Notion AI Agents support custom MCP connections, giving your agent access to live CoinGecko data — prices, market trends, onchain analytics, and more.
Notion requires authenticated MCP — CoinGecko API key is needed.

​
Setup

1

Create an AI agent

Open Notion and navigate to AI Agents (or click + New agent from the sidebar). Describe what your agent should do.
2

Add MCP connection

In your agent’s settings, click Add connection. Scroll to the bottom of the left sidebar and click + Add custom MCP.
3

Configure the MCP server

Fill in the connection form:
FieldValue
MCP server URLhttps://mcp.pro-api.coingecko.com/mcp
NameCoinGecko MCP
AuthenticationOAuth
Notion displays a warning: “Notion hasn’t reviewed this server.” This is expected for all custom MCP servers.
Click Connect.
4

Authorize with your API key

A browser tab opens at mcp.pro-api.coingecko.com/authorize. Paste your API key and click Log in and Approve.
Get a key at coingecko.com/en/api/pricing.

​
Try It Out

Your Notion AI agent now has access to live CoinGecko data. Try these prompts:
  • “What is the current price of Bitcoin in USD?”
  • “Show me the top 10 cryptocurrencies by market cap with price, 24h change, and volume in a table.”
  • “What are the top trending coins on CoinGecko right now?”
  • “Research the top 5 DeFi coins and save a summary to this page.”
  • “Pull today’s trending coins and add them as a database entry.”

​
Troubleshooting

Make sure the MCP server URL begins with https:// and is a complete, valid URL.
This appears for all custom MCP connections and is not an error. Safe to proceed.
Check that your browser isn’t blocking popups from Notion. Allow popups and retry.
Confirm the MCP connection is active in your agent’s settings. Re-authorize if your session has expired.
