Common Workflows
Full-Stack Web3 App
1Ask Cline to scaffold a Next.js app with GoldRush integration
2It creates project structure, installs dependencies, and configures SDK
3Cline builds API routes and React components for blockchain data
4It runs the dev server and tests the integration in the browser
Test-Driven Blockchain Development
1Ask Cline to write tests for GoldRush API integration
2It creates test files with proper mocking of API responses
3Cline runs the tests and iterates until they pass
Autonomous Data Pipeline
1Describe a data pipeline that processes onchain events
2Cline builds the pipeline with GoldRush API integration
3It executes the pipeline in the terminal and shows results
4Cline iterates on failures autonomously
End-to-End Feature Development
1Ask Cline to add wallet analytics to your existing app
2It analyzes your codebase, adds GoldRush SDK, creates components
3Cline runs the app and uses browser automation to verify the feature
Tips for Success
Cline has built-in MCP support. Just add the server config in the Cline MCP settings
Let Cline run terminal commands to install dependencies and test code
Cline can use the browser to visually verify your blockchain UI
Approve tool calls carefully. Cline has full file system and terminal access
Cline FAQ
Cline is open-source and free. You bring your own API key for the underlying LLM (Claude, GPT, etc.) and the GoldRush API key for onchain data.
Troubleshooting
MCP Server not showing in ClineOpen Cline settings (gear icon in the Cline panel) and navigate to MCP Servers. Add the GoldRush configuration there, not in VS Code's general settings.
Cline not finding GoldRush toolsRestart VS Code after adding the MCP server. Check the Cline output channel for connection errors. Ensure npx is in your PATH.
Permission errors when running commandsCline requires approval for file writes and terminal commands. Click 'Allow' when prompted, or enable auto-approval for trusted commands in Cline settings.
