## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Agents reach external services through the Apps catalog. Each catalog entry is a reviewed `AppDefinition` that wires a provider's hosted MCP server into Paperclip's shared vault, grants, policies, gateway, and audit trail. > - Neon is a widely used serverless Postgres provider with an official hosted MCP server, but it is not in the catalog. Teams that run their databases on Neon must use the generic "connect your own MCP server" path, which has no branding, no guidance, and no project or read-only controls. > - The connector playbook requires a catalog entry for a provider like this: the hosted server supports dynamic client registration and bearer API keys, and the common definition fields can express every option Paperclip can serialize. > - This pull request adds the Neon definition, its official artwork, the research and permission-review ledger rows, documentation, and deterministic tests, without any provider-specific runtime code. > - The benefit is a one-click, governed Neon connection with optional project pinning and read-only mode, and a documented path to live qualification. ## Linked Issues or Issue Description **Problem or motivation** Neon is a common Postgres host for the applications agents work on, but Paperclip's Apps catalog has no Neon entry. Operators who want agents to inspect schemas, run SQL, or manage branches must paste the MCP URL into the generic remote-MCP flow, which gives no branding, no provider guidance, no project boundary, and no read-only switch. **Proposed solution** Add a catalog-only Neon connection built from the connector playbook: browser sign-in through Neon's dynamic client registration with the reviewed `read` and `write` scopes, or a customer API key sent as an Authorization bearer header. Both methods expose Neon's documented `projectId` pin and `readonly` switch as optional Advanced fields. Every discovered tool stays governed by the normal per-action policies. **Alternatives considered** A plugin was not needed because no custom UI, tables, workers, or webhooks are involved. A separate read-only method was not added because the playbook treats read-only switches as advanced fields rather than methods. Neon's repeatable `category` query filter was left out because tenant fields serialize lists as one comma-joined value, so it cannot be sent correctly without new runtime code; per-action policies cover catalog narrowing instead. **Roadmap alignment** This extends the existing self-serve remote-MCP connection catalog and does not overlap planned core work. ## What Changed - Added the `neon` provider to `scripts/ingest-app-definitions.mjs` (category, API-key placement, methods, tenant fields, guidance, warnings) and regenerated `packages/shared/src/app-definitions/neon.json` plus the generated registry. - Added the Neon row to the self-serve MCP research ledger with `dcr_or_api_key` auth and risk tier S4. - Added permission reviews for `neon/mcp-oauth` (explicit scopes `read`, `write`, taken from Neon's live authorization-server metadata) and `neon/mcp-api-key` (provider key), with evidence links. - Added Neon's official tile icon (`ui/public/brands/apps/neon.png`, copied byte-for-byte from the icon linked by neon.com) and the brand manifest entry. - Added prosumer gallery copy for the Neon card. - Added `doc/connections/NEON.md` (service involvement, endpoints, administrator setup, capabilities and policy, manifest, brand provenance, validation hook) and linked it from the connections README and the permission audit. - Tests: Neon definition shape, store visibility and artwork, URL recognition, reviewed scopes with scope-widening rejection, URL projection of the project pin and read-only flag, invalid project ID rejection, the connect form's API-key gating, and the pinned catalog counts. ## Verification - `pnpm exec vitest run packages/shared/src/app-definitions.test.ts packages/shared/src/app-definitions-url.test.ts` — 34 passed. - `pnpm exec vitest run server/src/__tests__/tool-access-service.test.ts` — 367 passed. - `pnpm exec vitest run ui/src/pages/apps/AppsConnect.test.tsx ui/src/pages/apps/Browse.test.tsx ui/src/lib/app-brand-assets.test.ts ui/src/pages/apps/AppLogo.brand-assets.test.tsx` — all passed. - `node scripts/check-app-brand-assets.mjs` and `node --test scripts/app-brand-validation.test.mjs` — passed. - `pnpm --filter @paperclipai/shared typecheck`, `pnpm --filter @paperclipai/server typecheck`, `pnpm --filter @paperclipai/ui typecheck`, `pnpm check:token-gates` — clean. - Manual: in a local instance, open Apps → Browse, confirm the Neon card and icon, open `/apps/connect?source=neon`, confirm both methods, the Advanced project pin and read-only toggle, and that Connect enables after an API key is entered. The operator completed a live connection against a Neon account on this build. - Live metadata probed on 2026-10-02: both `.well-known` documents at `mcp.neon.tech` return the recorded endpoints and scopes; an unauthenticated `initialize` returns 401 with `resource_metadata`. ## Risks - Low risk to existing providers: the change is additive catalog data plus tests. The generated registry only gains one import. - Neon's hosted server grants broad project and database management. The definition carries two warnings, recommends a development project, and keeps every write under the normal action policies; the read-only switch is enforced by Neon's server, not locally. - The permission-review ledger records live proof for both methods as not run; the full lifecycle checklist in `doc/connections/NEON.md` still needs a documented pass before the entry is considered fully qualified. > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR.
