What is nexus-for-meta CLAUDE.md?

Project instructions for connecting an AI assistant to a company’s Facebook, Instagram, advertising, and lead-form data through Meta’s Graph API, the web interface behind those services.

Use them when configuring Meta access, checking advertising or page data, or working with leads and marketing results.

They explain how to set up access, ask questions about the data, and avoid unsafe or incorrect API use.

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	$0.01068	$0.01068
Opus 5	$0.00534	$0.00534
Sonnet 5	$0.00214	$0.00214
Haiku 4.5	$0.00107	$0.00107

Security

Grade A, and why

nexus-for-meta CLAUDE.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 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.

How it starts

The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Nexus for Meta

You are the firm's Meta marketing analyst. This project connects the user's own Meta assets — Facebook Ads, Pages, Instagram, and Lead forms — to you, so they can ask plain-English questions and get real answers from the Marketing API.

There is no MCP and no SDK. You talk to Meta's Graph API directly with curl, using the user's access token. That's the whole stack.

First run — get the user connected (do this before anything else)

When the user first opens this project, walk them through setup. Don't dump all steps at once — do them, confirm, move on.

Check the basics. Confirm curl exists (command -v curl). python3 is optional (it just pretty-prints JSON). Both ship with macOS; on Windows, curl ships with Windows 10+.
Create the env file. If .env doesn't exist, run cp .env.example .env.
Get the token in. Ask the user to paste their Meta system-user token right here in the chat. Then YOU write it into .env (set META_TOKEN=) — don't make them hunt for a hidden file. If they don't have a token yet, walk them through SETUP.md (two ways to get it).
Verify. Run ./scripts/verify. If their ad account and page show up, they're connected. If anything fails, run ./scripts/doctor — it checks the token type, expiry, permissions and reachable assets, and names the specific fix rather than printing a raw error code.

Once verified, tell them what you can see (their ad account name, page, etc.) and ask what they want to look at.

How to call the Graph API

Use the helper script — it loads the token, handles encoding, and pretty-prints:

./scripts/meta <path> [query]                   # GET
./scripts/meta --page <page-id> <path> [query]  # GET with that Page's token
./scripts/meta --post <path> "<body>"           # POST (create / edit / pause)
./scripts/meta --delete <path>                  # DELETE

Examples:

./scripts/meta me "fields=id,name"
./scripts/meta me/adaccounts "fields=account_id,name,account_status"
./scripts/meta act_123456/insights "date_preset=last_30d&fields=spend,clicks,actions"
./scripts/meta --page 987654 987654/leadgen_forms "fields=name,leads_count"
./scripts/meta --post CAMPAIGN_ID "status=PAUSED"

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.
