Does Post Bridge Have an MCP Server?
Short answer: check their current docs, because this moved fast in 2026. What is certain: Socialync runs a native MCP server on every plan, free included, so Claude, ChatGPT, Cursor, and any AI agent can post to 8 of the 9 platforms Socialync supports. Socialync tells your AI to get your yes before each post, and in AI clients that support it you can switch on a confirmation dialog on the API Keys page.
The short version
Post Bridge runs an MCP server with 16 tools that schedules posts, reads analytics and manages accounts. It is listed in the Claude connector directory, has a ChatGPT app, and signs in with OAuth or an API key. The MCP server and API come with its $39 Marketer plan.
Socialync runs a native MCP server on every plan, free included. Add the URL to Claude, ChatGPT, or Cursor and sign in with OAuth (or paste an API key in a client that cannot open a browser), and your assistant can draft, schedule, and publish across every platform you have connected except Pinterest. That is what this page is about.

How posting from your AI works
Add the server URL
Point Claude, ChatGPT, Cursor, or any MCP client at https://mcp.socialync.io/mcp. Sign in with your Socialync account in the browser and pick which brands the assistant may manage. No keys to copy.
Or use an API key
Clients that cannot open a browser (Grok Bot, headless agents, hand-edited config files) use an API key from Socialync settings as a Bearer token instead. One active key per account, limited to the brands you pick, revocable any time.
Post in plain English
Tell your AI what to publish. It shows you the exact post and publishes after your yes in chat, or saves a draft you approve in the app.
