Perplexity

Standardize on-chain data access across your team

The `tgm_flow_intelligence` tool segments token flows into exchange, whale, and smart money categories directly within your VS Code Copilot panel. By committing a configuration file to your repository, every developer on your team instantly gains access to the same live blockchain metrics. This ensures everyone builds features using identical, verified datasets. Your team can use `tgm_flows` to track hourly movement trends across various token categories. Having these tools integrated directly into VS Code Copilot removes the friction of managing individual API keys, as Vinkius handles the underlying authentication for the entire workspace.

Query this MCP Server for instant wallet audits

The `profiler_transactions` tool retrieves recent blockchain transactions for any address directly inside your editor. When reviewing code or auditing smart contracts, your team can instantly query the on-chain behavior of target wallets. This allows you to verify contract interactions without leaving your active workspace. Combine this transaction data with `profiler_related_wallets` to automatically map out connected addresses. Copilot reads these relationships and helps your developers write robust validation rules that flag suspicious or high-risk counterparties before code is pushed to production.

Analyze DeFi positions and token indicators on the fly

The `portfolio_defi_holdings` tool tracks active DeFi positions across multiple protocols for any target address. Your developers can use this tool to inspect yield farming balances, debt ratios, and liquidity pool exposures. This raw data helps you build accurate portfolio tracking features without relying on slow, manual API testing. You can also fetch risk and reward scores for specific tokens using `tgm_indicators`. This allows your team to build real-time risk assessment modules, leveraging Nansen's proprietary scoring metrics directly inside your development environment.

Setup guide

Set up Nansen (Blockchain Analytics) 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 Nansen (Blockchain Analytics) 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 Nansen (Blockchain Analytics) tools listed. Try asking: "List my recent Nansen (Blockchain Analytics) transactions" and Copilot will invoke them automatically.

.vscode/mcp.json

{
  "mcpServers": {
    "nansen-blockchain-analytics-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
