Corbel Blue SDK (@corbel-blue/sdk)

Official client library and Model Context Protocol (MCP) server for Corbel Blue (https://corbel.blue), providing hardware-isolated silicon enclaves, cryptographic attestation verification, and x402 settlement rails for autonomous AI agents.

⚡ Global Developer Beta Schedule

Important Launch Notice: The Corbel Blue Global Developer Beta opens on October 1, 2026. You can install the SDK, configure your Model Context Protocol (MCP) clients, inspect TypeScript typings, and pre-register your sandbox API keys starting today. Live bare-metal hardware enclaves (Intel TDX / AMD SEV-SNP) and automated clearing rails unlock on October 1st.

📦 Installation

npm install @corbel-blue/sdk

Or using pnpm / yarn:

pnpm add @corbel-blue/sdk
yarn add @corbel-blue/sdk

🤖 Model Context Protocol (MCP) Integration

Corbel Blue features native support for the open Model Context Protocol (MCP), allowing LLMs (Claude Desktop, Cursor, Gemini, AutoGen, CrewAI, LangChain) to spawn hardware enclaves and settle payments directly via standard JSON-RPC 2.0 stdio tools.

Claude Desktop Configuration

Add Corbel Blue to your claude_desktop_config.json:

{
  "mcpServers": {
    "corbel-blue": {
      "command": "npx",
      "args": ["-y", "@corbel-blue/sdk"]
    }
  }
}

Cursor / Windsurf Configuration

Add Corbel Blue to your MCP settings file:

{
  "mcpServers": {
    "corbel-blue": {
      "command": "npx",
      "args": ["-y", "@corbel-blue/sdk"]
    }
  }
}

Available MCP Tools

| Tool | Description | |---|---| | corbel_provision_sandbox | Pre-provisions a free developer sandbox API key with 100,000 monthly requests. | | corbel_enclave_spawn | Requests an isolated silicon hardware enclave (intel-tdx, amd-sev-snp, nvidia-cc). | | corbel_enclave_attest | Verifies hardware attestation measurements confirming untampered execution. | | corbel_micro_clear | Clears high-speed machine micro-payments across multi-rail settlement networks. | | corbel_check_quota | Inspects remaining monthly requests, latency telemetry, and rate limits. | | corbel_evidence_verify | Validates on-chain immutable evidence references (x402ev/1). |

🚀 TypeScript Quickstart

1. Pre-Provision a Sandbox Key

import { CorbelClient } from '@corbel-blue/sdk';

const client = new CorbelClient();

const sandbox = await client.provisionSandbox({
    agentName: 'autonomous-alpha-trader',
    useCase: 'autonomous-agent',
});

console.log('Sandbox Key:', sandbox.apiKey);
console.log('Launch Date:', sandbox.publicBetaLaunch);
// Output:
// Sandbox Key: crb_test_...
// Launch Date: 2026-10-01

2. Check Launch Status & Quota

import { CorbelClient, isPreLaunch, getPreLaunchStatus } from '@corbel-blue/sdk';

console.log('Pre-Launch Active:', isPreLaunch());
console.log(getPreLaunchStatus());

const client = new CorbelClient({ apiKey: 'crb_test_your_key_here' });
const quota = await client.checkQuota();

console.log('Remaining Requests:', quota.remainingRequests);

3. Verify Hardware Attestation Quotes

import { CorbelClient } from '@corbel-blue/sdk';

const client = new CorbelClient({ apiKey: 'crb_test_your_key_here' });

const attestation = await client.verifyAttestation({
    sessionId: 'sess_intel_tdx_1a2b3c4d',
});

console.log('Silicon Vendor:', attestation.siliconVendor);
console.log('Verdict:', attestation.verdict);

🛡️ Architecture & Security

• Strict Non-Custodial Operation: Corrente Labs does not custody, transmit, pool, or manage customer funds.
• Hardware Isolation: Silicon-level memory encryption physically segregates in-flight agent code and confidential data from host environments.
• Cryptographic Measurement: Cryptographic measurement quotes verify unmodified execution prior to settlement triggering.
• Zero Counterparty Gas Overhead: Two-phase decoupled clearing ensures autonomous workflows never trap capital or suffer pre-settlement failure penalties.
