market_data_metadataLABSCO SUMMARY
Rates and asset metadata straight from a Crypto APIs account.
Three tools cover the product: which assets exist, what one is worth in another, and the detail behind a single asset — reachable by symbol when that is what you have, and by asset ID when you need to be exact.
What it is
A Node MCP server over the Crypto APIs Market Data product. Three tools group the endpoints — metadata, exchange rates and asset details — each taking an action argument that selects the call.
What you get
- Supported crypto and fiat assets listed, with a type filter and pagination
- The exchange rate between two assets, by symbol or by asset ID
- Asset details fetched by asset ID or by symbol
Requirements
Node.js 18 or newer, and a Crypto APIs account with a key. The key goes in CRYPTOAPIS_API_KEY or on the command line. Runs over stdio through npx, or as HTTP on a port you choose, for clients such as n8n.
Setup effort
One command plus a key — npm install @cryptoapis-io/mcp-market-data, then supply credentials
USE CASES
01
Converting one asset into another
The exchange rate tool takes either symbols or asset IDs, so it works from whichever identifier you were handed.
02
Checking an asset is covered before you build on it
The list-supported-assets action returns crypto and fiat assets with a type filter and paging.
03
Resolving a ticker symbol to the asset behind it
Asset details come back from either the symbol or the asset ID, which settles ambiguous tickers.

}HTTP server for n8n
Start the server in HTTP mode. All Crypto APIs servers default to port 3000, so give each one its own --port if you run more than one:
HTTP SERVER FOR N8N · TERMINAL
npx @cryptoapis-io/mcp-market-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, using the port you started this server on.
