[mcp-stress-test] MCP Server Configuration Requirements - Browser, Filesystem, Kubernetes

[github-actions]

MCP Server Configuration Issues Detected - 2026-02-04

The nightly stress test detected 4 servers that require additional environment configuration beyond authentication.

Test Summary

• Test Session: stress-test-20260204-180602
• Test Date: 2026-02-04T18:06:02Z
• Total Configuration Issues: 4

Servers Requiring Configuration

1. Filesystem - Path Configuration Required

Container: mcp/filesystem

Issue Type: Configuration Required

Description:
The filesystem MCP server requires explicit path configuration to define which directories can be accessed. This is a security feature to prevent unauthorized file access.

Suggested Configuration:

{
  "filesystem": {
    "type": "stdio",
    "container": "mcp/filesystem",
    "env": {
      "ALLOWED_PATHS": "/tmp,/workspace"
    }
  }
}

Suggested Investigation:

• Define safe sandbox paths for file operations
• Document allowed paths in configuration
• Test filesystem operations with configured paths

2. Puppeteer - Browser Environment Required

Container: mcp/puppeteer

Issue Type: Configuration Required

Description:
The Puppeteer MCP server requires a browser/display environment to run headless Chrome. The current test environment doesn't have the necessary dependencies.

Suggested Configuration:

{
  "puppeteer": {
    "type": "stdio",
    "container": "mcp/puppeteer",
    "env": {
      "PUPPETEER_SKIP_CHROMIUM_DOWNLOAD": "false"
    }
  }
}

Suggested Investigation:

• Set up headless browser environment
• Install Chromium dependencies
• Test browser automation capabilities
• Consider using official Puppeteer Docker image

---

3. Playwright - Browser Environment Required

Container: mcp/playwright

Issue Type: Configuration Required

Description:
The Playwright MCP server requires a browser/display environment similar to Puppeteer. Multiple browser engines (Chromium, Firefox, WebKit) may need to be configured.

Suggested Configuration:

{
  "playwright": {
    "type": "stdio",
    "container": "mcp/playwright",
    "env": {
      "PLAYWRIGHT_BROWSERS_PATH": "/ms-playwright"
    }
  }
}

Suggested Investigation:

• Set up headless browser environment
• Install browser dependencies
• Test with Playwright Docker image
• Configure browser selection preferences

---

4. Kubernetes - Cluster Configuration Required

Container: mcp/kubernetes

Issue Type: Configuration Required

Description:
The Kubernetes MCP server requires access to a Kubernetes cluster. This includes kubeconfig, cluster credentials, and network access.

Suggested Configuration:

{
  "kubernetes": {
    "type": "stdio",
    "container": "mcp/kubernetes",
    "env": {
      "KUBECONFIG": "${KUBECONFIG}",
      "KUBERNETES_CLUSTER_URL": "${KUBERNETES_CLUSTER_URL}"
    }
  }
}

Suggested Investigation:

• Set up test Kubernetes cluster (kind, minikube, or k3s)
• Configure kubeconfig access
• Test basic kubectl operations
• Consider cluster isolation for testing

---

Test Configuration

The test used the following configuration:

• Startup Timeout: 60s
• Tool Timeout: 30s
• Port: 3000

Next Steps

1. Prioritize configuration of browser environments (Puppeteer/Playwright) as they're commonly used
2. Set up filesystem with appropriate sandbox paths
3. Configure Kubernetes access for container orchestration testing
4. Re-run stress test after configurations are in place

Success Metrics

When properly configured, we expect:

• Filesystem: Successful file listing and read operations
• Puppeteer/Playwright: Successful browser navigation and screenshot capture
• Kubernetes: Successful cluster queries and resource listing
