How to Use the Nansen (Blockchain Analytics) MCP in Cursor

Q: Can Cursor write trading scripts using live data from Nansen (Blockchain Analytics)?

Yes, your agent can call tools like smartmoneynetflow to fetch live token metrics and write functional scripts based on the active data. This eliminates the need for hardcoded mock data during development.

Build automated trading scripts and on-chain bots inside Cursor using real-time Nansen wallet and token metrics.

Perplexity

Inject real-time blockchain telemetry into your code

The `tgm_token_information` tool feeds live spot market metrics and token metadata directly into your active Cursor files. When you write execution logic, your agent pulls actual token data instead of placeholder values. This prevents integration bugs by letting you test your functions against live on-chain reality. You can immediately verify token performance by calling `tgm_token_ohlcv` for precise price and volume candles. Having this data inside your editor means you can build, debug, and test complex trading algorithms without constantly switching context to external browser tabs.

Build smart money alerts directly in Cursor

The `smart_money_dex_trades` tool streams the last 24 hours of decentralized exchange activity straight into your workspace. Your agent uses this live stream to generate precise TypeScript or Python structures for tracking whale wallets. It reads the incoming transaction arrays and writes corresponding event handlers on the spot. Combine this with `tgm_who_bought_sold` to build local scripts that track net accumulation trends. Because this MCP Server runs directly within Cursor's agent mode, the editor can generate backtesting templates using actual historical snapshots from `smart_money_historical_holdings`.

Profile smart contracts and counterparties as you code

The `profiler_premium_labels` tool identifies entity ownership and smart money designations for any address you highlight in your editor. If you are debugging a smart contract interaction, your agent can inspect the target's labels instantly. This prevents you from interacting with blacklisted or high-risk wallets during development. You can also extract interaction histories using `profiler_transactions` and map out behavioral clusters. This raw on-chain context helps you write better security checks, ensuring your dApp code accounts for actual transaction patterns observed via `profiler_counterparties`.

Setup guide

Set up Nansen (Blockchain Analytics) MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Nansen (Blockchain Analytics) MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Nansen (Blockchain Analytics) transactions." If the MCP tools are loaded correctly, Cursor will call the Nansen (Blockchain Analytics) tools automatically. You can also check Settings → MCP for a green status indicator.
