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 | $0.00100 | $0.01138 |
| Opus 5 | $0.00050 | $0.00569 |
| Sonnet 5 | $0.00020 | $0.00228 |
| Haiku 4.5 | $0.00010 | $0.00114 |
Grade A, and why
check-email 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 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.
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 — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Use the mailbridge MCP tools to fetch and present emails.
Reading Recent Emails
Call read_emails with folder (default: INBOX) and limit (default: 10).
Each email now includes priority (1–5) and category fields — surface these when useful:
- Priority 5 or 4 → flag with 🔴 in the list
- Category "Finance", "Travel", "Calendar" → show the category badge
Present results as a numbered list:
1. 🔴 [From] Subject — Date (priority 5)
2. [From] Subject — Date
If the user wants the body of a specific email, call get_email_body with its uid.
Display the body cleanly — strip excessive whitespace, preserve paragraph breaks.
Searching Emails
If the user mentions a sender name, keyword, or subject, call search_emails with a query.
After getting UIDs back, offer to fetch the full body of any result.
Thread View
When the user says "show the full thread", "see the whole conversation", or "what's the context":
- Call
get_threadwith the emailuidandfolder - Present messages in chronological order:
**Thread — [Subject]** ([N] messages) 📩 [From] · [Date] [Preview...] 📩 [From] · [Date] [Preview...] - Offer to summarise: "Want a quick summary of this thread?" — if yes, condense to 3 bullet points.
Contact History
When the user asks "what's the history with [person]", "show emails from/to [contact]", or "have I emailed X before":
- Call
get_contact_historywith the contact'saddress - Present as a timeline: Sent / Received labels, sorted oldest to newest
- Note patterns: "You've exchanged 8 emails — 3 sent, 5 received"
Calendar Event Extraction
When the user asks "any events in this?", "what's the date of this meeting?", or "add this to my calendar":
- Call
extract_calendar_eventswith theuidandfolder - If events found, present them clearly:
📅 **[Event Title]** Start: [date/time] Location: [location] - Offer to set a reminder via
set_reminder
Export Email
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.
- 9d ago First seen · 125 lines · 100 tokens per session scan A 458aee9a871d
check-email is a skill published in the GitHub repository Creativestefan/mailbridge-mcp (2 stars, last pushed 2mo ago), licensed MIT. It adds 100 tokens to every session and 1,138 once invoked, about $0.0005 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.
