Delete a checkpoint you no longer need.
AI agents call delete_checkpoint to permanently remove resources in Context Travel MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes checkpoint data without recovery mechanism. While the blast radius is limited to context state rather than production data, the irreversible nature of deletion combined with the tool's core function of managing critical context state justifies Destructive classification over Write.
From the tool's definition Tool description explicitly states 'Delete a checkpoint you no longer need' — the action is irreversible deletion of stored state data.
Attacks that exploit this kind of access
Delete a checkpoint you no longer need. It is categorised as a Destructive tool in the Context Travel MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Context Travel MCP server in PolicyLayer and add a rule for delete_checkpoint: 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 Context Travel MCP. Nothing to install.
delete_checkpoint 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 delete_checkpoint 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 delete_checkpoint. 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.
delete_checkpoint is provided by the Context Travel MCP server (simen/mcp-memento). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
