MCP & API · Available now
Unified MCP
One MCP server that lets your AI assistant post, schedule and reply across all your social accounts.
Unified MCP connects AI assistants like Claude, ChatGPT or Cursor to your Postsiva workspace at https://mcp.postsiva.com/mcp. Your assistant can draft, schedule and publish posts, read comments and check analytics on every connected network from one chat. Nothing goes live until you approve it.
What you can do
- Publish, schedule or save drafts on LinkedIn, Instagram, TikTok, Facebook, YouTube, Threads, Bluesky, Pinterest and Mastodon
- Reschedule, cancel or delete scheduled posts
- Read posts, reply to comments and pull analytics
- Upload images and videos straight from the chat
- Use Postsiva's AI content tools to write and polish captions
- Preview a post in Claude.ai or ChatGPT and pick Post, Schedule, Draft or Reject
How it works
- 01
Connect your accounts
Link the social accounts you want your assistant to use in your Postsiva workspace.
- 02
Open the MCP page
Go to Integrations → MCP in Postsiva and copy the Unified MCP URL.
- 03
Add it to your AI client
In Claude.ai, add it as a connector and sign in. For ChatGPT or a desktop/CLI client, create a workspace API key and add it as shown on the MCP page.
- 04
Ask in plain words
Try "Schedule this post on LinkedIn and Instagram for Monday 9am" and review the preview before it goes out.
Questions
Will my assistant publish without asking me?
No. In Claude.ai and ChatGPT you see a preview and choose Post, Schedule, Draft or Reject. Other clients should confirm with you before calling a publish tool.
Which AI clients work with it?
Claude.ai signs in with OAuth. ChatGPT uses a workspace API key in the URL, and desktop or CLI clients send the key in an X-API-Key header.
Is MCP on every plan?
MCP and API keys are included on plans that list them. If your plan doesn't, the MCP page will show an upgrade option.
