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 Security80
- 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 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 Usability57
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 3294 tokens (~823/item across 4 items; 4 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 Management75
- Stability check failed: schema churn in the 30 days we've observed: 1 tool removals, 0 breaking changes, 0 auth/transport breaks, 1 additions. See how to fix → Fail
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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- 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

report_coupon_result Report whether a coupon code worked ~1,092
Call this the turn the shopper says a code worked or failed. Records whether a coupon code or no-code deal tried at checkout worked (merchant and code for codes, including a code found outside McClipFace, with merchant as the store's domain; offer_id for no-code deals). Not a lookup. Stores no personal or cart data. Optional and off by default (Private mode, which lasts until the shopper changes it). Report only a confirmed result (the shopper says a code worked or was rejected, or a no-code deal did or didn't apply, or you saw it at checkout), never because a code was found, shown or copied. A result you saw counts only if you tried the code with checkout tools the shopper authorized, never an untested or unfinished one. One call per distinct code tested; a success counts even if another code saved more. Consent: report only in Community mode. At the first confirmed success in a conversation, once the purchase is done or declined (never mid-try, mid-purchase, next to the cart offer, or before or instead of a search), ask once: "Success! <code> worked: <saving> off. Want to turn on Community mode so other shoppers get this code too? Only the store, the code and the result are shared, never your cart or anything about you. (Yes / No)" Fill in the real code; leave out ": <saving> off" if the saving isn't known; start with "I tried N codes and" only if you tested them yourself, never for a code the shopper reports. If a try ends with no code working, ask once instead: "None of these worked. Want to turn on Community mode so other shoppers can skip codes that don't work? Only the store, the codes and the results are shared, never your cart or anything about you. (Yes / No)" Yes turns Community mode on for that conversation: report that result and later confirmed results, the shopper's and yours, until the shopper turns it off. No, or no answer, means report nothing and don't ask again in that conversation. It carries to later conversations only if the shopper agreed to…

| merchant | string | – | Store name as used with find_coupons, e.g. "Tommy John". Required with code; optional with offer_id. |
