Simsar

Everything your AI needs to read the crypto market.

Prices, indicators, sentiment, news — one MCP server, zero config.

No signup. No API keys. No tracking.

The problem

Claude and ChatGPT are blind to live markets. Ask them Bitcoin's price — they'll guess, apologize, or give you yesterday's data.

You could write Python scripts, wrestle with exchange APIs, handle auth and rate limits... or you could just install Simsar.

What Simsar gives your AI

Real-time prices

All 2000+ Binance trading pairs. OHLCV candles from 1m to 1w.

39 technical indicators

RSI, MACD, EMA, SMA, Bollinger Bands, ATR, Stochastic, and more.

Market sentiment

Fear & Greed Index, funding rates, open interest, long/short ratios.

News & economic calendar

Crypto news, forex updates, FOMC dates, CPI releases.

Quick start

1. Install

claude mcp add simsar -- uvx --from git+https://github.com/miratcan/simsar-mcp simsar-mcp

2. Ask your AI

"What's Bitcoin's price and RSI on 4h?"

"Is the market fearful or greedy right now?"

"Compare BTC and ETH momentum."

"When is the next FOMC meeting?"

"Show me SOL's Bollinger Bands."

That's it. Your AI can now see the market.

Why I built this

I got tired of writing the same data-fetching code every time I wanted my AI to analyze a chart. So I packaged it into an MCP server and made it public.
