Why apitap_peek needs a policy

This tool retrieves metadata about web resources (accessibility status, bot protection mechanisms, framework detection) via HTTP HEAD requests. HEAD requests have no side effects and do not modify any state. The tool is purely observational/diagnostic. It fits the Read category (queries data, no side effects).

From the tool's definition apitap_peek performs 'HTTP HEAD triage of a URL — checks accessibility, bot protection, framework.' HTTP HEAD is a read-only HTTP method that retrieves only headers without fetching or modifying content, and this tool explicitly performs checks/inspection…

POLICY

How to control apitap_peek

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

policy.json

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

apitap_peek is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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

Questions about apitap_peek

What does the apitap_peek tool do? +

HTTP HEAD triage of a URL — checks accessibility, bot protection, framework. It is categorised as a Read tool in the ApiTap MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on apitap_peek? +

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

What risk level is apitap_peek? +

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

Can I rate-limit apitap_peek? +

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

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

apitap_peek is provided by the ApiTap MCP server (n1byn1kt/apitap). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every ApiTap tool call.

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