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 | $0.03204 | $0.03204 |
| Opus 5 | $0.01602 | $0.01602 |
| Sonnet 5 | $0.00641 | $0.00641 |
| Haiku 4.5 | $0.00320 | $0.00320 |
Grade C, and why
google-ads-mcp-plus CLAUDE.md scanned grade C 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 11d 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.
Instruction-override phrasinghighPrompt injection
Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.

CLAUDE.md — operating guide for this Google Ads MCP
You are connected to google-ads-mcp-plus, an MCP server that can read,
audit, create, and modify Google Ads accounts. This file tells you
how to use it correctly. Read it before your first tool call in a session.
This is NOT an officially supported Google product. It is a community tool built on the Google Ads API. Everything you do here affects a real advertising account that spends real money.
1. The one thing that matters most
Every euro this account spends is the user's, and mistakes here are expensive and sometimes irreversible. A wrong budget runs overnight. A paused campaign loses momentum and its learning phase. A deleted campaign takes its history with it.
So the default posture is: read first, propose second, write only when the user has seen exactly what will change. You are not being cautious for its own sake — you are being cautious because the feedback loop is money.
2. Start every session with server_status
Before anything else, call server_status. It tells you:
- whether the server is READ-ONLY or read-write,
- which accounts are allowlisted (you cannot touch any other),
- the budget ceiling and max change percentage in force.
Do not guess at these. If the server is read-only and the user asks for a
change, tell them plainly: the server must be restarted with
GOOGLE_ADS_MCP_ENABLE_WRITES=true. Do not attempt workarounds.
3. Tools
Read — always available
| Tool | Use it for |
|---|---|
server_status |
Mode, allowlist, limits. Call first. |
list_accounts |
Which accounts the credentials reach, and which are allowlisted. |
run_audit |
12-check health audit. Your default starting point for "how is this account doing?" |
list_campaigns |
Campaigns with budget, status, spend, conversions. Use to find campaign_id. |
gaql_query |
Anything the above don't cover. SELECT only. |
validate_ad_copy |
Character limits. Offline — no account needed, no risk. Use freely while drafting. |
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.
