Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Or run it on your computer

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "cryptoapis-io": {
      "command": "npx",
      "args": [
        "-y",
        "@cryptoapis-io/mcp"
      ],
      "env": {
        "CRYPTOAPIS_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add --transport http cryptoapis-io https://ai.cryptoapis.io/mcp --header 'x-api-key: your-value'

Or run it on your computer

claude mcp add cryptoapis-io --env CRYPTOAPIS_API_KEY=your-value -- npx -y @cryptoapis-io/mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "cryptoapis-io": {
      "url": "https://ai.cryptoapis.io/mcp",
      "headers": {
        "x-api-key": "your-value"
      }
    }
  }
}

Or run it on your computer

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

      ],
      "env": {
        "CRYPTOAPIS_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "cryptoapis-io": {
      "type": "http",
      "url": "https://ai.cryptoapis.io/mcp",
      "headers": {
        "x-api-key": "your-value"

Common questions

Is CryptoAPIs Io MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: CRYPTOAPIS_API_KEY, x-api-key

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.5.0) reached the registry 17 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Master CSS

@cryptoapis-io/mcp

The combined Crypto APIs MCP server — all 14 data products in a single process, one command.

What's Included

Every tool is named __ (e.g. block_data__evm_block_data):

Product	Tools
`address_history`	Manage synced addresses, full tx/token history (EVM, UTXO)
`address_latest`	Current balance/state (EVM, UTXO, Solana, XRP, Kaspa)
`aml`	AML address verification and transaction screening
`block_data`	Block-level data (EVM, UTXO, XRP)
`blockchain_events`	Webhook subscriptions — create and manage
`blockchain_fees`	Fee recommendations and gas estimation (EVM, UTXO, XRP, Tezos, Solana)
`broadcast`	Broadcast signed raw transactions
`contracts`	Smart contract ABIs and on-chain data (EVM, Solana)
`hd_wallet`	xpub/HD wallet balance and sync (EVM, UTXO, XRP)
`market_data`	Asset prices, exchange rates, metadata
`prepare_transactions`	Build unsigned transactions (EVM, Tezos, Solana, Kaspa, XRP, UTXO, Tron)
`simulate`	Dry-run Ethereum transaction simulation
`transactions_data`	Transaction lookup and listing
`utils`	Address derivation and encoding utilities

Each product also registers its prompts and a cryptoapis:// /... resource.

Not included: @cryptoapis-io/mcp-signer (local transaction signing), @cryptoapis-io/mcp-x402-pay (buyer-side x402), and @cryptoapis-io/mcp-x402-accept (merchant-side x402 paywall) are separate installs — they move money or hold keys, which this combined server deliberately does not.

Prerequisites

Node.js 18+
Crypto APIs account and API key (sign up | get API key)

Usage

npx @cryptoapis-io/mcp --api-key YOUR_API_KEY

Or via environment variable:

export CRYPTOAPIS_API_KEY=YOUR_API_KEY

npx @cryptoapis-io/mcp

Claude Desktop

"mcpServers": { "cryptoapis": { "command": "npx", "args": ["-y", "@cryptoapis-io/mcp"], "env": { "CRYPTOAPIS_API_KEY": "your_api_key_here" } } } }

Cursor

Add to .cursor/mcp.json:

"mcpServers": { "cryptoapis": { "command": "npx", "args": ["-y", "@cryptoapis-io/mcp"], "env": { "CRYPTOAPIS_API_KEY": "your_api_key_here" } } } }

VS Code

Add to .vscode/mcp.json:

"servers": { "cryptoapis": { "command": "npx", "args": ["-y", "@cryptoapis-io/mcp"], "env": { "CRYPTOAPIS_API_KEY": "your_api_key_here" } } } }

Remote MCP Server

Crypto APIs also hosts this same combined server over HTTP Streamable transport at https://ai.cryptoapis.io/mcp — no installation required. Pass your API key via the x-api-key header with each request:

"mcpServers": { "cryptoapis": { "url": "https://ai.cryptoapis.io/mcp", "headers": { "x-api-key": "your_api_key_here" } } } }

HTTP Transport (self-hosted)

npx @cryptoapis-io/mcp --transport http --api-key YOUR_API_KEY

See the main README for the full list of CLI arguments, HTTP API key modes, and exposing the server beyond localhost.

Only need a few products?

Install just the packages you use instead of the combined server:

npx @cryptoapis-io/mcp-block-data --api-key YOUR_API_KEY

See docs for the full API reference.

Important: API Key Required

Warning: Making requests without a valid API key — or with an incorrect one — may result in your IP being banned from the Crypto APIs ecosystem. Always ensure a valid API key is configured before starting the server.
