Test the endpoint from a terminal
This lists the tools without a key and without calling any of them:
curl -s https://insidewell-api.cybermaxtools.com/mcp \
-H 'content-type: application/json' \
-H 'accept: application/json, text/event-stream' \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'If it does not work
- Custom connectors connect from Anthropic's cloud, not your computer; our servers are public, so no allowlisting is needed.
- Free plans can add one custom connector.
- To change the URL or header, remove the connector and add it again.
- The free tier has a daily limit (see the pricing line above); a paid key raises it.
