Detect file type and return recommended REMnux analysis tools without executing them.
AI agents call suggest_tools to retrieve information from REMnux MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs passive analysis—it examines a file type and returns recommendations without taking any action. It is purely informational retrieval with no capability to modify, execute, delete, or move data. The severity is low because misuse would only result in irrelevant tool suggestions, causing no operational harm.
From the tool's definition Tool name and description indicate 'Detect file type and return recommended REMnux analysis tools without executing them.' The explicit clause 'without executing them' and the use of 'detect' and 'return' (query verbs) confirm this is a read-only operation…
Documented attack patterns abuse exactly the kind of access suggest_tools gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and REMnux MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for suggest_tools:
{
"version": "1",
"default": "deny",
"tools": {
"suggest_tools": {}
}
}suggest_tools is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Detect file type and return recommended REMnux analysis tools without executing them. It is categorised as a Read tool in the REMnux MCP Server MCP Server, which means it retrieves data without modifying state.
Register the REMnux MCP Server MCP server in PolicyLayer and add a rule for suggest_tools: 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 REMnux MCP Server. Nothing to install.
suggest_tools 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 suggest_tools 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 suggest_tools. 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.
suggest_tools is provided by the REMnux MCP Server MCP server (remnux/remnux-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
