Why This Server Exists

Most agent tasks need a quick high-level market snapshot before deeper exchange or derivatives analysis. This server provides that common layer with:

  • public market data sources

  • simple MCP tool contracts

  • bounded input handling

  • optional news support without requiring it for the rest of the server

Requirements

  • Python 3.11+

  • No API key is required for the core tools

  • Optional keys improve rate limits or enable news

Quick Start

  1. Create your local env file:

cp secrets/market_data.env.example secrets/market_data.env

  1. Optionally set:

  • COINGECKO_API_KEY

  • CRYPTOPANIC_API_KEY

  1. Run locally:

pip install -e .
python -m market_data_mcp

Docker

docker build -t market-data-mcp .
docker run --rm -p 38089:38089 --env-file secrets/market_data.env market-data-mcp

Development

Install test dependencies and run tests:

pip install -e ".[test]"
pytest

Security Notes

  • Do not commit secrets/market_data.env

  • If you expose HTTP externally, put it behind your own auth or trusted network boundary

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd

    Your agent needs crypto prices it can rely on — spot, ranked market tables, history, OHLC, per-venue tickers, and what is trending right now. **What you can ask for** • "What is the price of these 20 tokens in USD and EUR right now?" • "Give me the top 100 by market cap with 24h and 7d change." • "Chart this coin's price over the last year, hourly." • "Where does this token trade, and at what spread per venue?" • "What is trending on CoinGecko today?" **How to use it** Point any MCP client at https://mcp.aisa.one/crypto-market-data/mcp and sign in with OAuth — there is no key to create or paste. 21 CoinGecko tools: simple price and token price by contract, supported currencies, coin list and detail, ranked markets, history, market charts and ranges, OHLC, per-coin tickers, categories, exchanges and their tickers, token data and charts, and trending. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Price the token here, then ask the same agent what X is posting about it — without adding a second server. **What it costs** Finding and inspecting an operation is free. Running one is billed per call at API prices, with no seat and no monthly minimum, and every call takes max_price_usd so an agent cannot overspend by accident. **Where else it reaches** https://mcp.aisa.one/finance/mcp for equities, crypto and prediction markets in one place.
