list_events
AI agents call list_events to retrieve information from Polymarket without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to retrieve or enumerate event information from Polymarket without modifying, executing, or deleting data. The server's read-only nature and the tool's naming pattern (list_*) are consistent with data retrieval operations, which fall under the Read category.
From the tool's definition Server is explicitly described as 'read-only interface' and 'list_events' is a standard data retrieval pattern; no description provided for the tool itself, but context strongly suggests listing/querying event data.
Attacks that exploit this kind of access
list_events. It is categorised as a Read tool in the Polymarket MCP Server, which means it retrieves data without modifying state.
Register the Polymarket MCP server in PolicyLayer and add a rule for list_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. Nothing to install.
list_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 list_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 list_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.
list_events is provided by the Polymarket MCP server (pr1m8/polymarket-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
