Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

Remote (streamable-http)
Claude Code 
claude mcp add --transport http bridgenode-mcp 'https://bridgenode.cc/mcp'
JSON configuration (Claude Desktop, Cursor, VS Code)

@bridgenode/mcp

Built for AI agents — no API keys, no registration, pay-as-you-go with Solana USDC via x402. Start free: free models and 2 free calls on paid models per client, no wallet required.

BridgeNode MCP wrapper — stdio MCP server that proxies requests to the remote https://bridgenode.cc/mcp (streamable-HTTP) with automatic x402 payment (Solana USDC). No API keys, no registration.

Installation (one-command)

claude mcp add bridgenode -s user -- npx -y @bridgenode/mcp@latest

Or manually (Claude Code, Cursor, other MCP clients):

{
  "mcpServers": {
    "bridgenode": {
      "command": "npx",
      "args": ["-y", "@bridgenode/mcp@latest"]
    }
  }
}

Configuration (.env)

# Solana wallet private key (base58) — agent's payment wallet
# Optional — Solana wallet private key (base58). Needed only for PAID calls:
# free models and the 2 free trials work without it.
BRIDGENODE_WALLET_KEY=

# Spending policy (fail-closed)
BRIDGENODE_MAX_PER_CALL=0.05
BRIDGENODE_DAILY_CAP=1.0

Tools

  • chat_completions — AI inference (free models run without payment; the first 2 calls to a PAID model are free per client, then x402 payment is automatic). Accepts OpenAI-style tools / tool_choice — the model's answer then carries tool_calls (the wrapper passes arguments through unchanged)
  • list_models — model list (free)
  • get_price_estimate — estimate cost of a chat request (free)

How it works

  1. Local MCP client launches the wrapper via stdio
  2. Wrapper connects to https://bridgenode.cc/mcp (streamable HTTP)
  3. On tools/call receiving 402 (payment required) — the wrapper automatically signs the payment with BRIDGENODE_WALLET_KEY and retries the request
  4. Spending policy checks every payment BEFORE signing (fail-closed)
