# review before running: this installs third-party code
$ claude mcp add tirith-gateway -- tirith gateway run --upstream-bin tirith --upstream-arg mcp-server --config ~/.config/tirith/gateway.yaml
$ npx degit sheeki03/tirith/.claude ./rig-tirith  # inspect, then merge into .claude/

MCP servers are added to Claude Code at local scope; env vars are shown as YOUR_… placeholders — we never store values. Files are fetched with degit into a separate folder so you can review before merging.

$ claude mcp add tirith-gateway -- tirith gateway run --upstream-bin tirith --upstream-arg mcp-server --config ~/.config/tirith/gateway.yaml

Merge into .claude/settings.json (project) or ~/.claude/settings.json (user). Hook commands reference scripts in the source repo — copy those too.
