Available tools 9

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

z2h

z2h_compare_marketplace_listings

Compare a shortlist of public software from marketplace search. Returns current public descriptions, USD license prices, types and tech stacks. Unavailable software is omitted without disclosing its status. This tool cannot purchase software or access private source.

z2h_confirm_source_upload

After the signed PUT succeeds, verify and attach the archive to the owned draft. Confirm that the Builder accepted "I own or have the rights to sell the codebase I am about to upload."; pass ownershipAccepted=true and ownershipVersion=2026-09-27. The server records the accepted wording with the source change. Final review and publishing stay in the web wizard.

z2h_create_draft_listing

Create an invisible draft and return editUrl and publishUrl. Price and source inclusion are Builder decisions. Set sourceCodeIncluded only after confirmation; omitted values default to false. Requires listings:write. Returns the draft identity, web edit/review links and warnings (quality advice about the saved draft, never an error). Supply a stable idempotencyKey and reuse it on every retry. The same key returns the original draft without editing it. Without a key, check z2h_list_my_listings before retrying. Source delivery, review and publishing continue in the web wizard.

z2h_get_listing

Read one owned listing before editing it. Requires listings:read. Use a slug from z2h_list_my_listings. Returns descriptions, pricing, software attributes, source attachment state and web edit links. Missing listings and listings owned by someone else both return not found. This does not download source code.

z2h_list_my_listings

Find the authenticated Builder's drafts and live listings before creating another draft. Requires listings:read. Returns items with slugs, publication state, USD prices, edit links, and nextCursor. Pass nextCursor to continue paging; null ends the list. An invalid or expired token requires sign-in again.

z2h_request_source_upload

For an owned draft, get a short-lived signed archive URL. Ask the Builder to explicitly accept this exact statement: "I own or have the rights to sell the codebase I am about to upload." Pass ownershipAccepted=true and ownershipVersion=2026-09-27 only after they accept. Returns signedUrl for the archive PUT, objectKey for confirmation, and contentType for the upload header. Keep signedUrl private. PUT up to 100 MB to signedUrl, then call z2h_confirm_source_upload. This does not publish.

z2h_search_marketplace

Find live software by keyword before building from scratch. Public, no sign-in needed. Returns descriptions, USD license prices, tech stacks and listing links. Example: {"search": "invoice", "limit": 5}. Empty search browses recent software. When hasMore is true without nextCursor, narrow the search. Matching is lexical. Errors set isError; retry a rate limit later. Use z2h_compare_marketplace_listings for a shortlist or z2h_show_marketplace for cards. A result does not guarantee suitability or purchase availability.

z2h_show_marketplace

Show public software cards and an interactive comparison panel. First search with z2h_search_marketplace, then pass the public slugs to display, and the search text you used as `search` so the panel shows what the cards are for. Without slugs, shows the newest live software. Prices and availability are refreshed on the server. Listing links open the Zero to Hundred website.

z2h_update_draft_listing

Update an owned draft. Omitted fields stay unchanged; nullable fields accept null to clear them. Live listings cannot be edited through this tool. Requires listings:write. Returns the draft identity, web edit/review links and warnings (quality advice about the saved draft, never an error). On conflict, read the listing again before retrying.

Zero to Hundred marketplace — questions

Answers built from our own checks of this server.

What can Zero to Hundred marketplace do?

It exposes 9 tools, read directly from the server on our last check. Among them: z2h_compare_marketplace_listings, z2h_confirm_source_upload, z2h_create_draft_listing, z2h_get_listing, z2h_list_my_listings, z2h_request_source_upload and 3 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Zero to Hundred marketplace working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 2 of 91 checks got a reply (2.2%), average response time 1505 ms. The bar chart above shows every period we have measured.

The registry lists Zero to Hundred marketplace as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Zero to Hundred marketplace?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Zero to Hundred marketplace need an API key?

No. Zero to Hundred marketplace completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Zero to Hundred marketplace?

It answers our handshake in 1505 ms on average, which is faster than 1% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Zero to Hundred marketplace open source?

We cannot say either way: 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
