Use the CoinAPI Market Data API through a hosted MCP server with live metadata, quotes, trades, order books, OHLCV, exchange rates, and metrics tools.

Market Data API MCP

The CoinAPI Market Data API is available through a hosted Model Context Protocol (MCP) server. It exposes the API as self-describing tools that MCP-aware clients can inspect and call directly.

Why use MCP?

MCP puts JSON-Schema tool definitions in front of the underlying API so agent runtimes can:

discover available operations automatically
validate arguments before sending requests
reuse your normal X-CoinAPI-Key authentication
work with one hosted endpoint instead of a custom adapter

Server endpoint

https://mcp.md.coinapi.io/mcp

Use your regular CoinAPI API key in the X-CoinAPI-Key header.

Only the /mcp endpoint is supported for this service.

What is available through MCP?

The Market Data MCP server currently exposes 53 tools across these areas:

Area	What you can do
Metadata	Discover assets, exchanges, symbols, chains, mappings, and icon catalogs.
Exchange rates	Get spot conversion rates, one-to-many rates, historical rate series, and supported periods.
Quotes and trades	Fetch current quotes, recent quote updates, latest trades, and historical executions.
Order books	Access L2 snapshots, aggregated depth, recent book history, and L3 order-book views where supported.
OHLCV	Retrieve candle history, latest bars, exchange-wide bars, and valid period definitions.
Options	Inspect current options chains by exchange.
Metrics	Query both classic metrics and V2 external metrics for assets, exchanges, symbols, and chains.

Typical workflows

Market discovery

Call assets_list or exchanges_list.
Narrow down with symbols_list or symbols_get_by_exchange.
Use symbols_get_mapping when you need exchange-native symbol IDs.

Realtime market monitoring

Start from a known symbol_id such as BITSTAMP_SPOT_BTC_USD.
Call quotes_get_current_by_symbol for the live bid/ask snapshot.
Call trades_get_latest_by_symbol for recent executions.
Call orderbooks_get_current or orderbooks_get_depth for liquidity.

Historical analysis

Call ohlcv_list_periods or exchangerate_list_periods.
Use ohlcv_get_history, quotes_get_history, trades_get_history, or exchangerate_get_history.
Add metrics history tools when you need derived time series.

Live-tested notes

assets_list returns rich asset metadata including activity windows, volume, icon IDs, and chain addresses.
symbols_list can be filtered by exchange, asset, or symbol fragments to quickly locate valid symbol_id values.
quotes_get_current_by_symbol returns bid/ask plus nested last_trade data in one call.
ohlcv_get_history returns candles in ascending time order.
trades_get_latest_by_symbol returns the newest executions in descending order.
exchangerate_get_rate is also available here, so agents can combine symbol-level and asset-level pricing from one MCP server.
