get_trades
AI agents call get_trades 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.
This tool retrieves trade data from Polymarket's public CLOB (Central Limit Order Book). It has no side effects, does not modify data, execute code, or involve financial transactions—it only queries and returns historical trade information. The read-only server design and sibling tool patterns confirm this is a simple data retrieval operation.
From the tool's definition Server is described as 'read-only interface' and tool name 'get_trades' follows the pattern of sibling tools (get_activity, get_book, get_positions, get_price_history) which are all retrieval operations.
Attacks that exploit this kind of access
get_trades. 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 get_trades: 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.
get_trades 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 get_trades 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 get_trades. 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.
get_trades 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.
