AI agents call lexq_simulation_list to retrieve information from LexQ without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays simulation history—a read-only operation with no side effects. The word 'list' combined with 'optional filters' confirms it is a data retrieval tool. No evidence suggests it creates, executes, deletes, or commits any changes. Blast radius is minimal as misuse would only expose historical simulation data.
From the tool's definition Tool name 'lexq_simulation_list' and description 'List simulation history with optional filters' indicate a retrieval operation that queries existing simulation records without modifying, executing, or deleting data.
Attacks that exploit this kind of access
List simulation history with optional filters. It is categorised as a Read tool in the LexQ MCP Server, which means it retrieves data without modifying state.
Register the LexQ MCP server in PolicyLayer and add a rule for lexq_simulation_list: 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 LexQ. Nothing to install.
lexq_simulation_list 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 lexq_simulation_list 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 lexq_simulation_list. 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.
lexq_simulation_list is provided by the LexQ MCP server (lexq-io/lexq-cli). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
