AI agents call list_scan_jobs to retrieve information from SAST MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or enumerates scan job metadata and status information. Even though the description is empty, the name and context (a SAST security scanning platform) strongly suggest it performs a read-only query of scan history or active scans. There is no indication of execution, modification, deletion, or financial impact.
From the tool's definition Tool name 'list_scan_jobs' indicates a query/retrieval operation that lists existing scan jobs without modifying them. No side effects implied by the verb 'list'.
Documented attack patterns abuse exactly the kind of access list_scan_jobs 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 list_scan_jobs:
{
"version": "1",
"default": "deny",
"tools": {
"list_scan_jobs": {}
}
}list_scan_jobs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

list_scan_jobs. It is categorised as a Read tool in the SAST MCP Server MCP Server, which means it retrieves data without modifying state.
Register the SAST MCP Server MCP server in PolicyLayer and add a rule for list_scan_jobs: 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.
list_scan_jobs is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_scan_jobs 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 list_scan_jobs. 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.
list_scan_jobs 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.
