How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security13
- No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.Unverified
- Known CVEs could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified
- No install/post-install scripts declared.Pass
- Dependency health could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 103 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability80
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 381 tokens (~76/item across 5 items; 5 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "snds_sign_out" implies "delete" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

No change was recorded against any check on this day. Stability & Change Management went from 83 to 87. That category is still filling its 30-day observation window: 25 days of observed history at the previous scan, 26 at this one. The score rises as the window fills, whether or not the server changes.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_data_report ~187
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?}.
| Name | Type | Req | Description |
|---|---|---|---|
| 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. |
No output schema declared.
No examples provided.
get_ip_status ~63
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
snds_auth_status ~33
Check whether you are currently signed in to SNDS, which account is cached, and when the access token expires.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
snds_authenticate ~62
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
snds_sign_out ~36
Delete the cached SNDS tokens from disk (sign out). You will need to run snds_authenticate again to fetch data.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
How do I install the Outlook SNDS MCP server?
Outlook SNDS ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. The MCP registry declares no SHA-256 for this bundle, so there is no published digest to check the download against.
