## Quality 82/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- pass `tools.annotations`: 8 of 8 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: credits (idempotentHint); preflight (idempotentHint); read (idempotentHint); …
- pass `tools.token_cost`: about 1,307 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

### stability: 83 (weight 15)

- warn `stability.changes`: 8 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name
- pass `stability.new_links`: no tool change named a new site

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 8, about 1,307 tokens to load them all
- tool set hash: cd67a80c1adfb89a2a2f15aab8c3a404
- tools last changed: 2026-10-29T09:40:56.125Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.bastionhelix/agent-lens.svg)](https://protogrid.dev/servers/com.bastionhelix/agent-lens)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (8)

- `actions`: Returns the forms (with every field, its label and whether it is required), buttons and links on a page, each with a CSS selector an automation tool can use. Uses the rendered page when the HTML alone has none. Charged only on success. Price: US$0.004 per successful call (API key credits or x402).
- `credits`: Free. Credits remaining on the API key sent in the Authorization header (1 credit = US$0.001).
- `delta`: For pages an agent checks again and again. The first call returns the page as sections plus a fingerprint; send that fingerprint back as "previous" next time and get only the sections that changed (and the headings of removed ones), or changed:false. Uses HTTP ETag/Last-Modified when the site supports them. Nothing is stored on our side: the fingerprint lives with the agent. Saves tokens on every re-check. Charged only on success. Price: US$0.001 per successful call (API key credits or x402).
- `extract`: No AI model involved: returns the structured data the page already publishes — JSON-LD / schema.org objects (products, articles, events, organisations, breadcrumbs), prices and offers, meta and Open Graph tags, canonical URL, language versions, licence, RSS/Atom/JSON feeds, and HTML data tables as columns + rows. Exact values instead of guesses from text. Charged only on success. Price: US$0.002 per successful call (API key credits or x402).
- `preflight`: Free. Before an agent spends money or time on a URL: is it allowed (robots.txt for this service and, if you pass user_agent, for your own bot; Content Signals such as ai-input and ai-train; meta robots), does a bot check or sign-in stand in the way, and which engine each task needs — plain fetch, Kitesurf (Cloudflare's lightweight agent browser) or Chromium. Rate-limited per IP.
- `read`: Returns the main content of a web page as clean Markdown with absolute links. Tries the cheapest way that works: plain fetch, then Kitesurf, then Chromium, and reports which one worked. Refuses (and charges nothing) when the site's robots.txt or Content Signals say no, or when a bot check answers instead of the page. Charged only on success. Price: US$0.004 per successful call (API key credits or x402).
- `screenshot`: PNG screenshot of a page at 1280×800 (or the full page). engine "auto" uses Kitesurf unless the page needs video or WebGL, then Chromium. Charged only on success. Price: US$0.008 per successful call (API key credits or x402).
- `site`: Free. Everything an agent should know about a website before using it: its llms.txt (and llms-full.txt), sitemap (page count and first URLs), feeds, language versions, Content Signals, and which known AI crawlers and agents its robots.txt allows. Rate-limited per IP.
