+
+Supported agents connect to a single MCP gateway endpoint for the sandbox. The
+gateway runs on the host side of the sandbox boundary and brokers access to
+registered MCP servers.
+
+Registered MCP servers can be remote endpoints, or they can be local stdio
+servers launched on the host. Local stdio servers don't run inside the sandbox
+VM. If a local stdio server is packaged as an OCI image, or if you register an
+explicit `docker` command, it uses Docker on the host.

+keywords: docker sandboxes, filesystem access, filesystem rules, workspace mount, organization policy, governance
+---
+
+Filesystem access policies control which host paths a sandbox can mount as a
+workspace. Each policy contains one or more rules that restrict sandbox
+workspaces to approved directories.
+
+Filesystem access is managed with [organization policies](organization.md). When
+organization governance is active, filesystem rules replace local behavior for
+workspace mounts.
+
+## Rule syntax
+
+Filesystem rules use the actions `read` and `write`. Resources are host path
+patterns.
+
+A writable workspace mount must be allowed by both a `read` rule and a `write`
+rule. A read-only workspace needs only `read`.
+
+Examples:
+
+- `~/**`
+- `/data/project/**`
+- `C:\data\project\**`
+- `\\wsl.localhost\<distro>\data\project\**`
+
+Use `**` to match a directory tree recursively. A single `*` matches only one
+path segment. For exact path matching behavior across macOS, Linux, Windows,
+and WSL, see [Filesystem rules](../concepts.md#filesystem-rules).
+
+## Organization filesystem rules
+
+Organization filesystem rules belong to policies that can apply to the whole
+organization or to selected teams. For setup steps and team scoping, see
+[Organization policies](organization.md).
+
+Filesystem policy is checked when a workspace is mounted, which happens when a
+sandbox is created. To apply a filesystem policy change to a running workflow,
+remove the sandbox and create a new one.
+
+## Troubleshooting
+
+### Sandbox cannot mount workspace
+
+If a sandbox fails to mount with a `mount policy denied` error, verify that the
+filesystem allow rule uses `**` rather than `*`. A single `*` doesn't match
+across directory separators.
