admob-mcp AGENTS.md

Instructions for an MCP server that connects an application to Google AdMob, Google's platform for managing mobile-app advertising.

In plain words
What is it for?
Set up the local or web server, authenticate with AdMob, run its available reporting and optimization tools, and deploy it.
Why use it?
They provide the commands and project structure needed to build, test, authorize, run, and deploy the server. This avoids having to work out the OAuth login and API connection from scratch.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.

Security

Grade A, and why

admob-mcp AGENTS.md scanned grade A with 1 finding 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 2d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- `CONNECTOR_TOKEN` gates `/api/setup`, `/oauth/authorize`, and is also accepted as a direct bearer for `/api/mcp` (useful for curl-testing). Comparison is timing-safe.

AdMob MCP Server

Local MCP server that connects Claude to the Google AdMob API via OAuth 2.0.

Build & Run

npm install
npm run build           # tsc → dist/ (mirrors src/, api/, tests/)
npm test                # vitest unit tests
npm run start           # run stdio server on stdio
npm run dev:vercel      # vercel dev (HTTP mode, requires .env.local)
npm run deploy          # vercel deploy --prod
./setup.sh              # interactive: pick local / vercel / both
./setup.sh --mode=local # non-interactive
./setup.sh --reauth     # re-authorize (mode-aware)

Project Layout

  • src/index.ts — stdio MCP entry point. Calls registerTools(server, getClient) with FileTokenStore.
  • src/tools.ts — all tool definitions (6 core + 10 reporting + 20 optimization). Exports registerTools(server, getClient).
  • src/auth.ts — OAuth helpers. getAuthenticatedClient(creds, store) is the headless refresh path used by both modes; authorizeViaLocalServer(creds, store) is the interactive CLI flow.
  • src/authorize.ts — Standalone CLI script for OAuth authorization (run by setup.sh for local mode).
  • src/admob-client.ts — Thin REST client over https://admob.googleapis.com/v1.
  • src/helpers.ts — Date math, report row parsing, table formatting, period-over-period change utils.
  • src/token-store.ts — TokenStore interface, FileTokenStore (local), KvTokenStore (Vercel KV).
  • src/oauth-store.ts — KV-backed storage for the connector OAuth flow: short-lived auth codes (oauth:authcode:<code>, 10-min TTL) and long-lived access tokens (oauth:token:<token>).
  • src/http-auth.ts — checkBearer (sync, against CONNECTOR_TOKEN) used by /oauth/authorize and /api/setup; checkBearerAsync (also accepts KV-issued access tokens) used by /api/mcp.
  • api/mcp.ts — Vercel function: Streamable HTTP MCP endpoint. Bearer-gated. Returns WWW-Authenticate: Bearer realm="admob-mcp", resource_metadata="…" on 401 per the MCP authorization spec.
  • api/setup.ts — Vercel function: GET form + POST handler that initiates the Google ↔ server OAuth flow. Server's grant on AdMob.
  • api/oauth/callback.ts — Vercel function: Google's redirect URI; stores tokens in KV.
  • api/oauth/authorize.ts, api/oauth/token.ts, api/oauth/register.ts — Vercel functions implementing the Claude.ai ↔ server OAuth 2.1 flow with PKCE (S256) and Dynamic Client Registration. Required because Claude.ai's connector UI doesn't accept static bearer tokens — it negotiates its own access token.
  • api/well-known/oauth-authorization-server.ts, api/well-known/oauth-protected-resource.ts — RFC 8414 / RFC 9728 metadata endpoints; reached at root paths (/.well-known/...) via vercel.json rewrites so Claude.ai's discovery works.
  • vercel.json — Vercel function runtime + per-function timeouts + rewrites mapping /.well-known/* and /oauth/* to the api/ directory.
  • .env.example — Template for Vercel mode env vars.
  • secrets/ — Git-ignored. Local-mode client_secret.json and token.json live here.
  • setup.sh — Interactive setup: pick [L]ocal / [V]ercel / [B]oth. Supports --mode= and --reauth.
  • docs/VERCEL.md — Forker-facing deploy guide for the Connector path.
  • tests/ — vitest unit tests (token-store.test.ts, http-auth.test.ts).
  • CLAUDE.md — Symlink to this file.

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.
