Scan all active Polymarket markets for mispriced edges using volume/liquidity heuristics.
AI agents call scan_edges 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 reads and analyzes market data to identify potential mispricings. It retrieves market information and applies heuristics but does not execute trades, place orders, or commit any financial obligations. It is purely an analytical/read operation providing information to the user.

Attacks that exploit this kind of access
Scan all active Polymarket markets for mispriced edges using volume/liquidity heuristics. It is categorised as a Read tool in the Polymarket MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Polymarket MCP Server MCP server in PolicyLayer and add a rule for scan_edges: 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.
scan_edges 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 scan_edges 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 scan_edges. 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.
scan_edges is provided by the Polymarket MCP Server MCP server (miles0sage/polymarket-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
