Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.

Permissions Found in Source Code

Found by scanning the linked source code. This listing connects to a hosted endpoint, so none of this runs on your machine: it describes what the server software does where it is hosted.

HTTP Network Access

Connects to external APIs or services over the internet.

How to Connect

Remote Plugin

No local installation needed. Your AI client connects to the remote endpoint directly.

Add this to your MCP configuration to connect:

{
  "mcpServers": {
    "com-alchemy-mcp": {
      "url": "https://mcp.alchemy.com/mcp"
    }
  }
}

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-server npm package will stop working on September 30, 2026. Use the hosted Alchemy MCP Server at https://mcp.alchemy.com/mcp instead.

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.

{
  "mcpServers": {
    "alchemy": {
      "type": "streamable-http",
      "url": "https://mcp.alchemy.com/mcp"
    }
  }
}
{
  "servers": {
    "alchemy": {
      "type": "http",
      "url": "https://mcp.alchemy.com/mcp"
    }
  }
}

For any other MCP-compatible client, point it at https://mcp.alchemy.com/mcp using Streamable HTTP transport.

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.
