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 | $0.00043 | $0.02996 |
| Opus 5 | $0.00022 | $0.01498 |
| Sonnet 5 | $0.00009 | $0.00599 |
| Haiku 4.5 | $0.00004 | $0.00300 |
Grade A, and why
api-config 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 7d 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.
How it starts
The opening of the file, as written. The whole thing — 212 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Overview
Configuration has two layers: core config (managed by the framework, env-driven) and server config (your own Zod schema for domain-specific env vars). Never merge them.
Import: AppConfig, config, parseConfig, resetConfig, ConfigSchema from @cyanheads/mcp-ts-core/config.
Core config
Managed by @cyanheads/mcp-ts-core. Validated via Zod from environment variables. Uses a lazy proxy — parsing is deferred until the first property read.

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.
- 7d ago First seen · 212 lines · 43 tokens per session scan A 6cc01a758184
api-config is a skill published in the GitHub repository magnusquest/startgg-mcp (1 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 43 tokens to every session and 2,996 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
