Describe the problem/error/question
I have setup a custom mcp server running on AWS enviroment. I would like to pass env variables to the server in json format like below:
{
"mcpServers": {
"mindbodyHTTP-mcp": {
"command": "npx",
"args": [
"mcp-remote@latest",
"http://127.0.0.1:8080/mcp"
],
"env": {
"MINDBODY_API_KEY": "your_api_key",
"MINDBODY_SITE_ID": "-99",
"MINDBODY_SOURCE_NAME": "your_source_name",
"MINDBODY_SOURCE_PASSWORD": "your_source_password"
}
}
}
}
The MCP Client tool does not allow this to be added, where and How can I pass this to the MCP server? I am not running n8n locally, its the n8n cloud.
This works with the claude desktop, I cant find any a way to add this json to MCP Client tool. If there is another tool I need to use, please let me know.
What is the error message (if any)?
Please share your workflow
