GenStudio + Codex

Your creative workspace.
Connected to Codex.

Find the right workflow, estimate its credit cost, and check your generation progress without leaving your conversation.

No account token needed

Explore and estimate

Connect the public MCP endpoint to discover workflows and calculate standard credit estimates. These tools do not start jobs or spend credits.

codex mcp add genstudio --url https://genstudio.web.app/api/mcp

Transport: Streamable HTTP. You can also enter the endpoint URL in Codex MCP settings.

Private account connection

Stay in sync

Read your credit balance, projects, task history, and generation progress with a revocable account token.

Sign in to GenStudio.
Open Account → Settings → Use GenStudio in Codex.
Create a token and follow the connection instructions.

Open GenStudio

Connect your account

Set GENSTUDIO_MCP_TOKEN in the environment used to launch Codex. Keep the token private and out of source control. Then add the server:

codex mcp add genstudio --url https://genstudio.web.app/api/mcp --bearer-token-env-var GENSTUDIO_MCP_TOKEN

Or add this to your Codex config.toml:

[mcp_servers.genstudio]
url = "https://genstudio.web.app/api/mcp"
bearer_token_env_var = "GENSTUDIO_MCP_TOKEN"

If you previously added public access, update that server's configuration to include the environment variable. Restart Codex after changing its environment. Use codex mcp list to confirm the configuration.

Try it

“Which GenStudio workflow should I use for a 3D game asset?”
“Estimate the credits for two sound effects.”
“Show my GenStudio tasks and their progress.”

Generation and downloads

MCP provides discovery, estimates, and read access. Start generation and download files in the GenStudio workspace: those operations require its browser-to-worker WebRTC connection. Estimates use the standard tariff; the app confirms your account entitlements and final charge.

Reconnect or revoke access

If a token is lost or rejected, replace it in Account Settings and update the Codex environment. Replacement revokes the previous token immediately. Revoke the token to remove account access. A configured server is not proof of a working connection; ask Codex to list the GenStudio workflows to verify it.
