A read-only MCP server for retrieving and analysing Google Ads account data through Google's query language, including campaign and conversion reports.

Use it to query campaigns, search terms, Performance Max and AI Max data, conversions, change history, and available Google Ads API v24 fields.

It gives an agent a controlled way to inspect advertising data while keeping account changes disabled by default and recording access in an audit log.

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	$0.00088	$0.01009
Opus 5	$0.00044	$0.00504
Sonnet 5	$0.00018	$0.00202
Haiku 4.5	$0.00009	$0.00101

Security

Grade A, and why

quantum-ads 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 10d 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.

Quantum ADS — Google marketing agency control plane (MCP, June 2026)

A FastMCP (stdio) server exposing the Google marketing stack as MCP tools, on a shared sovereign core. SP0 (this release) ships the core + a read-only Google Ads v24 connector. Write planes and other connectors (GA4, GTM, Merchant, Data Manager, DV360/CM360/SA360, …) land in later sub-projects.

Architecture in one screen

Transport: FastMCP over stdio (mcp.server / FastMCP 3.4), launched by python -m quantum_ads.
Core (shared): multi-tenant auth + secret store (tokens never reach the LLM), version manager (pinned v24, sunset guard, unknown-enum tolerance), GAQL build/validate/run engine with quota governors, safety spine (read-only by default, signed audit ledger), connector registry + meta-tool discovery.
Connector (SP0): Google Ads read — GAQL passthrough, opinionated reports, change history, field catalogs.

When to use

Pull metrics/reports from a Google Ads account (GAQL).
Inspect campaigns/search terms/PMax/AI Max/conversions, change history, or the v24 field surface.
Know the current (June 2026) API reality and what is sunset.

Critical first facts (June 2026)

Google Ads API v24.1 is current; library google-ads 31; monthly releases. v19 sunset 2026-02-11; v20 sunset 2026-06-10. This server targets v24.
Three API planes exist now: Google Ads API (v24) + Data Manager API (1st-party data — Ads-API conversion upload blocked 2026-06-15) + Merchant API (Content API sunsets 2026-08-18). SP0 covers Google Ads reads only; the others are later sub-projects.
Details: references/google-ads-2026-sota.md.

Setup (auth) — env vars, no secrets on disk

Set environment variables (or a gitignored .env); the client loads via load_from_env:

GOOGLE_ADS_USE_PROTO_PLUS=True
GOOGLE_ADS_API_VERSION=v24
GOOGLE_ADS_DEVELOPER_TOKEN=...
GOOGLE_ADS_CLIENT_ID=....apps.googleusercontent.com
GOOGLE_ADS_CLIENT_SECRET=...
GOOGLE_ADS_REFRESH_TOKEN=...
GOOGLE_ADS_LOGIN_CUSTOMER_ID=     # MCC only
QUANTUM_ADS_READ_ONLY=true        # SP0 is read-only

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
