14 tools. Find the one that does your job.
Every tool here shows the exact thing you give it and the real answer it returns, so you can tell whether it fits before you run it. Search by the problem you have, or narrow by what you are holding.
Nothing matches that combination. Loosen one filter or search for a plainer word.
Writing and AI tells
- Tells: Find the AI-writing tells in a draft, with their positions, and get a cleaned copy back.
Agent files and MCP servers
- Manifest cost: Measure what an MCP server's tool list costs in tokens each session and name the tools that cost most.
- Agent file lint: Lint a CLAUDE.md, AGENTS.md or MEMORY.md for duplicate rules, contradictions and lines past the 200-line cap.
- Tool lint: Lint an MCP server's tools for names the API rejects, missing descriptions and unlabelled destructive tools.
- Install snippets: Turn an MCP endpoint into ready-to-paste install snippets for five apps and confirm the server answers.
Crawlers, links and search
- AI crawlers: See which AI crawlers your robots.txt lets in or blocks, and get a draft llms.txt for the site.
- Page meta: Read one page the way a crawler and a link unfurler do and preview the share card it produces.
- Redirect tracer: Follow a URL hop by hop and flag redirect chains, loops, HTTPS downgrades and dropped query strings.
- Sitemap check: Read a site's sitemaps, count the URLs and fetch a sample to find the ones that are not a clean 200.
Security and secrets
- Security headers: Grade a URL's security headers and get the exact header to add for each gap.
- Env scrubber: Turn a .env into a safe .env.example and list the secrets it found by kind and line without echoing them.
- JWT decoder: Decode a JWT, see when it expires in plain words and catch alg none and sensitive claims.
Data and scheduling
- JSON to schema: Turn a JSON sample into a JSON Schema and a TypeScript type, with optional keys and formats inferred.
- Cron explainer: Explain a cron expression in plain English, list its next runs in UTC and warn where schedulers disagree.
