Delete a reaction from an item
AI agents call deleteReaction to permanently remove resources in Follow Up Boss MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The deleteReaction tool performs an irreversible deletion operation on CRM data (reactions). Once deleted, the reaction cannot be recovered without manual intervention or backups. This matches the Destructive category definition: 'irreversibly deletes or overwrites data, or actions that cannot be undone (delete, drop, purge, force-push)'.
From the tool's definition Tool name explicitly uses 'delete' and description states 'Delete a reaction from an item', indicating irreversible removal of data.

Register the Follow Up Boss MCP Server MCP server in PolicyLayer and add a rule for deleteReaction: 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 Follow Up Boss MCP Server. Nothing to install.
deleteReaction is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the deleteReaction rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for deleteReaction. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
