## Quality 81/100 (new)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise

- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-19 `decode_jwt` added
  - Decode a JWT's header and payload without verifying the signature (it never takes a secret). Returns the claims with iat, nbf and exp as ISO times, a plain-text expiresIn, issuer, subject and audience, and findings: alg none, HS* with a URL-like kid, missing or distant exp, expired, nbf or iat in the future, payload over 4 KB, sensitive field names, and jku or x5u pointing off-site.
- 2026-10-19 `check_sitemap` added
  - Check a site's sitemaps: discovers them from robots.txt, /sitemap.xml and /sitemap_index.xml, reads index files one level deep (20 children max), counts URLs per file and per host, summarises lastmod, and fetches a sample of URLs (HEAD, then GET) to count the ones that are not 200. Flags a missing sitemap, no robots.txt entry, over 50,000 URLs, other hosts, http URLs on https sites and missing lastmod.
- 2026-10-19 `trace_redirects` added
  - Trace a URL's redirect chain hop by hop (up to 10 hops, 8 s each) with status, location, timing and scheme per hop. Flags chains over two redirects, loops, HTTPS-to-HTTP downgrades, 302s used for www or https canonicalisation, dropped paths or query strings, cross-domain moves, meta-refresh or JS redirects on a 200, and a final page that is not 200.
- 2026-10-19 `scrub_env` added
  - Scrub a .env file into a safe .env.example: every value is blanked or replaced with a placeholder that keeps its shape (postgres://USER:PASSWORD@HOST/DB). Returns the example, the secrets found (AWS, GitHub, Stripe, Slack, Google, OpenAI, Anthropic, Resend, SendGrid, Twilio, Cloudflare, JWTs, private keys, database URLs, high-entropy strings) by key, kind and line with only the first 4 characters and the length, and findings for duplicate keys, non-UPPER_SNAKE names, unbalanced quotes, export prefixes and trailing spaces.
- 2026-10-19 `explain_cron` added
  - Explain a five-field cron expression in plain English, list the next runs in UTC, and warn about the cases Cloudflare Workers, GitHub Actions and crontab handle differently (nicknames, six fields, day-of-month plus day-of-week, sub-5-minute intervals, day 31).
- 2026-10-19 `json_to_schema` added
  - Turn a JSON sample (or an array of samples of the same shape) into a JSON Schema draft 2020-12 and a TypeScript type. Infers required vs optional keys across samples, nullable fields, integer vs number, date/email/uri/uuid formats, and small enums. Use it to draft an MCP tool inputSchema from an example payload.
- 2026-10-19 `check_page_meta` added
  - Fetch a URL and report what crawlers and link unfurlers see: title and meta description with lengths, canonical, lang, viewport, robots meta, h1s, Open Graph and Twitter card tags, favicon, JSON-LD types, the resulting preview card, and findings for anything missing or too long.
- 2026-10-19 `check_headers` added
  - Fetch a URL once and grade its response headers: HSTS, Content-Security-Policy, X-Content-Type-Options, frame control, Referrer-Policy, Permissions-Policy, Cache-Control, cookie Secure/HttpOnly/SameSite flags, and server version leaks. Returns a grade, a score and the exact header to add for each gap.

## Packages

_none_

## Tools (13)

- `check_ai_crawlers`: Read a site's robots.txt and report which AI crawlers (GPTBot, ClaudeBot, Google-Extended, PerplexityBot, CCBot, Bytespider and more) are allowed, blocked or partially blocked; check for llms.txt and draft one from the site's metadata and sitemap.
- `check_headers`: Fetch a URL once and grade its response headers: HSTS, Content-Security-Policy, X-Content-Type-Options, frame control, Referrer-Policy, Permissions-Policy, Cache-Control, cookie Secure/HttpOnly/SameSite flags, and server version leaks. Returns a grade, a score and the exact header to add for each gap.

- `check_sitemap`: Check a site's sitemaps: discovers them from robots.txt, /sitemap.xml and /sitemap_index.xml, reads index files one level deep (20 children max), counts URLs per file and per host, summarises lastmod, and fetches a sample of URLs (HEAD, then GET) to count the ones that are not 200. Flags a missing sitemap, no robots.txt entry, over 50,000 URLs, other hosts, http URLs on https sites and missing lastmod.
- `check_tells`: Check text for AI-writing tells (em-dashes, 'not just X but Y', rule-of-three lists, stock vocabulary like delve or seamlessly, hedge words, smart quotes, hidden Unicode) and return a score, each tell with its position, and a cleaned copy. Run it on anything you are about to publish on a human's behalf.
- `decode_jwt`: Decode a JWT's header and payload without verifying the signature (it never takes a secret). Returns the claims with iat, nbf and exp as ISO times, a plain-text expiresIn, issuer, subject and audience, and findings: alg none, HS* with a URL-like kid, missing or distant exp, expired, nbf or iat in the future, payload over 4 KB, sensitive field names, and jku or x5u pointing off-site.

- `lint_agent_md`: Lint a CLAUDE.md, AGENTS.md or MEMORY.md: line count against Claude Code's 200-line memory index cap, estimated tokens, duplicate lines, contradicting rules, leftover TODO markers, hidden characters, empty headings.
- `manifest_cost`: Estimate what an MCP server's tools/list costs in tokens on every session start, per tool, with the three most expensive tools and flags for oversized descriptions, base64 blobs and echoed schemas. Pass a live Streamable HTTP endpoint or a tools array.
- `mcp_install_snippets`: Generate install snippets for an MCP endpoint (Claude Code, Claude Desktop, Cursor, Codex, VS Code, curl) and probe the endpoint once to confirm it answers initialize and tools/list.
- `scrub_env`: Scrub a .env file into a safe .env.example: every value is blanked or replaced with a placeholder that keeps its shape (postgres://USER:PASSWORD@HOST/DB). Returns the example, the secrets found (AWS, GitHub, Stripe, Slack, Google, OpenAI, Anthropic, Resend, SendGrid, Twilio, Cloudflare, JWTs, private keys, database URLs, high-entropy strings) by key, kind and line with only the first 4 characters and the length, and findings for duplicate keys, non-UPPER_SNAKE names, unbalanced quotes, export prefixes and trailing spaces.
