AI agents invoke send_request to trigger actions in Burp Mcp Plus. 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.
Given the Burp Suite context, 'send_request' almost certainly sends an HTTP request to an external target, which constitutes triggering an external operation. This is Execute-level as the effects depend on the request arguments (target, method, payload).

Documented attack patterns abuse exactly the kind of access send_request gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Burp Mcp Plus, and nothing reaches the server without passing your rules. This is the rule we recommend for send_request:
{
"version": "1",
"default": "deny",
"tools": {
"send_request": {
"limits": [
{
"counter": "send_request_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}send_request 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.

send_request. It is categorised as a Execute tool in the Burp Mcp Plus MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Burp Mcp Plus MCP server in PolicyLayer and add a rule for send_request: 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 Burp Mcp Plus. Nothing to install.
send_request 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 send_request 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 send_request. 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.
send_request is provided by the Burp Mcp Plus MCP server (titaniumtushar/burp-mcp-plus). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Burp Mcp Plus, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
