Remove a premise by index from the current session.
AI agents call remove_premise to permanently remove resources in FOL Prover MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing a premise from a session deletes data that may not be easily recoverable depending on session state. The operation is a targeted deletion (remove by index) rather than a modification, making it Destructive. Severity is medium since it affects session-local theorem proving state rather than persistent external data.

Attacks that exploit this kind of access
Remove a premise by index from the current session. It is categorised as a Destructive tool in the FOL Prover MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the FOL Prover MCP Server MCP server in PolicyLayer and add a rule for remove_premise: 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 FOL Prover MCP Server. Nothing to install.
remove_premise 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_premise 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_premise. 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_premise is provided by the FOL Prover MCP Server MCP server (newjerseystyle/folprover-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
