Publish to 13+ social media platforms from any AI agent via MCP.
Postbolt MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. Publish to 13+ social media platforms from any AI agent via MCP.
Once Postbolt is connected, these are the calls the assistant has available:
publish_post — The publish_post tool exposed by this serverschedule_post — The schedule_post tool exposed by this serverlist_posts — The list_posts tool exposed by this serverget_post — Get detailed info about a post including per-platform resultsupdate_post — The update_post tool exposed by this servercancel_post — The cancel_post tool exposed by this serverupload_media — The upload_media tool exposed by this serverSetup 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.
You will need one environment variable: POSTBOLT_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 developer tooling 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. Postbolt's toolset — publish_post, schedule_post, list_posts and 4 more — is a fair guide to whether it matches your workflow. It is maintained by Whitemarmot; 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.
