An MCP server that provides real-time gas price predictions across multiple blockchains, powered by Blocknative.
The Blocknative MCP Server is a robust Model Context Protocol server designed to deliver real-time gas price predictions across various blockchains. It leverages Blocknative's advanced technology to provide accurate and timely gas price data, which is crucial for blockchain transactions. The server supports multiple blockchains, including Ethereum Mainnet, and offers tools for predicting gas prices, estimating transaction costs, and listing supported chains. It is built with asynchronous capabilities using `httpx` for efficient non-blocking HTTP requests. The server can be accessed with or without a Blocknative API key, although high-frequency access requires an API key. The server is compatible with the FastMCP framework and can be integrated with platforms like Claude Desktop for enhanced functionality.
