What semgrep_scan does on Kali Security MCP
AI agents invoke semgrep_scan to trigger actions in Kali Security MCP. 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 semgrep_scan is rated High
Semgrep is a static analysis tool that scans code for vulnerabilities and security issues. On a Kali Linux security/pentesting server alongside active attack tools, this likely executes semgrep against target code or systems. Even as a read-oriented scan, it executes external tooling with potential side effects.
From the tool's definition Tool name 'semgrep_scan' on a Kali Linux penetration testing server with sibling tools like 'ad_full_attack', 'adaptive_network_penetration', and 'adaptive_sqli_test'

The rule that runs semgrep_scan safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Kali Security MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For semgrep_scan, this is the rule to start with:
semgrep_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.
The button opens the PolicyLayer dashboard: create your workspace, connect Kali Security MCP, apply this rule, and every semgrep_scan call is checked against it from then on.
Questions about semgrep_scan
semgrep_scan is a execute tool on the Kali Security MCP server. It is categorised as a Execute tool in the Kali Security MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Kali Security MCP server in PolicyLayer and add a rule for semgrep_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 Kali Security MCP. Nothing to install.
semgrep_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 semgrep_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 semgrep_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.
semgrep_scan is provided by the Kali Security MCP server (seac-25/kali-security-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
