What is MarketNow?

MarketNow is the trust layer for agent commerce. Discovery is solved (MCP registry, Smithery, Glama); trust is not. MarketNow provides:

• Sentinel L1.5 security audit on every skill (6-point MCP security scan)
• review_status on every skill: auto-scanned (8,517) | human-reviewed (43) | maintainer-verified (0)
• Declared permissions per skill (network, filesystem, env_vars, subprocess)
• AP2-compatible mandates — human-in-the-loop by default, silent mode requires explicit opt-in
• x402 payments — HTTP 402 Payment Required protocol, USDC on Base
• Public audit log — every mandate transaction is a git commit

Install

npm install -g marketnow-mcp

Or use directly with npx (no install needed):

npx marketnow-mcp

Configuration

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "marketnow": {
      "command": "npx",
      "args": ["-y", "marketnow-mcp"]
    }
  }
}

Cursor

Add to Settings → MCP:

{
  "mcpServers": {
    "marketnow": {
      "command": "npx",
      "args": ["-y", "marketnow-mcp"]
    }
  }
}

Cline / VS Code

Add to your MCP config:

{
  "mcpServers": {
    "marketnow": {
      "command": "npx",
      "args": ["-y", "marketnow-mcp"],
      "env": {}
    }
  }
}

Tools Exposed

Tool	Description
search_skills	Search skills by query, category, or max price
get_skill	Get full details of a specific skill
list_categories	List all 25 categories with counts
get_manifest	Get marketplace metadata (totals, pricing)
get_install_command	Get the npx install command for a skill

Example Usage

Once connected, you can ask Claude:

• "Find me a skill to scrape websites and extract prices"
• "What's the cheapest AI/ML skill on MarketNow?"
• "Show me all skills in the Security category"
• "Get the install command for mn-ai-00001"

Claude will use the MarketNow MCP server to search the marketplace and return results with prices, descriptions, and install commands.

How It Works

The MCP server fetches the public API at https://marketnow.site/api/skills.json (cached for 1 hour). It exposes 5 tools that agents can call to discover skills without leaving their runtime.

• No API key required for read operations
• CORS-enabled — works from browser and Node.js
• 1-hour cache — minimizes bandwidth and latency
• 5,000+ skills — the largest curated MCP skill catalog

To purchase a skill, the agent opens the buy URL in a browser.

Pricing

All skills on MarketNow are micro-priced:

• $0.99 — utility, single-function MCP servers
• $1.99 — standard integrations
• $2.99 — multi-feature tools (most common)
• $4.99 — sophisticated multi-endpoint tools
• $9.99 — enterprise-grade, specialized

Average price: $2.50. One-time payment, lifetime license. No subscriptions.
