# Connect OpenAI to Anthropic

When **New batch** fires in [OpenAI](https://apiant.ai/connections/openai), your agent runs **Create message batch** in [Anthropic](https://apiant.ai/connections/anthropic). Describe the whole flow and it is built, tested on every scenario and kept running.

OpenAI **5** triggers OpenAI **69** actions Anthropic **9** actions

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

## What do you want OpenAI and Anthropic 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.

OpenAI and Anthropic both sit in the same workflows, and joining them lets one account react to what happens in the other. A new file, batch, model or video in OpenAI can kick off a message to Claude in Anthropic, a token count before you commit to a request, or a batch of Messages API requests. The agent builds the flow, tests every scenario and keeps it running.

Questions

## OpenAI and Anthropic, answered

###

### Can a workflow start from something happening in Anthropic?

No, Anthropic has no triggers on this platform, so every flow here starts in OpenAI: a new file, batch, model, vector store or video. Anthropic comes in on the action side, sending a message to Claude, counting tokens, or creating and checking message batches.

###

### Can I send an OpenAI file's contents to Claude?

Yes, OpenAI has a Get file content action that returns the file's contents, and that text can be passed into Anthropic's Send model a message action. You can also run the reply back through OpenAI content moderation before storing or posting it.

###

### What can start an automation from OpenAI?

Any of OpenAI's 5 triggers in the catalog, including New batch, New file, New model and New vector store. Describe the moment in plain language and your agent picks the right one.

###

### What can your agent do in Anthropic when something happens in OpenAI?

Any of Anthropic's 9 actions, including Anthropic agent message, Create message batch, List models and Send model a message. Your agent maps the data both ways and tests every scenario before it ships.

###

### Can it also run from Anthropic to OpenAI?

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

###

### Do I have to build a connector for OpenAI or Anthropic?

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 OpenAI and Anthropic 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.
