Installation

To use the MCP server, you'll need an API key. You can create and manage API keys in SimpleLocalize > Settings > Credentials:

To run the server in a client like Claude Desktop, Cursor or Windsurf, add the following to your MCP config:

{
  "mcpServers": {
    "simplelocalize": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@simplelocalize/simplelocalize-mcp", "--api-key=SIMPLELOCALIZE_API_KEY"]
    }
  }
}

Replace SIMPLELOCALIZE_API_KEY with your API key
