Remove reaction from a message
AI agents call remove_reaction to permanently remove resources in Follow Plan MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing a reaction deletes a stored data record (the reaction association) from the SQLite database. Unlike a write/update, removal is a destructive operation that cannot be easily undone. The blast radius is medium since it only affects a reaction on a single message, not critical project data.
From the tool's definition 'Remove reaction from a message' — removal of data is irreversible without an explicit undo mechanism
Attacks that exploit this kind of access
Remove reaction from a message. It is categorised as a Destructive tool in the Follow Plan MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Follow Plan MCP Server MCP server in PolicyLayer and add a rule for remove_reaction: 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 Plan MCP Server. Nothing to install.
remove_reaction 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 remove_reaction 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 remove_reaction. 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.
remove_reaction is provided by the Follow Plan MCP Server MCP server (vibeclasses/follow-plan-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
