0G Agent Kit

MCP88 tools · 0GGitHub

MCP-based toolkit for interacting with the 0G blockchain through AI agents or terminal. Stake, send transactions, deploy & verify contracts, and explore the chain, DA & storage — all from a single workspace.

Two ways to use

Subscription

Free

Connect MCP to Claude Code, Cursor, or Codex and use your existing subscription. No API key needed.

  • Claude Code auto-detects .mcp.json
  • Built-in /wallet, /send, /deploy skills
  • Works with Claude Pro/Max or Cursor Pro

AI SDK

Developers

Build programmatic agents via Vercel AI SDK with Claude or OpenAI. Full control over agent behavior.

  • Vercel AI SDK integration
  • Claude and OpenAI support
  • Ready-to-run demos included

Quick Start

Claude CodeClaude Code auto-detects .mcp.json and connects to 0G. Use built-in skills:

Architecture

The AI agent sees only your wallet address and tool results — never the private key. Signing always happens locally before the transaction is broadcast.

Security

Key Principle

The private key never leaves your machine. MCP prepares unsigned transactions, signing happens locally, then the signed transaction is broadcast back through MCP.

Simple Mode

Default

Private key stored in .env, protected by guard hooks that block the AI agent from reading it. Tests cover 26+ attack vectors.

Secure Mode

Maximum security

Private key encrypted in keystore, decrypted only in a separate daemon process. The AI agent physically cannot access the key — it only receives the signed hash.

Docker Isolation

Supply chain protection

Run all npm installs and demos inside a container. Node modules are isolated — compromised packages can't reach your host filesystem or keys.
