AI agents call suggest_queries to retrieve information from Trace without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
suggest_queries performs pure data retrieval and analysis of project metadata. It displays statistics and example tool calls without modifying any code, configuration, or project state. The explicit 'Read-only' designation confirms no write, execute, or destructive operations occur.
From the tool's definition Tool description explicitly states 'Read-only' and 'Onboarding helper' that 'shows' information (topFiles, topSymbols, languageStats, exampleQueries). Operations are: retrieves/queries data with no side effects.
Documented attack patterns abuse exactly the kind of access suggest_queries gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Trace, and nothing reaches the server without passing your rules. This is the rule we recommend for suggest_queries:
{
"version": "1",
"default": "deny",
"tools": {
"suggest_queries": {}
}
}suggest_queries is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Onboarding helper: shows top imported files, most connected symbols (PageRank), language stats, and example tool calls. Call this first when exploring an unfamiliar project. For a structured project map use get_project_map instead. Read-only. Returns JSON: { topFiles, topSymbols, languageStats, exampleQueries }. It is categorised as a Read tool in the Trace MCP Server, which means it retrieves data without modifying state.
Register the Trace MCP server in PolicyLayer and add a rule for suggest_queries: 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 Trace. Nothing to install.
suggest_queries 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_queries 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_queries. 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_queries is provided by the Trace MCP server (nikolai-vysotskyi/trace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
