Initial release — CoinGecko market-data MCP server

Cryptocurrency market data via the live CoinGecko v3 REST API. Read-only, keyless by default; optional COINGECKO_API_KEY attaches the Demo-tier header.

Added:

  • 8 tools: coingecko_search_coins, coingecko_get_prices, coingecko_list_markets, coingecko_get_coin, coingecko_get_market_chart, coingecko_get_trending, coingecko_get_global, coingecko_list_categories
  • 2 resources: coingecko://coin/{id}, coingecko://global
  • coingecko_coin_research prompt — guides the search → get_coin → get_market_chart → get_global chain
  • COINGECKO_API_KEY optional env var (x-cg-demo-api-key header); keyless public tier by default
  • CoinGecko service — one method per endpoint, fetch+parse wrapped in withRetry (429/5xx/timeout); 404 surfaces as typed coin_not_found. Every output carries CoinGecko attribution.

44 tests pass; bun run devcheck clean.
