What cleanup_resources does on Math MCP Server
AI agents call cleanup_resources to permanently remove resources in Math MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why cleanup_resources is rated Critical
The tool explicitly deletes files, which is an irreversible destructive action. It targets output files and temporary directories, potentially wiping multiple generated artifacts. The high severity reflects the blast radius — misuse could delete all output files from a session. Confidence is high because the description clearly states 'Deletes files'.

Attacks that exploit this kind of access
The rule that runs cleanup_resources safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Math MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For cleanup_resources, this is the rule to start with:
cleanup_resources is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Math MCP Server, apply this rule, and every cleanup_resources call is checked against it from then on.
Questions about cleanup_resources
Brief description: Deletes files generated in OUTPUT_PATH (or default temporary directory) and performs basic resource cleanup. Call only when the user explicitly indicates deletion of temporary or output files. It is categorised as a Destructive tool in the Math MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Math MCP Server MCP server in PolicyLayer and add a rule for cleanup_resources: 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 Math MCP Server. Nothing to install.
cleanup_resources 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 cleanup_resources 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 cleanup_resources. 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.
cleanup_resources is provided by the Math MCP Server MCP server (111-test-111/math-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
