BankSync MCP Server

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

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

Quick Start

Get your API key at banksync.io/developers. BankSync runs as a remote MCP server — no install required:

Code

URL:       https://mcp.banksync.io
Transport: Streamable HTTP
Header:    X-API-Key: your-key

Setup

Claude Desktop

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

config.json

{
  "mcpServers": {
    "banksync": {
      "type": "http",
      "url": "https://mcp.banksync.io",
      "headers": {
        "X-API-Key": "your-key"
      }
    }
  }
}

Claude Code

Terminal

claude mcp add --transport http banksync https://mcp.banksync.io \
  --header "X-API-Key: your-key"

Cursor

Add to .cursor/mcp.json:

config.json

{
  "mcpServers": {
    "banksync": {
      "url": "https://mcp.banksync.io",
      "headers": {
        "X-API-Key": "your-key"
      }
    }
  }
}

VS Code (Copilot)

Add to .vscode/mcp.json:

config.json

{
  "servers": {
    "banksync": {
      "type": "http",
      "url": "https://mcp.banksync.io",
      "headers": {
        "X-API-Key": "your-key"
      }
    }
  }
}

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

config.json

{
  "mcpServers": {
    "banksync": {
      "serverUrl": "https://mcp.banksync.io",
      "headers": {
        "X-API-Key": "your-key"
      }
    }
  }
}

npm package (stdio fallback)

For clients that don't support remote HTTP servers, use the npm package as a local bridge:

Terminal

npx -y @banksync/mcp              # Node.js
pip install banksync-mcp && banksync-mcp  # Python

Set BANKSYNC_API_KEY=your-key as an environment variable. The package bridges stdio to https://mcp.banksync.io automatically.

Example config (any stdio client):

config.json

{
  "mcpServers": {
    "banksync": {
      "command": "npx",
      "args": ["-y", "@banksync/mcp"],
      "env": {
        "BANKSYNC_API_KEY": "your-key"
      }
    }
  }
}

What You Can Do

Ask your AI agent questions like:

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

How It Works

Code

AI Agent (Claude, ChatGPT, Cursor, ...)
    ↓ Streamable HTTP
mcp.banksync.io (Cloudflare Workers)
    ↓ Bank APIs
Plaid (US/UK/CA) · Basiq (AU/NZ)
    ↓ Sync
Notion · Google Sheets · Airtable

See docs/ARCHITECTURE.md for details.

Typical Workflow

Code

1. list_workspaces          → find your workspace
2. list_banks               → see connected banks
3. list_accounts            → discover accounts
4. get_transactions         → fetch financial data
5. list_integrations        → find your Notion/Sheets connection
6. get_data_type_schema     → discover available field mappings
7. create_feed              → set up an automated pipeline
8. trigger_sync             → run it

Data Sources

Provider	Coverage	Data Types
Plaid	US, UK, Canada — 12,000+ institutions	Transactions, balances, investments, loans
Basiq	Australia, New Zealand — 3,000+ institutions	Transactions, balances
Email extraction	Global	AI-extracted structured data from forwarded emails
File upload	Global	AI-extracted data from PDFs, images, documents

Sync Destinations

Destination	Capabilities
Notion	Sync to Notion databases
Google Sheets	Sync to spreadsheets (row or column direction)
Airtable	Sync to Airtable tables

Security

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

See SECURITY.md for our security policy and vulnerability reporting.

Debugging

Use the MCP Inspector to test and debug the server:

bash

BANKSYNC_API_KEY=your-key npx @modelcontextprotocol/inspector npx -y @banksync/mcp

Or connect the inspector directly to the remote server:

Terminal

npx @modelcontextprotocol/inspector --url https://mcp.banksync.io --header "X-API-Key: your-key"
