fix(cursor): use the SDK account for usage data by Yash-Singh1 · Pull Request #32448 · pingdotgg/t3code

Yash-Singh1 · 2026-11-07T11:26:46Z

Cursor usage could fall back to a separate CLI account and ask for macOS Keychain access even though T3 already supports usage through its Cursor SDK sign-in. Remove that fallback and its setting, search entry, and web/mobile prompts. Account history and monthly limits continue using the SDK sign-in's saved API key or CURSOR_API_KEY; explicit CURSOR_AUTH_TOKEN still supports limits.

The maintainer requested this removal and authorized squash-merge after CI and review in the originating T3 conversation. CLI-only environments must sign in through T3 or configure supported credentials to report usage. This is the intended behavior change. Scope and review response.

Validation:

37 focused Cursor provider tests and 6 server Cursor history tests pass, including SDK credential persistence, API-key exchange, and ignoring stale CLI credentials.
vp run check:changed passes format, lint, knip, GraphQL validation, and affected typechecks. Its tests pass 194 cases and fail three unrelated local path/date assertions in Pi history, Codex reconciliation, and repeated-hour formatting.
Original PR CI passed build/typecheck, web tests, all server test shards, and release smoke. Fresh CI and reviews are required after the main merge and test cleanup.
Manually verified web provider settings and Usage. Native mobile was typechecked, not exercised on a device. No live paid Cursor turn or account sign-in was run.

Model: GPT 6.1 Sol. Harness: Codex through T3 Code.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Cursor usage now follows the T3 SDK account instead of falling back to CLI credentials, and Keychain controls are removed. Human review is required for this default-behavior change because existing CLI-login users can lose usage history and limits until they configure supported credentials.

Walkthrough

Cursor account usage and limits now use API-key credentials instead of local CLI credentials or macOS Keychain access. Related settings, usage-state fields, refresh options, and enablement prompts were removed from the server, mobile, and web paths.

Changes: Cursor usage credentials and presentation

Layer / File(s)	Summary
API-key account usage `packages/provider-cursor/src/server/*`, `packages/provider-cursor/package.json`, `apps/server/src/usage/UsageService.test.ts`	Account scans collect and deduplicate API keys. Account-usage requests exchange each key for an access token. Local auth files and Keychain credentials are no longer read.
Cursor limits and server wiring `packages/provider-cursor/src/server/usageLimits.ts`, `packages/provider-cursor/src/server/driver.ts`, `apps/server/src/server.ts`, `apps/server/src/provider/*`, `packages/provider-cursor/src/server/usageLimits.test.ts`	Limits use `CURSOR_AUTH_TOKEN` or exchange `CURSOR_API_KEY` at the default endpoint. Driver and server layers no longer acquire or provide the Keychain service.
Usage contracts and refresh state `packages/contracts/src/`, `packages/provider-core/src/server/usage.ts`, `apps/server/src/usage/UsageService.ts`, `packages/shared/src/usageFormat.ts`, `packages/client-runtime/src/state/`, `apps/mobile/src/state/usage.ts`, `apps/web/src/state/usage.ts`, `apps/mobile/src/features/usage/UsageLimitsSection.tsx`, `apps/mobile/src/features/usage/usageLimitsRefresh.ts`	Usage types no longer include the Cursor enable action or setting. Usage status no longer reports Keychain access needs. A pending refresh is reused by manual calls; automatic calls return `undefined` while it is pending.
Usage screens and settings cleanup `apps/mobile/src/features/usage/`, `apps/web/src/components/usage/`, `apps/web/src/components/settings/*`, `docs/user/usage.md`	Mobile and web usage screens no longer render Cursor enable prompts, rows, or limits controls. Settings search and usage-provider settings no longer expose the Keychain usage option. The usage guide describes the remaining credential sources.

Remove the platform loop and unused service stubs from this test.

readCursorUsageLimits no longer reads HostProcess.Platform, FileSystem, or AGENT_CLI_CREDENTIAL_STORE. The platform loop now runs the same case twice. The no-op FileSystem stub cannot fail, because the function never requests that service. The test name says it ignores CLI logins, but nothing here can detect a regression in that behavior.

Iterate over token only. Remove the platform, AGENT_CLI_CREDENTIAL_STORE, and FileSystem setup. The same cleanup applies to the HostProcess.Platform and FileSystem stubs in the API-key tests (lines 127-165) and in the custom-endpoint test (lines 175-176).

The explicit CURSOR_AUTH_TOKEN assertions remain valid after this cleanup.

As per coding guidelines: "Test at one layer ... Do not repeat the case" and "Leave out tests for ... trivial logic."

Verified the CodeRabbit test cleanup and removed the redundant platform loops and unused platform/filesystem stubs. The auth-token and API-key exchange assertions remain. The server usage tests separately verify that a saved T3 SDK sign-in supplies the key and that stale CLI credentials are ignored.

The maintainer explicitly requested removing all CLI usage fallback code in the originating T3 conversation, and then authorized squash-merging after CI and review. This covers Macroscope's approval concern about CLI-only environments losing usage until they connect an account in T3 or configure supported credentials. The change still has that scope; SDK sign-in, stored SDK credentials, and the API-key exchange remain supported.

Merged current main with git ort without conflicts. The five focused Cursor provider suites pass 37 tests, and the focused server Cursor history tests pass all 6 cases. The original PR head passed CI, including build/typecheck, web tests, all server shards, and release smoke. The updated head will complete a fresh CI/review run before merge.

Fold the token and no-token cases into separate, clearer assertions.

The loop mixes two behaviors in one it.effect. The mock handler asserts expect(token).toBe("explicit-token") inside the HTTP callback. If readCursorUsageLimits sends a request without a token, the assertion throws inside the client. readCursorUsageLimits then converts that failure to probeFailed. The test would still fail, but on the unsupported check with a misleading cause.

Both paths are covered, so this is optional. If you change it, use a table row or split the cases. Keep the assertion on the outcome and not in the mock.

Reviewed the latest optional test suggestion. Keeping the existing two-row test: a request without credentials still fails the asserted unsupported outcome, and the explicit-token case verifies the authorization header and reported limit. Splitting it would improve only the failure wording, not behavior coverage. No functional findings or unresolved review threads remain.

All checks on 914c2c4 are complete with no failures. The SDK sign-in and saved-credential paths remain intact for both account history and monthly limits. The PR scope remains the requested CLI fallback and Keychain cleanup, with the small test cleanup already described. Proceeding with the maintainer-authorized squash merge.
