Connect BankSync to Warp

Warp supports MCP servers through its agent configuration. You can add BankSync via the MCP Gallery or manual JSON config. See the Warp MCP docs for more details.

Prerequisites

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

Manual Configuration

Add the following to your Warp MCP configuration:

Warp MCP Config

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

Verify Your Connection

After configuring your client, restart it and try these prompts to verify the connection is working:

“List my workspaces”

“What banks do I have connected?”

“What’s my checking account balance?”

Troubleshooting

“No tools available” or MCP server not listed

Make sure you restarted your AI client after editing the configuration file.
Verify the JSON is valid (no trailing commas, correct brackets).
Check that 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Confirm the key starts with bsk_ and has not been revoked.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 in the headers object under X-API-Key.
Check for accidental whitespace or newlines around the key value.

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.

Connection timeout or network errors

The MCP server uses Streamable HTTP transport. Ensure your network or proxy allows outbound HTTPS connections.
If using a VPN or firewall, allow connections to mcp.banksync.io.
Try the connection from a different network to rule out local issues.
