market-data-mcp
market-data-mcp is an MCP server that combines broad crypto market data from CoinGecko, the Crypto Fear & Greed Index, and optional CryptoPanic news into one tool surface for agents.
What It Covers
Global market overview
Fear & Greed index with history
Top coins by market cap
Detailed coin lookups by CoinGecko ID
Search for CoinGecko IDs
Trending assets
Optional news feed from CryptoPanic
Why This Server Exists
Most agent tasks need a quick high-level market snapshot before deeper exchange or derivatives analysis. This server provides that common layer with:
public market data sources
simple MCP tool contracts
bounded input handling
optional news support without requiring it for the rest of the server
Requirements
Python 3.11+
No API key is required for the core tools
Optional keys improve rate limits or enable news
