AI agents invoke onyx_password_strength to trigger processes or run actions in Onyx Mcp. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.

onyx_password_strength can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

What does the onyx_password_strength tool do? +

Score password strength on a 0-100 scale. Returns Shannon entropy (bits), character-class diversity, length, common-pattern detection (sequences, repeats, dictionary-likeness), and a verdict (very_weak / weak / fair / strong / very_strong). Use when an agent generates passwords for accounts it creates, or when validating user-supplied credentials. Stdlib-only — runs locally, never sends the password anywhere. <5ms. (price: $0.001 USDC, tier: metered). It is categorised as a Execute tool in the Onyx Mcp MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on onyx_password_strength? +

Register the Onyx MCP server in PolicyLayer and add a rule for onyx_password_strength: 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 Onyx Mcp. Nothing to install.

What risk level is onyx_password_strength? +

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

Can I rate-limit onyx_password_strength? +

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

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

onyx_password_strength is provided by the Onyx MCP server (https://onyx-actions.onrender.com/mcp/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
