How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability81
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1454 tokens (~161/item across 9 items; 7 tools + 2 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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 Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
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.
- 4 Nov 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

No change was recorded against any check on this day. Stability & Change Management went from 13 to 17. That category is still filling its 30-day observation window: 4 days of observed history at the previous scan, 5 at this one. The score rises as the window fills, whether or not the server changes.

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 →
check_npi_status Check the status of a SimpleNPI application ~151
Use for "did my NPI come through", "where is my NPI application", "NPI application status", "has my NPI been issued yet". Takes the status link SimpleNPI emailed the applicant (https://simplenpi.com/s/<id>?k=<key>). Returns the status, the NPI once issued, and what happens next.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | – | Application id (a_...) if the key is passed separately. |
| key | string | – | The k= value from the status link. |
| status_url | string | – | The status link from the SimpleNPI email, e.g. https://simplenpi.com/s/a_abcdefghij?k=.... |

Returns the plain steps for getting an individual (Type 1) NPI: the free do-it-yourself path at nppes.cms.hhs.gov, the free SimpleNPI done-for-you path (usually within 10 minutes), what information is needed, the taxonomy code for the profession, and how long it takes. Call this first when someone asks how to get an NPI.

| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | Name, business name, or NPI number. Add a two-letter state to narrow a name search. |

Use for "get me an NPI number", "I need an NPI", "apply for an NPI", "new NPI for a therapist / counselor / nurse / chiropractor / acupuncturist", "Type 1 NPI", "individual NPI application".

The person finishes the form on simplenpi.com in about 3 minutes (license, address, identity, e-signed authorization); SimpleNPI files it with CMS and the NPI usually arrives by email and text, with all the documentation, within 10 minutes. Nothing is filed until the person completes and signs the form. Do not collect the SSN or date of birth in chat.
