Quickstart

Make your first API call

Create your free Helius account

Send your first request

Open the Get started tab in your dashboard, select getBalance method and click Send request.

Helius dashboard Get started section: click Send request

Success!

You just queried getBalance method to get the balance of the wallet address. You should see a response like this:

{
  "jsonrpc": "2.0",
  "result": {
    "context": {
      "slot": 434696579,
      "apiVersion": "3.1.9"
    },
    "value": 1266028802962
  },
  "id": 1
}

Try other methods like getTransactionsForAddress to get the transaction history or getAccountInfo to get the account details.

Next steps

You have data flowing. Pick your next move.

Connect your AI coding tool

Add the Helius MCP server so your AI assistant builds and debugs with live Solana data.

Send your first transaction

Land a transaction on-chain with priority fees and direct routing to leaders.

Stream live data

Subscribe to real-time on-chain updates over gRPC or enhanced WebSockets.

Build your first app

Follow a self-contained track with copy-pasteable code you can run in minutes.

Connect your AI coding tool

Connect the Helius MCP server to your AI tool so it can build and debug with live Solana data (balances, asset metadata, parsed transactions, webhooks, and streaming) instead of guessing. Works with Claude Code, Claude Desktop, Cursor, VS Code, Windsurf, Codex, and any MCP-compatible tool.

Run the following command:

claude mcp add helius npx helius-mcp@latest

Or add to your project’s .mcp.json:

{
  "mcpServers": {
    "helius": {
      "command": "npx",
      "args": ["helius-mcp@latest"]
    }
  }
}

Verify with:

claude mcp list

Want skills + MCP in one step? Install the Helius plugin instead:

claude plugin install helius @claude-plugins-official

Open Settings > Developer > Edit Config and add the server:

{
  "mcpServers": {
    "helius": {
      "command": "npx",
      "args": ["helius-mcp@latest"]
    }
  }
}

Restart Claude Desktop to apply.

Open the command palette (Cmd/Ctrl + Shift + P), search for MCP: Add Server, and enter:

Name: helius
Command: npx helius-mcp@latest

Or add to your project’s .cursor/mcp.json:

{
  "mcpServers": {
    "helius": {
      "command": "npx",
      "args": ["helius-mcp@latest"]
    }
  }
}

Create a .vscode/mcp.json file in your project root:

{
  "servers": {
    "helius": {
      "command": "npx",
      "args": ["helius-mcp@latest"]
    }
  }
}

Requires the GitHub Copilot extension with MCP support enabled.

Open the command palette (Cmd/Ctrl + Shift + P), search for Configure MCP Servers, and add:

{
  "mcpServers": {
    "helius": {
      "command": "npx",
      "args": ["helius-mcp@latest"]
    }
  }
}

Run the following command:

codex mcp add helius -- npx helius-mcp@latest

Or add to your ~/.codex/config.toml (or .codex/config.toml for project-scoped):

[mcp_servers.helius]
command = "npx"
args = ["helius-mcp@latest"]

Verify with:

codex mcp list
