MarketNow is the open marketplace for MCP-compatible agent skills. It allows any agent (Claude Desktop, Cursor, Cline, VS Code) to search, discover, and install Sentinel-certified skills via the Model Context Protocol.
The code is open source. What you pay for is trust, certification, and integration.
๐ก๏ธ Sentinel Certification
Every skill in MarketNow is audited by Sentinel, a 6-layer security pipeline:
L1.5 โ Metadata Checks (real-time, ~200ms on Vercel)
L2 v2.0 โ Active MCP Probe + Docker Sandbox (async via GitHub Actions)
L2.5 adds gVisor (runsc) userspace kernel isolation on top of Docker. The MCP server never touches the host kernel.
Runs the actual MCP server in isolation:
L2 coverage: 206 of 7,063 skills have L2.5 gVisor sandbox results. The remaining 8,558 are certified with L1.5+L1.6 (static analysis). L2 coverage grows weekly via automated GitHub Actions.
Each skill gets a signed SHA-256 certificate with:
certificate_id (MN-SC-2026-XXXXXXX)
overall_score (0-10)
risk_level (low/medium/high/critical)
7-day validity (regenerated weekly by GitHub Actions cron)

๐ฐ Business model โ Sentinel subscriptions for sellers, free marketplace for everyone else
MarketNow does NOT sell skills. We administer a free marketplace of 7,063 MCP servers. All skills are free to install and use.
Our revenue comes from sellers who want to list/sell THEIR skills on MarketNow. They subscribe to Sentinel (the security audit pipeline) and we take a commission on each sale.
