Quick install

1. Get an API key

Log in at app.nexusquantum.finance → Settings → API Keys → create a key. Copy the nf_... key — shown only once.

2. Configure your client

Claude Desktop (macOS / Windows)

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "nexus-finance": {
      "command": "npx",
      "args": ["-y", "@nexus-finance/mcp"],
      "env": {
        "NEXUS_FINANCE_API_KEY": "nf_YOUR_KEY_HERE"
      }
    }
  }
}

Restart Claude Desktop. You'll see a 🔌 icon in the chat with the 8 Nexus Finance tools available.

Claude Code (CLI)

claude mcp add nexus-finance -- npx -y @nexus-finance/mcp
# Then set your key:
export NEXUS_FINANCE_API_KEY=nf_YOUR_KEY_HERE

Cursor

Edit ~/.cursor/mcp.json:

{
  "mcpServers": {
    "nexus-finance": {
      "command": "npx",
      "args": ["-y", "@nexus-finance/mcp"],
      "env": {
        "NEXUS_FINANCE_API_KEY": "nf_YOUR_KEY_HERE"
      }
    }
  }
}

3. Try it

In Claude Desktop, type:

Audit this contract with Nexus Finance and flag any high-risk clauses: «[paste contract text here]»
