Example Command:

Usage

UI

Select the fetch MCP server in the ToolHive registry. No additional configuration is required to run it.

By default, it can access any website. To restrict its network access, enable network isolation and enter the allowed hosts and ports.

CLI

Run with the default configuration:

thv run fetch

To control which website resources the server can access, create a custom permission profile:

fetch-profile.json

{
  "network": {
    "outbound": {
      "insecure_allow_all": false,
      "allow_host": [
        "host.docker.internal",
        "intranet.example.com",
        ".googleapis.com"
      ],
      "allow_port": [443]
    }
  }
}

Then run the server with the profile and enable network isolation:

thv run --isolate-network --permission-profile fetch-profile.json fetch

Kubernetes

Create a Kubernetes manifest to deploy the Fetch MCP server:

fetch.yaml

apiVersion: toolhive.stacklok.dev/v1alpha1
kind: MCPServer
metadata:
  name: fetch
  namespace: toolhive-system
spec:
  image: ghcr.io/stackloklabs/gofetch/server:0.0.5
  transport: streamable-http
  targetPort: 8080
  port: 8080
  permissionProfile:
    type: builtin
    name: network

Apply the manifest to your Kubernetes cluster:

kubectl apply -f fetch.yaml

Sample prompts

Here are some sample prompts you can use to interact with the Fetch MCP server:

• "Fetch the latest news from https://news.ycombinator.com"
• "Get the current weather for https://weather.com"
• "Retrieve the latest blog posts from https://example.com/blog"

Recommended practices

• Use network isolation to restrict the server's outbound network access to the specific hosts and ports required for your use case.
• Enable telemetry to monitor tool usage including URL access for security and auditing purposes.
