Hello, how can I pass in the corresponding key through a command for something like this with env

{ "mcpServers": { "baidu-maps": { "command": "uvx", "args": [ "mcp-server-baidu-maps" ], "env": { "BAIDU_MAPS_API_KEY": "xxx" } } } }

Is that so?

uvx mcpo --port 8000 -- uvx mcp-server-baidu-maps --BAIDU_MAPS_API_KEY=xxxx

If I understand the implementation correctly, then the defined env variables should actually be forwarded. But that doesn't seem to happen for me? maybe it's a bug?

you can use the --config parameter and add the environment variables to the claude json config.
This works like a charm
