WHAT IT DOES

What resume does on Ncp

AI agents invoke resume to trigger actions in Ncp. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why resume is rated High

Resuming a paused job triggers external execution whose effects depend on what the job does. This is an operational action that initiates processing, placing it in the Execute category. Severity is medium because the blast radius depends on the job being resumed, but the description is vague, lowering confidence slightly.

From the tool's definition 'Resume paused job' — triggers execution of a previously paused job/workflow

RECOMMENDED RULE

The rule that runs resume 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 resume, this is the rule to start with:

resume Rate-limited

resume stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about resume

What does the resume tool do? +

Resume paused job. It is categorised as a Execute tool in the Ncp MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on resume? +

Register the Ncp MCP server in PolicyLayer and add a rule for resume: 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 resume? +

resume is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit resume? +

Yes. Add a rate_limit block to the resume 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 resume completely? +

Set action: deny in the PolicyLayer policy for resume. 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 resume? +

resume 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.
