scan_url · SQL Injection MCP Server MCP: Risk & Policy

WHAT IT DOES

What scan_url does on SQL Injection MCP Server

AI agents invoke scan_url to trigger actions in SQL Injection MCP Server. 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 scan_url needs a policy

Based on the server context, scan_url likely actively probes a target URL with SQL injection payloads, which constitutes executing external operations against a web application. The sibling tools (scan_get_parameter, scan_post_parameter, scan_urls_batch) confirm this is an active scanning tool.

From the tool's definition Tool name 'scan_url' on a server explicitly designed for 'identifying SQL injection vulnerabilities' using 'error-based, time-based, and union-based scanning' with 'WAF bypass strategies'

Verdict

scan_url Rate-limited

scan_url 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.
