You need to remove the env entry from your config file. Instead, pass the environment variable via the command line when running mcpo.

{
  "mcpServers": {
    "tavily": {
      "command": "npx",
      "args": [
        "-y",
        "tavily-mcp"
      ]
    }
  }
}

mcpo --env "TAVILY_API_KEY=tvly-dev-pkqxxxxxxxxxxxxxxxxxxxxxkj" --config tavily.json

This works for me using the Perplexity MCP Server.
