## Install

This server runs on your machine as a child process of the client. You need the runtime its command uses, such as Node.js for npx, uv for uvx or Docker, plus any variables listed under Environment.

### Claude Code

`shell`

```
claude mcp add --scope project filesystem -- npx -y @modelcontextprotocol/server-filesystem /path/to/allowed/dir
```

### Cursor

`.cursor/mcp.json`

```
{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-filesystem",
        "/path/to/allowed/dir"
      ]
    }
  }
}
```

### Codex

`~/.codex/config.toml`

```
[mcp_servers.filesystem]
command = "npx"
args = ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/allowed/dir"]
```

[Config for other clients →](https://dotsagent.io/mcp/config#add=filesystem)

An agent can overwrite or move anything inside the directories you allow, so list only the ones it needs.
