Side-by-side comparison of two Model Context Protocol servers — install paths, tools, quality signals, and directory engagement so you can pick the right one for Claude, Cursor, and other MCP clients.
Local LinkedIn MCP server for posting to LinkedIn from Claude. 9 tools — create/edit/delete posts (text, image, article), upload images, fetch profile, look up company pages, and check follower counts. Uses the official LinkedIn REST API with OAuth 2.0 (wmembersocial, OIDC).
MCP server for Substack — read posts, manage drafts, publish Notes, get comments, and upload images. Safe by design: cannot publish or delete posts.
