Agent setup

Set up DoDomain in Codex

The fast way: copy this sentence into Codex and let it do the setup below itself.

Add to Claude

Connect the MCP server

  1. 1. Register the DoDomain MCP server

    codex mcp add dodomain --url https://app.dodomain.io/api/mcp
  2. 2. Sign in to DoDomain (opens the browser for the OAuth consent)

    codex mcp login dodomain

Sign in. codex mcp login dodomain opens the DoDomain sign-in and consent page in the browser and stores the token for later sessions. No API key is involved: the MCP server uses OAuth and refuses secret keys by design.

What you get

Install the SDK

Server code uses a secret key from DODOMAIN_SECRET_KEY. Create an app at https://app.dodomain.io/dashboard and copy the secret key from its API keys card. It is shown once.

Verify

After signing in, ask the agent to call the list_apps tool: it lists the apps on your team. To check a secret key, run:

curl -s https://app.dodomain.io/api/v1/apps -H "Authorization: Bearer $DODOMAIN_SECRET_KEY"

Success is HTTP 200 with a JSON body of the form {"apps": [...]}: a secret key sees exactly its own app, with its id, name and publishable key.

Start on the free plan

No card, no sales call: create an app, mint a session, and watch the first domain verify.
