MCP Server Filesystem is completely free with all essential features included. No paid tiers offered, making it perfect for budget-conscious users.
Specify allowed directories as command-line arguments when starting the server: 'mcp-server-filesystem /path/to/dir1 /path/to/dir2'. If your MCP client supports Roots, it can dynamically update allowed directories at runtime without restarting.
It is intended for MCP-compliant clients. Clients that support the Roots protocol can provide dynamic directory access control.
If the server starts without command-line arguments AND the connecting client doesn't support Roots (or provides empty roots), the server will throw an error during initialization. At least one access method must provide allowed directories.
The supplied metadata does not provide enough detail to make a reliable claim about binary-file handling. Verify the current repository implementation before relying on a specific encoding, MIME type, or transfer behavior.
No. This listing refers to the implementation in the modelcontextprotocol organization repository. Other similarly named filesystem servers may be separate community implementations.
It's completely free — no credit card required.
