AI agents invoke graudit_scan to trigger actions in SAST 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.
The tool name follows the pattern of other scan tools on this server (e.g., bandit_scan, bearer_scan, brakeman_scan), which are static analysis security testing tools that execute code analysis. Graudit is a known open-source grep-based code auditing tool that runs shell commands to scan source code for vulnerabilities.
From the tool's definition Tool name 'graudit_scan' on a SAST MCP server with sibling tools like bandit_scan, semgrep, brakeman_scan — all security scanning/execution tools
Documented attack patterns abuse exactly the kind of access graudit_scan gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SAST MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for graudit_scan:
{
"version": "1",
"default": "deny",
"tools": {
"graudit_scan": {
"limits": [
{
"counter": "graudit_scan_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}graudit_scan 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.

graudit_scan. It is categorised as a Execute tool in the SAST MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the SAST MCP Server MCP server in PolicyLayer and add a rule for graudit_scan: 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 SAST MCP Server. Nothing to install.
graudit_scan 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 graudit_scan 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 graudit_scan. 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.
graudit_scan is provided by the SAST MCP Server MCP server (sengtocxoen/sast-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from SAST MCP Server, 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.
