## Description

This MCP gives your agent the ability to audit web hosting sources. You can check any URL against a massive database of green providers to see if it runs on renewable energy. Whether you're researching carbon footprints for a new product or just vetting an eco-friendly vendor, this tool verifies sustainability claims instantly. Instead of guessing about a site's power source, your agent gives you hard data. When connected through Vinkius, you treat the entire catalog like one resource—you don’t have to switch tools; you just ask for the green web check and get the answer right away.

## Capabilities

### Check Site Green Status
Verifies if a specific website URL is hosted on a platform that uses renewable energy.

### Get Provider Details
Identifies the hosting company and pulls their official sustainability records for review.

### Audit Multiple Domains
Runs green checks across a list of domains, giving you a profile of your digital supply chain's carbon footprint.

## Use Cases

### Vetting a New Vendor
A procurement team needs to select a new cloud vendor. Instead of trusting their marketing claims, they ask their agent to use the tool to run `check_green_hosting` on the potential vendor’s main domain. The agent confirms if the required renewable energy credentials are present before signing any contract.

### Compliance Check
A sustainability officer must audit a company's portfolio of public-facing sites for ESG reporting. They pass a list of ten URLs to their agent and run the multi-domain check, instantly profiling the group’s overall energy risk.

### Researcher Deep Dive
A digital ethics researcher is tracking how many major websites are moving toward green hosting. They repeatedly use `check_green_hosting` on key industry sites to build a real-time dataset of the web's energy transition.

## Benefits

- You move beyond vague sustainability reports. With this MCP, you get hard data confirming if a site's infrastructure runs on renewable sources.
- Instead of manual research across multiple databases, your agent handles the check instantly. You can verify dozens of domains in one conversation turn.
- It saves time for compliance teams. Auditing digital assets—especially when vetting third-party vendors—used to be a slow process; now it’s an immediate query.
- You can profile an entire digital supply chain's carbon footprint using the multiple domain check capability.
- The tool integrates directly into your workflow, letting you run sustainability checks without leaving your main development environment.

## Frequently Asked Questions

**Is Google.com hosted on green energy?**
Yes! Google is a registered green hosting provider in the database. You can use the `check_green_hosting` tool to verify the status of any of its domains.

**What does it mean if a site is not green?**
It means the hosting provider is either using conventional fossil-fuel-based energy or has not yet registered their renewable energy usage with the Green Web Foundation.

**Can I check multiple domains in a single session?**
Yes. You can provide a list of domains to your AI agent, and it will call the `check_green_hosting` tool for each one, providing a summarized sustainability report.

**How do I use `check_green_hosting` without needing an API key?**
You don't need one. The service is publicly accessible, meaning your agent simply connects to the MCP and runs the tool directly. You can start checking sustainability data immediately.

**What happens if I run `check_green_hosting` on a domain that doesn't exist?**
The system will return an error indicating invalid input, so your agent knows exactly what went wrong. It prevents vague failures and provides clear feedback when the URL is unreachable.

**Are there rate limits when running `check_green_hosting` for high volume audits?**
Yes, usage has defined quotas to prevent abuse. If you plan on large-scale batch auditing, we recommend reviewing the full documentation or structuring your requests into timed batches.

**What data sources does `check_green_hosting` use to verify green energy status?**
The tool draws from an extensive, continually updated open database tracking hosting infrastructure. The results confirm the provider's registered commitment and reported usage of renewable power.

**Can `check_green_hosting` detect if a website switched its hosting providers?**
It checks against the most current records available in the green web database. If a provider changes infrastructure, the tool reports based on the latest verified sustainability data.
