What is firebase-mcp-server CLAUDE.md?

Repository instructions for a Firebase MCP server that provides access to Firestore, Storage, Authentication, and Cloud Logging with schema validation. MCP is a way for AI tools to call external services through defined functions.

Use them when developing, testing, or releasing the Firebase server, particularly when changing shared path-matching or validation code. Live integration checks require real Firebase credentials.

They explain the project's conventions, build and test commands, and release process so agents can make changes without breaking its checks or publishing workflow.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00598	$0.00598
Opus 5	$0.00299	$0.00299
Sonnet 5	$0.00120	$0.00120
Haiku 4.5	$0.00060	$0.00060

Security

Grade A, and why

firebase-mcp-server CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

CLAUDE.md — working conventions for this repo

What this is

A general-purpose MCP server for Firebase — Firestore, Storage, Auth, and Cloud Logging — with schema-driven validation and context-efficient tools. Published as @dasasian/firebase-mcp-server (npm) and io.github.dasasian/firebase-mcp-server (the MCP registry).

Build / test

npm run build (tsc) · npm run typecheck (tsc --noEmit) · npm test (vitest).

Tests cover the pure logic — path matching (src/shared/path-matcher.ts) and schema validation (src/shared/validation.ts) — the parts that don't need live Firebase. The test-*.ts scripts at the repo root are manual integration checks that need real credentials and deliberately do not run in CI. Keep the unit suite green, and add to it when you touch src/shared/.

Releasing

MCP server → npm and the MCP registry. Full process + every gotcha: ../PUBLISHING.md. The short version:

Update CHANGELOG.md ([Unreleased] → [X.Y.Z] — <date>). No CHANGELOG.md yet? Create one (Keep a Changelog format) and backfill the already-published versions from git log + the GitHub releases.
Bump version in both package.json and server.json (including server.json's packages[].version) — a drift between them fails the registry publish.
Commit chore: release X.Y.Z and push.
npm publish — needs your OTP. Traps: a 404 on PUT = lapsed token (npm login); npm view can 404 for ~2 min after a successful publish (confirm with npm access list packages, don't re-publish).
git tag vX.Y.Z && git push origin vX.Y.Z — fires publish-mcp-registry.yml, which publishes server.json to the registry via OIDC (npm X.Y.Z must already be live). Never run mcp-publisher from your laptop — it 403s on the org namespace.
gh release create vX.Y.Z with the CHANGELOG notes; verify the registry shows X.Y.Z as isLatest (the search returns all versions — read the isLatest one).
Update the dasasian.com/firebase-mcp-server page in dasasian-web. Only npm publish and the release need your credentials; an agent drives the rest.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
