Description, as the server wrote it: ```untrusted-server-text 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` - The name "z2h_create_draft_listing" says "create": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text 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 and web edit/review links. 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_request_source_upload` - The name "z2h_request_source_upload" says "request": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text 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_update_draft_listing` - The name "z2h_update_draft_listing" says "update": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text 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 and web edit/review links. On conflict, read the listing again before retrying. ``` ## Only reads (5) Looks things up and changes nothing. Claude Code: allow. ### `z2h_compare_marketplace_listings` - The name "z2h_compare_marketplace_listings" says "compare": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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_get_listing` - The name "z2h_get_listing" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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` - The name "z2h_list_my_listings" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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_search_marketplace` - The name "z2h_search_marketplace" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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` - The name "z2h_show_marketplace" says "show": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `marketplace`: ```json { "permissions": { "allow": [ "mcp__marketplace__z2h_search_marketplace", "mcp__marketplace__z2h_list_my_listings", "mcp__marketplace__z2h_get_listing", "mcp__marketplace__z2h_compare_marketplace_listings", "mcp__marketplace__z2h_show_marketplace" ], "ask": [], "deny": [ "mcp__marketplace__z2h_create_draft_listing", "mcp__marketplace__z2h_update_draft_listing", "mcp__marketplace__z2h_request_source_upload", "mcp__marketplace__z2h_confirm_source_upload" ] } } ```
