Logicnodes Mcp Bridge MCP Server

@logicnodez/mcp-bridge

Connect any MCP-compatible AI agent (Claude Desktop, Cursor, Windsurf, Cline, etc.) to the LogicNodes x402 marketplace — 619 pay-per-call deterministic microservices.

Install

Node / MCP

npx -y @logicnodez/mcp-bridge

Python SDK

pip install logicnodes-m2m

from logicnodes_sdk import LogicNodesClient

client = LogicNodesClient()
result = await client.call_worker("fraud_detection_oracle", {
    "amount_usd": 9500,
    "transactions_last_1h": 7,
    "country_mismatch": True
})

No API key needed. The bridge uses the x402 protocol — your agent's wallet pays per call automatically.

Claude Desktop config

No-account mode (default)

No signup, no API key required. Your agent pays directly on-chain via x402:

{
  "mcpServers": {
    "logicnodes": {
      "command": "npx",
      "args": ["-y", "@logicnodez/mcp-bridge"]
    }
  }
}

With API key (optional — prepay / volume discounts)

{
  "mcpServers": {
    "logicnodes": {
      "command": "npx",
      "args": ["-y", "@logicnodez/mcp-bridge"],
      "env": {
        "LOGICNODES_API_KEY": "your-key-here"
      }
    }
  }
}

Get an optional API key at logicnodes.io if you prefer prepay billing.

How payment works

LogicNodes uses the x402 payment protocol. When your agent calls a service:

1. The hub returns HTTP 402 with a payment requirement
2. The MCP bridge pays the exact micro-amount on-chain (Base USDC by default)
3. The call completes — no accounts, no subscriptions, no prepay required

No account is ever required. The API key is purely optional for users who prefer a prepay balance.

Attested Execution (coming soon)

Select LogicNodes workers run inside AWS Nitro Enclaves — isolated VMs with no network, no storage, and no SSH access. Every response includes a cryptographically signed attestation document from the AWS Nitro Secure Module, proving:

• The exact code that produced the result (PCR2 hash)
• The exact kernel it ran on (PCR1 hash)
• The exact enclave image (PCR0 hash)
• A timestamp and nonce binding the attestation to your specific request

PCR measurements are published on-chain (Base mainnet) after each deployment, so anyone can verify without trusting LogicNodes.

This is the infrastructure behind the "mathematically unhackable" claim — not marketing, just math.
