Overview

FlexYield is a blockchain RPC gateway MCP server that gives AI agents access to six mainnet chains with measured failover and per-call USDC billing. No signup is required to get an API key, making it quick to start routing blockchain queries through a reliable gateway.

The server runs remotely at https://flexyield.io/mcp, so you only need to point your MCP client to that endpoint—nothing to install locally. You'll authenticate with an API key. The latest release is v1.4.0.

FlexYield is listed in the Finance category on mcp.site and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you maintain FlexYield for flexyield.io, claim this listing to verify ownership and keep the information accurate.
