What is the OpenSea MCP Server?
Connect OpenSea to your AI agent to navigate the NFT ecosystem with ease. From tracking trending collections to deep-diving into specific token traits, this server provides real-time access to the largest digital marketplace.
What you can do
- Market Insights — Get trending and top collections, or fetch comprehensive stats like volume and floor prices using
get_trending_collectionsandget_collection_stats. - NFT Deep-Dive — Retrieve full metadata, rarity, and ownership details for any NFT with
get_nftandget_nft_metadata. - Collection Analysis — List collection traits, holders, and detailed fee structures via
get_collection_traitsandget_collection_holders. - Wallet Monitoring — Check account profiles and fungible token balances for any wallet address with
get_accountandget_token_balances. - Multi-Chain Support — Query data across all blockchains supported by OpenSea using
get_chains.
How it works
- Subscribe to this server
- Enter your OpenSea API Key
- Start analyzing the NFT market from Claude, Cursor, or any MCP-compatible client
No more manual searching through marketplace tabs. Your AI acts as a dedicated floor price tracker and portfolio analyst.
Who is this for?
- Web3 Developers — instantly retrieve NFT metadata and contract details directly from the code editor.
- NFT Collectors & Traders — monitor floor prices, volume trends, and collection holders without leaving the chat.
- Data Analysts — automate the retrieval of collection statistics and trait distributions for market research.

Why OpenAI Agents SDK?
The OpenAI Agents SDK auto-discovers all 35 tools from OpenSea through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns. chain multiple agents where one queries OpenSea, another analyzes results, and a third generates reports, all orchestrated through Vinkius.

OpenSea in OpenAI Agents SDK
OpenSea and 4,000+ other MCP servers. One platform. One governance layer.
Teams that connect OpenSea to OpenAI Agents SDK through Vinkius don't need to source, host, or maintain individual MCP servers. Every tool call runs inside a hardened runtime with credential isolation, DLP, and a signed audit chain.

Why teams choose Vinkius for OpenSea in OpenAI Agents SDK
The OpenSea MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 35 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in OpenAI Agents SDK only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
OpenSea for OpenAI Agents SDK
Every tool call from OpenAI Agents SDK to the OpenSea MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I check the floor price and volume for a specific NFT collection?
Yes! Use the get_collection_stats tool with the collection slug. The agent will return real-time metrics including floor price, total volume, and sales counts.
How do I retrieve the image and metadata for a specific NFT?
You can use the get_nft_metadata tool by providing the chain, contract address, and token ID. It returns detailed metadata including image URLs and external links.
Can I see which wallets hold the most items in a collection?
Yes, the get_collection_holders tool provides a list of wallet addresses that currently hold items within a specific collection slug.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
