AI agents use select_agent to create or update resources in Pentest Ai — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Pentest Ai environment.
An AI agent can call select_agent faster than any human can review — one bad instruction and it creates or modifies resources in Pentest Ai by the hundred, each call as confident as the last.
Documented attack patterns abuse exactly the kind of access select_agent gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Pentest Ai, and nothing reaches the server without passing your rules. This is the rule we recommend for select_agent:
{
"version": "1",
"default": "deny",
"tools": {
"select_agent": {
"limits": [
{
"counter": "select_agent_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}select_agent stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

select_agent. It is categorised as a Write tool in the Pentest Ai MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Pentest Ai MCP server in PolicyLayer and add a rule for select_agent: 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 Pentest Ai. Nothing to install.
select_agent is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the select_agent 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 select_agent. 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.
select_agent is provided by the Pentest Ai MCP server (0xsteph/pentest-ai). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
