AI agents call list_available_scanners to retrieve information from Secscan without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and presents information about which scanners are available and their installation status. It does not execute scans, modify any data, delete anything, or trigger external operations. It is a simple read/query operation with no side effects or blast radius.

List all supported scanners and whether each engine CLI is installed. It is categorised as a Read tool in the Secscan MCP Server, which means it retrieves data without modifying state.
Register the Secscan MCP server in PolicyLayer and add a rule for list_available_scanners: 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 Secscan. Nothing to install.
list_available_scanners 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_available_scanners 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_available_scanners. 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_available_scanners is provided by the Secscan MCP server (openjkai/secscan_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
