How to Use the Nansen (Blockchain Analytics) MCP in Claude Code

Q: How do I use the Nansen (Blockchain Analytics) server in a shell script with Claude Code?

You use the claude mcp call command. For example, claude mcp call nansen-blockchain-analytics-mcp tgmflows --params '{"tokenaddress":"0x..."}' will return raw JSON, which you can then pipe to tools like jq for processing.

Q: How would I monitor for new smart money activity with Nansen (Blockchain Analytics) and Claude Code?

Create a script that polls the smartmoneydextrades tool. You can filter for large transactions and cross-reference the wallet with profilerpremiumlabels to see if it's a known fund or whale.

Q: Is it possible to get historical data for backtesting?

Yes. The server includes tools like profilerhistoricalbalances and tgmtokenohlcv which provide historical snapshots and price data. You can script Claude Code to pull years of data for analysis.

Pipe Nansen's institutional-grade blockchain data directly into your shell scripts and CI/CD pipelines using Claude Code.

Perplexity

On-Chain Data for Your Terminal

This isn't for dashboards; it's for automation. Use Claude Code to query any of the 48 Nansen tools and pipe the raw JSON output to `jq`, `awk`, or another script. It's designed for headless execution in your CI/CD pipelines or cron jobs. For example, set up a cron job to check `smart_money_netflow` for a token every five minutes. If inflows exceed a threshold, pipe the alert to a shell script that sends a notification. It's as simple as `claude mcp call nansen-blockchain-analytics-mcp smart_money_netflow ... | jq`.

Headless Wallet Intelligence

Run deep wallet investigations without ever leaving your terminal. Chain commands together in a shell script to build a complete picture. Start by getting an address's top counterparties with `profiler_counterparties`, then check their PnL with `profiler_pnl_summary`. This MCP Server lets you build powerful, repeatable workflows. Create a script that takes a wallet address as an argument, then calls `profiler_labels`, `profiler_related_wallets`, and `portfolio_defi_holdings` to generate a full text-based report. It's analysis as code.

Your MCP Server for Data Pipelines

Use Claude Code as a bridge between Nansen's API and your own backend services. Fetch real-time DEX trades with `tgm_dex_trades` and ingest them into a time-series database. The output is clean JSON, ready for processing. You can build sophisticated data pipelines this way. Set up a job in a Docker container that uses `tgm_who_bought_sold` to track buy/sell pressure, then writes the aggregated data to a message queue for other services to consume. Claude Code is the glue.
