x402-mcp

MCP server bringing hundreds of x402-paid APIs to AI agents (Claude, Cursor, MCP-aware clients). Auto-discovers tools from CDP Bazaar; handles USDC micropayments on Base + Solana.

Features

Auto-discovers x402 endpoints from CDP Bazaar (no hard-coded list)
Reads metadata directly from Bazaar (description, schema, pricing)
Refreshes every 5 min — new endpoints appear without restart
Handles HTTP 402 + USDC payment automatically
Multi-chain: Base + Solana mainnet live (USDC on both); Polygon/BNB/EVM expandable

Related MCP server: x402-bazaar-mcp

Install (Claude Desktop)

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "x402-mcp": {
      "command": "npx",
      "args": ["-y", "x402node-mcp"],
      "env": { "X402_PRIVATE_KEY": "0xYOUR_BASE_PRIVATE_KEY" }
    }
  }
}

Set X402_PRIVATE_KEY to a Base EOA private key (hex, 0x-prefixed) with USDC on Base mainnet (Solana payment via SPL USDC also supported). Restart Claude Desktop. The server auto-discovers ~117 tools on first run.

Cost Safety

Each tool call costs $0.0001-$0.10 USDC depending on endpoint
Hard cap: MAX_PRICE_USD env var (default $0.10/call); calls above are blocked
Use a fresh burner wallet, not your main wallet

How it works

Agent calls tool -> HTTP 402 -> x402-fetch signs EIP-3009 -> CDP Facilitator settles on Base or Solana -> response returned. Buyer pays no gas.

TDQS

C2.9/5.0

Scored 2026-05-27 02:10 across 117 tools

Disambiguation3/5

Tools are grouped into distinct domains (cn402 Chinese culture, x402node utilities), but within these groups many tools have overlapping purposes, such as multiple BaZi endpoints and two color palette generators. Descriptions are detailed enough to distinguish most tools, but some near-duplicates (e.g., cn402_today vs cn402_festival_today) cause confusion.

Naming Consistency4/5

Two clear prefixes (cn402_ and x402node_) with a consistent category_function pattern. Most tools follow this, but exceptions like x402node_generate_color-palette (vs x402node_color_palette) and hyphenated names (email-security) slightly reduce consistency.

Tool Count1/5

117 tools is far too many for a single MCP server, indicating a lack of focus. The server mixes Chinese culture, general utilities, cryptography, etc., resembling a collection rather than a cohesive service. Typically 3-15 tools per server is appropriate; this is extreme overreach.

Completeness4/5

Despite the large count, the server covers a vast range of functionality comprehensively, especially Chinese culture (BaZi, Feng Shui, I Ching, etc.) and developer utilities (crypto, text, URL, validation). There are few obvious gaps within each subdomain, though the overall surface is bloated.
