Frequently Asked Questions

You connect Codex to StackOne over MCP with two commands: codex mcp add stackone --url https://mcp.stackone.com/mcp registers the server, then codex mcp login stackone opens your browser to authorize — sign in, pick your project, choose accounts and actions. Same entry can go straight into ~/.codex/config.toml. Setup guide.
Codex stores the StackOne MCP server config in ~/.codex/config.toml, and codex mcp add writes it for you. The file is TOML, so the entry is a [mcp_servers.stackone] table with a single url key. It's a plain file, so IT can commit it with your dotfiles — it holds only the gateway address, never credentials.
You can connect Codex to StackOne without the browser consent step by using a session token instead of the login command. Generate one from the Connectors page in your StackOne dashboard ("Use in Agent"), then point [mcp_servers.stackone] at https://api.stackone.com/mcp?token={session_token}. Treat that URL like a credential, not the plain gateway address — it does not belong in a committed dotfile.
You don't configure each app in StackOne yourself. IT connects the apps and sets the action ceiling for your project. Running codex mcp login stackone sends you to a consent screen where you pick which of those accounts and actions to use, narrowing further if you want. Rerun the same command to change it.
Once connected, Codex can run whatever actions you granted, across 450+ live connectors and 28,000+ tested actions — CRM, HRIS, ATS, ticketing, finance, and more. Tools go live once you authorize; ask Codex what StackOne tools are available to see the list. Browse the actions in the directory above.
Your app credentials — Stripe, Salesforce, and the rest — live server-side in StackOne and never reach Codex or your machine. The gateway address in config.toml carries no access on its own, so it's safe to commit with your dotfiles. Setup asks for no client ID or secret; each token is scoped to what you picked.
IT can roll out the StackOne MCP connector to a whole team in one pass: connect the apps once, and distribute a single config.toml entry instead of briefing people individually. Each person still runs the login command, picks their own accounts and actions, and authorizes — so nobody exceeds the ceiling IT set.
Skip connecting Codex to StackOne when any of these is true:
  • An existing first-party MCP server already covers your apps
  • You use only a handful of actions across a few apps
  • You don't need multi-tenancy or per-action scoping
  • Prompt injection isn't a concern
  • Nobody can complete a browser consent step and a session token isn't an option either — a CI job, for instance
