Postdom's social media MCP server for your AI agent
Postdom's social media MCP server connects your AI agent to your social accounts. It can make slideshows on your brand kit, publish videos and images, schedule them and read each result, while you keep the approval and the rules.
Updated
A social media MCP server gives an AI agent such as Claude, ChatGPT or Cursor a standard set of tools to publish posts, schedule them and read results on your social accounts. Postdom's hosted server has 17 tools, publishes to nine platforms and keeps you in charge of approval.
Connect the hosted MCP server: 17 tools
Postdom's hosted MCP server at https://api.postdom.com/mcp has all 17 tools, including create_slideshow, which makes a slideshow on your brand kit from slides your agent writes. Nothing to install: clients that support MCP sign-in connect to your workspace, and any client can send a workspace key instead.

What is a social media MCP server?
A social media MCP server is a server that speaks the Model Context Protocol, the standard AI agents use to call outside tools, and exposes tools for social accounts: list the accounts, publish a post, schedule it and read what happened. Postdom's server does that for TikTok, Instagram Reels, YouTube Shorts, LinkedIn, Facebook Reels, X, Snapchat Stories, Threads and Bluesky, and it adds create_slideshow, which makes the post on your brand kit from slides the agent writes.
What Postdom's social media MCP server does
Publish within your rules
Submit a finished video for review, or act inside a plan you approved. The agent can't approve its own work.
Check the result
Read each account's outcome and the performance a platform reports, with missing values kept missing.

Social media MCP server
Postdom's hosted MCP server is https://api.postdom.com/mcp. It has all 17 tools and needs nothing installed: clients that support MCP sign-in connect to your workspace, and any client can send a workspace key instead.
Clients that only start local servers can run the published package @postdom/mcp@0.5.0, which has the original 17 tools and needs Node.js 22 or newer and a workspace key:

Social media for AI agents
The hosted server exposes 17 tools, grouped by job: understand the workspace, choose an account, make or upload media, submit and follow up, and read performance. The table near the top of this page lists every one.
Over MCP, your agent can make slideshows and publish them: create_slideshow draws the slides your agent writes on your brand kit, and publish_video posts them or a finished video you supply. The videos Postdom writes from your website are made in the app, and every post waits for the approval its account needs.
A response is not a publication
accepted, requires_approval and scheduled are workflow states. Keep the returned post ID and read it with get_publish until each destination reports published or failed.
An agent cannot approve itself
You own the accounts, the rules and the approval. Your agent prepares the request; you decide what goes out.
A missing metric is not a zero
When a platform does not report a value, Postdom marks it unavailable with the reason, and leaves it out of totals.
TikTok MCP
Through Postdom's MCP server, an agent can publish to a TikTok account you connected in Postdom: a finished video, or several images as a photo post, with a caption. It can make the slides first with create_slideshow, publish them with publish_video and read the outcome with get_publish. TikTok posts go out public with comments, duets and stitches off, and the AI-made label is off by default; you can turn it on in Settings.
Every TikTok limit and setting is in the TikTok destination reference.
Instagram MCP
On Instagram, the agent publishes Reels and feed posts to a professional account connected in Postdom: one video as a Reel, or several images as a carousel. create_slideshow makes the slides on your brand kit, publish_video sends them with the caption, and get_publish returns the link once Instagram confirms the post. Instagram's AI label is off by default, and any post the account's review level holds waits for a person to approve it.
Every Instagram limit and setting is in the Instagram Reels destination reference.
