FAQs
Helius gives AI agents direct access to Solana via the fastest, most reliable infrastructure possible. Query wallet balances, parse and send transactions, monitor addresses via webhooks, stream real-time data, estimate priority fees—the options are endless. Agents can create a Helius account and configure an API key entirely on their own, with no browser needed.
Helius offers a suite of products that give AI the knowledge and live access it needs to build on Solana. The MCP Server includes 60+ tools that AI agents call directly against Solana. Structured inputs, structured outputs, no shell commands or parsing. It covers all available Helius products and includes autonomous account signup. Works with Claude Code, Cursor, Codex, and any MCP-compatible tool. Skills are instruction sets that make Claude a Solana specialist. Each skill routes your request to the right tools and reference files, follows correct SDK patterns, and avoids common mistakes. Available for general Solana development with Helius (Build), trading apps (via DFlow), frontend apps (via Phantom), and protocol internals (SVM). The Claude Code Plugin bundles the MCP server with expert skills. Install to get live Solana access with deeply informed coding guidance all in one step. The Helius CLI provides shell-level access to the same capabilities as the MCP server. Useful for CI/CD pipelines, scripting, and environments where MCP isn’t available. The TypeScript and Rust SDKs provide type-safe wrappers around Helius APIs for agents so they can call Helius directly from code, without going through an AI tool.
We recommend using the MCP for most use cases—it works with Claude Code, Cursor, Codex, and any MCP-compatible tool. Use the Claude Code plugin if you’re an avid Claude user and want skills bundled in with the MCP. Use the CLI for shell scripts and CI/CD pipelines where you need terminal-level automation. Use the TypeScript or Rust SDKs to write your own agent and have type-safe API access directly in code.
No. An AI agent can programmatically create a Helius account for you by generating a new Solana wallet. Send it 1 USDC and ~0.001 SOL, and the agent can call agenticSignup, which gives you an API key and 1,000,000 credits. Existing users can set their API key and use their plan to the fullest across any of our AI tools.
Getting started only costs 1 USDC, paid on-chain at signup, and includes 1,000,000 credits. Paid plans start at $49/month for higher rate limits and more credits. Sender, our transaction sending service, is included for free on all plans.
