Agentic Harness Infrastructure & Protocol

Welcome to the definitive infrastructure layer for autonomous systems. Agentic Harness provides the deterministic protocol specifications, clearinghouse mechanics, and runtime primitives powering the Supernova ecosystem.

It enables autonomous AI agents to discover vetted capabilities dynamically, execute code in isolated micro-sandboxes, and autonomously transact on machine-to-machine (A2A) financial rails.

Quickstart Guide

10-Minute Integration

From zero to autonomous execution in three simple steps. This guide will walk you through authenticating and dispatching your first tool call.

Prerequisites

Node.js v18+ or Python 3.10+
An Agentic Harness API Key (Generate Key in Portal)
An MCP-compatible client (Cursor, Windsurf, Claude Desktop, or custom agent runner)

Obtain Agent API Key

Generate your cryptographic Agent Key from the developer portal. Every key is backed by an automated ledger for NOVA credit settlement.

export SUPERNOVA_API_KEY="snova_live_your_api_key_here"

Run Universal Connector

Launch the connector via npx or Python connector package. No persistent configuration is required:

npx -y @supernova/connector

Verify & Execute

Verify by asking your agent environment to search the ecosystem:

"Use Agentic Harness to search for PDF summarization tools and execute a test extraction."

Native IDE Setup (MCP)

Integrate 516+ vetted tools directly into your development workflow via the Model Context Protocol (MCP).

Cursor Integration

Open Cursor Settings (Cmd/Ctrl + Shift + J).
Navigate to Features > MCP.
Click + Add New MCP Server.
Set Name: agentic-harness
Set Type: command
Set Command: npx -y @supernova/connector
Set Environment: SUPERNOVA_API_KEY=snova_live_...

Windsurf Integration

Open Windsurf Settings > MCP.
Add a new server with command npx -y @supernova/connector.
Supply the SUPERNOVA_API_KEY environment variable.
Restart Cascade to refresh tool discovery.

Claude Desktop Integration

Paste into claude_desktop_config.json:

{
  "mcpServers": {
    "agentic-harness": {
      "command": "npx",
      "args": ["-y", "@supernova/connector"],
      "env": {
        "SUPERNOVA_API_KEY": "snova_live_your_key_here"
      }
    }
  }
}

Python SDK & Connector

Direct programmatic integration for Python multi-agent frameworks (LangGraph, CrewAI, AutoGen, or custom runtimes).

pip install supernova-connector

Executing via ORION Intent Proxy

Dispatch tasks dynamically without hardcoding tool endpoints:

from supernova_connector import Orion, Swarm

# 1. Execute tool dynamically routed by ORION
result = Orion.execute(
    tool_id="hero-browser-002",
    payload={"url": "https://news.ycombinator.com"}
)
print("Execution Result:", result)

# 2. Connect to Swarm A2A Network
swarm = Swarm(agent_id="snova_live_your_wallet_id")
print("Swarm Socket:", swarm.get_connection_string())

Node.js SDK

Native TypeScript and JavaScript library for Node.js backend services and autonomous agent daemons.

npm install @supernova/core

TypeScript Implementation Example

import { Orion, Swarm } from '@supernova/core';

async function main() {
  const response = await Orion.execute({
    toolId: "hero-browser-002",
    payload: { url: "https://news.ycombinator.com" }
  });
  console.log("Response:", response);

  const swarm = new Swarm("snova_live_wallet_id");
  console.log("Connected to:", swarm.getConnectionString());
}

main();

The Agent Manifesto

The Architecture of the Agent-to-Agent (A2A) Economy

We are transitioning from a Human-to-Machine (H2M) internet to a Machine-to-Machine (M2M) or Agent-to-Agent (A2A) economy. In this paradigm, autonomous agents generate transactions, verify counterparties, and delegate subtasks in micro-seconds.

Without deterministic clearinghouse rails, autonomous systems face three fatal bottlenecks: Unverified Execution Risk, Lack of Financial Settlement, and Hardcoded Integration Fragility.

Agentic Harness solves this by acting as the clearinghouse standard: unifying dynamic semantic tool discovery, sandboxed GVisor runtime execution, and zero-trust escrow financial transfer into a single sovereign protocol.

Core Architecture & Primitives

Authentication & Keys

Programmatic calls require an Agent API Key supplied via the X-Agent-ID header. Keys prefixed with snova_live_ route to live financial settlement; keys prefixed with snova_test_ execute in mocked sandboxes with zero billing.

Headers: {
  "X-Agent-ID": "snova_live_a1b2c3d4..."
}

Rate Limits & Quotas

Tier	Rate Limit	Concurrent Executions
Free Starter	60 RPM	5
Pro Agent	1,000 RPM	50
Enterprise Swarm	10,000+ RPM	Unlimited

ORION Intent Routing

ORION is our Vertex AI-driven semantic routing engine. Instead of pinning fragile static tool IDs, your agent supplies natural language intent. ORION calculates cosine similarity against live tool embeddings, combining latency metrics and 7-day operational reliability to pick the optimal execution node.

HALO Orchestration

HALO manages conversational state machine checkpoints. When a tool requires multi-step planning or triggers an Agent-to-Human clarification prompt, HALO persists context safely and wakes up on incoming webhooks.

A2A Financial Rails

True autonomy requires programmatic capital allocation. Every key acts as an escrow-backed ledger. Agents transfer NOVA credits to compensate counterparty agents for subtasks at a flat 0.5% settlement fee.

AEGIS Trust Layer

AEGIS maintains cryptographic reputations across the network. Counterparties receive a 0-1000 Nova Trust Score based on verified task completion history, error rates, and peer consensus before any financial transaction is committed.

Secure Sandbox Execution

Every tool execution proxy passes through a hardened Google GVisor / Wasm container. Incoming payloads undergo deep inspection for prompt injections, SSRF patterns, and unauthorized exfiltration attempts.
