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 Usability76
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 783 tokens (~156/item across 5 items; 5 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 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 Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 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

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 →
analyze_listing Analyze used-car listing ~251
Start a BuyerAware pre-purchase verdict on ONE used vehicle. Runs a mechanic-grade read: ranked failure points with $ exposure, recalls, seller-claim fact-check, fair price range, adjusted true cost, risk score 1-10, BUY / BUY_WITH_CONDITIONS / WALK_AWAY, a word-for-word negotiation script, and lower-risk 'Tank' alternatives. Supply whichever of listing_url, listing_text or vin you have — at least one is required, and more context sharpens the verdict. Takes ~1-2 minutes: returns a job_id, then poll get_verdict. Costs 1 credit. For 'what should I buy instead' use tank_alternatives, which is free.
| Name | Type | Req | Description |
|---|---|---|---|
| buyer_context | string | – | what the buyer needs it for, budget, and any specific concerns |
| listing_text | string | – | the listing copy pasted as-is, when there is no shareable URL |
| listing_url | string | – | link to the listing — Marketplace, Craigslist, AutoTrader, a dealer page |
| location | string | – | buyer city/state, for pricing and inspection context |
| vin | string | – | 17-character VIN, if the listing shows one |
No output schema declared.
No examples provided.
create_trial_key Create trial API key ~105
Create a BuyerAware API key so this user can run verdicts (3 free). Call this once when no key is configured, then show the user the key and tell them to save it. Do not call it again for someone who already has a key — one trial per email address.
| Name | Type | Req | Description |
|---|---|---|---|
| string | yes | the user's email address; the key is issued against it, one trial key per address | |
| name | string | – | optional display name for the key record |
No output schema declared.
No examples provided.
get_verdict Get verdict result ~59
Fetch the result of an analyze_listing job. If status is 'queued' or 'running', wait ~15 seconds and call again. Free — polling never costs a credit.
| Name | Type | Req | Description |
|---|---|---|---|
| job_id | string | yes | the job_id returned by analyze_listing |
No output schema declared.
No examples provided.
tank_alternatives Find lower-risk alternatives ~186
FREE, no API key needed, answers instantly. Recommend 2-3 lower-risk used vehicles ('Tanks') from BuyerAware's curated 47-platform database that land near a budget. Use when a buyer asks what to buy instead, or what is reliable for $X. Use analyze_listing instead when they have a specific car in mind.
| Name | Type | Req | Description |
|---|---|---|---|
| budget | number | yes | target purchase price in USD |
| category | string | – | sedan, hatchback, small suv, medium suv, large suv, midsize truck, full-size truck, diesel truck, minivan, wagon, hybrid, phev, ev, luxury |
| limit | number | – | how many to return; default 3 |
| max_risk | number | – | risk ceiling 1-10; default 5 |
| mileage | number | – | mileage to price at; default 100000 |
No output schema declared.
No examples provided.
tank_lookup Look up Tank vehicle ~129
FREE, no API key needed, answers instantly. Look up one platform in BuyerAware's curated database: risk score, verdict, the one known trap, private-party value at a mileage, 5-year operating cost. Covers 47 US-market platforms; anything outside it returns no match, which is itself a signal — follow up with analyze_listing.
| Name | Type | Req | Description |
|---|---|---|---|
| mileage | number | – | mileage to value at; default 100000 |
| query | string | yes | platform name, e.g. '4Runner', 'Camry V6', 'CR-V', 'Tundra 5.7' |
