How to Use the Helius (Solana) MCP in VS Code Copilot

Q: How do I share the Helius (Solana) integration with my VS Code Copilot team?

Add the server configuration to your project's .vscode/mcp.json file and push it to Git. Anyone who pulls the repo and has Copilot Agent mode enabled will automatically inherit the tools.

Q: Can VS Code Copilot read Helius (Solana) token balances?

Yes, the getwalletbalances endpoint returns both token amounts and their current USD valuations. You can use this to quickly verify testnet or mainnet account states without leaving your editor.

Q: Does the MCP Server support fetching compressed assets in VS Code Copilot?

The getassetproof tool is built specifically for this. It returns the Merkle tree data you need to validate compressed NFTs within your local environment.

Shared Helius (Solana) MCP Server Config

`get_asset_batch` fetches multiple token metadata objects in a single network request. Your entire team gets access to this tool the moment you commit the `.vscode/mcp.json` file to your repository. Junior developers no longer need to write custom curl scripts to test RPC endpoints. They simply ask their AI client to pull the metadata for a list of mints, and it returns the structured JSON directly in their IDE.

Audit Smart Contract Interactions

`get_transaction_history` pulls the complete execution record for any program ID on the network. You ask Copilot to review a specific contract, and it grabs the latest invocations to check for failed instructions. It then feeds those signatures into `parse_transactions` to decode the arguments. The agent reads the human-readable output and highlights which specific instructions are causing the transaction to revert.

Resolve On-Chain Identities

`get_wallet_identity` translates raw base58 addresses into registered .sol domains. When you review a hardcoded list of admin wallets in your configuration files, the agent can verify who actually owns them. You can also trace where those admin wallets originated using `get_wallet_funded_by`. Copilot checks the initial funding transaction to ensure the deployment accounts were seeded by authorized company addresses.

Setup guide

Set up Helius (Solana) MCP in VS Code Copilot

Prerequisites

VS Code 1.99 or later with GitHub Copilot extension
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.
2

Add the Helius (Solana) MCP

Paste the JSON snippet shown on the right into your .vscode/mcp.json. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Switch to Agent mode

Open Copilot Chat (Cmd+Shift+I / Ctrl+Shift+I) and switch to Agent mode using the dropdown. MCP tools are only available in Agent mode — they do not appear in Edit or Ask modes.
4

Verify the connection

In the Copilot Chat input, type # to list available tools. You should see the Helius (Solana) tools listed. Try asking: "List my recent Helius (Solana) transactions" and Copilot will invoke them automatically.

Each developer's Copilot instance executes the tools locally via their own machine. If you share a single API key, you will hit the rate limits faster, so assign individual keys via local environment variables.

Enterprise teams rely on Vinkius's zero-trust architecture. Your proprietary smart contract transaction histories and parsed instruction logs are processed ephemerally and never stored on persistent storage volumes.
