validate_security · InSite MCP: Risk & Policy

WHAT IT DOES

What validate_security does on InSite

AI agents invoke validate_security to trigger actions in InSite. 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.

WHY IT NEEDS A POLICY

Why validate_security needs a policy

Vulnerability scanning actively probes and interacts with web pages, sending requests, injecting test payloads, and performing automated reconnaissance. This goes beyond passive reading — it executes active operations against external targets. Misuse could trigger unintended attacks on third-party systems, cause rate-limiting, or violate terms of service.

Verdict

validate_security Rate-limited

validate_security 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches InSite, so you can run agents against it safely.

FAQ

Questions about validate_security

What does the validate_security tool do? +

Security validation and vulnerability scanning for web pages. It is categorised as a Execute tool in the InSite MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on validate_security? +

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

What risk level is validate_security? +

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

Can I rate-limit validate_security? +

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