Connect AI apps with MCP

Postwase runs an MCP server. Once connected, an AI assistant can list your projects and channels, upload images and videos, check posts against each network's rules, and save, schedule or publish posts, all with the same limits and approvals as the Postwase app.

Server address

One address for every app: https://your-postwase-domain/mcp. It speaks MCP's Streamable HTTP transport.

Two ways to sign in

Step-by-step for your app

App menus change from release to release; if a label below differs, look for the screen where you add a custom connector or MCP server.

claude mcp add --transport http postwase https://your-postwase-domain/mcp

claude mcp add --transport http postwase https://your-postwase-domain/mcp --header "Authorization: Bearer pw_live_YOUR_KEY"

What to ask

• “What Postwase projects and channels do I have?”
• “Take this image, write an Instagram and Facebook caption for our weekend sale, and save it as a draft.”
• “Import https://example.com/clip.mp4 and schedule it on TikTok (public) and YouTube Shorts for Friday 7pm.”
• “Plan next week's posts around our autumn menu and put them in the queue.” (uses the plan_week prompt)
• “Which posts failed this week, and why?” / “How did last month's posts perform?”

How uploads work

• A public link (Drive/Dropbox direct link, a CDN, a ClipForge export): upload_media_from_url.
• An image in the chat: the AI sends it inline with upload_media (up to 15 MB).
• A large video on your computer: create_upload_link returns a one-hour link to send the file to, then complete_upload. Or upload it in Postwase's Media page and ask the AI to use it (list_media).

Postwase prepares every file (size, duration, thumbnails, a JPEG or H.264 MP4 copy where a network needs one). Posts can use a file once get_media says ready.

Safety built in

• The AI has your role: a viewer can't post; an editor's posts wait for approval when the project requires it.
• Every network rule (length, media, required options) is checked before anything is saved; errors come back in plain words.
• The server tells the AI to confirm text, channels and time with you before scheduling or publishing, and to prefer drafts.
• Plan limits apply exactly as in the app. Password, billing, team and approvals stay in the Postwase app only.
• Disconnect an app in Account & security, or revoke an API key in project Settings → Developers. Access ends immediately.
