supabase

supabase is a skill for Claude Code, Codex from mnlt/teleport. It costs 67 tokens per session (2,040 once invoked), scanned B, original, MIT.

A way to operate Supabase through its REST APIs, including project administration, database queries, authentication, file storage, realtime features, and Edge Functions. Supabase is a hosted backend platform for applications.

In plain words
What is it for?
Use it to list projects, retrieve API keys, read or write database tables, manage users and storage buckets, and work with supported project services when the required credentials are available.
Why use it?
It lets an agent perform supported Supabase operations without an MCP server. It also separates organization and project administration from requests to a specific project's services.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

supabase scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

> That covers the Management API PAT (`SUPABASE_ACCESS_TOKEN`). For per-project keys (`SUPABASE_URL` + `SUPABASE_ANON_KEY` / `SUPABASE_SERVICE_ROLE_KEY`), grab them from your project's dashboard → Settings → API — those

How it starts

The opening of the file, as written. The whole thing — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Supabase

Direct HTTP against Supabase's REST APIs — no MCP server required. Two distinct API surfaces on different hosts with different auth. Picking the wrong one is the single most common failure mode; internalize the split before sending any request.

Usage

  • Use for: Listing projects / fetching API keys, PostgREST table reads/writes, auth admin, storage bucket CRUD.
  • Skip for: Concept questions (RLS theory), direct psql over postgres://…, debugging user's supabase-js code, schema design.

Credentials check

# For Management API tasks
[ -n "$SUPABASE_ACCESS_TOKEN" ] && echo "SUPABASE_ACCESS_TOKEN: PRESENT" || echo "SUPABASE_ACCESS_TOKEN: MISSING"

# For Project REST tasks
for v in SUPABASE_URL SUPABASE_ANON_KEY SUPABASE_SERVICE_ROLE_KEY; do
  eval "val=\${$v}"
  [ -n "$val" ] && echo "$v: PRESENT" || echo "$v: MISSING"
done

Never echo these variable values directly — they would appear in the conversation transcript. Use only the boolean patterns above.

If the credentials for the task are MISSING, respond to the user with EXACTLY this message (do NOT paraphrase, do NOT suggest manual JSON edits for the management PAT):

I need your Supabase credentials. Run this in another terminal:

teleport-setup add-key supabase

That covers the Management API PAT (SUPABASE_ACCESS_TOKEN). For per-project keys (SUPABASE_URL + SUPABASE_ANON_KEY / SUPABASE_SERVICE_ROLE_KEY), grab them from your project's dashboard → Settings → API — those still need to be added to ~/.claude/settings.local.json manually (not yet covered by add-key).

Then restart Claude Code (/exit, then claude) and ask me again.

Do NOT suggest editing ~/.claude/settings.local.json manually for the management PAT. teleport-setup add-key supabase handles it safely with backup + masked input. Stop execution until the user has run the command and restarted.

The two-surface split — read this first

Surface Base URL Auth header(s) Env vars
Management API https://api.supabase.com/v1/... Authorization: Bearer $SUPABASE_ACCESS_TOKEN SUPABASE_ACCESS_TOKEN (personal access token)
Per-project REST $SUPABASE_URL/rest/v1/... Both: apikey: $KEY AND Authorization: Bearer $KEY (same value in both) SUPABASE_URL + SUPABASE_ANON_KEY or SUPABASE_SERVICE_ROLE_KEY
Per-project Auth $SUPABASE_URL/auth/v1/... Same two-header pattern Same as REST
Per-project Storage $SUPABASE_URL/storage/v1/... Same two-header pattern Same as REST

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

supabase is a skill published in the GitHub repository mnlt/teleport (9 stars, last pushed 4mo ago), licensed MIT. It adds 67 tokens to every session and 2,040 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 2 findings (reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
