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 Security83
- 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
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability75
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 341 tokens (~170/item across 2 items; 2 tools + 0 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 Management23
- Stability observed for 7 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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 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 →
create_jfpi_link Create a JFPI link ~250
Creates a Just Fucking Prompt It (JFPI) link for a question someone could have asked an AI themselves. JFPI is a joke site in the spirit of "Let Me Google That For You": whoever opens the link watches the question being typed into an AI, then gets a cheeky answer in the chosen tone. Use it only when the user asks for a JFPI or "just prompt it" link for someone else, or explicitly wants to tease another person about a question that was easy to ask an AI. Do not use it on your own initiative, and never use it to mock the user you are talking to. Input: the other person's question, as they asked it (max 500 characters). Optional tone: mild, rude, brutal (default mild). The site checks every question; offensive or abusive ones are refused. Returns the link and a short line in the chosen tone that you can say together with it. Give the user the link exactly as returned.
| Name | Type | Req | Description |
|---|---|---|---|
| question | string | yes | The other person's question, as they asked it. Max 500 characters. |

list_tones List JFPI tones ~57
Lists the tones a JFPI link can have (mild, rude, brutal), each with a one-line description and an example of how the answer opens. Use it when the user wants to choose how rude the link should be.
Input schema present but exposes no named parameters.
