Social media MCP server: let an AI assistant work your calendar safely

A social media MCP server lets an AI assistant such as Claude or Cursor read your real calendar, results and inbox, and, if you allow it, write drafts or schedule posts. Without one, it sees only what you paste in. The decisions that matter are how much access to grant and what stays behind a person's approval.

What an MCP server lets an assistant do

The Model Context Protocol (MCP) is an open standard for connecting AI apps to outside systems. A service runs an MCP server that offers tools; the assistant discovers them when it connects and decides which to call for your request. For a social calendar, that means answers from your data:

• "What failed this week, and why?" reads each post's status and the network's error.
• "Which Instagram posts from the last 30 days got the most comments?" reads your analytics.
• "Plan next week's posts from this article" ends as drafts in your scheduler.

Publedia's three access levels

Each Publedia API key reaches one workspace. An admin creates one in Settings, Developers, with Connect an assistant in the MCP server section, and picks a preset:

Public replies to comments are a separate Also reply to comments option, off by default. No key can send direct messages. The server lists only the tools a key allows, so an assistant on a read-only key never sees a publish tool, and no key does more than the role of the admin who created it.

Set it up in Claude, Cursor and other apps

After Create key, Publedia shows the key once, with a ready setup for the app you picked: a hidden-prompt terminal command for Claude Code, a config block for Claude Desktop, an Add to Cursor or Add to VS Code button, a command for Codex, and for Other apps the Server URL plus an Authorization header with Bearer and your key. claude.ai and ChatGPT custom connectors need OAuth sign-in, which Publedia does not offer yet, so they cannot connect today. Every step and error message is in connect Claude, Cursor or another AI app with MCP.

The server also offers three prompts: Review performance, Plan posts and Triage the inbox. MCP prompts are user-controlled, so apps show them in a menu or as slash commands. Both Plan posts and Triage the inbox tell the assistant to wait for your approval before it writes anything.

What to keep behind approval

The MCP tools specification says a human should always be able to deny a tool call, and that apps should ask before sensitive operations.

• Scheduling and publishing. With Drafts, each post waits until a person checks every channel's preview and schedules it.
• Replies to comments, above all complaints. Leave the reply option off unless someone reads each reply first.
• Cancelling. A cancelled post stops for good and cannot be rescheduled.
• Deciding what your brand says, and when it says nothing.

Risks: prompt injection and the wrong account

A key cannot touch another workspace, so it cannot post for another client. Inside its workspace, the assistant can still pick the wrong channel or post, so ask for drafts and check the channel on each. Agencies do best with one workspace per client; see keeping client accounts separate. Give each app and machine its own key, so revoking one leaves the rest working.

When not to give full control

• When the same session reads untrusted text: inbox triage, web pages, feeds.
• Before the workflow has run on Drafts until its drafts rarely need changes.
• When other people can prompt the app, or it runs unattended on a shared machine.
• For a one-off bulk change, such as moving Friday's posts to Monday: create a Full control key for the job and revoke it afterwards.

A key that can schedule but not publish can only schedule at least 15 minutes ahead, which leaves time to catch a post in the calendar. If every new article should become posts the same way, an RSS feed automation needs no assistant or key.
