Vercel Remote

vercel-remote

Project-scoped CLI that wraps the Vercel REST API into a read-first, JSON-output overview tool. Stdlib-only Python 3 (no pip installs, no venvs). Designed for agent-driven incident triage — one call returns the full project/deployments/domains/env-names picture so you don't burn tool calls chaining per-resource requests.

Lives at ${CLAUDE_SKILL_DIR}/../../bin/vercel-remote; the plugin auto-adds bin/ to PATH, so just run vercel-remote ....

Prerequisites

• VERCEL_TOKEN set (project .env / .env.local or shell env). Get one at https://vercel.com/account/tokens.
• Optional: VERCEL_TEAM_ID for team-scoped projects. Every API call appends ?teamId=… when set.
• Optional: VERCEL_PROJECT to omit --project on every call.

The CLI bails with a clear missing-config message if VERCEL_TOKEN is absent.

When to reach for this

• User asks "what's happening on " → run overview --project --pretty. One call → project info + recent deployments (with commit metadata) + domain health + env var NAMES + top-level warnings.
• User asks "why is prod broken" → run deployments list --project --state error --limit 5 then logs --errors-only.
• User asks "what env vars does have" → run env list --project . Names only — values never touch output.
• User asks "trigger a deploy" → run deployments trigger --hook-url --wait. Waits up to 15 min for build completion.
• User asks "is my domain verified" → run domains list --project or domains verify --project --wait.

All list/show commands emit JSON to stdout. Use --pretty for indentation.

Every payload carries a top-level tool: {name, version} field so agents can self-diagnose version drift from the output alone. Run vercel-remote --version to check the installed version directly.

Offloading large responses with --output

Vercel responses get large fast — logs on a chatty deployment, overview with high --limit, deployments list across many deployments. Pulling all of that through the model's context is wasteful when you only need a slice.

Pass --output before the subcommand (it's a top-level flag, like --pretty):

vercel-remote --output /tmp/logs.json logs my-app-xyz.vercel.app --since 24h
vercel-remote --output /tmp/deps.json deployments list --project my-app --limit 50

Instead of printing the full payload, stdout returns a compact envelope:

{
  "tool": {"name": "vercel-remote", "version": "..."},
  "payloadPath": "/tmp/logs.json",
  "bytes": 48320,
  "fileLineCount": 1204,
  "payloadKeys": ["deployment", "entries"],
  "payloadShape": {
    "deployment": {"type": "string", "length": 24},
    "entries": {"type": "list", "length": 412,
      "sample": {"type": "dict", "keys": 5,
        "shape": {"level": {"type": "string", "length": 5},
                  "message": {"type": "string", "length": 187},
                  "timestamp": {"type": "number"}}}}
  }
}

How to act on it:

1. Check payloadShape to see where the data lives and how much there is. In the example above, the agent immediately knows there are 412 log entries with {level, message, timestamp} fields — no second call needed to discover shape.
2. Use Read with offset/limit to pull the slice you need. fileLineCount is the upper bound.
3. For list-shaped responses (projects list, deployments list), the envelope has payloadType: "list" + payloadLength + sampleShape describing the first item.

--shape-depth controls recursion depth. Default is 3 (two layers deep — surfaces patterns like deployments[0].meta). Drop to 1 for a minimal envelope.

When NOT to use --output: small responses (projects resolve, env list — NAMES are already tiny), or when you need the data in the same turn to act on. The envelope points at the file; it doesn't carry the data.

Piping to jq

Output is JSON-first, so pipe freely to jq for focused extraction:

# Failing deployments only
vercel-remote overview --project my-app | jq '.deployments[] | select(.state == "ERROR")'

# Unverified domain names
vercel-remote domains list --project my-app | jq '.[] | select(.verified == false) | .name'

# Env var names (no values) as a flat list
vercel-remote env list --project my-app --env production | jq -r '.names[]'

Design rules (agent-plus patterns)

1. Aggregate server-side. overview returns project + deployments + domains + env names in one call — you don't chain four requests.
2. Resolve by name. Pass --project my-app, not prj_xxxxxxxxxxxxxxxx. The CLI resolves internally via /v9/projects/{idOrName}.
3. --wait on every async flow. deployments trigger, domains verify, env set/remove support --wait with per-command sensible timeouts (15m / 5m / 30s). On timeout: non-zero exit with partial JSON including the last-known state.
4. --json is the default. No human-prose output paths. Pipe to jq freely.
5. Zero env-value leakage. env list returns NAMES only. Every API response walks through _scrub() before emission, which masks password, token, githubToken, value, secret, encryptedValue, and related keys. A canary-value test (test/test_vercel_remote.py) asserts a known secret substring never appears in any output path.

Config precedence (highest first)

1. --token / --team CLI flags
2. --env-file if passed
3. .env.local / .env walked up from cwd (closest wins)
4. Shell env

Only VERCEL_* prefixed vars are picked up.

Safety

• Read-only by default. Write commands (env set, env remove, deployments trigger) are explicit subcommands.
• No deployments trigger via the file-upload path. The command uses Vercel Deploy Hooks (pre-configured webhook URLs, stored as a project secret) — see https://vercel.com/docs/deployments/deploy-hooks. Pass the hook URL via --hook-url.
• Team scoping is mandatory when VERCEL_TEAM_ID is set. Every API call appends ?teamId=…. Without it, team-scoped resources return 404.

Error message contract

Every error path emits problem + cause + fix + link:

• Missing token → "Set in project .env or .env.local (keys prefixed VERCEL_), or ~/.claude/settings.json. Get one: https://vercel.com/account/tokens"
• 401 → "Token invalid or expired. Regenerate: https://vercel.com/account/tokens"
• 403 → "Token lacks required scope. Regenerate with appropriate scope."
• 429 → "Rate-limited by Vercel API. Retry after a few seconds." (Retry-After is honoured automatically; you only see this on exhausted retries.)
• 404 with team scope → notes the team-ID prefix so you can verify VERCEL_TEAM_ID.

What it doesn't do

Deliberately out of scope for v1:

• Team / user CRUD (team scoping is fully supported via VERCEL_TEAM_ID; only team management is deferred).
• Billing and invoices.
• Edge Config authoring.
• Framework-specific build logic.

Use the vercel CLI or the dashboard for those. This plugin is read-first operational triage plus the minimum write surface needed by agents (env set/remove, deploy hook trigger).

When NOT to use this — fall back to the vercel CLI or the Vercel API directly

This wrapper's scope is deliberately narrow: projects (list/resolve), overview, deployments (list/show/trigger via Deploy Hook), logs, domains (list/verify), and env (list NAMES / set / remove). Anything outside that surface is not here and won't be — use the vercel CLI (already authed on the user's machine) or curl https://api.vercel.com/... with Authorization: Bearer $VERCEL_TOKEN instead.

Specific cases where you should skip vercel-remote and go straight to vercel or the raw API:

• Creating, renaming, or deleting a project, or configuring its Git integration / framework preset / build-and-output settings. → vercel project add, vercel project rm, or POST/PATCH/DELETE /v9/projects[/{id}]. vercel-remote only reads and resolves projects.
• DNS records CRUD, domain transfers, or buying a domain. domains list/verify check project-attached domains; they don't touch the account-level domain registry. → vercel domains ... or /v4/domains, /v2/domains/{domain}/records.
• Edge Config, Blob, KV/Redis, or Postgres storage (reading/writing items, creating stores, rotating tokens). → vercel env pull + the relevant storage SDK, or the /v1/edge-config/*, /v1/blob/*, storage integration endpoints directly.
• Cron jobs, firewall rules, deployment protection, preview comments, web analytics config, log drains, integrations/marketplace, team/user management, billing/invoices. None of these are wrapped. → dashboard, vercel CLI, or the corresponding /v1/... endpoint.
• Deploying from local files (not via a pre-configured Deploy Hook). deployments trigger only fires Deploy Hook URLs. → vercel deploy / vercel --prod, or POST /v13/deployments with a file-upload payload.
• Tailing logs live / runtime (non-build) logs. logs is a one-shot snapshot of build/function logs for a specific deployment. → vercel logs --follow for a live tail, or the runtime logs drain.

Don't get stuck in a loop. If a vercel-remote command errors with "unknown subcommand" / "not supported", or the user's request obviously needs a write or resource the wrapper doesn't expose, immediately switch to vercel or curl against api.vercel.com rather than re-trying vercel-remote with different flags. The wrapper exists to make reading faster and safer, not to replace the CLI or the REST API.
