Questions

Can I connect two Harvest accounts to Windsurf?

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

Will Windsurf change anything in Harvest without asking?

Changes follow your rules: you can make every change in Harvest wait for your approval, or let Windsurf 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 Windsurf the tools through one MCP address, together with your other services.

Is it free to connect Windsurf 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 Windsurf 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.
