Shop from your assistant

Connect OCA to ChatGPT, Claude or your coding agent. Ask it to buy something, and you still approve every payment here.

Easiest

Paste this into your assistant

Your assistant adds OCA itself, or opens its settings and does it for you, or walks you through it.

Add the OCA MCP server so you can buy things for me.

URL: https://oca.dev/mcp
Type: remote HTTP (streamable). Sign-in: OAuth in the browser, no API key.

1. If you can add MCP servers with your own tools, add it and confirm it's connected.
   Codex: codex mcp add oca --url https://oca.dev/mcp
   Claude Code: claude mcp add --transport http --scope user oca https://oca.dev/mcp (then I sign in with /mcp)
2. If you can't, but you can use a browser or my computer, open your app's settings and add it as a custom connector named OCA with the URL above. Stop at the sign-in screen so I can approve it.
3. Otherwise, walk me through adding it in your settings, one step at a time.

If you're Grok Bot: once it's connected, also turn on OCA updates, so you can tell me when a checkout needs me even after this chat. Call grok_bot_updates_setup, create the routine it describes with a webhook trigger, then ask me to paste the routine's Webhook URL and Webhook key at https://oca.dev/settings/notifications#grok-bot.

Works in ChatGPT, Claude, Grok and other assistants.

Or set it up yourself

Open Plugins and choose + → Add custom MCP server. Not there? Turn on Developer mode in Settings first.
Name it OCA, paste the URL and pick OAuth.
Choose Create as a plugin, then sign in to OCA and allow access.

Assistants never see card numbers or passwords. You approve every payment on OCA, and you can disconnect an assistant anytime from Settings.
