RepeatPost MCP Server

Official
by repeatpost

Overview

RepeatPost MCP is a remote, hosted Model Context Protocol server. Add one URL to your AI assistant, sign in to RepeatPost in your browser, and choose what the assistant may do. It then works with the channels connected to your RepeatPost workspace and stays within your workspace role.

There is nothing to install or run. This repository holds the server's public metadata and documentation, not its source code. The server itself runs at https://api.repeatpost.com/mcp.

Key features

  • Publish to 15 platforms. Create drafts, schedule, publish, edit and reschedule posts on any connected channel. Send one post to several channels at once as a post group, with a status for each channel and a retry for the failed ones.

  • Captions in your brand voice. The assistant writes ready-to-publish captions in the brand voice that applies. Each caption costs 1 AI credit.

  • Branded graphics without an image model. The assistant designs a layout as SVG and RepeatPost renders it to a PNG, using your brand colours and logo. It can also add your logo to a photo.

  • Media library. Search, browse, upload, organise, rename, favourite and delete files and folders.

  • Workspaces and brand voices. List and switch workspaces, see which brand voice applies, and set the default one.

  • You choose the permissions. Five OAuth scopes, each with its own checkbox on the consent screen. The workspace role is always the ceiling, and channel approvals still apply.

  • Standard MCP sign-in. OAuth 2.1 with dynamic client registration and PKCE. Credentials never pass through the AI client or the model.

  • Annotated tools. Every tool carries MCP tool annotations, so clients can ask before running destructive ones.

What it doesn't do

  • AI images and videos. Create them in the RepeatPost app, then ask your assistant to schedule them from the media library.

  • Connecting channels. Connect social channels in the RepeatPost app.

  • Accounts and billing. Create an account and change plans in the RepeatPost app.

Installation and setup

There is nothing to install. You add the server URL to your AI client and sign in.

Before you connect

  • You need a RepeatPost account.

  • Connect your social channels in the RepeatPost app first. An assistant can only use channels that are already connected.

Connect in four steps

  1. Add https://api.repeatpost.com/mcp as a remote MCP server in your client. See Client configuration.

  2. Sign in to RepeatPost on the page your client opens in the browser.

  3. On the consent screen, untick anything you don't want to allow, then approve. See Permissions (OAuth scopes).

  4. Ask your assistant to do something, for example one of the example workflows.

Authentication and OAuth

The server uses the standard MCP authorization flow. Credentials never pass through the AI client or the model: the user signs in on RepeatPost's own page in their browser, and the client receives OAuth tokens.

  1. An unauthenticated request to /mcp returns 401 with a WWW-Authenticate header that points to the protected resource metadata.

  2. The client reads the metadata, registers itself (RFC 7591 dynamic client registration) and opens the authorization page in the browser.

  3. The user signs in, reviews the consent screen and approves.

  4. The client exchanges the authorization code for tokens (PKCE S256) and calls /mcp with Authorization: Bearer <access_token>.

The scopes a token can carry are listed under Permissions (OAuth scopes).

Client configuration

Claude (web and desktop)

  1. In Claude, open Settings, then Connectors, and select Add custom connector.

  2. Paste https://api.repeatpost.com/mcp and select Connect.

  3. Sign in to RepeatPost on the page that opens.

  4. On the consent screen, untick anything you don't want to allow, then approve.

Claude Code

claude mcp add --transport http repeatpost https://api.repeatpost.com/mcp

Then run /mcp in Claude Code, select repeatpost and authenticate in your browser.

Cursor

Add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "repeatpost": {
      "url": "https://api.repeatpost.com/mcp"
    }
  }
}

VS Code

Add this to .vscode/mcp.json:

{
  "servers": {
    "repeatpost": {
      "type": "http",
      "url": "https://api.repeatpost.com/mcp"
    }
  }
}

Clients that only support stdio

Use mcp-remote as a bridge:

{
  "mcpServers": {
    "repeatpost": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://api.repeatpost.com/mcp"]
    }
  }
}

Any other MCP client

Any client that supports remote MCP servers with OAuth sign-in can connect. Add a remote server with the URL https://api.repeatpost.com/mcp and sign in when asked.

Example workflows

  • "Schedule a post about our weekend sale to Instagram and LinkedIn for Friday at 9am."

  • "Make a square post announcing our 20% weekend sale in our brand style and save it as a draft."

  • "Add our logo to the summer product photo in my media library."

  • "What's scheduled for next week, and did any posts fail?"

  • "Write three LinkedIn captions about our new feature in our brand voice."

Tool permissions and security

Permissions (OAuth scopes)

The consent screen lists five permissions, each with its own checkbox. A token carries only the scopes the user approved.

Scope

Shown on the consent screen as

Allows

mcp:read

View your workspaces, channels, posts, media and credits

Looking things up. Changes nothing on its own.

mcp:write

Create and edit drafts, media, folders and brand voice settings

Preparing work: drafts, uploads, folders, graphics and brand voice changes

mcp:publish

Schedule and publish posts to your channels

Putting posts on the schedule or publishing them now

mcp:delete

Delete posts and media

Removing posts and media

mcp:ai

Generate captions (uses your AI credits)

Writing captions. Each caption costs 1 AI credit.

Two rules apply whatever the user approves:

  • The workspace role is the ceiling. An assistant can never do more than the user's role allows. A Viewer can only read.

  • Approvals still apply. If posts on a channel need approval, posts scheduled there by an assistant go to approval first.

Security and privacy

  • Sign-in happens on RepeatPost's own page. The assistant never sees the user's password.

  • Each token carries only the permissions the user approved, and never more than the user's workspace role.

  • By default, deleting a post removes it from RepeatPost only. Deleting it on the platform as well needs an explicit request from a workspace Owner.

  • To disconnect, remove the RepeatPost connector in your assistant's settings, or email support@repeatpost.com to have its access revoked.

Read AI assistants and connectors in the RepeatPost Privacy Policy, and the Terms of Service.

To report a security issue, follow SECURITY.md or email support@repeatpost.com.

Troubleshooting

Problem

What to do

The client asks you to sign in, or reports 401

This is how sign-in starts. Finish signing in on the RepeatPost page in your browser. In Claude Code, run /mcp, select repeatpost and authenticate.

You are asked to sign in again after a long break

Refresh tokens last 30 days and are rotated on every refresh. After 30 days without use, sign in again.

A channel is missing

Connect it in the RepeatPost app. An assistant can only use channels that are already connected.

An action is refused for permissions

The scope wasn't approved on the consent screen, or your workspace role doesn't allow it (a Viewer can only read). Reconnect and approve the scope, or ask a workspace Owner.

A scheduled post went to approval

The channel needs approval, and posts scheduled there by an assistant go to approval first.

Captions aren't being written

Each caption costs 1 AI credit. Ask your assistant for your credit balance.

A post was deleted in RepeatPost but is still on the platform

This is the default. Deleting it on the platform as well needs an explicit request from a workspace Owner.

Your client only supports stdio servers

Use mcp-remote as a bridge. See Clients that only support stdio.

You want to disconnect

Remove the RepeatPost connector in your assistant's settings, or email support@repeatpost.com to have its access revoked.

Related MCP Connectors

  • Draft and schedule social media posts on your connected channels from Claude or any MCP client.

  • Schedule and publish social posts across 9 platforms (Instagram, LinkedIn, X, TikTok, Facebook, Threads, Pinterest, Bluesky, Mastodon) straight from Claude, ChatGPT, Cursor, or any MCP client. Create, edit, and reschedule posts, upload media, and pull account and post analytics, follower demographics, and best-time windows. 20 tools, free on every plan.

    https://mcp.nuntior.com/mcp
  • SocialFaktory (https://www.socialfaktory.com) is a social media MCP server that lets your AI agent run a brand's social content with you. It reads the brands, channels and media you already have, writes posts in the brand's own voice, prices and generates short video, takes a file you upload, composes one post per channel, schedules or sends it on TikTok, Instagram, YouTube, X, LinkedIn, Facebook and Pinterest, and reads the metrics back. It is a hosted remote server at https://www.socialfaktory.com/mcp (Streamable HTTP) with OAuth 2.1 sign-in and 20 tools. Install steps cover Claude Code, Claude Desktop, Cursor, VS Code, Codex CLI, Gemini CLI and Windsurf. You stay in control. Generating spends the credits in your wallet, and the agent is told to quote the price and ask you first. Posts are drafts until you send them, and nothing reaches a channel without the publish permission you grant on the consent screen, where you also pin the connection to one brand, cap monthly spend and choose when it expires. Generating and publishing need an active SocialFaktory plan. Not available through an agent yet: cloning a video from a link, and generating still images or carousels. Connecting a social channel is a browser sign-in and stays in the app. Docs: https://www.socialfaktory.com/docs/mcp
