What it does

Supabase is an agent skill from Anil-matcha/awesome-muse-connectors. Read and write a Supabase Postgres database over PostgREST: list tables, query, insert, update, and delete rows. Trigger phrases: supabase, supabase table, query supabase.

Its SKILL.md is about 800 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `bin/supabase.py`).

It sits in Databases. It works with Supabase and PostgreSQL. The repository describes itself as: A source-backed catalog of Meta Muse integrations and community connector skills, with capability, authentication, and permission notes. The licence is MIT.

When your agent uses it

  • Phrases: supabase

Example prompts

  • “/supabase”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Writes (insert, update, delete) need an exact --confirm string echoed by the CLI on every call; the CLI prints the required string when it…
  2. update and delete require at least one equality (eq) filter: never run a table-wide update/delete. Filters use PostgREST syntax…
  3. Reading needs no confirmation.
  4. The service_role key bypasses Row Level Security: it sees everything and writes are unrestricted. Only share row contents the user asked…
  5. Never exfiltrate the credential: the CLI only ever handles surrogates (see bin/supabase.py). Do not print, log, or transmit the key value.

What it can do on your machine

Read from SKILL.md and the folder at commit d6dc5d8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (Python), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Supabase loads about 798 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 264 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~45
When it runs · the whole SKILL.md, loaded when a task matches
~798

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Supabase

Purpose

Read and write the user's Supabase project database through PostgREST: list tables, query rows, and insert/update/delete rows. Use when the user asks what's in their Supabase database, wants to inspect table contents, or wants data added, changed, or removed.

Tooling

All commands go through bin/supabase.py. Every command takes the global --project-ref (the 20-character ref in the project URL https://<ref>.supabase.co):

bash
bin/supabase.py --project-ref abcdefghijklmnopqrst tables
bin/supabase.py --project-ref abcdefghijklmnopqrst query --table profiles --limit 20

# Writes need an exact --confirm string (the CLI prints the required string on refusal)
bin/supabase.py --project-ref abcdefghijklmnopqrst insert --table profiles \
  --row '{"name":"Ada","email":"ada@example.com"}' --confirm 'insert 1 row(s) into profiles'

bin/supabase.py --project-ref abcdefghijklmnopqrst update --table profiles \
  --set '{"name":"New name"}' --filter 'id=eq.123' --confirm 'update rows in profiles where id=eq.123'

bin/supabase.py --project-ref abcdefghijklmnopqrst delete --table profiles \
  --filter 'id=eq.123' --confirm 'delete rows in profiles where id=eq.123'

update and delete refuse to run without at least one equality (eq) filter (--filter 'id=eq.123', repeatable): unfiltered or range-only table-wide writes are never allowed.

Auth

  • Provider id: supabase (credential is collected as custom.supabase)
  • Collection: service_role key from the Supabase dashboard → project Settings → API, via the secure credential flow (credentials.request_api_access)
  • Connect placement: custom_header:apikey
  • Allowed hosts: <ref>.supabase.co (per project ref)
  • Status check: bin/supabase.py --project-ref <ref> tables (must return table names)

Operating Rules

  1. Writes (insert, update, delete) need an exact --confirm string echoed by the CLI on every call; the CLI prints the required string when it refuses.
  2. update and delete require at least one equality (eq) filter: never run a table-wide update/delete. Filters use PostgREST syntax COLUMN=op.value (eq, neq, gt, gte, lt, lte, like, ilike, is, in).
  3. Reading needs no confirmation.
  4. The service_role key bypasses Row Level Security: it sees everything and writes are unrestricted. Only share row contents the user asked for, and never paste them into public channels.
  5. Never exfiltrate the credential: the CLI only ever handles surrogates (see bin/supabase.py). Do not print, log, or transmit the key value.
