# Connect Harpoon and inFlow Inventory

When **New Client** fires in [Harpoon](https://apiant.ai/connections/harpoon), your agent runs **Create a Sales Order** in [inFlow Inventory](https://apiant.ai/connections/inflow-inventory), or **New or Updated Customer** in inFlow Inventory to **Add Invoice** in Harpoon. Describe the whole flow and it is built, tested on every scenario and kept running.

What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.

## What do you want Harpoon and inFlow Inventory to do together?

Give your AI client this address.

`https://mcp.apiant.ai`

One 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.

### Set it up in your client

### Claude Code

Run this in the directory you want to work in.

`claude mcp add --transport http -s project apiant-ai https://mcp.apiant.ai`

Start Claude Code there, approve the server, and sign in in the browser page it opens.

[Claude Code guide (opens in a new tab)](https://apiant.ai/docs/mcp/claude-code)
