Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00036 | $0.00272 |
| Opus 5 | $0.00018 | $0.00136 |
| Sonnet 5 | $0.00007 | $0.00054 |
| Haiku 4.5 | $0.00004 | $0.00027 |
Grade A, and why
kg-overview scanned grade A with 0 findings 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Horacio + KG Educación
El MCP de Horacio usa un KG educativo privado, independiente y no afiliado a MINEDUC. La key personal autentica la cuenta; sus features y grants se evalúan en cada llamada.

Flujo: recupera evidencia, usa materiales cuando aporten y estén habilitados, y luego sintetiza o ejecuta el workflow docente pedido. Conserva citas y procedencia. No inventes OA, ids o contenido ausente. Si una tool está deshabilitada, no regeneres la key: revisa los permisos de la cuenta.
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.
