Overview
The OpenSea Agent Skill is an official ProjectOpenSea tool for AI coding assistants that lets agents interact with the OpenSea API to query NFT and token data, list NFTs, fetch listings/offers, and swap ERC-20 tokens via CLI, scripts, or the OpenSea MCP server (mcp.opensea.io). It works with MCP-compatible apps (Claude, Cursor, VS Code, etc.) and supports managed signers including Privy, Turnkey, Fireblocks, and Bankr. Listed here as the agent skill/MCP, not the marketplace itself.
