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 | $0.02587 | $0.02587 |
| Opus 5.5 | $0.01035 | $0.01035 |
| Sonnet 5.5 | $0.00517 | $0.00517 |
| Haiku 4.5 | $0.00259 | $0.00259 |
Grade B, and why
meta-ads-mcp CLAUDE.md scanned grade B 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 1mo 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

How it starts
The opening of the file, as written. The whole thing — 149 lines — stays where its author put it; the contents beside it link to each section on GitHub.
meta-ads-mcp — agent guide
Project memory for Claude Code, Codex and any other AI assistant. CLAUDE.md and AGENTS.md are the same document, kept identical; edit both. This file is committed and shared with everyone working on the repo.
What this project is
A Model Context Protocol server that brokers Meta Ads API access for advertising agencies. Multi-tenant, OAuth-gated, with encrypted-at-rest token storage in Firestore. Deployed to Google Cloud Run.
- Stack: Node 22.13+, TypeScript (ESM), Express 5, vitest, Pino, zod 4, Firestore. MCP SDK 1.30 (
registerToolAPI +ToolAnnotations). ffmpeg in the image for the video tools. - Entry: src/index.ts → src/transport/http.ts.
- Deploy: push to
maintriggers .github/workflows/deploy.yml. PRs trigger .github/workflows/ci.yml. - License: MIT. Repository is public on GitHub.
Conventions specific to this repo (v3.0.0+)
- Tool naming:
ads_*prefix (nometa_).ad_setwith underscore (notadset). Aligned with Meta's official MCP server (mcp.facebook.com/ads). See docs/migration-v3.md for the full rationale. - Tool registration: always
server.registerTool(name, { description, inputSchema, annotations }, handler). The legacyserver.tool(...)API is removed. - Annotations: every tool spreads one of the constants from src/tools/_register.ts (
READ/CREATE/UPDATE/DELETE/TOGGLE/UPLOAD/TOKEN) into itsannotationsfield. Write tools prependWRITE_WARNINGto the description. - Adding tools: see docs/adding-a-tool.md for the full template + checklist.

What this file has done since we first saw it
