Claude Desktop

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS, %APPDATA%\Claude\claude_desktop_config.json on Windows):

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

Cursor

Add to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

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

MCP Inspector

npx @modelcontextprotocol/inspector npx @cryptoapis-io/mcp-transactions-data --api-key YOUR_API_KEY

n8n

Start the server in HTTP mode:

   npx @cryptoapis-io/mcp-transactions-data --transport http --port 3000 --api-key YOUR_API_KEY

In your n8n workflow, add an AI Agent node
Under Tools, add an MCP Client Tool and set the URL to http://localhost:3000/mcp

All servers default to port 3000. Use --port to assign different ports when running multiple servers.

`transactions_data_kaspa`

Kaspa transaction details (mainnet).

CLI Arguments

Argument	Description	Default
`--api-key`	Crypto APIs API key	`CRYPTOAPIS_API_KEY` env var
`--transport`	Transport type: `stdio` or `http`	`stdio`
`--host`	HTTP host	`0.0.0.0`
`--port`	HTTP port	`3000`
`--path`	HTTP path	`/mcp`
`--stateless`	Enable stateless HTTP mode	`false`

HTTP API Key Modes

When using HTTP transport, the server supports two API key modes:

With `--api-key`: The key is used for all requests. x-api-key request headers are ignored.
Without `--api-key`: Each request must include an x-api-key header with a valid Crypto APIs key. This enables hosting a public server where each user provides their own key.

# Per-request key mode (multi-tenant)
npx @cryptoapis-io/mcp-transactions-data --transport http --port 3000
# Clients send x-api-key header with each request

Stdio transport always requires an API key at startup.

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 any server.

Remote MCP Server

Crypto APIs provides an official remote MCP server with all tools available via HTTP Streamable transport at https://ai.cryptoapis.io/mcp. Pass your API key via the x-api-key header — no installation required.
