Common questions
Is Coingecko MCP Server safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 5 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.
What can I use instead?

CoinGecko MCP Server
An MCP server for CoinGecko — connect any MCP-compatible client to free crypto market data.
What is this?
An MCP (Model Context Protocol) server that gives AI assistants and agents access to CoinGecko's free crypto market data API — prices, market caps, trending coins, historical data, and global stats — through natural language.
Use it with Claude Desktop, Cursor, Windsurf, Cline, Continue, or any MCP-compatible client to ask questions about crypto markets, compare tokens, and track prices.
Why use this?
- No API key required — CoinGecko's free tier works out of the box (rate-limited to ~27 calls/min)
- 8 built-in tools — covers the most common crypto data queries
- Clean markdown output — results read naturally in chat
- Rate-limited automatically — respects free tier limits, retries on 429
Tools
| Tool | Description |
|---|---|
search_coins | Search for cryptocurrencies by name or symbol |
get_prices | Get current prices, market caps, and 24h changes for one or more coins |
get_market_overview | Get top N coins by market cap with full stats |
get_trending | Get currently trending coins (last 24h search volume) |
get_coin_details | Get detailed info about a specific coin (description, links, market data, categories) |
get_price_history | Get historical price data (daily, weekly, monthly, yearly) |
get_global_stats | Get global crypto market stats (total MCap, BTC dominance, active cryptos) |
get_token_price_comparison | Compare prices and stats of multiple tokens side-by-side |
Quick Start
1. Add to your MCP client
Add this to your MCP client config (e.g. claude_desktop_config.json):
{"mcpServers": { "coingecko": { "command": "npx", "args": ["-y", "coingecko-mcp-server"] } } }
That's it. No API key, no install step. npx downloads and runs it automatically.
2. Use it
Ask your AI assistant things like:
- "What's the current price of Bitcoin and Ethereum?"
- "Show me the top 10 coins by market cap"
- "What's trending on CoinGecko right now?"
- "Compare Solana, Avalanche, and Polkadot"
- "How has Bitcoin performed over the last 30 days?"
- "What's the total crypto market cap and BTC dominance?"
- "Search for AI-related crypto tokens"
- "Tell me about Chainlink — categories, links, market data"
Example Output
get_trending
🔥 Trending Coins (last 24h):- Bitcoin (BTC) — Rank #1 | MCap: $1,340.2B | 24h: +2.1%
- Ethereum (ETH) — Rank #2 | MCap: $412.8B | 24h: +1.8%
- Solana (SOL) — Rank #5 | MCap: $78.4B | 24h: +4.3%
...
get_token_price_comparison
Token Comparison (USD):| Coin | Price | MCap | 24h | 7d | Vol |
|---|---|---|---|---|---|
| Bitcoin (BTC) | $67,234 | $1,340.2B | +2.1% | +5.3% | $28,400M |
| Ethereum (ETH) | $3,456 | $412.8B | +1.8% | +3.1% | $14,200M |
| Solana (SOL) | $178.5 | $78.4B | +4.3% | +12.1% | $3,800M |
Use Cases
Portfolio Research
Ask "What's my portfolio worth?" after listing your holdings. The server compares prices across multiple tokens and gives you a snapshot with market caps, 24h changes, and volume.
Yield Farming Research
"Show me trending coins with high volume" — find new opportunities by checking what's getting attention. Combine with get_coin_details to deep-dive into categories and links before committing.
Market Intelligence
"What's the total crypto market cap and BTC dominance?" gives you macro context in seconds. Use get_global_stats before making any allocation decision.
Token Comparison
"Compare Solana, Avalanche, and Polkadot" — side-by-side price, market cap, and performance data. Faster than opening three tabs on CoinGecko.
Historical Analysis
"How has Bitcoin performed over the last 30 days?" — daily price history for trend analysis. Works with any timeframe (daily, weekly, monthly, yearly).
Security
- No API key by default — uses CoinGecko's free tier. Optional API key for higher rate limits.
- Read-only — only fetches public market data from CoinGecko's API. No writes, no mutations.
- No local file access — does not read or write any files on your machine.
- No shell access — does not execute commands or spawn processes.
- Rate-limited — automatically caps requests to stay within free tier limits.
- Open source — MIT licensed. Inspect the code at GitHub.
Troubleshooting
Rate limit errors (429)
The server auto-retries on 429, but if you're making rapid queries, add a short delay between requests. Free tier allows ~27 calls/minute. If you hit this frequently, set a COINGECKO_API_KEY for higher limits.
"Coin not found" errors
Use search_coins first to find the correct CoinGecko ID. Coin IDs are lowercase slugs (e.g. bitcoin, ethereum, solana), not ticker symbols.
Server won't start
Make sure Node.js 18+ is installed: node --version. If using npx, ensure npm is up to date: npm install -g npm@latest.
MCP client can't connect
Verify the config path is correct. Claude Desktop uses ~/Library/Application Support/Claude/claude_desktop_config.json on macOS and %APPDATA%\Claude\claude_desktop_config.json on Windows. Restart the client after config changes.
Slow responses
CoinGecko's free tier has ~300ms latency per call. Multi-coin queries (get_prices, get_token_price_comparison) make one API call regardless of how many coins you pass, so batch your queries.
Requirements
- Node.js 18+
- No API key needed (CoinGecko free tier)
Rate Limits
The server automatically rate-limits requests to ~27 calls/minute to stay within CoinGecko's free tier. If you have a CoinGecko Pro API key, you can set the COINGECKO_API_KEY environment variable for higher limits:
{"mcpServers": { "coingecko": { "command": "coingecko-mcp-server", "env": { "COINGECKO_API_KEY": "your_key_here" } } } }
Development
