ChainGPT Developer Kit for Claude Code

The only Claude Code skill that turns your AI assistant into a Web3 engineering co-pilot.

Full API reference. 12 MCP tools. 45+ Solidity patterns. 10 project templates. Zero context-switching.

The Problem

Building with Web3 AI APIs means constantly switching between docs, SDKs, and Stack Overflow. You paste an endpoint, get the params wrong, burn credits debugging, and repeat.

This skill fixes that. Install it once and Claude already knows every ChainGPT endpoint, parameter, credit cost, and best practice — so you just describe what you want built.

Demo

You:  "Generate an NFT of a cyberpunk samurai and mint it on Polygon"

Claude: I'll use the ChainGPT NFT Generator to create your image and mint it on-chain.

       1. Generating image with VisionaryForge model... ✓
       2. Queuing for on-chain minting on Polygon (chainId: 137)... ✓
       3. Polling for completion... ✓

       ✅ NFT minted successfully!
       Collection ID: cgpt-a8f3...
       Token URI: ipfs://QmX7k...
       View on PolygonScan →

       Cost: 2 credits ($0.02)

No docs. No boilerplate. Just results.

⚡ Quickstart

One command. That's it.

Claude Code (plugin install):

/plugin install ChainGPT-org/chaingpt-claude-skill

Manual install (git clone):

git clone https://github.com/ChainGPT-org/chaingpt-claude-skill .claude/skills/chaingpt

[!TIP] For user-level install (all projects): clone to ~/.claude/skills/chaingpt instead.

Now open Claude Code and ask it anything about ChainGPT — it just works.

🧰 What You Get

📖 Complete API Reference

Every endpoint, parameter, and response format for all 7 products — with real API response examples, credit costs, and SDK snippets in JS + Python.

🤖 12 MCP Tools

Claude doesn't just write code — it calls the APIs directly. Generate images, mint NFTs, audit contracts, fetch news — all from the chat.

📋 10 Project Templates

Production-ready scaffolds for Next.js, React Native, Express, Nuxt, and more. Multi-product compositions included.

🔐 45+ Solidity Patterns

Audited, battle-tested smart contract patterns Claude composes from — ERC-20 variants, NFTs, DeFi, governance, security.

🧪 79 Passing Tests

53 MCP server unit tests + 26 mock server endpoint tests. CI-ready out of the box.

🛠️ Developer Tools

Interactive playground, debug assistant, hackathon scaffolder, cost estimator, and migration guides from OpenAI/Alchemy.

🔌 MCP Server — 12 Tools

The MCP server gives Claude direct API access — not just code generation:

If installed via /plugin install, the MCP server is configured automatically via .mcp.json. Just set your API key:

export CHAINGPT_API_KEY="your-key-here"

For manual installs, build and configure:

cd .claude/skills/chaingpt/mcp-server
npm install && npm run build

Add to .claude/settings.json:

{
  "mcpServers": {
    "chaingpt": {
      "command": "node",
      "args": [".claude/skills/chaingpt/mcp-server/dist/index.js"],
      "env": { "CHAINGPT_API_KEY": "your-key-here" }
    }
  }
}

📋 10 Project Templates

🔐 45+ Smart Contract Patterns

Audited, production-ready Solidity patterns Claude composes from instead of generating from scratch:

💬 Usage Examples

Just talk to Claude naturally:

"Build me a Web3 AI chatbot with streaming responses"

"Generate and mint an NFT on BSC using ChainGPT"

"Set up smart contract auditing in my CI/CD pipeline"

"Scaffold an NFT marketplace that uses 4 ChainGPT products"

"What's the credit cost for generating 100 NFTs with NebulaForge XL?"

"Write a staking contract"  →  uses patterns library, not from scratch

"I'm migrating from OpenAI — help me switch to ChainGPT"

"I'm at a hackathon — scaffold me a DeFi project fast"

🧪 Testing

Use the mock server to develop and test without spending a single credit.

The mock server is a full drop-in replacement for the ChainGPT API — realistic responses, simulated latency, credit tracking — so you can build, iterate, and run CI/CD pipelines without touching your API quota.

Start the mock server

cd .claude/skills/chaingpt/mock-server
npm install && npm run dev
# → http://localhost:3001

Point your CHAINGPT_BASE_URL at http://localhost:3001 and everything works exactly as it would in production. No API key required.

Run the full test suite

79 tests passing across two suites:

# MCP Server tests (53 tests)
cd mcp-server && npm install && npm test

# Mock Server tests (26 tests)
cd mock-server && npm install && npm test

# Skill validation (118 structural checks)
bash scripts/validate.sh

The CI workflow (.github/workflows/ci.yml) runs all three automatically on every push and pull request.
