Filesystem vs FreeRDC
A side-by-side look at the Filesystem and FreeRDC 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 FreeRDC for file systems over a hosted endpoint. You can also run both side by side in one mcpServers block.

Frequently asked questions
Filesystem is categorized under File Systems and uses a local stdio subprocess. FreeRDC belongs to File Systems and uses a remote HTTP/SSE transport. Pick Filesystem for file systems work and FreeRDC for file systems.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Filesystem is listed as free. Auth: no auth required. FreeRDC has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add filesystem and freerdc as separate keys in the same mcpServers object, and your assistant will call tools from either one.
