MCP Server: Let Claude, Cursor, and any AI agent manage social media via MagicSync

[modem-app]

Feature Request — MCP (Model Context Protocol) Server

Make MagicSync the first social media platform with a native MCP server. Any AI assistant (Claude Desktop, Cursor, Windsurf, Cline, OpenClaw, etc.) can directly schedule posts, check analytics, and manage businesses through MagicSync.

What is MCP?

The Model Context Protocol is the standard for AI tool ↔ application communication. An MCP server exposes tools, resources, and prompts that any compatible AI client can discover and use.

Architecture

Claude Desktop / Cursor / OpenClaw
    ↓ MCP Protocol (stdio or SSE)
MagicSync MCP Server (TypeScript)
    ↓ HTTP (authenticated)
MagicSync API (/api/public/v1/*)

Implementation: packages/mcp-server/

New package in the monorepo, published as @magicsync/mcp-server on npm.

Tools to expose:

Tool	Description
list_integrations	List all connected social media accounts
create_post	Create & schedule a post (content, media, platforms, date)
list_posts	List scheduled/published posts with filters
delete_post	Delete a scheduled post
get_analytics	Get post or platform analytics
upload_media	Upload image/video and get URL
list_businesses	List user's business profiles
get_business	Get business details + entity data
generate_content	AI-generate platform-optimized content
repurpose_content	Repurpose content across platforms
run_seo_audit	Run Apify-powered SEO audit
run_geo_audit	Run GEO audit
find_engagement_targets	Find social engagement opportunities

Resources to expose:

Resource	Description
magicsync://businesses	All business profiles
magicsync://integrations	Connected platform accounts
magicsync://posts/scheduled	Upcoming scheduled posts
magicsync://analytics/overview	Analytics summary

Prompts to expose:

Prompt	Description
schedule_campaign	Multi-platform campaign scheduling wizard
content_repurpose	Transform long content into platform posts
weekly_plan	Generate a week of content

Tech Stack

• @modelcontextprotocol/sdk — Official MCP TypeScript SDK
• Transport: stdio (for Claude Desktop) + SSE (for web clients)
• Auth: API key from MagicSync user settings

Config (for Claude Desktop claude_desktop_config.json):

{
  "mcpServers": {
    "magicsync": {
      "command": "npx",
      "args": ["@magicsync/mcp-server"],
      "env": { "MAGICSYNC_API_KEY": "your-key" }
    }
  }
}

Depends on

• Issue Public REST API for external integrations (n8n, Zapier, Make.com) #7 (Public REST API) — the MCP server calls the public API
• Issue Give user option to set the api key for the ai sdks in the user config page #1 (User settings / API key)

Why this is a game-changer

• First-mover advantage: No social media scheduler has an MCP server yet
• AI-native: Every AI coding tool user becomes a potential MagicSync user
• Zero-friction: npx @magicsync/mcp-server → instant social media superpowers for any AI
• Viral distribution: Gets listed on MCP server directories (mcp.so, smithery.ai, etc.)

building MCP servers for social media is a good call - we actually have our social posting pipeline automated through a skill system that uses the MCP protocol for browser automation. the key design decision is whether your MCP server handles auth internally or delegates to the client. for social platforms that require browser sessions (Reddit, Twitter, LinkedIn), we found it easier to use the browser automation MCP tool rather than trying to manage OAuth tokens directly. the API approach works better for platforms that support it natively.

here's how our social posting pipeline works with MCP browser automation for the platforms that need it: https://github.com/m13v/social-autoposter/blob/main/skill/SKILL.md - and the browser lock for handling concurrent agent access to the browser: https://github.com/m13v/browser-lock/blob/main/playwright-lock.sh
