Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
Once Atlas Social MCP is connected, these are the calls the assistant has available:
post_now — Post immediately. AI adapts content per platformschedule_post — Schedule for future date/timegenerate_calendar — 30-day content calendar with AIget_analytics — Performance metrics across platformsget_recent_posts — Recent post history and statuslist_accounts — Connected social accountsKey — RequiredZERNIO_API_KEY — YesANTHROPIC_API_KEY — OptionalYou will need 2 environment variables: ZERNIO_API_KEY, ANTHROPIC_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.
Among the planning and project tracking options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Atlas Social MCP's toolset — post_now, schedule_post, generate_calendar and 6 more — is a fair guide to whether it matches your workflow. It is maintained by chrismole310; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
