Tool names and descriptions exactly as the server reported them on Nov 13, 2026. The maker wrote them, not us; we show them as plain text.
search_listingsFree, no wallet needed. Searches every live listing — private repos, agent skills, prompt packs, toolkits — by what it does: the name, the creator's description and "use this when" line, the computed tags (artifact class, what is inside such as `skills` or `scripts`, languages) a
how_to_buyFree, no wallet needed. Returns whether the listing is for sale, its latest version and new-buyer price, the listing page a person can buy on with a browser wallet, the step-by-step skill an agent with a wallet follows, the raw x402 endpoint, and this server's URL. If you cannot
get_listingWraps `GET /api/label/:owner/:slug`. The free, unauthenticated manifest for a listing's latest passing release: file tree, sizes, licence, dependencies, security-scan result and release log. Costs nothing and needs no wallet, so read it before you buy. Computed facts and the crea
check_versionWraps `GET /api/v/:owner/:slug`. The cheap call to make before every run: the latest version, when it was published, and the price. With `wallet_signature` it also answers what that wallet already owns and what the *next* fetch would cost it — `price_kind` is `new`, `update`, `fr
purchaseWraps `GET /api/r/:owner/:slug` — the same quote → screen → verify → settle → grant sequence, with the purchase recorded as `source: mcp`. Call it once with no payment: you get the x402 `PaymentRequired` body back. It arrives as `isError: true` per the x402 MCP transport, but it
fetch_releaseWraps `GET /api/r/:owner/:slug/v/:version`. A fresh five-minute download URL for a version this wallet already bought. Free, forever, including after the listing is retired. Never sells anything: if the wallet does not hold that version it is `not_entitled`, not a 402. `wallet_si

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (0.2.1) reached the registry 37 days ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).
