Check Crypto Prices and Market Mood Through CoinMarketCap

Through an AnythingMCP custom connector, your muse can answer crypto questions in plain words with current market numbers: what a coin costs now, which coins moved most, and how the market feels today.

What it does

The connector adds 22 tools, and every one only reads. The muse can give you a coin's current price in your currency, with market size, volume, and changes from the last hour to 90 days. It can list the top coins by market size, pull past prices at set intervals, open a coin's profile with its description and tags, and list coins in a category such as DeFi or AI. For the wider picture, it reports total market size, how much of it Bitcoin and Ethereum make up, and two mood gauges scored from 0 to 100: a Fear and Greed index, and an Altcoin Season index, where above 75 points to altcoin season and below 25 to Bitcoin season. It can convert amounts between currencies and read an exchange's proof-of-reserves wallets.

How to use it

1. Start an AnythingMCP account and add the CoinMarketCap connector.
2. Sign up for a CoinMarketCap API key. The free Basic plan covers most tools.
3. Copy the API key from your dashboard into the connector. Enter it only there, never in a chat.
4. In Muse, open Settings, then Connectors, and add a custom connector with the MCP server address AnythingMCP gives you. Sign in and approve.
5. Ask a plain question, such as what three coins are worth and how they moved today.
6. When a ticker could mean more than one coin, check the full name in the answer. Tickers are not unique.

What you need

• A Muse account that can add custom connectors
• An AnythingMCP account with the CoinMarketCap connector added
• A CoinMarketCap API key, free on the Basic plan

What to watch for

• The connector only reads market data. It cannot trade, see wallets or exchange accounts you own, or set price alerts.
• Every call spends plan credits. The free Basic plan gives 10,000 credits a month and 30 requests a minute, enough for daily checks.
• A few tools need a paid plan, including the gainers and losers list. On the free plan, past prices reach one month back at fine intervals and one year back by day.
• Prices move fast. Check the time on a figure before you act on it.
• This is a custom connector, and Meta does not review custom connectors. You can disconnect it in Settings at any time. The muse prepares, you decide.
