To add a custom +provider, drop a YAML file in that directory (or set +`PAPERCLIP_OAUTH_PROVIDERS_DIR` to a directory of your own and put the YAML +there — entries from that directory are loaded after and merged with the +bundled configs). Set the corresponding `client_id` and `client_secret` env +vars and restart the server. See `server/oauth-providers/github.yaml` for the +canonical example. + +For providers with non-standard response shapes (Slack's `team` block, +Microsoft's `id_token` claim parsing, etc.), add a TypeScript shape module +under `server/src/oauth/shapes/` and wire it from the YAML's `shape:` field. +See `server/src/oauth/shapes/slack.ts` for the canonical example. + +## Plugin-contributed providers + +Plugins can ship OAuth providers via the `oauthProviders` block in the +plugin manifest. See `packages/plugins/sdk/src/define-oauth-provider.ts` +for the helper, and the plugin developer docs for the manifest schema. +A YAML entry with the same provider id always wins; plugin contributions +for a duplicate id are skipped with a `WARN` log. + +## Operations + +- **Refresh worker:** runs every 60s, leader-elected via Postgres + advisory lock. No additional config needed. +- **Token storage:** OAuth tokens live in `company_secrets` / + `company_secret_versions`, encrypted via the configured `SecretProvider`. +- **Logs:** all OAuth code paths emit structured pino logs with + `component=oauth`. Token material is never logged — `access_token`, + `refresh_token`, `id_token`, `code`, `code_verifier`, and `client_secret` + are redacted at the logger level. +- **Metrics:** `oauth_refresh_total`, `oauth_refresh_duration_seconds`, + `oauth_connections_by_status` (Prometheus, existing pattern). + +## Troubleshooting + +- **"Provider isn't configured":** check both env vars are set; restart + to pick up changes. +- **"Refresh stalled":** check `last_error` on the connection row; usually + provider-side (network blip). Manual `Refresh now` from the UI clears + the backoff. +- **"Account mismatch":** user authorized a different account than the + existing connection. Disconnect first, then reconnect. + +## Known limitations + +- **Linear `accountInfo`** uses `https://api.linear.app/oauth/userinfo` + (Linear's OIDC userinfo endpoint). If Linear changes that endpoint, the + YAML at `server/oauth-providers/linear.yaml` will need to update or grow + a custom shape module. +- **Per-tenant rate limit** on `POST /oauth/connect/:providerId` is 50 + requests per 5 minutes (state-row flood guard). This is in addition to + the existing per-user limit. +- **Refresh worker leader-election** uses + `pg_try_advisory_xact_lock` inside a single transaction so the lock is + released automatically at COMMIT/ROLLBACK regardless of which pool + connection the underlying postgres-js client picked up. Multi-process + deployments coordinate naturally through the shared lock. +- **`mark-revoked` middleware** is wired in `app.ts` and reads a Bearer + run-JWT via `verifyLocalAgentJwt`. The endpoint returns 401 without a + valid JWT carrying an `oauth.connectionIds` claim, 403 when the claim + doesn't include the requested connection, 204 on success. +- **GitHub upstream revocation is best-effort.** GitHub's + `/applications/{client_id}/grant` endpoint requires `DELETE` and a + JSON body (`{"access_token": "..."}`), not RFC-7009's + `POST` + form-encoded shape that `revokeUpstreamToken` uses. The + upstream revoke call therefore always fails for GitHub — the local + disconnect cleanup path swallows the error and proceeds, so the + user's local state ends up correct, but the GitHub grant remains + valid until natural expiry or until the user revokes it via the + GitHub UI. A follow-up PR will add a per-provider `revokeStyle` + field to handle non-RFC-7009 providers. diff --git a/docs/superpowers/plans/2026-05-09-oauth-backbone-plan.md b/docs/superpowers/plans/2026-05-09-oauth-backbone-plan.md new file mode 100644 index 00000000000..da53db02d80 --- /dev/null +++ b/docs/superpowers/plans/2026-05-09-oauth-backbone-plan.md @@ -0,0 +1,5964 @@ +# OAuth Backbone Implementation Plan + +> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task.

OAuth flow handler routes generate PKCE state, exchange codes, persist tokens as new `company_secret_versions` rows, and expose connections via `/api/companies/:companyId/oauth/...`.

OAuth secrets do not need a separate `kind` value because the FKs from `oauth_connections.access_token_secret_id` / `.refresh_token_secret_id` already discriminate them. Task 2 is a no-op; **skip it**. Spec §9.4 has been amended accordingly. +- **Tasks 20 and 23 follow-up.** Where the plan's draft code shows `secretService.persistSecret({ kind: "oauth_access_token", ... })`, the actual call uses the existing secret-creation API on `secretService` (likely `createCompanySecret(...)` plus `appendVersion(...)`). The implementer of these tasks must inspect `server/src/services/secrets.ts` for the real API and pass only the parameters that exist (no `kind`). The OAuth backbone reuses the existing secret pipeline as-is. +- **`initiated_by_user_id` is `text`, not `uuid`.** Better Auth uses string user IDs in this codebase; the column type was adapted in T1.

Context & Goals + +### 0.1 Problem + +Today, Paperclip agents that need to act in third-party services (GitHub, Notion, Slack, Linear, …) rely on operators creating personal access tokens by hand and storing them as opaque `company_secrets`. There is no interactive authorization flow, no token refresh, no UI affordance for users to "Connect to GitHub", and no provider-agnostic data model. As we expand the set of supported integrations, this scales linearly in operator toil and is the wrong primitive for cloud SaaS users who expect a "Connect" button. + +### 0.2 Decomposition + +The full request — "let users authorize Paperclip to act on their behalf in third-party services" — naturally splits into three independent sub-projects, each with its own spec cycle: + +| | Sub-project | Summary | +|---|---|---| +| **A** | **OAuth backbone (this spec)** | OAuth 2.1 + PKCE flow, per-tenant connection storage, refresh worker, plugin-extensible provider registry. The credential layer that everything else consumes. | +| B | Inbound MCP integration | Per-connection MCP server attached to agent runtimes — turns an "active connection" into "tools the agent can call". Requires (A). | +| C | SDK aggregator plugin | Optional Composio/Nango-style fallback plugin that wraps a third-party aggregator's catalog. Requires (A). | + +Doing (A) first means (B) and (C) become small, focused additions rather than entangled rewrites. + +### 0.3 Goals for v1 of (A) + +1. **Cloud + self-hosted parity** — same code path, behavior differs only via env config. Operators of self-hosted instances configure their own OAuth apps; cloud ships defaults. +2. **5–10 launch providers** — GitHub, Notion, Slack, Linear, Atlassian, Google Workspace, Microsoft Graph (and any subset operators choose to enable). +3. **Per-company connections, single connection per provider.** Multi-account-per-company is a known v2 ask. +4. **Plugin SDK extensibility** — third parties can ship their own provider definitions. +5. **File/directory-based config** — adding a provider should not require a DB migration. +6. **Compatibility with the existing secrets pipeline** — tokens are "secrets with a refresh policy". The runtime never gets a new token-fetching API. + +### 0.4 Non-goals + +- Inbound MCP integration (sub-project B). +- SDK aggregator integration (sub-project C). +- Multi-account-per-company connections. +- Per-user (vs per-company) connections. +- DPoP / mTLS / token introspection / device flow / client_credentials. +- Real-provider integration tests in CI. + +--- + +## 1.

Refresh Strategy + +Two cooperating paths: a proactive worker, and a lazy refresh inside the resolver. + +### 5.1 Proactive worker + +**Schedule:** every 60s, single-instance via the existing `pg_try_advisory_lock` leader-election pattern. + +**Selection** runs in two passes — a cheap unfiltered scan to get candidates, then per-row backoff filtering in TS. The two-pass approach avoids defining a SQL stored proc for `backoffWindow` (whose definition lives in TS, Section 5.2): + +```sql +SELECT id, refresh_attempt_count, last_error_at +FROM oauth_connections +WHERE status = 'active' + AND refresh_token_secret_id IS NOT NULL + AND access_token_expires_at IS NOT NULL + AND access_token_expires_at < now() + interval '5 minutes' +ORDER BY access_token_expires_at ASC +LIMIT 100 +FOR UPDATE SKIP LOCKED; +``` + +Worker then drops rows where `last_error_at != null AND last_error_at + backoffWindow(refresh_attempt_count) > now()`. The cap of 100 candidates means the per-row filter cost is negligible. + +Per-row sequential refresh: +1. Decrypt latest refresh token. +2. POST to provider's token endpoint per Section 4. +3. On 2xx: write new `company_secret_versions` for access (and refresh if rotated), update row, clear `last_error*`, reset `refresh_attempt_count`. +4. On 4xx with `invalid_grant`/`invalid_token`: status → `revoked`. No retry. +5. On 5xx/network: increment `refresh_attempt_count`, write `last_error*`. Status stays `active` until `access_token_expires_at` passes; then flips to `expired`. + +### 5.2 Backoff + +```ts +function backoffWindow(attempts: number): Interval { + const seconds = Math.min(2 ** attempts * 30, 3600); // 30s … 1h cap + return Interval.fromSeconds(seconds); +} +``` + +Five consecutive failures → row stops being scheduled. Manual `POST /:id/refresh` or successful lazy refresh re-arms it. + +### 5.3 Lazy refresh inside the resolver + +Triggered when `access_token_expires_at < now() + 60s`: + +1. `SELECT … FOR UPDATE SKIP LOCKED` the row. If we lose the lock, poll `last_refreshed_at` for up to 2s. +2. Otherwise run the same refresh body as the worker. +3. On success, return freshly written plaintext. +4. On failure with a still-valid token, return the old token; otherwise dispatch fails with `oauth_refresh_failed`. + +The 60s window must exceed worst-case clock skew between replica and provider. + +### 5.4 Concurrency invariants + +- **Single in-flight refresh per row** — `FOR UPDATE SKIP LOCKED`. +- **Refresh-token rotation safety** — new refresh token is persisted in the same transaction as the new access token. Transaction rollback after rotation = `refresh_token_lost_after_rotation`, surfaces as `revoked` next tick. +- **Scope drift** — provider may return a different scope set than requested. Accept and store actual scopes; log WARN. Some providers (Google, Microsoft) silently drop user-declined scopes; failing closed would block valid logins. + +### 5.5 Revocation handling + +| Source | Trigger | +|---|---| +| Refresh | Provider returns `invalid_grant`/`invalid_token` | +| Runtime 401 | Agent-shim observes 401 from a known integration → calls `POST /api/oauth/connections/:id/mark-revoked` (run-JWT-authed, scoped to the connection ids the dispatch resolved) | +| Manual | `DELETE /api/oauth/connections/:id` | + +The runtime-401 path is the cheap substitute for provider webhooks (deferred from v1). + +### 5.6 Cleanup & metrics + +- **State sweeper** in the same worker: deletes `oauth_authorization_states` where `expires_at < now() - 1d`. +- **Metrics** (Prometheus, existing pattern): `oauth_refresh_total{provider,result}`, `oauth_refresh_duration_seconds{provider}`, `oauth_connections_by_status{provider,status}`. + +### 5.7 Out of v1 + +- Background pre-warming of newly created connections. +- Per-provider concurrency caps. + +--- + +## 6.
