Crypto Price & Market Analysis Server is a cryptocurrency data service that provides real-time price information, market analysis, and historical trends powered by the CoinCap API. Key features: - Real-time cryptocurrency price data for thousands of digital assets - Market analysis including market cap, trading volume, and price changes - Historical price trends and charting data - Support for both CoinCap API v2 and v3 - Dual transport support: STDIO for local clients and Streamable HTTP for remote connections - Optional API key configuration for higher rate limits

Crypto Price & Market Analysis MCP Server

A Model Context Protocol (MCP) server that provides comprehensive cryptocurrency analysis using the CoinCap API. This server offers real-time price data, market analysis, and historical trends through an easy-to-use interface. Supports both STDIO and Streamable HTTP transports.

What's New

Usage

Add this configuration to your Claude Desktop config file:

{
  "mcpServers": {
    "mcp-crypto-price": {
      "command": "npx",
      "args": ["-y", "mcp-crypto-price"]
    }
  }
}

If your MCP client requires launching via cmd.exe on Windows:

{
  "mcpServers": {
    "mcp-crypto-price": {
      "command": "cmd",
      "args": ["/c", "npx", "-y", "mcp-crypto-price"]
    }
  }
}

Run as Streamable HTTP server

You can run the server over HTTP for environments that support MCP over HTTP streaming.

npm run dev

# Build the HTTP bundle (outputs to .smithery/)
npm run build
Start the HTTP server
npm run start:http

# Build the STDIO bundle (outputs to dist/)
npm run build:stdio
Start the STDIO server
npm run start:stdio

The dev/build commands will print the server address to the console. Use that URL in clients that support MCP over HTTP (for example, Smithery). You can optionally provide an API key via COINCAP_API_KEY for higher rate limits.

Optional: CoinCap API Key

For higher rate limits, add an API key to your configuration:

{
  "mcpServers": {
    "mcp-crypto-price": {
      "command": "npx",
      "args": ["-y", "mcp-crypto-price"],
      "env": {
        "COINCAP_API_KEY": "YOUR_API_KEY_HERE"
      }
    }
  }
}

Note for Smithery CLI users

This MCP server works directly via npx (configs above) and does not require Smithery.

If you do use the Smithery CLI, authenticate with smithery auth login or by setting SMITHERY_API_KEY in your environment. Recent versions of the Smithery CLI do not support passing API keys via --key (or older --profile patterns).

> Important Note: CoinCap is sunsetting their v2 API. This MCP supports both v2 and v3 APIs: > - If you provide a COINCAP_API_KEY, it will attempt to use the v3 API first, falling back to v2 if necessary > - Without an API key, it will use the v2 API (which will eventually be discontinued) > - It's recommended to obtain an API key from pro.coincap.io/dashboard as the v2 API will be completely deactivated in the future

Verified commits & SSH signing

This repository requires Verified (cryptographically signed) commits. CI also includes a job (Verify commit signatures) that fails PRs with unsigned commits.

Create an SSH signing key (once)

# Generate a new ed25519 SSH key (no passphrase makes CI easier)
ssh-keygen -t ed25519 -C "CI signing key for mcp-crypto-price" -f ~/.ssh/id_ed25519 -N ''
Your keys will be at:
  Private: ~/.ssh/id_ed25519
  Public : ~/.ssh/id_ed25519.pub

Enable SSH signing locally (optional but recommended)

git config --global gpg.format ssh
git config --global user.signingkey ~/.ssh/id_ed25519.pub
git config --global commit.gpgsign true
Example signed commit
git commit -S -m 'feat: add something'

Configure GitHub to verify your signatures

1. Add your public key as an SSH Signing Key in your GitHub account: - GitHub → Settings → SSH and GPG keys → New SSH key - Key type: Signing Key (SSH) - Paste contents of ~/.ssh/id_ed25519.pub
