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.
Full Signal messenger MCP server and CLI. Send/receive messages, manage groups and contacts, search history, handle attachments and reactions. Runs locally via signal-cli — no third-party servers.
All-in-one Feishu/Lark MCP server (84 tools). Send messages as the actual user (not bot), plus full official-API coverage of docs, bitable, wiki, drive, calendar, tasks, OKR. Cookie + OAuth UAT + app-credential auth.
