Execute a read-only OpenROAD command (report_*, get_*, check_*, sta, help, etc.).
AI agents invoke interactive_openroad_query to trigger actions in Openroad. 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.
The tool executes commands within a live OpenROAD interactive session. While described as read-only, it runs arbitrary command strings against a persistent session, meaning a miscreant or confused agent could pass non-read-only commands. The blast radius is high because OpenROAD sessions control EDA (chip design) flows; corrupting or leaking design state could have serious consequences.
From the tool's definition 'Execute a read-only OpenROAD command' — the tool runs commands inside an OpenROAD session. Despite the 'read-only' intent, it accepts arbitrary command strings matching patterns like 'report_*, get_*, check_*, sta, help, etc.' with no hard enforcement of…
Documented attack patterns abuse exactly the kind of access interactive_openroad_query gives an agent:
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 interactive_openroad_query:
{
"version": "1",
"default": "deny",
"tools": {
"interactive_openroad_query": {
"limits": [
{
"counter": "interactive_openroad_query_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}interactive_openroad_query 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.

Execute a read-only OpenROAD command (report_*, get_*, check_*, sta, help, etc.). It is categorised as a Execute tool in the Openroad MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Openroad MCP server in PolicyLayer and add a rule for interactive_openroad_query: 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.
interactive_openroad_query is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the interactive_openroad_query 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 interactive_openroad_query. 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.
interactive_openroad_query 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.
Start from Openroad, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
