Helius MCP: AI-Powered Solana Development Documentation
Connect AI tools directly to Helius Solana API documentation for intelligent code generation and contextual development assistance.
AI-Native Development: Use the Helius MCP server to give AI tools access to our documentation, enabling contextual code generation and intelligent assistance.
What is MCP?
Model Context Protocol (MCP) is a standard that allows AI applications to access external documentation and data sources. Think of it as a bridge that lets AI tools like Claude, Cursor, and Windsurf read your documentation in real-time to provide better, more accurate assistance.
Real-time Context
AI tools can query live documentation and API specifications for accurate, up-to-date information
Code Generation
AI generates working code examples using current API methods and best practices from our docs
Interactive Development
Ask questions about Helius APIs and get contextual answers based on our documentation
Seamless Integration
Works with popular AI-powered IDEs and development tools
How Helius MCP Works
The Helius MCP server automatically provides AI tools with access to:
- Complete API Documentation: All Helius API methods, parameters, and examples
- Code Examples: Working implementations for common use cases
- Best Practices: Recommended patterns for using Helius services
- Real-time Updates: Always current with the latest documentation changes
Automatic Generation: Our MCP server is automatically generated from our documentation and API specifications, ensuring it’s always up-to-date with the latest features and changes.
Getting Started
Install MCP Support
First, make sure your AI tool supports MCP. Popular options include:
- Cursor: Built-in MCP support
- Windsurf: Native MCP integration
- Claude Desktop: MCP server support
- VS Code: via MCP extensions
Add Helius MCP Server
Install the Helius MCP server in your development environment:
This automatically configures your MCP client to access Helius documentation for AI assistance.
Start Using AI with Helius Context
Open your AI-powered IDE and start asking questions about Helius APIs. The AI will automatically query our MCP server for accurate, contextual documentation to help generate code.
Quick Test
Want to see it in action? Here’s the fastest way to test the Helius MCP integration:
- Open Cursor IDE
- Open a terminal and run:
npx mint-mcp add helius
- Open Agent mode (Ctrl/Cmd + K)
- Ask: “Write a Node.js script for sending transactions using Helius”
- The AI will reference our documentation via MCP to generate accurate code
- Watch as the AI generates working code using current Helius API patterns from our docs
- Open Cursor IDE
- Open a terminal and run:
npx mint-mcp add helius
- Open Agent mode (Ctrl/Cmd + K)
- Ask: “Write a Node.js script for sending transactions using Helius”
- The AI will reference our documentation via MCP to generate accurate code
- Watch as the AI generates working code using current Helius API patterns from our docs
- Open Windsurf IDE
- Run:
npx mint-mcp add helius
in terminal - Open the AI assistant
- Ask: “Show me how to get NFT data using Helius DAS API”
- The AI will reference our docs via MCP and generate code with proper imports and error handling
- Install Claude Desktop
- Run:
npx mint-mcp add helius
- Open Claude and ask: “Help me build a Solana transaction monitor with Helius”
- Get contextual responses with working code examples based on our documentation
Use Cases
Rapid Prototyping
Rapid Prototyping
Scenario: You need to quickly build a demo that fetches NFT data and displays it.
With MCP: Ask your AI tool “Create a React component that fetches and displays NFTs for a wallet using Helius DAS API”
Result: Get a complete component with proper error handling, loading states, and current API usage.
API Integration
API Integration
Scenario: Integrating Helius websockets into your application.
With MCP: “Show me how to set up Helius websockets for monitoring account changes”
Result: Complete websocket setup code with proper connection handling and real-time updates.
Documentation Generation
Documentation Generation
Scenario: Need to document your Helius integration for your team.

Best Practices
Be Specific
Ask specific questions like “How do I paginate through NFT results?” rather than “Help with NFTs”
Include Context
Mention your tech stack: “Using Next.js and TypeScript, show me how to…”
Iterate Quickly
Use the generated code as a starting point and ask for modifications
Test Generated Code

Troubleshooting
MCP Server Not Found
MCP Server Not Found
Issue: AI tool can’t find the Helius MCP server
Solution:
- Re-run
npx mint-mcp add helius
- Restart your AI tool
- Check that MCP is enabled in your tool’s settings
Outdated Information
Outdated Information
Issue: AI is providing outdated API information
Solution:
- The MCP server auto-updates, but you may need to refresh your AI session
- Clear your AI tool’s cache if available
- Ask specifically for “the latest” information
Generated Code Doesn't Work
Generated Code Doesn't Work
Issue: AI-generated code has errors or doesn’t run
