Posty is a social media management MCP server for creating, scheduling, reviewing, and managing content across multiple social channels and workspaces. It lets AI assistants discover connected accounts, create and edit posts, schedule publishing, submit content for approval, approve or reject posts, add comments, and view upcoming scheduled content.
Built for teams, agencies, and creators, Posty makes it possible to manage real social media workflows directly from MCP-compatible AI clients.

Scored across 21 tools
Most tools are clearly distinct by resource and HTTP method, but act_on_post overlaps with patch_posts_id for status changes, and comment-related tools lack a single-comment fetch, which could cause confusion. Overall, the boundary between action-oriented and generic update is the main ambiguity.
The naming follows a consistent verb_resource_path pattern with underscores for all HTTP-based tools, but act_on_post deviates from this convention by using a descriptive verb phrase instead of a resource path. This is a minor inconsistency in an otherwise predictable naming scheme.
With 21 tools, the server is on the heavier side for a content management system, but each tool corresponds to a specific endpoint or action, making it justifiable. The count is borderline high, but the domain (posts, media, comments, channels, workspaces) warrants many operations.
The tool surface covers most CRUD operations for posts, media, and comments, but lacks some expected operations like updating comments, fetching a single comment, or updating media metadata. The absence of workspace management beyond listing also creates a gap in the lifecycle coverage.
