What is the Tatum (Blockchain Infra) MCP Server?
Connect your Tatum account to any AI agent to streamline blockchain infrastructure management. Access real-time data, gas estimates, and portfolio tracking across 40+ protocols through natural language.
What you can do
- Fee Estimation — Get recommended fees or estimate gas for EVM transactions to optimize costs using
get_recommended_feeandestimate_evm_gas. - Portfolio Tracking — Retrieve balances for native assets, ERC-20 tokens, and NFTs across multiple addresses with
get_wallet_portfolio. - Real-time Monitoring — Create and manage webhook subscriptions for incoming/outgoing transactions using
create_subscriptionandlist_subscriptions. - Transaction History — Query detailed historical data for specific blockchain addresses via
get_transaction_history. - Exchange Rates — Get live exchange rates between crypto and fiat currencies using
get_exchange_rate.
How it works
- Subscribe to this server
- Enter your Tatum API Key
- Start querying blockchain data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Web3 Developers — Quickly estimate gas and debug transactions without leaving the IDE
- DeFi Analysts — Monitor portfolios and exchange rates in real-time through conversation
- Ops Teams — Automate webhook management for blockchain event monitoring

Every tool call from Pydantic AI to the Tatum (Blockchain Infra) MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I estimate gas for a specific EVM transaction before sending it?
Yes! Use the estimate_evm_gas tool by providing the chain, sender, recipient, and amount. It will return the estimated gas limit and price for that specific interaction.
How do I monitor a wallet for new incoming transactions automatically?
You can use the create_subscription tool to set up a webhook. This allows you to receive real-time notifications whenever a transaction occurs on the specified address and chain.
Can I check balances for multiple token types at once?
Yes, the get_wallet_portfolio tool allows you to specify token types like 'native', 'fungible' (ERC-20), and 'nft' to get a comprehensive view of an address's holdings.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Tatum (Blockchain Infra) MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
