Claude Code

Claude Code is Anthropic’s terminal-native coding agent. The integrations below are complementary — use any combination.

Setup

Install the SKILL

Gives Claude Code built-in knowledge of the CoinGecko API — writes correct requests without manual prompting.

npx skills add coingecko/skills -g -y

Full details: Agent SKILL

Add CoinGecko API MCP

Connects Claude Code to live CoinGecko data — prices, market caps, onchain pools, OHLCV, NFTs, and more.

claude mcp add --transport http \
  coingecko https://mcp.api.coingecko.com/mcp

claude mcp add --transport http \
  coingecko https://mcp.pro-api.coingecko.com/mcp

If using your API key, run /mcp inside a Claude Code session to authenticate:

Example Session

❯ /mcp

  Manage MCP servers
  1 server

  ❯ coingecko · △ needs authentication

  ↑↓ to navigate · Enter to confirm · Esc to cancel

Add Docs MCP

Lets Claude Code search CoinGecko documentation directly — endpoint references, guides, and tutorials.

Copy these prompts into your CLAUDE.md or paste at the start of a conversation to ensure Claude Code generates correct SDK code.

Prompt for integrating CoinGecko Python SDK

Once everything’s wired up, try asking Claude Code:

“Using the CoinGecko MCP, show me the top 10 trending pools on Base and export them to CSV.”
“What parameters does /coins/markets accept? Write a Python function that fetches the top 100 coins by market cap.”
“Write a TypeScript script that tracks my portfolio and alerts if any coin moves more than 10% in an hour.”
