Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

mcp-outlook-lite AGENTS.md 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 8d 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

Agent Guidelines for mcp-outlook

If you are an AI agent with access to this MCP server's tools (prefixed outlook_), follow these guidelines.

Before operating on items

Always list or search first — you need the messageId, eventId, or attachmentId before you can read, modify, or delete anything.

High-stakes actions

These actions have real-world consequences. Confirm with the user before executing:

  • outlook_send_email — sends an actual email
  • outlook_reply_to_email / outlook_reply_all / outlook_forward_email — sends a reply
  • outlook_delete_email / outlook_delete_event / outlook_delete_rule — permanent deletion
  • outlook_create_rule — affects future mail routing

Attachment handling

outlook_download_attachment with includeContent: true automatically parses:

  • PDF → extracted text
  • Word (.docx) → extracted text
  • PowerPoint (.pptx) → slide text
  • Excel (.xlsx) → structured sheet data

Set decodeContent: false to get raw base64 instead.

Search tips

  • outlook_search_emails supports free-text search across all folders
  • Use from, subject, startDate, endDate for targeted queries
  • Set includeBody: true to get full email content (max 5 results)
  • outlook_list_emails with folder parameter for browsing specific folders

Error handling

If a tool returns isError: true, the error message describes what went wrong. Common causes:

  • Authentication expired (will auto-refresh on next call)
  • Missing required parameters
  • Resource not found (wrong ID)
Changes

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.
