Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

CryptoQuant MCP stdio proxy - connects MCP clients to the remote CryptoQuant MCP server

Readme

CryptoQuant MCP

npm version License: MIT

CryptoQuant on-chain, market, and derivatives data, plus CryptoQuant Research and QuickTake insights, for AI agents through the Model Context Protocol.

This repository contains:

  • Remote server setup for https://mcp.cryptoquant.com/mcp (recommended; you sign in with OAuth)
  • An Agent Plugins / Cursor plugin (plugin.json, mcp.json, skills/) that connects to the remote server and teaches the agent which metric answers which question
  • A local stdio proxy (npx cryptoquant-mcp) for clients that cannot connect to remote MCP servers. It forwards every message to the remote server unchanged.

Remote server (recommended)

Server URL: https://mcp.cryptoquant.com/mcp (Streamable HTTP, OAuth)

No API key is needed in your config. The first time you connect, your client opens a CryptoQuant sign-in page. More setup details: CryptoQuant user guide.

Claude (claude.ai and Claude Desktop)

Open Settings → Connectors → Add custom connector and paste the server URL.

ChatGPT

Add a custom connector with the server URL (developer mode). Availability depends on your ChatGPT plan.

Cursor

Install the CryptoQuant plugin from the Cursor marketplace (once listed). It adds the remote server and the cryptoquant-onchain skill.

Or add the server yourself in .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "cryptoquant": {
      "url": "https://mcp.cryptoquant.com/mcp"
    }
  }
}

VS Code

.vscode/mcp.json:

{
  "servers": {
    "cryptoquant": {
      "type": "http",
      "url": "https://mcp.cryptoquant.com/mcp"
    }
  }
}

Claude Code

claude mcp add --transport http cryptoquant https://mcp.cryptoquant.com/mcp

Then run /mcp in Claude Code to sign in.

Local install (npx proxy)

For clients that only support local (stdio) servers. Requires Node.js 18+ and a CryptoQuant API key.

{
  "mcpServers": {
    "cryptoquant": {
      "command": "npx",
      "args": ["-y", "cryptoquant-mcp"],
      "env": {
        "CRYPTOQUANT_API_KEY": "your-api-key"
      }
    }
  }
}

| App | Config file | | --- | --- | | Claude Desktop (macOS) | ~/Library/Application Support/Claude/claude_desktop_config.json | | Claude Desktop (Windows) | %APPDATA%\Claude\claude_desktop_config.json | | Cursor | .cursor/mcp.json or ~/.cursor/mcp.json | | Claude Code | project .mcp.json |

| Variable | Required | Description | | --- | --- | --- | | CRYPTOQUANT_API_KEY | Yes | Your API key, sent to the remote server as a bearer token. If it is not set, the key saved by 0.x in ~/.cryptoquant/credentials is used. | | CRYPTOQUANT_MCP_URL | No | Overrides the server URL (default https://mcp.cryptoquant.com/mcp). Must be https; plain http is accepted only for loopback addresses (localhost, 127.0.0.1, [::1]). |

Without a key, the proxy prints setup instructions to stderr and exits.

Tools

The tools come from the remote server. This list is for reference and may change.

| Tool | Description | | --- | --- | | discover_endpoints | Find data endpoints by asset and category | | get_endpoint_info | Parameters of an endpoint (window, exchange, token, ...) | | query_data | Query on-chain, market, and derivatives data | | describe_metric | Definition, thresholds, and interpretation of a metric | | list_assets | Supported assets | | recent_research | Latest CryptoQuant Research articles | | recent_quicktake | Latest QuickTake articles from CryptoQuant Verified Authors | | query_research | Search Research articles by topic | | query_quicktake | Search QuickTake articles by topic |

Assets, dates, and rate limits

  • Assets: BTC, ETH, XRP, TRX, stablecoins, ERC-20 tokens, and other altcoins. list_assets returns the current list.
  • Dates: yyyyMMdd for window=day (e.g. 20260115), yyyyMMddTHHmmss for other windows (e.g. 20260115T000000).
  • Rate limits and history: depend on your CryptoQuant plan. The server tells the agent your plan's limits when it connects. See plans.

Migrating from 0.x

1.0 turns the npm package into a proxy to the remote server, so the local and remote servers now offer the same tools.

  • The initialize and reset_session tools are removed. Set CRYPTOQUANT_API_KEY in your MCP config instead. A key you saved in 0.x with initialize(api_key=...) keeps working; it is read from ~/.cryptoquant/credentials.
  • QuickTake and Research tools are now available locally.
  • The package no longer exports a JavaScript library API.
  • CRYPTOQUANT_API_URL (the 0.x API base URL override) is no longer used; use CRYPTOQUANT_MCP_URL to point at another MCP server.
  • npx -y cryptoquant-mcp always fetches the latest version, so existing configs switch to 1.0 on the next start. Prompts or workflows that call initialize need to be updated.

See CHANGELOG.md.
