Tools Supabase exposes

SUPABASE_ALPHA_CREATE_API_KEY

Create project api key

Creates a 'publishable' or 'secret' API key for an existing Supabase project, optionally with a description; 'secret' keys can have customized JWT templates.

SUPABASE_ALPHA_DELETE_API_KEY

Delete an API key from the project

Permanently deletes a specific API key (identified by `id`) from a Supabase project (identified by `ref`), revoking its access.

SUPABASE_ALPHA_DELETE_THIRD_PARTY_AUTH_INTEGRATION

Delete third party auth config

Removes a third-party authentication provider (e.g., Google, GitHub) from a Supabase project's configuration; this immediately prevents users from logging in via that method.

SUPABASE_ALPHA_GET_THIRD_PARTY_INTEGRATION

Get a third-party integration

Retrieves the detailed configuration for a specific third-party authentication (TPA) provider, identified by `tpa_id`, within an existing Supabase project specified by `ref`.

SUPABASE_ALPHA_LIST_THIRD_PARTY_AUTH_INTEGRATIONS

List third-party auth integrations for project

Lists all configured third-party authentication provider integrations for an existing Supabase project (using its `ref`), suitable for read-only auditing or verifying current authentication settings.

SUPABASE_ALPHA_UPDATE_API_KEY

Update an API key for the project

Updates an existing Supabase project API key's `description` and/or `secret_jwt_template` (which defines its `role`); does not regenerate the key string.

SUPABASE_APPLY_A_MIGRATION

Apply a database migration

Tool to apply database migrations to a Supabase project. Use when you need to execute SQL schema changes, create tables, alter columns, or run other DDL/DML operations as part of a tracked migration. This is a Beta feature in the Supabase Management API.

SUPABASE_BETA_ACTIVATE_CUSTOM_HOSTNAME

Beta activate custom hostname for project

Activates a previously configured custom hostname for a Supabase project, assuming DNS settings are verified externally.
