Why query_table is rated Low
Tool queries data with filters; no side effects, mutations, or code execution capability.
From the tool's definition Query allowlisted table with parameterized filters and pagination.
Attacks that exploit this kind of access
The rule that runs query_table safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Etfedge, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For query_table, this is the rule to start with:
query_table is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Etfedge, apply this rule, and every query_table call is checked against it from then on.

Yes. Add a rate_limit block to the query_table 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 query_table. 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.
