Summary

  • prompt for the Supabase project ref before generic MCP OAuth
  • add --supabase-project-ref for automation and non-interactive deploys
  • normalize and validate the ref, then send it through the connect-session request
  • fail closed when Supabase OAuth would otherwise start without project scoping

Deployment note

Pair with AgentWorkforce/cloud#3226. Deploying the Cloud change first makes existing account-wide connections report pending; the next agentworkforce deploy then reconnects them with the project-scoped, read-only URL.

Validation

  • deploy package: 271/271 tests passed
  • CLI typecheck passed
  • focused deploy-command tests: 20/20 passed
  • full CLI suite: 372/373 passed; the unrelated AGENT_WORKFORCE_CONFIG_DIR whitespace test failed in the local environment
  • diff and secret-pattern review

Veto MCP was requested by repo instructions but is not available in this environment, so equivalent local type, test, diff, and secret scans were run.

📝 Walkthrough

Walkthrough

The deploy CLI adds --supabase-project-ref. The deploy flow normalizes and validates the value, prompts when needed, and includes it in Supabase MCP connect-session requests.

Changes

Supabase project reference support

Layer / File(s) Summary
CLI parsing and validation
packages/cli/src/deploy-command.ts, packages/cli/src/deploy-command.test.ts, packages/cli/CHANGELOG.md
The CLI supports space-separated and inline flag forms. It lowercases valid 20-character references and rejects invalid values.
Deploy option propagation
packages/deploy/src/types.ts, packages/deploy/src/deploy.ts, packages/deploy/src/deploy.test.ts, packages/deploy/CHANGELOG.md
DeployOptions and deployment orchestration forward supabaseMcpProjectRef into integration connection setup.
Supabase connection resolution
packages/deploy/src/connect.ts, packages/deploy/src/connect.test.ts
Supabase MCP providers require a valid project reference. The flow uses configured values, prompts interactively, rejects missing values under --no-prompt, and sends the normalized reference in the connect-session request.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 2ad2f

A deploy can treat an existing Supabase connection as ready before checking whether it belongs to the requested project, and completion does not independently verify that project binding. This could leave deployments using the wrong project connection, so merge should wait for project-aware checks or explicit owner acceptance.

Poem

A rabbit checks the project key,
Then hops through lowercase carefully.
The MCP path receives the ref,
Prompts fill gaps with due respect.
Tests watch each connection gleam.

🔴 Selected Supabase project gets ignored

When Supabase is already connected elsewhere, supabaseMcpProjectRef never participates in the status check. Deploy accepts the wrong project and skips reconnection.

Prompt for agents
Make Supabase connection checks project-aware. The project reference currently reaches IntegrationConnectResolver.connect only after connectIntegrations has accepted or rejected the existing generic provider status. Extend the status-check contract and relayfile status request so supabase-mcp and supabase-mcp-relay are considered connected only when the ready connection matches the normalized requested project ref. Ensure a ready connection for a different project enters the reconnect flow, while non-Supabase providers remain unchanged. Add tests for a ready project-A connection with project B requested, both interactive and non-interactive.

Fixed in 8c420c1 with the paired Cloud status contract in AgentWorkforce/cloud#3226. The normalized requested project ref is now sent during status preflight and OAuth polling; a ready connection for a different project returns unmatched and enters reconnect. Tests cover project-aware status, interactive replacement, and older-Cloud fail-closed behavior.

P2 Badge Allow the project ref through the no-prompt gate

When a fresh supabase-mcp connection is deployed with the advertised --no-prompt --supabase-project-ref <ref> combination, execution never reaches this new project-aware connect block: the input.noPrompt && !forceReconnect branch at lines 761–770 returns a failed outcome first. Consequently, non-interactive deployments cannot establish the connection unless callers also discover and supply the unrelated --reconnect supabase-mcp flag; a supplied valid project ref should enable the intended non-interactive path without requiring that workaround.

Fixed in 8c420c1. A valid --supabase-project-ref now authorizes the Supabase connect path under --no-prompt without requiring --reconnect, while non-Supabase providers retain the existing no-prompt gate. Added a regression test for this exact combination.

IntegrationConnectResolver.isConnected logic so stored connection scope is
