Post to Social Media from Claude, ChatGPT, and Any AI Agent
Socialync runs a full MCP (Model Context Protocol) server, so any AI assistant that speaks MCP can draft, schedule, and publish content to your TikTok, Instagram, YouTube, X, LinkedIn, Facebook, Threads, and Bluesky accounts — from the conversation you are already having.
Included in Business — $40/mo per profile · No per-task fees
Your AI assistant. Your social accounts. Connected.
Most social media tools force you to log in, click around, paste your caption six times, and pick a time. With MCP, you just tell your AI what you want — and it handles the rest.
Without MCP
- • Open the dashboard
- • Paste content into 8 different fields
- • Adjust each caption for each platform
- • Pick a schedule time
- • Click publish, click confirm, repeat
With Socialync MCP
In Claude:
“Take this video transcript, write a TikTok hook, an Instagram caption with 5 hashtags, and a LinkedIn version that ends with a question. Schedule all three for Thursday at 9am.”Done.
How It Works
Generate an MCP Key
In Socialync settings, generate an MCP key for the profile you want your AI to post from. Keys are scoped per profile and revocable any time.
Connect Your AI
Paste the key into Claude Desktop, ChatGPT, Cursor, or any MCP client. Socialync exposes tools for drafting, scheduling, and listing scheduled posts.
Post in Plain English
Tell your AI what to do. Drafts route to your approval queue by default — flip the switch to direct-publish when you trust the workflow.
What You Can Build
Repurpose long-form into 8 posts
Drop a podcast transcript or YouTube video into Claude. It generates platform-tuned captions for every channel and queues them in your drafts.
Reply to your own posts in bulk
Have your AI scan your scheduled queue and add the right opening comment, hashtag set, or pinned reply per platform — all before anything goes live.
Brand-voice automation
Give your AI a system prompt with your brand voice, audience, and pillars. Every draft it writes is on-brand without a human touching the caption.
Custom agents for your team
Build a custom GPT or Claude agent for your social manager that already knows your tone, your platforms, and your approval flow. Onboarding becomes a paste.
Trigger from anything
Wire up a Claude Agent SDK script that watches your CMS, your YouTube uploads, or your podcast RSS — and drafts social posts the moment something publishes.
Approval workflows for clients
Agencies: let the AI generate, route to your client for approval through Socialync drafts, and publish on green-light. Zero double-entry.
Works with Every MCP Client
If it speaks Model Context Protocol, it works with Socialync.
FAQ
What is an MCP server for social media?
MCP (Model Context Protocol) is the open standard for connecting AI assistants to external tools. Socialync runs an MCP server that lets any MCP-compatible AI — Claude, ChatGPT, Cursor, custom agents — draft, schedule, and post content to your connected social accounts on TikTok, Instagram, YouTube, X, LinkedIn, Facebook, Threads, and Bluesky.
Which AI assistants can post to social media through Socialync?
Any MCP-compatible client. That includes Claude (Desktop and the API), ChatGPT custom GPTs via the connector, Cursor, Continue, Zed, and any agent built on the Anthropic Agent SDK or OpenAI MCP client. If your tool speaks MCP, it works with Socialync.
Is the AI posting directly to my account, or going through review?
You choose. By default, AI-generated posts land in a drafts queue you review and approve before publishing. You can flip on direct-publish per profile if you trust the agent — useful for branded automations and content workflows.
How is this different from Zapier or n8n?
Zapier and n8n are deterministic workflow tools — they trigger on rules. MCP is conversational: your AI assistant decides what to post based on context you give it ("turn this transcript into a Twitter thread and an Instagram caption, then schedule both for Thursday at 9am"). It is also free with a Business plan, where Zapier charges per task.
Which plan includes MCP access?
MCP access is part of the Business plan ($40/month per profile). It includes one MCP key per profile, plus everything in Premium — unlimited posts, all 8 platforms, AI captions, transcript analyzer, and team collaborators.
Is my account safe? What can the AI actually do?
MCP keys are scoped per profile and revocable at any time from your Socialync settings. The AI can only do what your plan permits — draft, schedule, post, list scheduled content. It cannot change billing, delete your account, or access connected platforms outside the API surface Socialync exposes.
