WHAT IT DOES

What delete does on Ncp

AI agents call delete to permanently remove resources in Ncp, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete is rated Critical

This tool performs an irreversible deletion operation on a scheduled job. Once deleted, the job configuration and state cannot be recovered without external backup/restoration procedures. This is a destructive action that cannot be undone through normal tool operations, fitting the Destructive category.

From the tool's definition Tool name 'delete' combined with description 'Delete scheduled job' indicates irreversible removal of a scheduled job resource.

RECOMMENDED RULE

The rule that runs delete safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ncp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete, this is the rule to start with:

delete Hidden

delete 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 Ncp, apply this rule, and every delete call is checked against it from then on.

FAQ

Questions about delete

What does the delete tool do? +

Delete scheduled job. It is categorised as a Destructive tool in the Ncp MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on delete? +

Register the Ncp MCP server in PolicyLayer and add a rule for delete: 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 Ncp. Nothing to install.

What risk level is delete? +

delete is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit delete? +

Yes. Add a rate_limit block to the delete 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.

How do I block delete completely? +

Set action: deny in the PolicyLayer policy for delete. 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.

What MCP server provides delete? +

delete is provided by the Ncp MCP server (@portel/ncp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
