Research → Summarize → Create document → Send notification
Complete complex tasks end-to-end without manual steps
Share your MCP server with the developer community
crypto-data-mcp has been reliable for tool-calling workflows; the MCP profile page is a good permalink for internal docs.
We wired crypto-data-mcp into a staging workspace; the listing’s GitHub and npm pointers saved time versus hunting across READMEs.
crypto-data-mcp is a well-scoped MCP server in the explainx.ai directory — install snippets and categories matched our Claude Code setup.

crypto-data-mcp is among the better-indexed MCP projects we tried; the explainx.ai summary tracks the official description.
According to our notes, crypto-data-mcp benefits from clear Model Context Protocol framing — fewer ambiguous “AI plugin” claims.
I recommend crypto-data-mcp for teams standardizing on MCP; the explainx.ai page compares cleanly with sibling servers.

Real-time cryptocurrency data for AI coding tools. An MCP server that gives Claude Code, Cursor, and other MCP-compatible tools access to live prices, market data, token info, and historical charts -- powered by CoinGecko.
Built by Whoff Agents.
# Clone the repo
git clone https://github.com/whoff-agents/crypto-data-mcp.git
cd crypto-data-mcp
# Install with uv (recommended)
uv sync
# Or install with pip
pip install -e .
pip install crypto-data-mcp
Add to your Claude Code MCP config at ~/.claude/claude_desktop_config.json:
{
"mcpServers": {
"crypto-data": {
"command": "uv",
"args": [
"--directory", "/path/to/crypto-data-mcp",
"run", "crypto-data-mcp"
]
}
}
}
Or if installed globally via pip:
{
"mcpServers": {
"crypto-data": {
"command": "crypto-data-mcp"
}
}
}
Then in Claude Code, you can ask things like:
get_priceGet the current price for a single token.
Parameters:
| Param | Type | Default | Description |
|---|---|---|---|
symbol | string | required | Token symbol (BTC, ETH, SOL) or CoinGecko ID |
currency | string | "usd" | Quote currency (usd, eur, gbp, etc.) |
Example response:
{
"symbol": "BTC",
"coingecko_id": "bitcoin",
"currency": "usd",
"price": 67250.00,
"price_change_24h_pct": -1.82,
"market_cap": 1325000000000,
"volume_24h": 28500000000,
"last_updated_at": 1712000000
}
get_pricesGet prices for multiple tokens in one call. More efficient than calling get_price repeatedly.
Parameters:
| Param | Type | Default | Description |
|---|---|---|---|
symbols | list[string] | required | List of symbols (max 50) |
currency | string | "usd" | Quote currency |
Example response:

The server includes a built-in mapping for 70+ popular tokens (BTC, ETH, SOL, USDT, USDC, BNB, XRP, ADA, DOGE, AVAX, and many more). For tokens not in the built-in map, it automatically searches CoinGecko to resolve the symbol.
All data comes from the CoinGecko API (free tier). The server includes:
The free CoinGecko tier allows approximately 10-30 requests per minute.
# Install dependencies
uv sync
# Run tests (uses live CoinGecko API -- may hit rate limits)
uv run pytest tests/ -v
# Run the server directly

💡 Pro Tips
Architecture
Model Context Protocol standardizes how AI hosts (Claude, Cursor) communicate with external tools and data sources through server implementations.
Protocols
Compatibility
✓ Use when
Use when you need Claude to access external data, execute actions, or integrate with tools. Best for extending AI capabilities beyond conversation.
✗ Avoid when
Avoid when native integrations exist (use official APIs directly), for real-time critical systems, or when security/compliance requires zero external dependencies.
