BankSync

Connect BankSync to Continue

Connect BankSync MCP server to Continue, the open-source AI code assistant, for fintech development with real bank data.

Prerequisites

  • A BankSync account with at least one connected bank
  • An API key with all permission scopes (created from Workspace → Developers)

Configuration

Add the BankSync server to your Continue MCP configuration, replacing the placeholder with your API key:

MCP config (YAML)
mcpServers:
  - name: BankSync
    type: streamable-http
    url: https://mcp.banksync.io
    requestOptions:
      headers:
        X-API-Key: bsk_your_api_key_here

Where it goes: ~/.continue/config.yaml (global)

Tip. Continue uses YAML format with mcpServers as a list (not an object). Headers must be nested under requestOptions.headers, not at the top level.
Server URL. BankSync’s MCP server is at https://mcp.banksync.io over Streamable HTTP, authenticated with your X-API-Key. If Continue can’t reach a remote server, use the local bridge npx -y @banksync/mcp with BANKSYNC_API_KEY set.

Verify your connection

Restart your client and try these prompts to confirm the connection works:

“List my workspaces”
“What banks do I have connected?”
“What’s my checking account balance?”

Troubleshooting

“No tools available” or the MCP server is not listed

  • Make sure you restarted your AI client after editing the config file.
  • Verify the JSON/YAML is valid (no trailing commas, correct brackets).
  • Check the URL is exactly https://mcp.banksync.io.

“Authentication failed” or “Invalid API key”

  • Confirm the key starts with bsk_ and has not been revoked.
  • Ensure the key is passed in the X-API-Key header.
  • Check for stray whitespace or newlines around the key value.

Connection timeout or the client lacks remote HTTP support

  • The server uses Streamable HTTP. Allow outbound HTTPS to mcp.banksync.io.
  • If your client only supports local servers, use the npm bridge: npx -y @banksync/mcp.

Tools are listed but return errors

  • Verify your API key has the required scopes — for full access, select all scopes when creating the key.
  • Make sure you have at least one bank connected in the BankSync app.
  • Check that you are passing the correct workspace ID when prompted.

Debugging with MCP Inspector

  • Use the MCP Inspector to test the connection independently of your AI client.
  • Run: npx @modelcontextprotocol/inspector --url https://mcp.banksync.io--header "X-API-Key: bsk_your_key"
  • If the Inspector connects but your client does not, the issue is your client configuration.
