banksync-mcp

Connect AI agents to real bank accounts — transactions, balances, investments, and loans — across 15,000+ financial institutions.

banksync-mcp is a Model Context Protocol server with 28 tools that gives Claude, ChatGPT, Cursor, VS Code, and other AI agents secure access to your financial data. Sync to Notion, Google Sheets, and Airtable — all through conversation.

Installation

pip install banksync-mcp

Or with uv:

uv pip install banksync-mcp

Requires Python 3.10+ and a BANKSYNC_API_KEY environment variable. Get your API key at banksync.io/developers.

Quick Start

export BANKSYNC_API_KEY=your-key
banksync-mcp

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "banksync": {
      "command": "banksync-mcp",
      "env": {
        "BANKSYNC_API_KEY": "your-key"
      }
    }
  }
}

Claude Code

claude mcp add banksync -e BANKSYNC_API_KEY=your-key -- banksync-mcp

Cursor / VS Code / Windsurf

{
  "mcpServers": {
    "banksync": {
      "command": "banksync-mcp",
      "env": {
        "BANKSYNC_API_KEY": "your-key"
      }
    }
  }
}

For clients that support remote MCP servers, you can connect directly to https://mcp.banksync.io with an X-API-Key header instead. See setup guides.

Usage

Ask your AI agent:

• "What were my biggest expenses last month?"
• "How much do I have across all my accounts?"
• "Sync my transactions to Notion every week"
• "Show my investment portfolio performance"
• "What's my outstanding loan balance?"

How It Works

This package is a thin stdio-to-HTTP bridge. It validates your API key and forwards MCP messages to https://mcp.banksync.io using the mcp SDK's async streamable HTTP transport. No financial data is stored locally.

Security

• API key authentication scoped per workspace
• All data encrypted in transit (TLS)
• Role-based permissions (owner/admin/editor/viewer)
• Banking credentials delegated to Plaid/Basiq — never stored by BankSync
• Stateless MCP transport — no session data persisted
