Connect Harvest to Cursor

To use Harvest in Cursor, connect your Harvest account in Manyplug and add Manyplug to Cursor once. Cursor then gets 7 Harvest tools, for example: “Time entries”, “Log time”, and “Update an entry”. It takes about 3 minutes and works on the free plan.

Questions

Can I connect two Harvest accounts to Cursor?

Yes. Connect each one in Manyplug under its own name, for example Work and Personal. Cursor can use one of them or all at once.

Will Cursor change anything in Harvest without asking?

Changes follow your rules: you can make every change in Harvest wait for your approval, or let Cursor only read.

Do I need an official Harvest MCP server for this?

No. Manyplug connects to Harvest itself with a key or app password you paste into its form, and gives Cursor the tools through one MCP address, together with your other services.

Is it free to connect Cursor to Manyplug?

Yes. New workspaces get 14 days of Pro free, then the free plan keeps going with 150 actions a month and up to 3 connected accounts. No card needed. Paid plans start at $5 a month.

Does Cursor see my passwords or API keys?

No. Keys are entered on Manyplug’s own pages, stored encrypted with a separate key per account, and the AI only receives tool results.
