MarketNow — Trust Layer for Agent Commerce (MCP Marketplace)

Created By

Edison Flores2 months ago

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).

Zhipu Web Search

@BigModel

Zhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.

Concordance

@matharrismma

Language models generate; Concordance verifies. The verify tool checks a claim deterministically (no model in the loop) and returns HOLDS / BROKEN / INCOMPLETE with the worked reasoning and a sealed receipt (content_hash + cite_url) that re-fetches byte-identical or not at all. Also: ranked search over an ~11k-record library, seal_fetch to re-verify any receipt, redact to strip PII before text travels, and a sealed connection graph. Runs sovereign/offline too (stdlib-first Python). A public false-positive benchmark covers every domain: the engine has never sealed a falsehood. 38 tools live; remote endpoint at https://narrowhighway.com/mcp.
