What is the BTCFi API MCP Server?

The BTCFi API MCP Server is a Bitcoin data service interface specifically designed for AI assistants (such as Claude, ChatGPT, Gemini). Through the Model Context Protocol (MCP) standard, it enables AI assistants to directly access real-time data on Bitcoin, Ethereum, and Solana, including prices, transaction fees, address information, and whale transaction alerts.

How to use the BTCFi API MCP Server?

You can use it by installing the MCP server package and configuring it in your AI assistant client. After installation, the AI assistant can directly call the Bitcoin data query function without manually accessing the API or website.

Applicable scenarios

Suitable for AI application scenarios that require real-time cryptocurrency data, such as investment analysis assistants, trading monitoring robots, blockchain research tools, and risk analysis systems.

Main features

Multi-chain data support

Supports real-time data queries for the three major blockchains of Bitcoin, Ethereum, and Solana

33 data endpoints

Provides 33 API endpoints for core data, intelligent analysis, security detection, ZK proof, etc.

x402 micropayments

Pay per query, only $0.01 - $0.05 per time, no subscription or API key required

MCP protocol integration

Fully compatible with the Model Context Protocol, can be seamlessly integrated with AI assistants such as Claude Desktop

Real-time whale monitoring

Automatically detects and pushes large - value transaction alerts, providing buy - sell signal analysis

Security threat detection

Built - in 8 YARA pattern threat detection, providing address risk scores

Zero - knowledge proof

Supports ZK proof verification for balance ranges, UTXO ages, set membership, etc.

Free Telegram bot

Provides a completely free Telegram bot with 15 commands and real - time alerts

Advantages

No API key or account registration required, reducing the usage threshold

Pay per query, with transparent and controllable costs, suitable for low - frequency usage scenarios

Supports multiple payment networks (Base, Solana), with flexible payment options

High real - time data, with a high update frequency

Provides a free Telegram bot as an alternative

Open - source and transparent, the code can be viewed on GitHub

High security, supporting request signatures and encrypted responses

Limitations

Requires configuring a cryptocurrency wallet for payment, which has a certain learning cost for beginners

Currently mainly targeted at developers and technical users, ordinary users may need to use it indirectly through AI assistants

The data coverage is limited to Bitcoin, Ethereum, and Solana, and does not support other chains

Requires installing and configuring the MCP client, which has a certain technical threshold

How to use

Install the MCP server

Install the BTCFi MCP server package via npm

Configure the AI assistant client

Add the server configuration in Claude Desktop or other MCP - supported clients

Set up the payment wallet

Prepare a cryptocurrency wallet that supports the Base or Solana network and deposit a small amount of USDC for query fees

Start querying

Directly ask the AI assistant for Bitcoin - related data, such as 'What is the current Bitcoin price?' or 'View the transaction history of address bc1q...'

Usage examples

Investment decision support

The AI assistant helps users analyze the timing of Bitcoin investment, comprehensively considering price trends, network congestion, and whale activities

Address security review

Check the security of the receiving address before transferring funds to avoid sending funds to high - risk addresses

Transaction fee optimization

Helps users choose the best transaction confirmation time and fees

Whale activity monitoring

Monitors large - value transactions in real - time to keep abreast of market trends
