Documentation-backed NOWNodes context

What Is the NOWNodes MCP Server

A documentation-backed bridge between your AI assistant and blockchain APIs — built for developers who ship.

Code Generation

Generate ready-to-run curl, JavaScript, and Python calls built from real API definitions — not the model's best guess.

Supported Clients

Claude Desktop, Cursor, VS Code, Windsurf, and any other MCP-compatible client.

Blockchain Access

Direct access to 120+ blockchain netwoks like Solana, Ethereum and Bitcoin for AI agents.

Faster Development

Less time reading documentation, more time building blockchain apps with an assistant that actually knows the API.

How to get started

Go from a natural-language question to a production-ready blockchain API request without leaving your editor.

Connect the MCP server

Add the Model Context Protocol Server to your AI client.

Authenticate

Use your API key to authenticate generated requests and examples.

Ask in natural language

Search docs, explore methods, or generate blockchain API requests.

Build faster

Move from documentation lookup to implementation without leaving your workflow.

FAQ

What is an MCP server?

An MCP server is a program that gives an AI assistant a standard way to use real tools and data. It implements the Model Context Protocol (MCP) — an open standard for connecting large language models to external systems — and exposes capabilities the assistant can call.

How does an MCP server work?

An MCP-compatible client (Claude, Cursor, VS Code, and others) connects to the server and asks what it can do. The server describes its tools in plain language; when the assistant needs one, the client calls it, the server runs the action, and the result goes back to the model. Communication uses JSON-RPC, so one server works across every compatible client.

How is it different from calling the NOWNodes API directly?

Calling the API directly means you (or your AI assistant, guessing) still have to find the right method, format parameters, and get auth headers right. The MCP server hands your assistant documented methods, examples, and auth rules, so the request is correct the first time.

Which AI coding assistants does it work with?

Any MCP-compatible assistant, including Claude Desktop, Claude Code, Cursor, VS Code, and Windsurf.

Is the NOWNodes MCP Server free?

You connect it with a free NOWNodes API key, which the server uses in the requests it generates.

Which blockchains does it support today?

With the NOWNodes MCP Server, developers can access 120+ blockchain networks through AI coding assistants.

Does it require installation?

Yes. It runs as a local server: start it with Node and add it to your AI client's MCP config. Setup takes about a minute.

What can I build with it?

Anything that reads or writes blockchain data faster with AI help — wallets, explorers, trading tools, bots, AI agents, and backend services.
