## 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 connects a provider's hosted MCP server to Paperclip's shared vault, grants, policies, gateway, and audit trail. > - Gauge (`withgauge.com`) measures how AI answer engines mention and cite a brand. Its hosted MCP server also gives SEO, analytics and ads reports, and runs a content pipeline that can publish to a connected CMS. > - Gauge is not in the catalog. Operators must use the generic "Connect your own MCP server" flow. That flow has no branding, no organization guidance, and no warning about live CMS publishing. > - The connector playbook supports this provider with existing definition fields. The server supports dynamic client registration with a reviewed `mcp` scope, and it accepts an organization API key as a bearer header. > - This pull request adds the Gauge definition, its artwork, the research and permission-review ledger rows, documentation, and deterministic tests. > - The benefit is a branded, governed Gauge connection with browser sign-in, an API-key option, and a clear publish warning. ## Linked Issues or Issue Description **Problem or motivation** Marketing and growth teams use Gauge to track their brand in AI answers and to run content workflows. They want their Paperclip agents to read visibility, keyword and traffic data, and to prepare content. Gauge is not in the Apps catalog. Operators must paste the MCP URL into the generic remote-MCP flow, which gives no branding, no method guidance, and no warning that content tools can publish live. **Proposed solution** Add a catalog-only Gauge connection built from the connector playbook. Browser sign-in uses Gauge's dynamic client registration and requests only the reviewed `mcp` scope. The user selects one Gauge organization on the consent screen. An optional method sends a customer-created organization API key as an `Authorization: Bearer` header. Both methods warn the operator to set publish actions to Ask first. 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. The identity scopes that Gauge also advertises (`openid`, `profile`, `email`, `organizations`) are not requested, because Gauge selects the organization on its consent screen. A Gauge-specific `classifyRisk` rule was not added, because the tool names cannot be seen without an account. The generic rule already classifies `publish`, `create` and `update` tools as writes. **Roadmap alignment** This extends the existing self-serve remote-MCP connection catalog and does not overlap planned core work. ## What Changed - Added the `gauge` provider to `scripts/ingest-app-definitions.mjs` (category `analytics`, API-key placement, guidance, warnings, description) and regenerated `packages/shared/src/app-definitions/gauge.json` and the generated registry. - Added the Gauge row to the self-serve MCP research ledger with `dcr_or_api_key` auth and risk tier S3. - Added permission reviews for `gauge/mcp-oauth` (explicit scope `mcp`, from Gauge's live authorization-server metadata) and `gauge/mcp-api-key` (provider key), with evidence links. - Added Gauge's mark (`ui/public/brands/apps/gauge.png`, the avatar of Gauge's official GitHub organization) and the brand manifest entry. - Added gallery copy for the Gauge card. - Added `doc/connections/GAUGE.md` (endpoints, scopes, administrator setup, capabilities and policy, manifest, brand provenance, validation hook) and linked it from the connections README and the permission audit. - Tests: Gauge definition shape, store visibility and artwork, URL recognition, reviewed scope, bearer-header placement, the connect form's sign-in default and 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 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 server/src/__tests__/tool-access-service.test.ts` — 738 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` — clean. - `node scripts/ingest-app-definitions.mjs --definitions-only` produces no Gauge drift. - Manual: on a local instance, open Apps → Browse and confirm the Gauge card and icon. Open `/apps/connect?source=gauge` and confirm that sign-in is the default and that the API-key method is under Advanced. - Live metadata probe on 2026-10-08: an unauthenticated `initialize` on `https://app.withgauge.com/mcp` returns 401 with `resource_metadata`. Both `.well-known` documents return the recorded endpoints and scopes. Dynamic client registration succeeds. The authorize endpoint accepts `scope=mcp` and rejects an unknown scope with HTTP 400. ## Risks - Low risk to existing providers: the change is additive catalog data plus tests. The generated registry only gains one import. - Gauge content tools can publish to a connected CMS, including live, and a bulk keyword update replaces each prompt's keyword list. Both methods warn the operator, and the API-key helper text tells operators to set publish actions to Ask first. - Gauge API keys are not scoped and reach the whole organization. Paperclip cannot narrow an issued key. - The permission-review ledger records live proof for both methods as not run. The lifecycle checklist in `doc/connections/GAUGE.md` still needs a documented pass with a Gauge organization. > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR.
