Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog) Scored 2026-10-18. - **Endpoint Security**: 66/100 - The endpoint's TLS certificate is valid, in date, and uses a strong key. - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (z2h_create_draft_listing). - HTTPS is enforced; there's no plaintext access path. - The HSTS (Strict-Transport-Security) header is present. - DNSSEC is configured correctly; the domain's records validate against the full chain to the root. - **Transport & Reachability**: 100/100 - Verified streamable-http transport via a live MCP handshake. - **Schema Quality & AI Usability**: 75/100 - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name). - AI-judged instruction clarity (excellent). - Context-footprint check failed: tool/resource definitions use about 2609 tokens (~260/item across 10 items; 9 tools + 1 resources), over budget; trim descriptions and params. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 7/100 - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses. - **Tool Coverage**: 100/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 100% of tool parameters carry a description. - Structured output schemas are declared (100% of tools); any adoption earns full credit. - **Tool Safety**: 100/100 - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured. - We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation. - An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it. - **Capabilities**: 100/100 - Implements a current MCP spec version (2026-07-28). - Supports UI / widget rendering. ## Install ### How do I install the Zero to Hundred marketplace MCP server? Zero to Hundred marketplace is a hosted endpoint at https://zerotohundred.ai/api/mcp, 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. ### Claude ```bash claude mcp add --transport http zerotohundred-admin-marketplace 'https://zerotohundred.ai/api/mcp' ``` ### Cursor ```json { "mcpServers": { "zerotohundred-admin-marketplace": { "url": "https://zerotohundred.ai/api/mcp" } } } ``` ### VS Code ```json { "servers": { "zerotohundred-admin-marketplace": { "type": "http", "url": "https://zerotohundred.ai/api/mcp" } } } ``` ### Codex ```toml [mcp_servers.zerotohundred-admin-marketplace] url = "https://zerotohundred.ai/api/mcp" ``` ### opencode ```json { "$schema": "https://opencode.ai/config.json", "mcp": { "zerotohundred-admin-marketplace": { "type": "remote", "url": "https://zerotohundred.ai/api/mcp", "enabled": true } } } ``` ### OpenClaw ```bash openclaw mcp add zerotohundred-admin-marketplace --url 'https://zerotohundred.ai/api/mcp' --transport streamable-http ``` ### Hermes ```yaml mcp_servers: zerotohundred-admin-marketplace: url: "https://zerotohundred.ai/api/mcp" ``` ### Netclaw ```json { "McpServers": { "zerotohundred-admin-marketplace": { "Transport": "http", "Url": "https://zerotohundred.ai/api/mcp" } } } ``` ### Vellum ```bash assistant mcp add zerotohundred-admin-marketplace -t streamable-http -u 'https://zerotohundred.ai/api/mcp' ``` ### Other ```json { "mcpServers": { "zerotohundred-admin-marketplace": { "type": "http", "url": "https://zerotohundred.ai/api/mcp" } } } ``` The mcpServers block is a cross-client convention.

Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims. ### 2026-10-18 (score 69, +1) 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.

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. Input parameters: - `cursor` (string): Opaque nextCursor from the previous page. Keep the same filters and sort. - `domains` (array): Industry tags for the software. Choose keys from the Zero to Hundred taxonomy: ai, analytics, art-design, auth-identity, cms, conference, developer-tools, devops, e-commerce-marketplace, education, e… - `limit` (integer): Number of listings to return in this page. Omission uses 20. - `mode` (array): Filter by the listing's sale model. Omission leaves the sale model unfiltered. - `operatingStatus` (array): Filter by software readiness or existing commercial operation, rather than listing publication state. - `search` (string): Keywords describing the software the Buyer needs. - `sort` (string): Result order. Defaults to relevance for a search, otherwise newest. - `type` (array): Categories matching the kind of software the Buyer wants. Omission searches across categories.

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.
