# Connect Harpoon and Google Sheets

When **New Client** fires in [Harpoon](https://apiant.ai/connections/harpoon), your agent runs **Add Row** in [Google Sheets](https://apiant.ai/connections/google-sheets), or **Aggregate Metric Changed** in Google Sheets to **Add Invoice** in Harpoon. Describe the whole flow and it is built, tested on every scenario and kept running.

Harpoon **9** triggers Harpoon **46** actions Google Sheets **16** triggers Google Sheets **46** actions

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 Google Sheets 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)

### Claude, web and desktop

Open Customize, then Connectors, then Add custom connector, and paste the address. On Team and Enterprise an owner adds it first.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Cursor

Add the address to your MCP configuration as a server URL. Cursor signs you in in your browser.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Zed

Open Settings, then AI, then MCP Servers, then Add Server, then Add Remote Server.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Codex and the ChatGPT desktop app

Open Settings, then MCP servers, then Add server, and choose Streamable HTTP. From the terminal, Codex takes the address with its own add command and then signs you in.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Any other MCP client

Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection.

Questions

## Harpoon and Google Sheets, answered

###

### What can start an automation from Harpoon?

Any of Harpoon's 9 triggers in the catalog, including New Client, New Contact, New Expense and New Expense Category. Describe the moment in plain language and your agent picks the right one.

###

### What can your agent do in Google Sheets when something happens in Harpoon?

Any of Google Sheets's 46 actions, including Create Chart, Create Conditional Formatting Rule, Create Multiple Spreadsheet Rows and Create Spreadsheet. Your agent maps the data both ways and tests every scenario before it ships.

###

### Can it also run from Google Sheets to Harpoon?

Yes. When something happens in Google Sheets, your agent can act in Harpoon too. This page covers both directions: Google Sheets's triggers and Harpoon's actions are listed here as well.

###

### Do I have to build a connector for Harpoon or Google Sheets?

No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.

###

### Can my AI client use Harpoon and Google Sheets without building an automation?

Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.

###

### 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?

Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
