MCP connector for Claude

TOConline

Read-only access to a TOConline company: customers, issued invoices and other sales documents, unpaid balances, monthly sales totals and the product and service catalogue.

Add it to Claude

1. Create an account and add credits at https://openjack.dev; copy your connection key.
2. In Claude, open Settings → Connectors → Add custom connector and paste https://toconline.openjack.dev/mcp.
3. Click Connect. You will be asked for the connection key and your TOConline credentials.

How your data is handled

Your TOConline credentials are validated once, then stored encrypted with a key that only the token issued to your Claude account can unwrap. Disconnecting the connector in Claude revokes that token. The connector keeps no logs and no cache, and stores none of the data it passes to Claude. Every tool is read-only.
