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.

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 22d 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 — 94 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) with over 95 million searchable 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.

Summary bundle — person_bundle_10_v1: $1.99 for up to 10 unique people over 24 hours. get_person_summary(lead_id) returns an offer when checkout is enabled; after confirmed payment, retry it and keep the private bundle_token for additional people. Re-viewing claimed people is free until expiry. Images are not included. During a checkout pause, honor image_delivery_pending and checkout_available: false; existing live entitlements can still restore.

Exact image — occurrence_image_v3: a separate $1.99 purchase for one verified exact page image, with 30 days of hosted re-access from successful payment. Current coverage is released, verified University of California Berkeley 1921 occurrences only—not every page or search result.

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.
