search_images | Search openly licensed images by keyword across Openverse, NASA, The Met, Art Institute of Chicago and Cleveland Museum of Art.

Test the endpoint from a terminal
This lists the tools without a key and without calling any of them:
curl -s https://commonkite.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
- Each server is its own [mcp_servers.<name>] table; keep the name to letters, digits, dashes and underscores.
- For a fixed header value instead of an environment variable, Codex also documents http_headers.
- The free tier has a daily limit (see the pricing line above); a paid key raises it.
