How to use ErgoKit
Use ErgoKit to check public websites, inspect search and AI-readiness signals, and run everyday developer utilities.
Format JSON, decode JWTs, convert Base64, generate hashes, UUIDs, QR codes, UTM URLs, and more.
Compatible MCP clients can call selected read-only ErgoKit diagnostics for public URLs and domains.
Web Tools
Most users should start from the web app. Search for a tool on the homepage, open the tool page, enter a public URL or local input, and review the result summary, details, issues, and recommendations.
Choose A Tool
- AI visibility
- Use GEO Score Checker, Meta Tag / OG Preview, Schema Validator, Robots.txt Tester, and Sitemap Checker.
- Technical SEO
- Use HTTP Status Checker, Redirect Chain Checker, Sitemap Checker, Meta Tag / OG Preview, and Schema Validator.
- Security
- Use Security Headers Checker, CORS Tester, JWT Decoder, and Hash Generator.
- Developer work
- Use JSON Formatter, Base64 Tool, UUID Generator, Timestamp Converter, URL Encoder/Decoder, and Cron Generator.
- Marketing
- Use UTM Builder, QR Code Generator, URL Encoder/Decoder, and Meta Tag / OG Preview.
MCP For AI Clients
MCP is optional. Use it when an AI client, agent, or automation needs to call ErgoKit tools directly. For normal use, the website is the easiest interface.

Privacy And Safety
- Local utilities run in your browser. Do not paste secrets unless you are comfortable handling them locally.
- Public URL checks fetch public pages transiently and show metadata, headers, timing, issues, and recommendations.
- ErgoKit does not show full response bodies in server-side diagnostic results.
- Private, local, internal, and reserved network targets are blocked.
- MCP tools are read-only and rate-limited.
Public Index Files
These are mainly for search engines, AI crawlers, and integrations. Most users do not need them directly.
