Description

Implements the Prisma integration requested in #763, covering all 22 operations listed on the OSS claim using the Prisma Management API (https://api.prisma.io/v1) plus direct Postgres wire-protocol access for query/command/schema-inspection.

Endpoint surface (nested domains):

  • workspaces.list — list workspaces (cursor pagination)
  • projects.create / get / list / delete / transfer — create with createDatabase+region, fetch, list with cursor/limit, delete (destructive, irreversible), transfer to another workspace via recipientAccessToken (partner flow)
  • databases.create / get / list / delete / getUsage / inspectSchema — create DB in a project, fetch, list, delete (destructive, irreversible), per-DB usage metrics over startDate/endDate, and information-schema schema inspection (tables, columns, types, nullable, defaults, foreign keys)
  • sql.query / sql.execute — direct Postgres over TLS: read-only SELECT (sql.query) with a hard guard rejecting any non-SELECT statement, and parameterized write commands (INSERT/UPDATE/DELETE/DDL) via sql.execute
  • connections.create / list / delete — create a connection (ready-to-use connection string), list, revoke (destructive, irreversible)
  • backups.list / backups.restore — list backups for a database, restore a backup onto a target database (destructive, async)
  • regions.list / listPostgres — all regions across products (optional product filter) and Prisma Postgres regions with availability
  • integrations.list — workspace integrations (OAuth clients, granted scopes)

Auth: API-key (Bearer service token) and OAuth 2.0, matching the two auth types in the claim. Defaults to API key; OAuth access tokens used for the workspace-integration and project-transfer flows.

Implementation notes:

  • zod input/output schemas on every endpoint (R7) — path-param validation, cursor/limit pagination on all list ops, shaped output schemas for the direct-Postgres operations
  • Errors routed through error-handlers.ts (429 rate-limit with Retry-After, auth 401, DEFAULT last)
  • Destructive operations flagged irreversible and mapped to the destructive risk level
  • Offline api.test.ts fixtures with real assertions for every operation; pg and @types/pg added as dependencies (existing 8.21.0 in the lockfile)
  • Added pnpm run validate:plugins — prisma package passes (pre-existing convex/kaggle/openrouter failures elsewhere are unrelated)

Checklist

  • I have run pnpm lint and all checks pass
  • I have run pnpm typecheck and there are no TypeScript errors
  • I have run pnpm build and all packages build successfully
  • I have run pnpm test and all tests pass
  • I have added or updated tests where applicable
  • I have added or updated necessary documentation

Screenshots / Demos

Demo video: https://www.loom.com/share/3f1f58844edf4c0f9dff16b6dd6befe9

Additional Notes

  • Direct-Postgres operations connect over TLS to the connection returned by the connection/API-key ops (host, port, user, password, database). sql.query is read-only by design: the guard rejects anything that is not a SELECT (including WITH … INSERT mutations and multiple statements), so read paths can never mutate data.
  • backups.restore is in-place/async per the Management API (POST /databases/{targetDatabaseId}/restore); completion is observed through database status.
  • Only packages/prisma/**, the prisma registration in packages/corsair/core/constants.ts, and pnpm-lock.yaml are touched (R1).

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 19f53

The PR currently rejects valid backup-restore responses and allows certain aliased or qualified SQL function calls to bypass the read-only guard, which could cause failed restores, stalled connections, or unintended database changes; a package typecheck failure is also reported. Merge should be blocked until these issues are fixed.

Inline comments:
In `@packages/prisma/endpoints/sql.ts`:
- Around line 41-47: Update executePostgresQuery’s read-only path used by
queryDatabase to enforce exactly one side-effect-free SELECT before
client.query, rejecting constructs such as SELECT INTO and multiple statements
containing writes; alternatively, execute the query within a database-enforced
read-only transaction. Preserve normal behavior for valid single SELECT
statements.

In `@packages/prisma/index.ts`:
- Around line 91-94: Update the errorHandlers merge in the Prisma configuration
so custom handlers from options.errorHandlers are placed before DEFAULT, while
preserving custom overrides for built-in names and allowing new handlers to be
selected before DEFAULT’s catch-all match.

In `@packages/prisma/operations/sql.ts`:
- Around line 17-27: Update the executeDatabaseCommand operation’s riskLevel
from write to destructive, preserving its existing endpoint metadata and
dispatch behavior.

In `@packages/prisma/pg-client.ts`:
- Around line 58-67: Enable TLS certificate verification by default in the
Client configuration and the inspectPostgresSchema connection setup by changing
both sslRejectUnauthorized fallbacks to true, while preserving explicit
caller-provided values.
- Around line 69-79: Update both Client constructors in the PostgreSQL client
setup to configure explicit connectionTimeoutMillis and statement_timeout (or
query_timeout) values, ensuring connection establishment and both schema catalog
queries have bounded execution time. Preserve the existing connect, query,
result mapping, and cleanup flow.
- Around line 20-41: Harden the read-only boundary around isReadOnly and
assertReadOnlyQuery so SELECT expressions cannot invoke mutating functions and
multiple statements or transaction-control SQL cannot execute via the simple
protocol. Enforce PostgreSQL read-only transaction semantics, use the extended
protocol rather than default empty parameters, and ensure failures roll back
while successful queries commit only after completion.

In `@packages/prisma/endpoints/types.ts`:
- Around line 112-208: The documented Prisma resource schemas currently allow
empty objects; require a stable identifying field, normally id, in each of
PrismaApiKeySchema, PrismaDatabaseSchema, PrismaProjectSchema,
PrismaWorkspaceSchema, PrismaConnectionSchema, PrismaBackupSchema,
PrismaRegionSchema, and PrismaIntegrationSchema. Keep other fields optional and
use a resource-specific required field where id is not the appropriate stable
shape, so resourceOrList also rejects envelopes containing empty items.
- Around line 314-317: Update the schema construction around
PRISMA_REST_OUTPUT_SCHEMAS to register explicit response schemas for
restoreBackup, deleteProject, deleteDatabase, and deleteConnection, using an
empty-response schema for bodyless operations. Remove the z.unknown() fallback
and fail schema construction when any REST operation lacks a registration;
update the related test to assert this failure rather than accepting
z.unknown().

Comment thread packages/prisma/pg-client.ts Outdated
PostgreSQL treats comments as token separators, so 'name /*c*/ (' and 'name -- c\n(' are still function invocations. The read-only allowlist lookahead skipped only whitespace, letting unlisted side-effecting functions (pg_sleep, dblink_exec, ...) hide their '(' behind a comment. Add a skipSqlTrivia helper (whitespace + line comments + nested block comments, mirroring the main scanner) and use it for both the bare-word and quoted-identifier call-site checks, with regression tests for block/line/nested/mixed comment vectors and allowlisted-name allowances.

846-848: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Do not let client.end() replace the original error.

client.end() runs for every exit path, including a failed client.connect(). If it rejects, its rejection replaces the query error or the connection error, and the caller loses the actionable cause. Swallow the shutdown error.

121-129: 🎯 Functional Correctness | 🔵 Trivial | 💤 Low value

Reject non-finite numeric path parameters.

typeof value === 'number' accepts NaN and Infinity. encodeURIComponent(String(value)) then produces the path segment NaN or Infinity, and the request reaches the API with an invalid identifier. Fail in encodePathPart instead.

♻️ Proposed guard
 function encodePathPart(value: unknown, key: string): string {
 	if (typeof value === 'number') {

Describe the behavior instead of naming a review tool.

The comment ties the test rationale to a third-party review bot. That reference will not stay meaningful. State why an allowlist is used instead.

♻️ Proposed wording
-		// functions Greptile specifically called out that a denylist missed
+		// a denylist misses these; the allowlist rejects them by default
 		expect(isReadOnlySql('SELECT pg_sleep(30)')).toBe(false);

Narrow queryCall before indexing it.

Array.prototype.find returns T | undefined, and expect(queryCall).toBeDefined() does not narrow the type. The package typecheck reports TS18048 at queryCall[0]. Add a guard or non-null assertion.

The quoted-identifier call check rejected valid read-only queries such as
FROM f(x) AS "series" /* comment */ (value): after AS the quoted name is a
table alias and the parenthesized list names output columns, it is not a
function invocation. Mirror the bare-word branch's AS exemption for quoted
identifiers, and clear prevWord after any quoted identifier so the
exemption cannot leak to a following call — AS "series"(pg_sleep(1)) still
rejects. Regression tests cover the alias forms with and without comments
and the still-rejected call forms.

Maintainer review needed

Automated rounds are exhausted. Remaining findings:

  • P1 packages/prisma/pg-client.tsQuoted aliases rejected as calls
    When a valid read query uses a quoted alias column list with an intervening comment, such as AS "series" /* comment */ (value), skipSqlTrivia reaches the opening parenthesis and classifies the alias as a function invocation, causing sql.query to reject the side-effect-free SELECT before PostgreSQL executes it.
