query_events
AI agents call query_events to retrieve information from PolyMarket MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries event data from PolyMarket without side effects. The server's stated purpose is enabling LLM agents to 'search, navigate, and filter' events, which are typical read operations.
From the tool's definition Tool name 'query_events' combined with server description stating 'search, navigate, and filter PolyMarket prediction market events' and 'queries across markets, liquidity, and analytics' indicates data retrieval functionality.

Register the PolyMarket MCP Server MCP server in PolicyLayer and add a rule for query_events: 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 PolyMarket MCP Server. Nothing to install.
query_events 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 query_events 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_events. 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.
query_events is provided by the PolyMarket MCP Server MCP server (undiabler/polymarket-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
