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 | $0.00055 | $0.00291 |
| Opus 5.5 | $0.00022 | $0.00116 |
| Sonnet 5.5 | $0.00011 | $0.00058 |
| Haiku 4.5 | $0.00006 | $0.00029 |
Grade A, and why
outlook 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 15d 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
Outlook
The outlook-local-mcp server exposes six domain tools. Each tool takes a required operation verb.
calendar: events, availability, and schedules.mail: messages, folders, drafts, and attachments.account: the signed-in Microsoft accounts.system: server status and documentation.contacts: contacts and people. This domain is opt-in throughOUTLOOK_MCP_CONTACTS_ENABLED.teams: Teams messages and meeting transcripts. This domain is opt-in throughOUTLOOK_MCP_TEAMS_ENABLED.
Mail write verbs need OUTLOOK_MCP_MAIL_MANAGE_ENABLED.
Rules
- Call
operation="help"on a domain before you guess a verb or a parameter. - Read the resource id from each write confirmation. Use that id in the next call.
move_messagemakes a new message id. Use the new id after a move.teams.compose_replyreturns text only. It sends nothing.- If
OUTLOOK_MCP_READ_ONLYis set, the server refuses all write verbs. Tell the user.
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.

outlook is a skill published in the GitHub repository desek/outlook-local-mcp (44 stars, last pushed yesterday), licensed MIT. It adds 55 tokens to every session and 291 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-04.
