Bring your subscriptions

If you already pay for Claude, ChatGPT or Cursor, you can use that plan in aixplain Desktop, and the work counts against your plan instead of your aixplain credits. You can also go the other way: let Claude Code, Codex and other agents start and read Koder sessions. This article explains how to connect a plan, how to check its status, how usage counts and how to let other agents work with Koder safely.

Use your Claude, ChatGPT or Cursor plan

The app runs each vendor's own CLI with the sign-in you already have, so there are no new keys to manage.

1. Install the vendor's CLI from the table above, on the same computer as the app.
2. Sign in to it with your plan's account.
3. Open aixplain Desktop. It finds installed CLIs automatically, including ones behind version managers.
4. Pick the plan's model in the model picker.

Check your plans

Open Settings → Models & providers → Your subscriptions, or run koder providers subs in the terminal. Each plan shows its account and plan with a status:

• Ready: you can pick its models.
• Not signed in or Not installed: the app shows the one command that fixes it, with Run in a terminal and Copy command.
• No models or Needs attention: the plan is connected but has nothing to offer right now. Follow the hint next to it.

Under Other accounts, you can add a second login for the same vendor, such as a work and a personal account. More agents adds other coding agents, such as Gemini CLI and OpenCode.

How usage counts

Usage on a connected plan counts against that plan's limits, not your aixplain credits. The usage page shows your Koder, Claude Code and Codex usage together, with your plan limits. Each limit window says whether you're ahead of it, behind it or on pace. Which models you can pick depends on what your plan offers.

Let other agents work with Koder

Koder can act as an MCP server, so agents such as Claude Code and Codex can start Koder sessions, send them messages and read what they did. Each agent signs in with a one-time pairing code and gets a scope it can never exceed.

Turn it on

1. Open Settings → Connections.
2. Turn on Let outside agents connect. It's off by default.
3. Copy the MCP URL.

In the terminal, run koder mcp server on instead.

Add an agent

Add Koder to the agent with the MCP URL, then sign in:

claude mcp add --transport http koder <mcp-url>
claude mcp login koder

codex mcp add koder --url <mcp-url>
codex mcp login koder

1. In Settings → Connections, under Pairing code, select Create code, or run koder mcp pair. Each code works once, for 10 minutes.
2. In the sign-in page the agent opens, enter the code.
3. Under What it may do, choose a scope, then select Allow.

Choose what an agent may do

Koder enforces the scope on its side, so an agent can't go beyond it whatever it asks for.

Change or revoke access

Under Signed-in agents, open an agent to change What it may do, or select Revoke to remove its access at once. An agent that hasn't connected for 30 days loses access on its own. Turning the server off keeps each agent's access for when you turn it back on.

Limitations

• A plan needs its vendor's CLI installed and signed in on the same computer as the app.
• The models you can pick from a plan depend on what that plan offers.
• Outside agents start Koder sessions, not Omni sessions.
• The MCP server runs on your computer. An agent on another machine needs an https address that reaches it, such as a tunnel you run.
