Compatible with every major AI agent and IDE
What is the Zerion (DeFi Portfolio) MCP Server?
Connect your AI agent to the Zerion API to gain deep insights into any Web3 wallet. This server enables real-time monitoring of DeFi positions, NFT valuations, and historical performance across all major blockchains.
What you can do
- Portfolio Overview — Get total value, asset distribution, and net worth for any wallet address or a set of multiple addresses.
- DeFi & Token Positions — Inspect specific fungible token balances and complex DeFi positions (liquidity pools, lending, etc.).
- Transaction History — Retrieve human-readable transaction logs to understand past on-chain activity.
- PnL Analysis — Calculate realized and unrealized gains to track investment performance over time.
- NFT Analytics — Fetch NFT portfolio values, individual holdings, and collection-grouped data.
- Market Data — List supported chains, dApps, and check real-time gas prices across networks.
How it works
- Subscribe to this server
- Enter your Zerion API Key
- Start querying on-chain data from Claude, Cursor, or any MCP-compatible client
No more manual searching on block explorers. Your AI acts as a personal crypto analyst, providing instant data on any wallet's health and history.
Who is this for?
- Crypto Investors — quickly check your total net worth and PnL without opening multiple apps.
- Web3 Developers — integrate wallet balance and transaction checks directly into your development workflow.
- Data Analysts — aggregate data from multiple wallets to identify trends or audit holdings.

Why CrewAI?
When paired with CrewAI, Zerion (DeFi Portfolio) becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Zerion (DeFi Portfolio) tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.
- —
Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools
- —
CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the
mcpsparameter and agents auto-discover every available tool at runtime - —
Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls
- —
Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

Frequently asked questions
Can I track the total value of multiple wallets at once?
Yes! Use the get_wallet_set_portfolio tool by providing a comma-separated list of addresses. The agent will return an aggregated summary of the total net worth across all specified wallets.
Does this server show my profit and loss (PnL) for specific tokens?
Absolutely. The get_wallet_pnl tool fetches both realized and unrealized gains for a wallet, allowing your AI to explain your investment performance in detail.
Can I see the estimated value of my NFT collection?
Yes. You can use get_wallet_nft_portfolio for a high-level summary or get_wallet_nft_collections to see your holdings grouped by their respective collections with valuation data.
How does CrewAI discover and connect to MCP tools?
CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.
Can different agents in the same crew use different MCP servers?
Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.
What happens when an MCP tool call fails during a crew run?
CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.
Can CrewAI agents call multiple MCP tools in parallel?
CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.
Can I run CrewAI crews on a schedule (cron)?
Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.
MCP tools not discovered
Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.
Agent not using tools
Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".
Timeout errors
CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.
Rate limiting or 429 errors
Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
