  "works": "Signed out in headless Chrome 155 (no captcha or bot wall), all of these work: home, marketplace (48 listings, 7 categories), category filters, listing pages, the itemized Trust Score breakdown, and copy-install. The breakdown is 0\u2013100 from six factors: provenance /25, license /15, publisher /20, adoption /15, satisfaction /15, maturity /10, each with a reason. Copy-install put the exact text on the clipboard: 'claude mcp add playwright-mcp -- npx -y @playwright/mcp', a Cursor mcpServers JSON, a VS Code servers/stdio JSON and the bare npx command. Homepage job chip 'drive a browser' showed 'Matched job: Drive a real browser' with Playwright MCP, Puppeteer MCP and fetch-mcp. Keyword search works ('browser' -> playwright-mcp, puppeteer-mcp; 'playwright', 'github' -> 1 each). Nonsense and unicode queries show a clean 'No tools found'. Public JSON API works without auth (verified by curl): GET /api/servers, /api/servers/:slug, /api/servers/:slug/trust, /api/discover, /api/stats, /api/categories. POST /api/scan {repo_url} runs a live source scan signed out in ~0.6\u20130.8 s: score, six factors (install hooks, credential theft, leaked secrets, tool-poisoning, obfuscation, dangerous surface) and file/line findings with masked previews. The meta-MCP npm package @mcpx-digital/mcp 0.1.1 ran over stdio (initialize, tools/list) and exposes search_servers, discover_servers, get_server, inspect_trust, scan_repo and install_server. search_servers('browser'), inspect_trust and get_server worked; an unknown slug returned isError 'Server not found'. Trust spot-check: license values match GitHub for microsoft/playwright-mcp (Apache-2.0) and github/github-mcp-server (MIT).",
  "breaks": "Search is a literal substring match, not job matching. The marketplace search for 'drive a browser' (one of the homepage's own chips) returns 0 tools, and so does the API and meta-MCP search_servers. Queries over 199 chars get HTTP 400 'Search query too long', but the UI then says 'Offline demo catalog. The live marketplace API is unreachable' (false message). Trust Scores barely differentiate: 39 of 48 listings score exactly 39 'caution'. Official Microsoft/GitHub listings say 'Community publisher \u2014 identity not yet reviewed', and adoption counts only MCPX installs (0), not GitHub stars (playwright-mcp 38.3k, github-mcp-server 33.7k). 0 of 48 listings have repo_verified true, so the meta-MCP install_server gate refuses every listing unless force=true (code reading, not run). GitHub MCP Server's copied configs use npx -y @modelcontextprotocol/server-github, which npm marks deprecated ('Package no longer supported'); the linked repo github/github-mcp-server is a Go server. The Claude tab labels 'claude mcp add \u2026' as 'adds to Claude Desktop automatically'; that is the Claude Code CLI command. The leaked-key scanner gives false positives: in modelcontextprotocol/servers-archived it flagged the README placeholder 'xoxb-your-bot-token' twice as a leaked Slack token, and in HernanJr0/brain-graph a regex .exec() in src/colors.ts as a dangerous exec() call. Listing pages store only a tier for 14/48 listings (scan field null for the rest, e.g. playwright-mcp, github-mcp-server), and there is no scan UI on the site (/scan renders an empty page). Footer/docs links point to github.com/TheoryofShadows/Mcp, which returns 404 (repo missing or private); /docs redirects there. Counts disagree: site footer and /api/stats say 49 servers, marketplace says 48. Sign-in is demanded when you click 'Install Tool' on a listing (-> /login?next=%2Ftool%2Fplaywright-mcp), even for free tools (homepage says 'Free tools need no account'), and when you open /submit (Publish) (-> /login). /dashboard shows demo data with 'Sign in to see your real metrics'; /api/auth/me returns 401. Did not sign in, submit the Report form, buy the paid Railway listing, or run install_server.",

I downloaded the @mcpx-digital/mcp tarball from npm, read its source, and ran it over stdio under a scratch dir with a fake HOME (read-only tools only). Trust fields were spot-checked against the GitHub API and npm registry. Edge cases: nonsense, unicode, and 3,000-char queries plus a length bisect. No account, no credentials.",
