Launch a browser to capture a site\
AI agents invoke apitap_capture to trigger actions in ApiTap. 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.
This tool executes an external browser process and interacts with websites to capture API endpoints. It triggers real external operations (browser launch, network requests to third-party sites) whose effects depend on the target URL argument. This is Execute-level because it runs a browser and performs network-level interactions, not merely reading local data.
From the tool's definition 'Launch a browser to capture a site' — actively launches a browser process and performs capture operations on external websites
Documented attack patterns abuse exactly the kind of access apitap_capture gives an agent:
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_capture:
{
"version": "1",
"default": "deny",
"tools": {
"apitap_capture": {
"limits": [
{
"counter": "apitap_capture_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}apitap_capture 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.

Launch a browser to capture a site\. It is categorised as a Execute tool in the ApiTap MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the ApiTap MCP server in PolicyLayer and add a rule for apitap_capture: 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.
apitap_capture 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 apitap_capture 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 apitap_capture. 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.
apitap_capture 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.
Start from ApiTap, 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.
