WHAT IT DOES

What probe does on Qverisai

AI agents call probe to retrieve information from Qverisai without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why probe is rated Low

Tool retrieves quote information without executing financial transactions or side effects.

From the tool's definition validate parameters, zero-cost quote, preflight

RECOMMENDED RULE

The rule that runs probe safely

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

probe Allowed

probe is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "probe": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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

FAQ

Questions about probe

What does the probe tool do? +

Optionally validate parameters or obtain a zero-cost quote when inputs are uncertain, a current quote is needed for a budget decision, or preflight is explicitly requested. It is categorised as a Read tool in the Qverisai MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on probe? +

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

What risk level is probe? +

probe is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit probe? +

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

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

probe is provided by the Qverisai MCP server (https://mcp.qveris.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
