Filesystem vs Silica Core
A side-by-side look at the Filesystem and Silica Core MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Filesystem for file systems work as a local process; choose Silica Core for file systems as a local process. You can also run both side by side in one mcpServers block.
