How this service works
A hosted MCP server exposing utility tools any AI agent can call over HTTP — page-to-markdown, SEO audits, robots/sitemap checks, and more.
Output
Returns a performance report for the given URL, including metrics such as page load time, performance score, and other diagnostics that indicate how well the page is performing.
Example use cases
Pre-launch site speed audit
“Before we go live, can you check the performance of https://mystore.com and let me know if the page is fast enough or if there are any issues I should fix?”
Competitor benchmarking
“I want to know how https://competitor.com performs — can you measure their page speed and give me the key metrics?”
Ongoing blog post performance check
“Can you check the performance of https://myblog.com/latest-post and tell me if it loads quickly on its own?”
Technical details
Endpoint
POSThttps://papacasper.com/mcp/pay/page_performance_checkWhen to prefer
Choose this endpoint when you need a quick, pay-per-call performance measurement of a specific webpage without setting up your own infrastructure. Ideal for one-off checks, automated agent workflows, or when you need performance data integrated directly into an AI pipeline via MCP over HTTP.
Side effects
- Invalid or unreachable URL — endpoint may return an error or empty result
- URL behind authentication or firewall — page may not load correctly for measurement
- Timeout if the target page is extremely slow to respond
- Malformed URL input causing validation failure
