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

## What do you want YNAB and Polygon Io 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.

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.

###

### What can your agent do in Polygon Io when something happens in YNAB?

### Can it also run from Polygon Io to YNAB?

Polygon Io has no triggers in the catalog today, so automations start in YNAB. If you need the other direction, ask: your agent reads Polygon Io's API documentation and adds it.

###

###

### Can my AI client use YNAB and Polygon Io 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.
