## MCP tools (5)

### `snds_authenticate` (~62 tokens)

Sign in to Outlook SNDS. Opens your browser for a Microsoft-account login (OAuth 2.0 authorization-code + PKCE, loopback redirect) and caches the tokens for later calls. Run this once before fetching reports; tokens are refreshed automatically afterward.

### `snds_auth_status` (~33 tokens)

Check whether you are currently signed in to SNDS, which account is cached, and when the access token expires.

### `snds_sign_out` (~36 tokens)

Delete the cached SNDS tokens from disk (sign out). You will need to run snds_authenticate again to fetch data.

### `get_data_report` (~187 tokens)

Get the SNDS IP Data report (per-IP traffic and reputation metrics: RCPT/DATA commands, message recipients, spam filter result, complaint rate, trap hits, sample HELO/MAIL, comments). With no arguments it returns the most recent available report. Optionally pass a date (yyyy-MM-dd) for a specific day, and optionally an IPv4 address to filter to a single IP (a date is required to filter by IP). Calls GET /api/report/data/{date?}/{ip?}.

Input parameters:

- `date` (string): Optional report date in yyyy-MM-dd format, e.g. 2026-12-31. Omit for the most recent available report.
- `ip` (string): Optional IPv4 address to filter the report to a single IP, e.g. 1.2.3.4. Requires "date" to also be set.

### `get_ip_status` (~63 tokens)

Get the SNDS IP Status report for the IPs you own — the set of IPs with an abnormal status at Outlook.com (e.g. Blocked, Bot, Junked) as of the last 24 hours. Calls GET /api/report/status/ip.
