Most list endpoints use cursor-based pagination:
// Response
{
"items": [...],
"limit": 10,
"hasMore": true,
"nextStartingAfter": "abc123"
}
Use nextStartingAfter value as startingAfter parameter in the next request.
Exception: list-unconfirmed-transactions (UTXO) uses offset pagination with limit, offset, and total fields.
For stdio transport, provide the API key at startup via CLI argument or environment variable. For HTTP transport, it can also be provided per-request via x-api-key header (see HTTP API Key Modes).
Command-line argument (recommended):
npx @cryptoapis-io/mcp-address-latest --api-key {your_api_key}
Environment variable:
export CRYPTOAPIS_API_KEY={your_api_key}
| Argument | Description |
|---|---|
--api-key | Crypto APIs API key |
--transport | Transport type: stdio (default) or http |
--host | HTTP host (default: 0.0.0.0) |
--port | HTTP port (default: 3000) |
--path | HTTP path (default: /mcp) |
--stateless | Enable stateless mode for HTTP |
When using HTTP transport, the server supports two API key modes:
--api-key: The key is used for all requests. x-api-key request headers are ignored.--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-address-latest --transport http --port 3000
# Clients send x-api-key header with each request
Stdio transport always requires an API key at startup.
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.
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.
