## Summary Follow-up to #19755. Simplifies `OAuthDiscoveryController` by dropping the `authorization_endpoint → frontend base URL` branch that was there to make `api.twenty.com/mcp` paste-able in MCP clients. We've decided not to support pasting `api.twenty.com/mcp` — users can paste `app.twenty.com/mcp`, `<workspace>.twenty.com/mcp`, or a custom domain, all of which serve both frontend and API. On those hosts, `authorization_endpoint` was already pointed at the same host as `issuer`, which is what we want. ## Change - Remove `isApiHost` helper and the `authorizeBase` branch — use `issuer` for `authorization_endpoint`. - Drop now-unused `TwentyConfigService` and `DomainServerConfigService` injections. - Drop duplicate `DomainServerConfigModule` import from `application-oauth.module.ts` (the module is no longer needed). Net diff: +1 / -22 across 2 files. ## Breaking change MCP clients configured with `https://api.twenty.com/mcp` will stop working. They should be reconfigured with the host matching the workspace they're connecting to (`<workspace>.twenty.com/mcp`, `app.twenty.com/mcp`, or a custom domain). ## Test plan - [x] `yarn jest --testPathPatterns="mcp-auth.guard"` → 2/2 passing (unchanged) - [x] `tsc --noEmit` clean on modified files - [ ] Manual verification on staging: `app.twenty.com/mcp` and `<workspace>.twenty.com/mcp` OAuth flow still works end-to-end Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>

Why Twenty
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
