Claude Code
claude mcp add --transport http --scope user tritonium https://api.tritonium.com/mcp
/mcp in Claude Code, choose tritonium and sign in. From a terminal, claude mcp login tritonium does the same. Over SSH, add --no-browser: open the link it prints on your own computer, and after you approve, paste the address your browser ends up on back into the terminal.
Use an API key instead
First create a key and store it in the TRITONIUM_API_KEY environment variable, as described under API keys.
claude mcp add --transport http --scope user tritonium https://api.tritonium.com/mcp --header 'Authorization: Bearer ${TRITONIUM_API_KEY}'
${TRITONIUM_API_KEY} literal in the saved configuration; Claude Code reads the variable when it connects. Check the connection with claude mcp list.
