Claude Desktop

Install the BCA Crypto Brain MCP in Claude Desktop in under a minute. Once installed, Claude can call any of the 99 BCA tools directly from a chat — no extra UI, no copy-paste.

1. Install

BCA ships as a zero-install npx package. No global install, no Docker, no Python.

npx -y @blockchainacademics/mcp

The first run downloads the package and prints a usage banner. Press Ctrl+C — you only ran it once to prime the npm cache. Claude Desktop invokes it on demand.

2. Add to your Claude Desktop config

Open your Claude Desktop config file:

~/Library/Application Support/Claude/claude_desktop_config.json

%APPDATA%\Claude\claude_desktop_config.json

~/.config/Claude/claude_desktop_config.json

Paste the following (or merge into your existing mcpServers block):

{
  "mcpServers": {
    "blockchainacademics": {
      "command": "npx",
      "args": ["-y", "@blockchainacademics/mcp"],
      "env": {
        "BCA_API_KEY": "bca_YOUR_KEY_HERE"
      }
    }
  }
}

3. Restart Claude Desktop

Fully quit Claude Desktop (not just close the window — on macOS, Cmd+Q) and relaunch. You should see a small hammer icon in the chat input bar — click it and confirm blockchainacademics appears with 99 tools listed.

4. Try it

In a new chat, paste:

“Use the BCA tools to summarize this week’s regulatory news on Circle, with citations.”

Claude will call search_news with entity="circle" and topic="regulation", then assemble a cited summary. Every quoted fact links back to a blockchainacademics.com article via the cite_url field in the response envelope.
