WHAT IT DOES

What TerminalInterrupt does on DutyDeck

AI agents use TerminalInterrupt to create or update resources in DutyDeck, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your DutyDeck environment.

RISK

Why TerminalInterrupt is rated Medium

An AI agent can call TerminalInterrupt faster than any human can review: one bad instruction and it creates or modifies resources in DutyDeck by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs TerminalInterrupt safely

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

TerminalInterrupt Rate-limited

TerminalInterrupt stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect DutyDeck, apply this rule, and every TerminalInterrupt call is checked against it from then on.

FAQ

Questions about TerminalInterrupt

What does the TerminalInterrupt tool do? +

Send Ctrl+C to a running terminal owned by the current Agent session. The terminal remains visible. It is categorised as a Write tool in the DutyDeck MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on TerminalInterrupt? +

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

What risk level is TerminalInterrupt? +

TerminalInterrupt is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit TerminalInterrupt? +

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

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

TerminalInterrupt is provided by the DutyDeck MCP server (taokoplay/DutyDeck). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
