feat(mercury): keep the seven API tokens alive and report which survived - #178
chitcommit wants to merge 1 commit into
Conversation
Mercury deletes an API token after any 45-day period with no API call (docs.mercury.com/docs/api-token-security-policies). ChittyFinance had no outbound Mercury client at all — not one reference to api.mercury.com — so the seven per-entity tokens have been idle since they were provisioned and some are probably already gone. The keepalive is therefore also the liveness probe: its first run is the inventory. One read-only GET https://api.mercury.com/api/v1/accounts?limit=1 per entity, on the existing 09:00 UTC cron. No new scheduled trigger, so no new recurring spend. No write endpoint is ever called. Three states, not two. A 401 is a successful probe with a negative result, so alive (2xx), dead (401/403) and indeterminate (timeout, 429, 5xx, unexpected status, absent binding) are classified separately by a pure function — conflating "the token is dead" with "we could not reach Mercury" would make the probe useless. Mercury's errors.errorCode is carried alongside the status so a 403 from an IP-allowlist rejection stays distinguishable from a revoked token. The seven bindings are declared as secrets_store_secrets against the account-level store e914522471964c3c8cf1e601770edcc3, the same store and binding names CHITTYOS/chittysecrets/wrangler.json uses. Because the store is account-level this needs no ChittySecrets broker in the path. Bindings do not inherit into env blocks, so top level and all three envs carry them in both configs; deploy/system-wrangler.jsonc is the live deploy path and the root config is the Workers Builds one (#111), mirrored to stop them drifting further. Credential handling: bindings are referenced by name, .get() happens at the call site, and the value exists only inside the Authorization header. Nothing logged, returned or persisted holds a token. The 2xx body is cancelled unread because /accounts carries account and routing numbers; only non-2xx bodies are parsed, and only for errorCode — never Mercury's prose message. Recorded in FINANCE_KV rather than a new Neon table: the only vaguely related existing table, integrations, is tenant-FK'd and these bindings have no tenant mapping; a new table means a destructive drizzle-kit push for seven rows a day; and KV is already this repo's operational-state store (sessions, inbound-email index, Wave webhook secrets). Token liveness is rotation state, which the operator KV policy allows. Per-token and latest-run keys carry no TTL. GET /api/v1/mercury-tokens reads the last run; POST .../probe runs it now, so liveness is readable without waiting for 09:00 UTC. Both are behind serviceAuth: the /api/v1/* neighbours are all public, but an open endpoint enumerating which banking tokens are alive is an information leak. The two cron jobs are isolated with allSettled — processLeaseExpirations throws outright on an unbound DATABASE_URL and must not be able to skip the keepalive.

Both the scheduled job and the manual probe send all seven requests directly to api.mercury.com, bypassing the repository's required Mercury proxy and moving credential/network-policy handling into this Worker. The existing account reader in server/routes/mercury.ts demonstrates the configured CHITTYCONNECT_API_BASE path; route these probes through ChittyConnect as well.

When a valid read/write token is rejected because the Worker source IP is not allowlisted, the preceding comment acknowledges that Mercury may return 403, yet this branch reports the token as dead and increments the dead count. Mercury requires IP allowlisting for read/write tokens (token policy), so classify 403 as indeterminate unless its error code conclusively identifies a revoked/deleted token; otherwise the inventory can tell operators to replace a surviving credential.

If any kv.put rejects because of a KV outage, quota, or binding problem, allSettled resolves and its results are discarded, so the cron logs completion and the POST endpoint returns status: ok even when run:latest remains stale or the per-token records are only partially updated. Continue attempting every write, but inspect the settlements and propagate or report failures before claiming that the run was recorded.

The staging and production blocks in both Wrangler configs use the same FINANCE_KV namespace and both run this cron at 09:00 UTC, but this new latest-run key is global. Consequently, a staging cron or manual probe can overwrite the report returned by the production endpoint—especially when the two deployments have different code, bindings, or network outcomes—so the production inventory may actually describe staging. Include the deployment environment in these keys or give staging a separate namespace.

The live deploy configuration binds the same account-level store and the same seven Mercury secret names into dev, staging, and production, while the non-production environments also have active cron triggers. Deploying either non-production Worker therefore grants its code access to every real banking credential and makes it probe live organizations daily, substantially expanding the exposure of production financial data. Omit these bindings and the keepalive cron outside production, or use environment-specific test credentials.

Cloudflare Workers fetch redirect follow Authorization header cross-origin redirect documentation Fetch API
💡 Result:
Inspection citation: inspection_9aa6c3987446529c1f9284c758fe054c
**Cloudflare Workers differs from browser Fetch here.** With a Worker subrequest using `redirect: "follow"`, Cloudflare documents that it forwards **all request headers—including `Authorization`—to the redirect destination, even across hostnames or domains**. ([developers.cloudflare.com](https://developers.cloudflare.com/workers/runtime-apis/request/?utm_source=openai))
That differs from the Fetch Standard, which removes `Authorization` when a redirect crosses origins. ([fetch.spec.whatwg.org](https://fetch.spec.whatwg.org/?utm_source=openai))
To avoid sending credentials to a redirect destination, use `redirect: "manual"` and validate the `Location` yourself before making another request. Cloudflare notes that requests passed into the Worker from the client default to `manual`; the warning applies to Worker-made `fetch()` subrequests.

Sensitive Data Exposure
Reachability: External
Exploitability: Difficult
CWE: CWE-522 — Insufficiently Protected Credentials
Disable redirects for the credentialed probe. If Mercury returns a redirect, Cloudflare Workers follows it by default and forwards Authorization to the destination, including across domains. That can disclose the token. The final response can also mark the redirected host’s 2xx response as alive or its 401/403 response as dead.
Set redirect: 'manual'. The existing unexpected-status branch classifies a returned 3xx response as indeterminate.

Reject the probe when FINANCE_KV is absent.
If FINANCE_KV is absent, the POST handler can return HTTP 200 with status: 'ok' even though keepaliveAndRecord skipped persistence. This contradicts the route’s stated record side effect, and the corresponding GET returns HTTP 500 instead of that report. Check for KV before running the probe.

Why
Mercury deletes an API token after any 45-day period with no API call — not expires, deletes (API token security policies: "Tokens inactive for any 45-day period face automatic deletion"; admins get 7 days' notice). ChittyFinance had no outbound Mercury client at all — zero references to
api.mercury.comanywhere in the tree — so the seven per-entity tokens have been idle since they were provisioned and some are probably already gone. Nobody knows which.The keepalive is therefore also the liveness probe. Its first run is the inventory.
What this does
One read-only
GET https://api.mercury.com/api/v1/accounts?limit=1per entity (getAccounts), on the existing0 9 * * *cron. No new scheduled trigger — a new one is new recurring spend, whichstartup-modegoverns. No write endpoint is ever called; the module has one URL constant and a test asserts all seven calls hit exactly it and nothing matchingsend-money|transaction|transfer.Three states, not two
A 401 is a successful probe with a negative result, not an error to swallow.
classifyProbeis a pure function over{status?, errorCode?, transportError?, bindingMissing?}:alivedeadindeterminatebinding_missingdeadis deliberately narrow — only where Mercury told us the token itself is unacceptable. Mercury'serrors.errorCode(noTokenInDB,noAuthTokenHeader, …) is captured alongside the status, so a 403 from an IP-allowlist rejection stays distinguishable from a revoked token rather than collapsing into "dead".binding_missingis its own reason because that is exactly what you'll see until this deploys — a Worker without the bindings must not report seven dead tokens.Egress finding — read-only probes are not IP-gated
The operator's static-IP concern does not apply to this probe. Mercury's own policy doc:
So if the seven were provisioned read-only, as the brief says, Worker egress is fine and the absence of a stable egress IP is irrelevant here. Corroborating: an unauthenticated
GET /api/v1/accountsfrom an arbitrary non-allowlisted IP reaches token validation and returns401 noAuthTokenHeader; with a bogus bearer,401 noTokenInDB. There is no network-layer IP gate in front of the API either way. If any token turns out to be read+write, the first run is the test: a 2xx proves reads aren't gated; a 401/403 whoseerrorCodeis IP-shaped proves they are — which is why the code is persisted and surfaced.Same doc: "Tokens that have higher permissions than they utilize in a 45-day window are automatically adjusted to the appropriate permission level" — downgraded to read-only. A read-only daily ping prevents deletion but does nothing to exercise write scope, so any read+write token among the seven will be auto-downgraded to read-only within 45 days of its last write, keepalive or not. Recovery requires minting a fresh token and performing a write inside the window; scopes cannot be changed after creation.
Consequence for the out-of-scope next piece:
PATCH /transaction/{id}will find read-only tokens unless it ships inside that window or the tokens are re-issued. That is a planning fact, not a defect in this PR.Durable record — KV, deliberately, not a new table
Stated rather than done silently, as asked:
integrationsis the only remotely related existing table and it does not fit:tenant_id uuid NOT NULL REFERENCES tenants(id). The seven tokens are keyed by Secrets Store binding name with no tenant mapping — rows would need an invented tenant.drizzle-kit push, which CLAUDE.md records as destructive and cutover-coordinated. Disproportionate for seven rows a day, and against the standing posture of not entrenching Postgres.FINANCE_KVis already this repo's operational-state store — sessions, the inbound-email index, Wave webhook secrets.Keys:

serviceAuth. This contradicts the brief's "auth-gated the way its neighbours are": the/api/v1/*neighbours (status,metrics,documentation) are all unauthenticated, so that instruction is unsatisfiable — an open endpoint enumerating which banking tokens are alive is the information leak the brief forbids. Same bearer gate as/api/admin, and deliberately notenantMiddleware(fail-closed since #144; these bindings are account-level and have no tenant) and nostorageMiddleware(no DB access).

The three-state classification was broken on purpose and watched to fail, twice.

Both jobs now run underPromise.allSettledand are reported independently.

Same reason for not editing it.git wtdid not symlinknode_modulesinto this worktree; it was absent and had to be linked by hand. Note: wrangler's custom build ranpnpm install --ignore-workspaceagainst that sharednode_modulesduring the first dry-run attempt. Verified afterwards that the main checkout'snode_modulesand.binshims are intact and the full suite passes — but a parallel session shares that directory, so the build-stripped config used for the real validation avoids repeating it.Not done, operator-gated
Not deployed. The probe has not run, so which tokens are actually alive is still unknown — that answer needs

Mercury's 7-day pre-deletion warning emails may already be in the operator's inbox and would name the affected tokens sooner than a deploy.🤖 Generated with Claude Code

noTokenInDBis ambiguous — do not re-provision on it alone. The curl evidence above shows a malformed bearer returns the identical401 noTokenInDBas a deleted token. Mercury's getAccounts reference says the bearer must include thesecret-token:prefix; nothing inCHITTYOS/chittysecrets/srcprepends or strips it, so the stored shape is unverified and this module passes the value through as-is. If the first run reports 7/7noTokenInDB, check one stored value's shape operator-side before concluding all seven are deleted — a missing prefix would look exactly like total deletion.The deploying API token needs Secrets Store read scope.
wrangler deploywithsecrets_store_secretsfails outright without it, and--dry-rundoes not test account permissions — so a green dry-run is not evidence the real deploy will bind.

This PR changes no dependencies —package.jsonandpnpm-lock.yamlare untouched — and the gate passed onmainatcefe04con 2026-09-28, so the advisory was published since. It will block every PR in this repo until an override lands; fixing it is a separate change, not something to smuggle into a Mercury keepalive.Watch item:
