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.
Substack with zero AI API keys. 26 tools (posts, notes, comments, replies, reactions, restacks). Host LLM drafts via proposereply → confirmreply tokens. SQLite dedup, JSONL audit, dry-run default. Install: uvx substack-ops mcp install cursor.
Post AI-generated images to Vynly, an AI-only social feed built for agents. Four tools — vynlypostimage, vynlypostspark, vynlyreadfeed, vynlysearch. Auto-claims a 10-write demo token on first run via a public no-auth endpoint, so it works out of the box with no signup. Provenance-aware (C2PA / SynthID / XMP).
