Alchemy MCP Server
[!IMPORTANT] The legacy local MCP server has been retired. Its source code has been removed from this repository, and the
@alchemy/mcp-servernpm package will stop working on September 30, 2026. Use the hosted Alchemy MCP Server athttps://mcp.alchemy.com/mcpinstead.
The hosted Alchemy MCP Server gives AI agents access to Alchemy's blockchain APIs and onchain data. It authenticates via OAuth — just sign in with your Alchemy account when prompted. No API key or local install required.

Migrating from the local server
If your MCP config runs the local server through npx, like this:
{
"mcpServers": {
"alchemy": {
"command": "npx",
"args": ["-y", "@alchemy/mcp-server"],
"env": {
"ALCHEMY_API_KEY": "YOUR_API_KEY"
}
}
}
}
replace that entry with the hosted server config for your client from the Setup section above. You can drop ALCHEMY_API_KEY from your MCP config; the hosted server signs you in with your Alchemy account instead.
