Connect your agent to Sealround’s local MCP server. Read the sale rules first, then approve the price limit, spending limit and deposit cap for a sealed bid.

Connect your client

Approve a deposit cap

  1. Ask the agent to call sealround_list_sales, then read the sale’s rules with sealround_get_sale.
  2. For a write, configure a dedicated testnet account’s local key file through SEALROUND_KEY_FILE. Use a private config and keep the key file off chat and source control. Set SEALROUND_RELAYER_URL if you have a testnet relayer.
  3. Review the sale ID, max_price, max_spend, and max_deposit before approving sealround_place_bid. Approve direct gas fees separately if the relayer cannot sponsor the call.

max_deposit caps the public deposit on one call. Cross-sale spending has no cumulative cap. Price and spend limits stay sealed, with the recovery file on your machine.
