How it works

How Postproxy works inside Claude

01 Add it from the Claude directory
Open Postproxy in the Claude connector directory, click Connect, and sign in with your Postproxy account — one click and the tools appear. (Prefer the terminal? Claude Code uses the API-key setup below.)
02 Link your social accounts
Ask Claude "connect my Instagram account" and it returns a link — platform OAuth lives in Postproxy, so your logins stay in your Postproxy account.
03 Ask in plain language
"Post this to X and LinkedIn at 9am tomorrow." Claude calls the Postproxy tools and confirms before anything goes out.
04 Postproxy executes
We handle platform rules, media, rate limits, and retries, and return per-platform results to the conversation.
