Alchemy MCP Server (Legacy — Not Actively Maintained)
This open-source Model Context Protocol (MCP) server runs Alchemy's blockchain APIs locally via STDIO. New users should use the hosted Alchemy MCP Server instead.
Remote MCP Server (Recommended)
The fastest way to get started is to connect to the hosted remote server at https://mcp.alchemy.com/mcp. It authenticates via OAuth — just sign in with your Alchemy account when prompted. No API key or local install required.

https://mcp.alchemy.com/mcpis the recommended and actively maintained MCP server. This repository contains the legacy local STDIO server, is not actively maintained, and may lag behind the hosted server's tool coverage and behavior. Alchemy plans to sunset this repository; new users should connect to the hosted server instead.
