# Connect Bart and Circle

When **New service advisory** fires in [Bart](https://apiant.ai/connections/bart), your agent runs **Create Contact** in [Circle](https://apiant.ai/connections/circle), or **New Access Group** in Circle to **Find trips by origin and destination** in Bart. 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 Bart and Circle 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)

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

###

Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
