This MCP server fetches gas price predictions, base fees, and confidence-level fee tables across multiple blockchains using Blocknative's Gas Price and Chains APIs. It exposes tools to predict gas prices, estimate transaction costs (in Gwei and ETH), and list supported chains, and is implemented asynchronously with httpx for non-blocking requests. The server integrates with FastMCP and can be run locally or installed for Claude Desktop, and supports optional use of a Blocknative API key for higher-frequency access.
