 ## Accessing other workloads on the same container network
 
+ToolHive allows you to configure both outbound and inbound network access for
+MCP servers. This is commonly needed when your MCP server needs to communicate
+with databases, APIs, or other services that are running on your local host
+during development, or when other containers need to communicate with your MCP
+server.
+
+### Outbound access: MCP server to other workloads

 To allow an MCP server to access other workloads on the same network, you need
-to configure network isolation to include the appropriate hostnames and ports.

 access services on the host. `host.docker.internal` is a special hostname

+### Inbound access: Other containers to MCP server
+
+By default, the ingress proxy only allows traffic from the container's own
+hostname, `localhost`, and `127.0.0.1`. If you need to allow other containers or
+workloads to communicate with your MCP server, configure the
+`network.inbound.allow_host` setting in your permission profile.
+
+This is useful when:
+
+- Other containers need to call your MCP server's API
+- You're running multiple services that need to communicate with each other
+- You need to allow traffic from specific internal hostnames or domains
+
+Create a permission profile that allows specific inbound hostnames:
+
+```json title="inbound-access-profile.json"
+{
+  "network": {
+    "inbound": {
+      "allow_host": ["host.docker.internal", "localhost"]
+    }
+  }

+```bash
+thv run --isolate-network --permission-profile ./inbound-access-profile.json <SERVER>

+If no `network.inbound` configuration is specified, the ingress proxy uses the
+default behavior of allowing traffic only from the container's own hostname,
+`localhost`, and `127.0.0.1`.
