Bring Web3
to Pydantic AI
Learn how to connect Blockdaemon (Blockchain Infrastructure) to Pydantic AI and start using 4 AI agent tools in minutes. Fully managed, enterprise secure, and ready to use without writing a single line of code.
Compatible with every major AI agent and IDE
What is the Blockdaemon (Blockchain Infrastructure) MCP Server?
Connect your Blockdaemon account to any AI agent to interact with major blockchain protocols through a single, unified interface. This MCP server leverages the Ubiquity API to provide seamless access to multi-chain data.
What you can do
- Block Exploration — Retrieve block identifiers and metadata for protocols like Bitcoin, Ethereum, Solana, and Polkadot using
list_blocks. - Transaction Tracking — Query full transaction histories for specific account addresses across supported networks with
list_transactions. - UTXO Management — Fetch Unspent Transaction Outputs for UTXO-based chains (Bitcoin, Dogecoin, Litecoin) using
get_utxos. - Financial Reporting — Generate detailed financial reports for addresses on protocols like Algorand, Stellar, and Tezos via
get_financial_report. - Multi-Network Support — Switch between mainnet and testnet environments effortlessly for development and auditing.
How it works
- Subscribe to this server
- Enter your Blockdaemon API Key
- Start querying blockchain data directly from Claude, Cursor, or any MCP client
Who is this for?
- Web3 Developers — Debug transactions and verify block data without leaving your IDE.
- Data Analysts — Aggregate financial reports and transaction histories for cross-chain auditing.
- Crypto Operations — Monitor wallet activity and UTXO sets for treasury management.

Why Pydantic AI?
Pydantic AI validates every Blockdaemon (Blockchain Infrastructure) tool response against typed schemas, catching data inconsistencies at build time. Connect 4 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.
- —
Full type safety: every MCP tool response is validated against Pydantic models, catching data inconsistencies before they reach your application
- —
Model-agnostic architecture. switch between OpenAI, Anthropic, or Gemini without changing your Blockdaemon (Blockchain Infrastructure) integration code
- —
Structured output guarantee: Pydantic AI ensures tool results conform to defined schemas, eliminating runtime type errors
- —
Dependency injection system cleanly separates your Blockdaemon (Blockchain Infrastructure) connection logic from agent behavior for testable, maintainable code

Why teams choose Vinkius for Blockdaemon (Blockchain Infrastructure) in Pydantic AI
The Blockdaemon (Blockchain Infrastructure) 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 4 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in Pydantic AI 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
Blockdaemon (Blockchain Infrastructure) for Pydantic AI
Every tool call from Pydantic AI to the Blockdaemon (Blockchain Infrastructure) MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Which protocols are supported for financial reports?
The get_financial_report tool currently supports Algorand, Polkadot, Stellar, Tezos, and XRP.
Can I filter transactions by date?
Yes, the list_transactions tool allows you to provide 'from' and 'to' Unix timestamps to narrow down your search.
How do I check unspent balances for Bitcoin?
Use the get_utxos tool with the 'bitcoin' protocol and the specific wallet address. You can also toggle 'check_mempool' to include unconfirmed transactions.
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 Blockdaemon (Blockchain Infrastructure) MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
