Use Portaxo from Claude, Codex or ChatGPT

Claude on the web, desktop and phone

A link opens Claude's add-connector dialog with Portaxo's name and URL already filled in. Add it once on claude.ai and it is in the Claude desktop and phone apps too, under the same Claude account.

• Claude desktop app. A connector added on the web shows up in a desktop app that is already open only after a refresh (Ctrl+R) or a restart.
• Permissions. Claude asks before each tool runs. “Always allow” applies to that one tool; to set every tool at once, open Customize → Connectors → Portaxo. The tools table suggests a setting for each.
• Team and Enterprise. Only an Owner can add a custom connector, using the admin version of the link. Each member then finds Portaxo under Customize → Connectors, clicks Connect and signs in to their own Portaxo account.
• Claude Free. The Free plan allows one custom connector.

Claude Code (command line)

Anthropic's coding agent, in your terminal. One command adds Portaxo, and you sign in from inside Claude Code.

claude mcp add --transport http portaxo https://api.portaxo.com/mcp

• Added it on claude.ai already? When Claude Code is signed in with the same Claude account, the connectors you added on claude.ai show up in its /mcp list too, so Portaxo may be there without the command.

claude mcp add --transport http portaxo https://api.portaxo.com/mcp --header "Authorization: Bearer TOKEN"

ChatGPT

• OpenAI's own documentation is unclear about which ChatGPT plans may use tools that change things, such as unlocking contacts or launching a campaign. If yours cannot, use Claude or Codex.

Apps with an access token: WorkBuddy, QwenWork, Doubao, Cursor, VS Code

Apps that cannot run Portaxo's browser sign-in connect with a personal access token. It is also the way in from mainland China, Hong Kong and Macau, where Claude, Codex and ChatGPT are not offered. A token acts as you, with the same reach as a signed-in app, so treat it like a password.

• A person can hold at most 10 tokens. Tokens do not expire; revoke one in the same tab when you stop using its app.
• Changing or resetting your password, or Log out all, revokes every token and disconnects every app at once.
• These configs are plain-text files on your computer. Do not commit them to a repository or send them to anyone.
• Menu names below can differ a little between versions of each app.

Any other app that speaks MCP over Streamable HTTP works: it sends a POST to the server URL with Authorization: Bearer TOKEN, Content-Type: application/json, and an Accept header listing both application/json and text/event-stream.
