What is the Snowtrace (Avalanche Explorer) MCP Server?
Connect to the Snowtrace explorer and bring real-time Avalanche blockchain data into your AI workflows. Monitor addresses, analyze transactions, and audit smart contracts without leaving your conversation.
What you can do
- Account Analytics — Retrieve AVAX balances for single or multiple addresses (up to 20) in a single request.
- Transaction History — List normal and internal transactions for any wallet, including block ranges and sorting options.
- Token Tracking — Monitor ERC-20 and ERC-721 (NFT) transfer events to track asset movements across the network.
- Contract Inspection — Fetch verified source code and ABIs for smart contracts to understand protocol logic.
- Network Stats — Access block rewards, total AVAX supply, and the latest price data directly from the chain.
How it works
- Subscribe to this server
- Enter your Snowtrace API Key
- Start querying Avalanche data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Web3 Developers — quickly fetch contract ABIs and debug transaction execution status from your IDE.
- Data Analysts — aggregate wallet balances and token transfer history for on-chain research.
- Crypto Enthusiasts — monitor your portfolio and track NFT movements using natural language.

Why VS Code Copilot?
GitHub Copilot Agent mode brings Snowtrace (Avalanche Explorer) data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 21 tools. Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.
- —
VS Code is used by over 70% of developers. adding MCP tools to Copilot means your team can leverage external data without leaving their primary editor
- —
Project-scoped MCP configs (
.vscode/mcp.json) let you commit server configurations to your repository, ensuring the entire team shares the same tool access - —
Copilot's Agent mode integrates MCP tools seamlessly with file editing, terminal commands, and workspace search in a single agentic loop
- —
GitHub's enterprise compliance and audit features extend to MCP tool usage, providing visibility into how AI interacts with external services

Frequently asked questions
Can I check the balance of multiple Avalanche addresses at once?
Yes. Use the get_avax_balance_multi tool and provide a comma-separated list of up to 20 addresses to get all balances in a single response.
How do I track specific token movements like USDT or NFTs?
You can use get_erc20_transfers for standard tokens or get_erc721_transfers for NFTs. You can filter by wallet address or specific contract address to narrow down the results.
Is it possible to see the source code of a verified contract?
Absolutely. The get_contract_source_code tool retrieves the verified Solidity source code and metadata for any contract address that has been verified on Snowtrace.
Which VS Code version supports MCP?
MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.
How do I switch to Agent mode?
Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.
Can I restrict which MCP tools Copilot can access?
Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.
Does MCP work in VS Code Remote or Codespaces?
Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
MCP tools not available
Ensure you are in Agent mode in Copilot Chat. MCP tools only appear in Agent mode.
