Scrape a page

scrape
Read-only

Read one URL as Markdown with its Evidence Record (final URL, fetch time, HTTP status, robots.txt decision, hashes), over HTTP first and in the browser when the page needs it. Not for: many URLs or a whole site section. Compact by default; debug adds the full audit. warnings name what the content cannot vouch for (client_rendered_suspected, robots_overridden), and agentHints the next step.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Input Schema

NameRequiredDescriptionDefault
urlYesAn http(s) URL.
modeNoThe declared identity the page is read under: standard (default) or research. A hosted server holds no saved logins, so it has no authed mode.
debugNoReturn the full audit: trace, ladderTrace and every attempt.
mobileNoRead as declared mobile Chrome (Android UA, 412x915). Default false.
verifyNoChecks on final delivery; passed covers configured checks only. Inspect failure/readiness before retrying. tableRowsMin needs tables format (zero-based columns); recordFields uniqueBy counts complete extracted identities; markdownExcludes needs another check beside it. Markdown checks need markdown format.
formatsNoWhat to return (default markdown): markdown, links, html, rawHtml, images, tables, json, attributes ({ selectors }), list ({ itemSelector?, fields? }: a record per repeated item, detected without itemSelector), screenshot or screenshot@fullPage (browser only). This connection has no browser lane, so it offers no screenshot.
headersNoExtra headers to the page's origin, recorded; User-Agent, client hints, authorization and cookie refused.
timeoutNoDeadline in milliseconds for the whole scrape. When it fires the result is partial with the content so far, or failed/timeout. Here by default 120000, max 180000; a longer one is lowered to it.
blockAdsNoBlock ad hosts, ads and cookie banners in the browser. Default true.
fastModeNoHTTP only: a page needing scripts gets the HTTP verdict (a shell: failed/empty_unverified). Default false.
excludeTagsNoCSS selectors removed with their contents.
includeTagsNoCSS selectors of the only elements to keep, whatever onlyMainContent says (no sibling combinators, :nth-child or :has).
integrationNoYour workflow label; recorded, not sent to sites.
includeLinksNoAlso return the page's links. Default false.
maxFileBytesNoLargest file to download; a larger one is failed/body_too_large.
markdownOffsetNoRead on from a cut markdown's truncatedAt.
onlyMainContentNofalse also keeps header, navigation and footer. Default true.
allowlistedDomainsNo
removeBase64ImagesNoDrop data: URI images from the Markdown, keeping alt text. Default true.

TDQS

A4.3/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Goes well past the annotations by disclosing the transport ladder escalation, the warnings vocabulary (client_rendered_suspected, robots_overridden) and agentHints signalling, and that headers like authorization, cookie and User-Agent are refused. It does not say what the default truncation limits are or how much authorization/rate limiting applies beyond the mode note, so it is rich but not exhaustive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loads the core action and output, then the exclusion, then the caveats about warnings and hints. Dense but every clause carries information; the packed middle sentence about warnings and agentHints is the only place where compression costs a little readability.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 19-parameter tool with nested verify/formats objects and an output schema, the description covers the primary read path, the escalation behavior, the compact-vs-debug return distinction and the interpretation of warnings. It leaves the formats and verify machinery to the schema, which is reasonable given the output schema exists.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 95% schema coverage the schema already explains nearly every parameter, so the baseline is 3. The description adds genuine value on top: "Compact by default; debug adds the full audit" ties the debug flag to output shape, and the Evidence Record list explains what the compact return actually contains.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ("Read one URL as Markdown") and immediately names the accompanying artifact (Evidence Record with final URL, fetch time, status, robots decision, hashes). The "Not for: many URLs or a whole site section" clause separates it from the map sibling without the agent needing to open either schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives a clear exclusion (bulk URLs / site sections) which implicitly routes to map, plus an operational rule: HTTP first, browser only when the page needs it. It never names the sibling tool explicitly and says nothing about when to prefer other retrieval paths, so it falls just short of full routing guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
