sql_injection_check
AI agents invoke sql_injection_check to trigger actions in CyberMCP. 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 is part of a security testing MCP server focused on injection attacks. SQL injection checks typically involve sending crafted payloads to target systems to probe for vulnerabilities, which constitutes executing external operations against APIs/databases.
From the tool's definition Tool name 'sql_injection_check' on a server explicitly designed for 'testing backend APIs for security vulnerabilities like authentication bypass, injection attacks, and data leakage'
Documented attack patterns abuse exactly the kind of access sql_injection_check gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and CyberMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for sql_injection_check:
{
"version": "1",
"default": "deny",
"tools": {
"sql_injection_check": {
"limits": [
{
"counter": "sql_injection_check_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}sql_injection_check 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.
Free to start. No card required.
sql_injection_check. It is categorised as a Execute tool in the CyberMCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Cyber MCP server in PolicyLayer and add a rule for sql_injection_check: 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 CyberMCP. Nothing to install.
sql_injection_check 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 sql_injection_check 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 sql_injection_check. 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.
sql_injection_check is provided by the Cyber MCP server (ricauts/cybermcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from CyberMCP, 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.
