## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `web_monitor_delete`

- The name "web_monitor_delete" says "delete": a word for removing or ending something.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- The server marks it not destructive (destructiveHint: false), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Delete one scheduled change monitor owned by the calling IP (its event history is removed too). When to use: the user no longer needs to watch a page, or the per-IP monitor limit was reached. Do not use: to pause a monitor temporarily - there is no pause; delete and re-create. Returns: {ok, deleted, monitor_id, note}; unknown or foreign ids return {ok:false,error:'monitor_not_found'} and delete nothing. Free (not metered); rate-limited to 20 calls/min per IP.
```

## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `web_screenshot`

- The name "web_screenshot" says "screenshot": a word for reading.
- The description's first verb is "capture": a word that usually means money moves, which cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The name "web_screenshot" says "screenshot" and "web": it reads web pages, which anyone can write. The description's first sentence says "capture" and "web": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Capture a screenshot of one public web page as an image (JPEG) plus metadata. When to use: visual layout matters - a dashboard, chart, UI state, or 'what does this page look like'. Do not use: to read text (use web_fetch), for pages behind a login or paywall, or for bulk capture. Returns: image content (image/jpeg) plus {url, final_url, title, width, height, bytes, engine, elapsed_ms, _metering}. Rendered by a real Chromium browser, robots.txt-respecting, SSRF-guarded, max 3MB per image. Metered: shares the web free bucket (100 calls/day per IP shared by all twelve web tools), then 2 credits per call over x402 - there is no API key; the 402 answer carries accepts[].
```

## Changes things (10)

Creates or changes something that can be changed back. Claude Code: ask.

### `dev_trending`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Developer ecosystem trends: GitHub repos, Hugging Face models, npm packages, PyPI stats and Hacker News. When to use: choosing a library/model, seeing what developers are adopting, checking package health. Do not use: for general web search (web_search) or social hot lists (social_hot).

Drive a real Chromium browser on one public page: click, type, press keys, scroll, wait for selectors, then return the resulting text (and optionally a screenshot and JSON XHR responses). When to use: the page needs interaction before its content appears (cookie banners, tabs, 'load more', form submit) and web_fetch/web_crawl cannot see it. Do not use: for plain reading (web_fetch) or bulk crawling (web_crawl); no login/paywall bypass. Returns: {ok, url, final_url, title, markdown, chars, elapsed_ms, screenshot?, xhr?, took_ms, _metering}. Max 10 actions; screenshot returns MCP image content.

Do not use: to mirror a whole site (hard cap 20 pages, same host), or for one page (web_fetch). Returns: {ok, url, final_url, count, pages:[{url, title, status, chars, content}], cached, took_ms, _metering}. Respects robots.txt and SSRF guards; partial page failures are skipped. Metered: shares the web free bucket (100 calls/day per IP shared by all web tools), then 3 credits per call over x402 - no API key.

Submit a same-host crawl as an asynchronous job and return a job_id immediately. When to use: you need more than a couple of pages and cannot hold a long HTTP request; submit here, then poll web_crawl_job until status is done, failed or cancelled. Do not use: for one page (web_fetch) or when you need the result in this call (web_crawl). Returns: {ok, job_id, status, url, depth, max_pages, max_chars, idempotent, poll_with}. Pass idempotency_key to retry safely (24h window returns the same job). Metered: shares the web free bucket (100 calls/day per IP), then 3 credits per submit over x402.
```

### `web_crawl_job`

Description, as the server wrote it:

```untrusted-server-text
Check or cancel an asynchronous crawl job created by web_crawl_async. When to use: after web_crawl_async, poll with action=status until status is done/failed/cancelled; use action=cancel to stop a running job. Do not use: to start a crawl (web_crawl_async) or for a quick one-page read (web_fetch). Returns status: {ok, job_id, status: queued|running|done|failed|cancelled, progress:{pages_done,max_pages}, created_at, updated_at, result?, error?}. Free (not metered); rate-limited.

```untrusted-server-text
Extract a page's structured data into a named schema's common fields (no LLM): article, product, event, faq, recipe, course, organization, local_business, breadcrumb, dataset or job_posting. When to use: you need fields (title/author/date, price/currency/availability, event dates, FAQ Q&A, recipe ingredients, org address) rather than raw markdown or tables.

Extract a page's structured metadata: Open Graph, Twitter cards, canonical URL, language and JSON-LD. When to use: you need the title/description/author/image of a page, or JSON-LD structured data for a product/article, without reading the whole page. Do not use: when you need the page text (use web_fetch) or a screenshot (use web_screenshot).

- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Create a scheduled change monitor for one public URL: the server re-fetches the page on an interval, stores a new snapshot and records a diff event whenever the readable text changes. When to use: the user wants to be told when a page changes (price, docs, policy page, job post, release notes) and cannot poll it themselves; also for handing off 'watch this for me'. Do not use: for a single comparison right now (web_diff) or when you only need the page today (web_fetch). Returns: {ok, monitor_id, url, status:active, interval_minutes, next_check_ts, webhook_enabled, webhook_secret?, webhook_signature?, hint}. The first check runs within ~60s to store the baseline; later changes show up in web_monitor_list.recent_events and, if requested, are POSTed to webhook_url. Webhook: https only, no redirects, 8s timeout, up to 2 retries (30s/120s); body JSON {monitor_id,url,ts,changed,added_lines,removed_lines,title,diff,event_id}; verify header 'X-RobotBase-Signature: sha256=<hex HMAC-SHA256 of the raw body using webhook_secret>'. Limits: 15-1440 minutes; max 5 monitors per IP; monitors expire after 7 days. Metered: 1 credit (shares the web free bucket of 100 calls/day per IP).

- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Fetch a page now and compare it with the previous snapshot of the same URL, returning whether it changed and a unified diff (no LLM).

Do not use: for one-off reading (web_fetch) or structured fields (web_extract_schema). Returns: {ok, url, baseline, changed, diff, added_lines, removed_lines, previous_ts, current_ts, title, hash, chars, fetched_cached, took_ms, _metering}. fresh=true (default) adds a cache-busting query to bypass the 6h page cache; pass fresh=false to compare cached content.

Do not use: to crawl or mirror a site, to fetch a page behind a login or paywall, to read API/RPC endpoints, or for book text inside CyberLibrary (use cyberlibrary_get_chapter). Returns: {url, final_url, status, title, content, chars, truncated, fetched_at, source (direct|provider), cached, took_ms, _metering}. The response is capped at 12000 characters per call; raise max_chars (up to 20000) when you need more. Reads one public URL only, respects robots.txt, and does not bypass login or paywall. Direct fetch is tried first; pages blocked from this node are fetched through a provider and marked source=provider. Metered: all web tools share 100 free calls/day per IP (separate from the risk/library allowance), then 1 credit per call over x402 - there is no API key; the 402 answer carries accepts[].

When to use: search returned several candidate pages and you want a first pass over all of them; then call web_fetch on the ones worth reading in full. Do not use: when you need the complete text of a page (use web_fetch), or to crawl a site (use web_map). Returns: {ok, count, ok_count, results:[{url, ok, final_url, status, title, engine, chars, snippet, error?}], took_ms, _metering}. Partial failures do not fail the whole call. Metered: counts one call per URL against the shared web free bucket (50 URLs/day per IP together with web_fetch), then 1 credit per URL over x402 - max 5 URLs per call, no API key.
```

Search the live web and get ranked results with title, URL, snippet and published date. When to use: an agent needs current facts, news or links that are not on chain - 'what is the BTC fee market saying today', 'recent Zcash governance proposals', 'find the docs page for X'. Use it before web_fetch, then fetch the one URL that looks authoritative. Do not use: for on-chain facts (use the BTC/ETH/XMR/ZEC/TRON tools) or for content inside a CyberLibrary book (use cyberlibrary_fulltext_search). Provider: self-hosted SearXNG (Bing/Baidu/360/Sogou/Yandex/Marginalia) first, then Serper, Tavily and cn.bing RSS as automatic fallbacks. Returns: {query, count, results:[{title,url,snippet,published}], provider (serper|tavily|bing_rss), cached, took_ms, _metering}. Results may be cached for up to 10 minutes; a cached result still counts as one call against the free allowance. Metered: all web tools share 100 free calls/day per IP (separate from the risk/library allowance), then 1 credit per call over x402 - there is no API key; the 402 answer carries accepts[]. max count is 10.
