Connect freee and Simplicate
When New manual journal fires in freee, your agent runs Update Contact in Simplicate, or New Companies in Simplicate to Add deal in freee. Describe the whole flow and it is built, tested on every scenario and kept running.

Connect your AI client
Give your AI client this address.
https://mcp.apiant.aiOne connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

Can my AI client use freee and Simplicate without building an automation?

What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
