UTC hour-of-day histogram + best-effort timezone inference.
AI agents call get_wallet_timing_pattern to retrieve information from Polymarket Research without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and analyzes temporal patterns from existing wallet or market data. It does not create, modify, delete, execute code, or move funds. The 'Read-only' server designation and the data-retrieval nature of the operation (histogram generation and timezone inference from existing data) clearly place this in the Read category with low severity, as misuse would at worst expose timing patterns of…
From the tool's definition Tool is described as 'UTC hour-of-day histogram + best-effort timezone inference', which retrieves and analyzes timing pattern data without modifying or deleting anything.
Attacks that exploit this kind of access
UTC hour-of-day histogram + best-effort timezone inference. It is categorised as a Read tool in the Polymarket Research MCP Server, which means it retrieves data without modifying state.
Register the Polymarket Research MCP server in PolicyLayer and add a rule for get_wallet_timing_pattern: 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 Research. Nothing to install.
get_wallet_timing_pattern 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_wallet_timing_pattern 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_wallet_timing_pattern. 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_wallet_timing_pattern is provided by the Polymarket Research MCP server (yoppav/polymarket-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
