BTCFi

You can access Bitcoin data and intelligence through an MCP server that lets AI agents query 31 endpoints using lightweight micropayments. This setup enables fast, permissionless access to Bitcoin data without API keys or subscriptions, supporting practical use in AI workflows and automated decision making.

How to use

To run the MCP server for Bitcoin data, start the MCP client that connects to the BTCFi MCP server. You will then query endpoints such as fees, mempool status, address data, UTXOs, transactions, blocks, risk scores, whale alerts, and network health. All interactions are paid via the x402 USDC micropayments model, with no keys required and no signup.

How to install

Prerequisites: you need Node.js and npm installed on your machine.

Install the MCP client and run the BTCFi MCP server client as shown.

# Start the BTCFi MCP client for AI agents
npx @aiindigo/btcfi-mcp

# For developers who want the SDK (optional for client interactions)
npm install @aiindigo/btcfi

Additional content and notes

Key capabilities include core data access (fees, mempool, address data, UTXOs, transactions, blocks), intelligence features (fee predictions, whale alerts, risk scoring, network health), security analyses (YARA-style threat detection), Solv Protocol data (reserves, yield, liquidity, risk), ZK proofs (balance ranges, UTXO age, set membership), real-time streams (live blocks, whale transactions), and system status checks. You can interact with humans or agents via supported clients and rely on the built-in security model to protect requests and responses.

Security and payments

Payments are processed through a dual-network x402 micropayments system in USDC. No API keys or sign-up are required; you pay per query and receive the data in return. Core security features include wallet-based request signing, encrypted responses, zero-knowledge proofs, nonce replay protection, and cryptographic receipts.
