Why polymarket_markets is rated Low
Even though polymarket_markets only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access

polymarket_markets is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
