Presets: add Firebase MCP and Google Firebase/Firestore REST catalogs

[kjhq]

What

Adds Firebase to the well-known integration catalogs, three entries across two
plugins:

MCP stdio preset (packages/plugins/mcp/src/sdk/presets.ts) — the official
Firebase CLI MCP server (GA since Oct 2025):

 {
id: "chrome-devtools",
name: "Chrome DevTools",
summary: "Debug a live Chrome browser session via local stdio.",
icon: "https://integrations.sh/logo/chrome.com",
featured: true,
transport: "stdio",
command: "npx",
args: ["-y", "chrome-devtools-mcp@latest"],
},
+ {+ id: "firebase",+ name: "Firebase",+ summary: "Manage projects, Auth, Firestore, rules, and deploys via the Firebase CLI.",+ icon: "https://integrations.sh/logo/firebase.google.com",+ featured: true,+ transport: "stdio",+ command: "npx",+ args: ["-y", "firebase-tools@latest", "mcp"],+ },

Google catalog REST presets (packages/plugins/openapi/src/providers/google/)
— Firebase Management + Cloud Firestore via the Google Discovery conversion:

• presets.ts: google-firebase (firebase.googleapis.com/v1beta1, 9 project
  methods: projects, apps, hosting, extensions) and google-firestore
  (firestore.googleapis.com/v1: documents, collections, queries, indexes),
  both oauthAudience: "advanced-user", plus a firebase.projects.list
  health check (Firestore intentionally gets none — no stable cheap read,
  per the existing catalog convention).
• service-policy.ts: consent scopes (firebase, datastore) and policy
  entries for firebase/v1beta1 + firestore/v1.
• presets.test.ts: frozen-slug list + snapshot updated for the two new rows.

Why

Firebase's MCP server covers project management, Auth users, Firestore, rules,
Cloud Messaging, and deploys — but is stdio/local only, so it suits local and
desktop executor hosts. The Google REST presets give remote hosts the same
reach (OAuth): Firebase Management for project/app configuration, Firestore
for document data.

Verified against live sources: both Discovery documents resolve
(firebase/v1beta1 — scopes firebase, firebase.readonly,
cloud-platform; firestore/v1 — scopes datastore, cloud-platform), and
the official docs confirm the GA invocation npx -y firebase-tools@latest mcp.

Verification

1. bun install.
2. bun run format then bun run format:check.
3. bun run lint and bun run typecheck.
4. bun run test (turbo, e2e excluded).

All gates pass locally: format/lint/typecheck clean,
@executor-js/plugin-openapi 283 tests pass (incl. google catalog tests),
@executor-js/plugin-mcp 138 tests pass (29 skipped are the live-server
tests, skipped by default).

Changeset

.changeset/firebase-presets.md — @executor-js/plugin-mcp + @executor-js/plugin-openapi patch.
