A side-by-side look at the Ellmos Clatcher MCP and Filesystem MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Ellmos Clatcher MCP for file systems work as a local process; choose Filesystem for file systems as a local process. You can also run both side by side in one mcpServers block.
fix_json, fix_encoding, fix_umlauts.create_entities, create_relations, add_observations.Rows where the two servers differ are marked.
