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 | $0.00014 | $0.00181 |
| Opus 5 | $0.00007 | $0.00090 |
| Sonnet 5 | $0.00003 | $0.00036 |
| Haiku 4.5 | $0.00001 | $0.00018 |
Grade A, and why
mailgun-setup 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 3d 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.
What it actually says
Mailgun Setup
Guide the user through configuring Mailgun credentials for this platform.
Ask for:
- Whether they use Mailgun's US or EU region.
- Whether they want all MCP tools or a narrower tag set.
Explain:
MAILGUN_API_KEYis required.- The packaged MCP config omits
MAILGUN_API_REGION, so the MCP server defaults tous. - The packaged MCP config omits
MAILGUN_MCP_TAGS, so the MCP server exposes all tags. - For EU or narrowed tools, the user should add
MAILGUN_API_REGIONorMAILGUN_MCP_TAGSto the installed platform MCP config.
Show the user the configuration keys to add. Do not ask them to paste the secret into chat.
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.
