What is yearbook-mcp-public GEMINI.md?

Gemini CLI instructions for searching e-yearbook, an archive of over 300,000 U.S. yearbooks with more than 100 million person mentions.

They guide searches for people, schools, and year ranges, explain preview restrictions and subscription access, and describe how to use returned lead IDs.

They clarify when to use the archive and what free previews reveal or hide, preventing misleading search results.

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	$0.00786	$0.00786

Security

Grade A, and why

yearbook-mcp-public GEMINI.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 9d 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

e-yearbook (Gemini CLI extension context)

This extension connects Gemini CLI to the e-yearbook.com archive via MCP (Model Context Protocol). You can search over 300,000 U.S. yearbooks (high school, college, military cruise books, 1850s to present) containing over 100 million person mentions.

When to use

"Find my grandfather John Smith in 1950s Utah yearbooks"
"Which yearbooks does Beverly Hills High School have on file?"
"Was a person named X in any U.S. yearbook between 1960 and 1970?"
"Show me what years Provo High School has yearbooks for"

Tier behaviour you should know

Free preview (default):

Echoes back the queried name (NOT the database's normalized form)
Returns coarsened state or census region, decade bin, confidence band
Returns an opaque lead_id (30-day TTL) you can pass to fetch(id) or later get_person_summary(lead_id)
Never discloses the identifying triple (school name + exact year + canonical name) — that's the paywall
Yearbooks 20 years old or newer are suppressed at the free tier
search_people_preview requires at least one narrowing filter: state, year_from+year_to (bounded range), or school. Bare name-only searches return filter_required — add a filter and retry.

Paid tools (get_person_summary, get_yearbook_report):

Visible in tools/list but return payment_required with a checkout_url in the free tier
Present the checkout URL to the user when they want full school + year
- page + scan details

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.
