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.

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 LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
