THE RISK

Critical Risk

Why terminate_interactive_session needs a policy

Terminating a session is irreversible — the running session, its state, and any unsaved work within it are permanently destroyed. This cannot be undone, placing it in the Destructive category. Severity is high because an AI agent misusing this tool could kill active chip design sessions, losing significant computational work and state.

POLICY

How to control terminate_interactive_session

PolicyLayer is an MCP gateway — it sits between your AI agents and Openroad, and nothing reaches the server without passing your rules. This is the rule we recommend for terminate_interactive_session:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "terminate_interactive_session"
  ]
}

terminate_interactive_session disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Openroad — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about terminate_interactive_session

What does the terminate_interactive_session tool do? +

Terminate an interactive OpenROAD session. It is categorised as a Destructive tool in the Openroad 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 terminate_interactive_session? +

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

What risk level is terminate_interactive_session? +

terminate_interactive_session 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 terminate_interactive_session? +

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

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

terminate_interactive_session is provided by the Openroad MCP server (the-openroad-project/openroad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Openroad tool call.

Start from Openroad, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
