Nothing serious here today

Today is the operative word: we check Socialync every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Socialync — questions

Answers built from our own checks of this server.

Why is there no tool list for Socialync?
The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.
Is Socialync working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 184 of 184 checks got a reply (100.0%), average response time 297 ms. The bar chart above shows every period we have measured.
How do I connect Socialync?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.
How do you sign in to Socialync?
No API key is involved. Socialync answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.
How fast is Socialync?
It answers our handshake in 297 ms on average, which is faster than 50% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Socialync open source?
Yes — it is published under the MIT licence and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
