Connect Codex to Tensorbasis

Configure a remote Streamable HTTP server in the configuration shared by local Codex clients.

No Tensorbasis CLI, local server or installation required for HTTP clients.

Setup

  1. Open your Codex MCP settings or your private ~/.codex/config.toml. A trusted project can use project-scoped configuration instead.
  2. Add the tensorbasis server with the hosted URL using the configuration below. This does not launch a local process.
  3. When Tensorbasis OAuth is available, use the client's sign-in flow. The optional Codex command is: codex mcp login tensorbasis. If it fails, do not treat the server as connected.
  4. For a key fallback, add bearer_token_env_var = "TENSORBASIS_API_KEY" to this server's table and set that variable securely in the environment of the Codex host. Keep keys out of project files and chat.
  5. Check that the server exposes tools, then request only an account summary as the first verification.

Configuration reference

Merge with your existing settings. Examples contain no real credentials.

Compatibility and transport

This is the local Codex host configuration path documented by OpenAI, not a claim that a ChatGPT browser plugin is installed. Browser-hosted tools have separate setup and availability. Tensorbasis has not certified an end-to-end session in every Codex surface.

Configuration guidance is based on the official documentation linked below, reviewed 31 October 2026. Tensorbasis has not completed an end-to-end verification in this client. Client versions, account eligibility and organization policies can change the available setup.

If it does not connect

  • Check that the URL ends in /api/mcp and the transport is HTTP, not stdio or a legacy SSE-only URL.
  • Check sign-in or the bearer key, its scopes and expiry. Never send a key to support in a screenshot.
  • If OAuth is not available in your deployed server/client pair, use the documented key fallback where headers are supported. Do not invent a callback URL or assume a browser connector can accept a local command.
  • A visible tool list is only discovery. Verify a read-only result from your account before requesting any action.
