

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

plan_message_pin Rate-limited

plan_message_pin 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.

Register the GuildControl MCP server in PolicyLayer and add a rule for plan_message_pin: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches GuildControl MCP. Nothing to install.

What risk level is plan_message_pin? +

plan_message_pin is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit plan_message_pin? +

How do I block plan_message_pin completely? +
