approve_allowances

MCP tool from MCP Polymarket by BrainDAO

Grant the pUSD and Conditional Token approvals required for Polymarket V2 trading and position management. Automatically approves only contracts that do not already have permission. Approvals are revocable at any time in your wallet.

How to use it

Project documentation lists approve_allowances for the MCP Polymarket MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
