Filesystem

Install Filesystem

claude mcp add filesystem -- npx -y @modelcontextprotocol/server-filesystem

Use Filesystem with Claude Code

Once the server is on your machine, register it with Claude Code so the agent can call it like any other tool. The general pattern is:

claude mcp add filesystem -- <install-command>

After it's registered, run claude and ask anything that requires Filesystem. Claude Code will negotiate the MCP handshake and surface the server's tools, prompts, and resources to the model automatically. See our Claude Code MCP guide for environment variables, scope flags, and credential handling.

What this server is for

Filesystem sits in the reference servers category. It's officially maintained, which means breaking changes ship through proper releases and there's a real support channel. The full description from the source list:

Secure file operations with configurable access controls

FAQ

Is Filesystem free?

Yes — every MCP server in the ClawHire directory is open-source or freely available. Some servers proxy to paid APIs (you supply your own keys), but the server itself is free.

Does it work with Claude Desktop / Cursor / Windsurf?

If a client speaks the Model Context Protocol, it can use this server. The transport (stdio vs SSE vs HTTP) needs to match what the client supports, but the server itself is client-agnostic.
