Installation
There are two ways to install the ChainGPT Developer Kit for Claude Code: via the plugin installer (recommended) or via manual git clone.
Plugin install (recommended)
Run this command inside Claude Code:
/plugin install ChainGPT-org/chaingpt-claude-skill
This automatically sets up the skill files, configures the MCP server via .mcp.json, and makes all 5 skills and 12 MCP tools available immediately. The only additional step is setting your API key (see API Key Setup).
Manual install (git clone)
Clone the repository into your project's .claude/skills/ directory:
git clone https://github.com/ChainGPT-org/chaingpt-claude-skill .claude/skills/chaingpt
For a user-level install that applies to all projects, clone to your home directory instead:
git clone https://github.com/ChainGPT-org/chaingpt-claude-skill ~/.claude/skills/chaingpt
Configure the MCP server (manual installs only)
If you installed via git clone, you need to build the MCP server and add it to your settings:
cd .claude/skills/chaingpt/mcp-server
npm install && npm run build
Then add the following to your .claude/settings.json:
{
"mcpServers": {
"chaingpt": {
"command": "node",
"args": [".claude/skills/chaingpt/mcp-server/dist/index.js"],
"env": { "CHAINGPT_API_KEY": "your-key-here" }
}
}
}
What gets installed
After installation, the following components are available:
| Component | Description |
|---|---|
| 5 skills | Main API reference, playground, debug assistant, hackathon scaffolder, update manager |
| 12 MCP tools | Direct API access from Claude conversations |
| 16 reference docs | Complete API documentation for all 7 products |
| 10 templates | Production-ready project scaffolds |
| 45+ patterns | Audited Solidity smart contract patterns |
| 8 examples | Working code in JavaScript and Python |
| Mock server | Zero-credit local testing server |
Verifying the installation
Open Claude Code and ask it anything about ChainGPT:
"What ChainGPT products are available and how much do they cost?"
If the skill is loaded correctly, Claude will respond with detailed product information including exact credit costs, SDK package names, and endpoint URLs — not generic information from its training data.
Updating
To check for and apply updates, use the update skill inside Claude Code:
/chaingpt-update
This fetches the latest changes from GitHub and shows a changelog before applying. For manual installs, you can also run git pull in the skill directory.
