    check domain health

    Example session with this skill installed

    Check the health for agensi.com. Make sure to look at the SSL certificate and mail security.

    • Read your context and instructions
    • Compiled the check domain health

    Audit for agensi.com:

    • SSL: Valid. Expires in 84 days (Low Risk).
    • DNS: Correctly configured.
    • HTTP: Reachable (200 OK).
    • Mail Security: SPF and DMARC records detected. Performance is healthy.
      No immediate actions required.

    About this skill

    The problem

    Manually checking SSL expiry, DNS records, and mail security protocols across multiple domains is tedious and error-prone. Most developers only realize a certificate has expired or a DMARC record is missing after a service outage or email deliverability crisis.

    What it does

    • Audits TLS/SSL certificate validity and calculates expiry countdowns.
    • Verifies DNS record configurations for correctness.
    • Checks HTTP reachability status to ensure web services are online.
    • Evaluates mail security posture by inspecting SPF and DMARC records.
    • Provides risk-level assessments for every automated check performed.

    Why this beats prompting it yourself

    A standard LLM cannot see the live state of the web and will hallucinate domain details. This skill connects your agent to actual networking tools, ensuring reports are based on real-time data rather than training data or guesses. It handles session-based caching and specific error states, providing a reliable diagnostic layer that broad prompts lack.

    Use cases

    • Perform a routine security audit on a list of client domains.
    • Troubleshoot "site down" or SSL handshake errors during deployment.
    • Verify mail server authentication settings (SPF/DMARC) for better deliverability.
    • Monitor certificate renewals by flagging upcoming expiries during development.

    Requires an active MCP server connection to the check_domain_health tool. Tool does not support internal network domains without public DNS resolution.

    How to use

    1. 1

      Connect your agent to the Agensi MCP

      Copy the prompt and paste it into Claude, ChatGPT, Cursor or any agent that supports MCP. It sets up the connection for you. Manual setup

    2. 2

      Sign in to Agensi

      Your agent shows a sign-in link. Sign in and click Allow.

    Frequently Asked Questions

    This skill uses the Model Context Protocol (MCP) to provide real-time networking data, allowing your AI agent to see live DNS records and SSL statuses rather than hallucinating outdated information.

    The skill audits TLS/SSL certificates, DNS record configurations, HTTP reachability, and critical email security protocols including SPF and DMARC.

    This skill is designed to work with any AI agent or platform that supports the Model Context Protocol (MCP), such as Claude Desktop or other compatible LLM interfaces.

    The skill returns a risk-level assessment for every automated check, categorizing issues based on urgency so your agent can prioritize critical security threats.

    Yes, it is designed for scale and can be prompted to perform routine audits across a provided list of multiple client domains in a single session.

    You receive the full MCP-integrated skill package ready for deployment, including lifetime updates and technical documentation for setup.
