How to connect Ethereum Keystore Encryption

Ethereum Keystore Encryption runs locally from a Python package published to PyPI: keystore-mcp-server version 1.0.0. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Python; clients usually start it with uvx (from uv) or after pip install — the usual command is uvx keystore-mcp-server.

In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):

{
  "mcpServers": {
    "keystore-mcp-server": {
      "command": "uvx",
      "args": [
        "keystore-mcp-server"
      ]
    }
  }
}
