Show HN: Bulk URL Checker – check 75k URLs from any LLM via MCP (bulkurlchecker.com)

A new tool called Bulk URL Checker has been announced, allowing users to validate up to 75,000 URLs in a single batch by simply uploading a CSV file. This cloud-based solution handles URL status codes, redirects, and response times without any software installation or setup required. Users receive emails once their URL checks are complete and can export results in CSV or JSON format. The service offers 300 free URL checks to new accounts and employs intelligent proxy rotation and retry logic to manage rate limit issues automatically. This tool is significant for the AI/ML community as it integrates seamlessly with popular language models like Claude and ChatGPT, allowing for native link auditing capabilities. Instead of traditional desktop tools that often face IP blocks and require manual oversight, Bulk URL Checker operates unattended, ensuring reliable performance. With a straightforward credit system—where 1 credit equals 1 URL check—users can access a powerful resource tailored for high volume audits without the burden of subscriptions or expiration. This innovation stands out against competitors like Screaming Frog by offering cloud-based convenience, scalability, and comprehensive analytics at a competitive price point.
