MarketNow — Trust Layer for Agent Commerce (MCP Marketplace)

The trust layer for agent commerce. 8,560 MCP-compatible skills with Sentinel L2 security audits, x402 payments (HTTP 402 + USDC on Base), and AP2 delegated mandates with human-in-the-loop by default. NOT another discovery registry — discovery is solved (MCP Registry, Smithery, Glama). MarketNow solves TRUST: every skill carries a Sentinel security report, declared permissions, and an honest review_status (auto-scanned | human-reviewed | maintainer-verified). ## What's different - 🔒 Sentinel L2: real-time security audit on every skill (18 Semgrep rules + Docker sandbox + OSV dependency check) - 💳 x402 + USDC on Base: HTTP 402 Payment Required, on-chain verifiable - 🛡️ AP2 mandates: agents buy autonomously, but human-in-the-loop is the DEFAULT (not opt-out) - 📜 Audit log = git commits: every mandate transaction is a public commit in the GitHub repo - 🌍 5 languages: EN, ES, ZH, PT, FR - 💰 $0.99–$9.99 one-time, 43 free skills, NO subscriptions - 🏢 Built by AliceLabs LLC (Wyoming, USA, 2025), solo founder Edison Flores, no investors ## MCP Tools - search_skills: Search by query, category, price, language - get_skill: Get full details (system prompt, sentinel, setup) - list_categories: 58 categories with counts - get_manifest: Marketplace metadata - get_install_command: Get npx install command ## Server Config { "mcpServers": { "marketnow": { "url": "https://marketnow.site/api/mcp" } } } ## Stats (live) - 8,560 MCP skills indexed - 58 categories - 43 free skills - 5 languages - License: MNNC-1.0 (source-available, non-commercial) ## Links - Website: https://marketnow.site - Trust roadmap: https://marketnow.site/trust - Standards: https://marketnow.site/standards - Source: https://github.com/edgarfloresguerra2011-a11y/marketnow - npm: https://www.npmjs.com/package/marketnow-mcp - OpenAPI: https://marketnow.site/api/openapi.json Built for autonomous agents. Every skill has a Sentinel security report, a ready-to-use system prompt, and auto-configured install. What you pay for is trust, curation, and integration — not the code (which is open source).
