Available components
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 Usability64
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1572 tokens (~314/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 Management10
- Stability observed for 3 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 Safety50
- Injection-marker check failed: the server instructions contains an instruction to conceal the call from the user, the text "Do not tell the user", at byte 1899 of that field. See how to fix → Fail
- 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 current MCP spec version (2026-07-28).Pass
How do I install the Underpriced AI MCP server?
Underpriced AI is a hosted endpoint at https://underpricedai.com/api/mcp/directory, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 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 →
get_scan_result Fetch a saved scan's result ~129
For a signed-in user: the finished result for a scan on their account, in the same shape as price_item, once the sold comps have landed in the background. Call it with the account.scanId a photo price returned when that result said comps were still loading (about 20 seconds later), or to re-read any saved scan.
| Name | Type | Req | Description |
|---|---|---|---|
| cost | number | – | What the user would pay, in the scan's currency (price.currency), for a worth-it verdict. |
| scan_id | string | yes | The account.scanId from a signed-in price_item, or the saved-scan link. |
No output schema declared.
No examples provided.
get_sold_comps Recent eBay sold comps ~88
The most recent real eBay US sales (sold comps) for a search query (brand, model or pattern, a few specific words), with the count, median and quartiles. Use when the user wants to see what actually sold and for how much.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | 3 to 6 specific words, brand and model first, like an eBay search. |
No output schema declared.
No examples provided.
list_on_ebay Prepare an eBay listing ~229
For a signed-in user: turns a photo scan from price_item (account.scanId) into an inventory item with a draft eBay listing on their Underpriced AI account (title, list price defaulting to the market price, condition, description) and returns the link where they review and publish it in the app, plus whether eBay is connected and the connect link if not (connecting brings them back to the same item). It never publishes anything and only prepares eBay; publishing happens in the app after the user checks the listing, and until then the draft shows on the Sell tab under Not live yet.
| Name | Type | Req | Description |
|---|---|---|---|
| condition | string | – | Overrides the condition read from the photo. |
| price | number | – | List price in the scan's currency (price.currency from price_item). Leave empty for the scan's market list price. |
| scan_id | string | yes | The account.scanId that price_item returned for a photo scan on this account (the saved-scan link works too). |
| title | string | – | Overrides the generated listing title (80 characters, eBay's limit). |
No output schema declared.
No examples provided.
price_item Price an item ~258
What a secondhand item sells for on eBay: a calibrated estimate with a range, the recent real eBay sales behind it (sold comps, linked where the source gives a link), three list prices (fast, market, patient) with the 14-day sell chance, what the seller keeps after eBay fees, and a worth-it verdict when you pass what the user would pay. Description prices are eBay US in USD. A photo price (image_url, a public https link) needs the user signed in through the connector: it runs a real scan on their account, priced in their own eBay marketplace and currency (price.currency). Without sign-in, describe the item; a description works but reads less than a photo.
| Name | Type | Req | Description |
|---|---|---|---|
| condition | string | – | Condition as the user states it. |
| cost | number | – | What the user paid or would pay for it, for a worth-it verdict: in USD, or in the seller's own currency for a photo scan on a signed-in account. |
| description | string | – | What the item is: brand, model or pattern, size, any marks, completeness. |
| image_url | string | – | Public https URL of a photo of the item. Preferred over description alone. |
No output schema declared.
No examples provided.
worth_it Worth buying at this cost? ~88
What the seller keeps after eBay fees and a verdict (worth it / thin / pass) for an expected sale price and what the user would pay. Pure arithmetic in USD; use price_item first when the sale price is unknown.
| Name | Type | Req | Description |
|---|---|---|---|
| cost | number | yes | What the user would pay for the item in USD. |
| expected_sale_price | number | yes | Expected eBay sale price in USD. |
No output schema declared.
No examples provided.
