WHAT IT DOES

Parameter	Type	Required	Description
`comment`	string	Yes	New comment text.
`activityId`	string	Yes	Activity ID from getPlan activity array.
`versionTimestamp`	number	Yes	Comment's updated_at as Unix ms for optimistic locking.

Parameters from the server's own tool schema.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs updatePlanComment safely

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

updatePlanComment Rate-limited

updatePlanComment 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.
