WHAT IT DOES

What watchlist.add does on Polymarket Agent Mcp

AI agents use watchlist.add to create or update resources in Polymarket Agent Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Polymarket Agent Mcp environment.

RISK

Why watchlist.add is rated Medium

This tool modifies a watchlist by adding or removing wallet addresses. It is a reversible write operation (addresses can be added back or removed). However, misuse could lead to unwanted copy-trading of malicious wallets, which has downstream financial risk. The direct action itself is a Write, not Financial, since it only configures monitoring rather than executing trades directly.

From the tool's definition 'Add or remove an Ethereum wallet address from the copy trading watchlist' — creates or modifies the watchlist configuration reversibly

RECOMMENDED RULE

The rule that runs watchlist.add safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Polymarket Agent Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For watchlist.add, this is the rule to start with:

watchlist.add Rate-limited

watchlist.add stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
