MCP Data Redistribution Guidelines

At Nansen, our goal is to empower developers by providing access to the richest onchain data. We encourage you to build on top of our API and MCP, and these guidelines explain how to use and share Nansen’s data in your products while protecting the unique value of our insights.

All use of the Nansen API and MCP is subject to these guidelines and our official Terms of Service.

What do the statuses mean?

• ✅ Allowed: You may redistribute this data according to our terms.

• ✅ Allowed (with attribution): Allowed, but you must clearly display "Powered by Nansen API" or a backlink to Nansen.ai in your product.

• 🚫 Prohibited: Redistribution is NOT allowed.

• ⚠️ Restricted By-Default: Requires special approval. Contact Nansen for permission.

Attribution Requirements

If redistribution requires attribution:

• Add “Powered by Nansen API” clearly in your product.

• Or provide a visible link to Nansen.ai.

• Attribution is NOT required for personal or internal use.

General Rules

• All redistribution MUST follow Nansen’s Terms of Service.

• Always check the latest guideline update before product launches.

• These rules apply to both direct API responses and data derived from MCP.

• Do not provide bulk download features of Nansen responses or mirrored datasets.

• Do not create an API that proxies or wraps Nansen responses for third-party consumption.

• Do not share raw data with vendors or partners unless explicitly authorized.

Guide: Restricting MCP Tools

To ensure your application calls only approved MCP tools:

1. Load All Tools: Use MCP to load all available tools into your system.

2. Whitelist Selected Tools: Review the list and whitelist only the tools that meet your compliance or product needs. This means you will explicitly allow invocation of just these endpoints.

3. Export for LLMs: Share or export the whitelisted subset (rather than the full MCP set) directly to your LLM.

This workflow helps enforce governance and supports responsible integration with LLM-powered agents, without risking unauthorized data use.
