MCP Service Description: Domain DA - PA Checker

1. MCP Service Description

Domain DA - PA Checker is a standardized MCP (Model Context Protocol) service designed to help users evaluate the online authority and credibility of domains and web pages. It simplifies access to critical SEO and digital marketing metrics, enabling data-driven decisions to enhance online visibility, partnership strategies, and content performance.

At its core, the service provides real-time, actionable insights into key metrics that define a domain or page’s influence: Domain Authority (DA), Page Authority (PA), external link quality, and spam risk. By aggregating trusted data, it eliminates the need for manual research or disjointed tools, offering a single, consistent source of truth for users across industries. Its value lies in empowering SEO professionals, marketers, and website owners to quickly assess digital assets—whether optimizing their own sites, vetting partner domains, or analyzing competitors—without technical complexity.

2. Tool Name and Function

The service includes one primary MCP tool: getDaPa.
Function: getDaPa retrieves five critical metrics for any given domain or web page:

  • Domain Authority (DA): A score predicting a domain’s ability to rank in search engines.
  • Page Authority (PA): A score predicting a specific page’s ranking potential.
  • External nofollow urls to url: The number of external links pointing to the URL that use a "nofollow" tag (indicating limited ranking value).
  • External urls to url: The total number of external links pointing to the URL.
  • Spam Score: A risk indicator reflecting how likely the URL is to be flagged as low-quality or spammy by search engines.

3. Tool Introduction

getDaPa is built for simplicity and impact, enabling users to complete key tasks in seconds. Here’s how it works in practice:

  • Assess authority quickly: Users input a domain or page URL, and getDaPa returns DA and PA scores—benchmarks that help compare a site’s influence against competitors or industry standards. For example, a high DA score signals strong search engine trust, making it a priority for backlink outreach.
  • Analyze link quality: The tool breaks down external links into "nofollow" and total counts, helping users identify which URLs drive meaningful ranking value. A page with many high-quality, dofollow links (low nofollow ratio) is more likely to rank well.
  • Mitigate spam risks: The Spam Score alerts users to potential red flags, such as low-quality backlinks or suspicious content. This helps avoid penalties from search engines and ensures digital assets remain credible.

No technical expertise is required—getDaPa delivers clear, digestible metrics that translate directly into action, from optimizing content to rejecting high-risk partnerships.

4. Application Scenarios and Integration Advantages

Application Scenarios

  • SEO Monitoring: Track DA/PA changes over time to measure the impact of optimization efforts (e.g., content updates, backlink campaigns).
  • Partnership Vetting: Evaluate potential collaborators’ domains (e.g., guest post hosts) to ensure they have high authority and low spam scores, protecting your brand’s credibility.
  • Page Optimization: Use PA and external link data to prioritize high-potential pages for updates, focusing on those with strong ranking potential but low external link counts.
  • Domain Selection: Compare DA scores of available domains when launching a new site, choosing one with existing authority to accelerate search visibility.

Integration Advantages

As an MCP-compliant service, Domain DA - PA Checker offers seamless integration into existing workflows and systems. MCP’s standardized protocol eliminates the need for custom API development, reducing integration time and costs. It works across platforms (e.g., SEO tools, marketing dashboards, CMS systems) and ensures consistent data formatting, so users can aggregate insights with other MCP services (e.g., keyword trackers, traffic analyzers) without manual adjustments. This interoperability makes it a flexible, future-proof solution for teams seeking to unify their digital tools stack.

Summary: Domain DA - PA Checker simplifies access to critical authority metrics, empowering users to make smarter, faster decisions. With getDaPa and MCP’s standardized integration, it bridges the gap between data and action—all in a user-friendly, scalable package.
