Social0 MCP Server

Post and schedule across 9 social platforms from Claude, Cursor, or ChatGPT. Exposed over MCP by the social0 mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

Post to Instagram, TikTok, YouTube, X, LinkedIn, Facebook, Pinterest, Threads, and Bluesky from Claude, Cursor, ChatGPT, and other AI apps — in plain English.

Adding it to your client

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

Its toolset

Everything the assistant can do here goes through one of these:

• Host — Where
• Cursor — Settings → MCP / .cursor/mcp.json

Configuration

You will need one environment variable: SOCIAL0_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Caveats

• Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the social0 mcp server does with a few real requests.

When to reach for it

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Social0's toolset — Host, Cursor — is a fair guide to whether it matches your workflow. It is maintained by Abhishek-B-R; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
