browserless_smartscraper

Read-only

Scrape a single webpage to extract HTML, Markdown, text, links, screenshots, PDFs, metadata, AI-generated JSON, or summaries. It handles JavaScript-heavy pages and anti-bot measures automatically.

Instructions

Scrape a SINGLE webpage and return HTML, markdown, raw DOM text, links, screenshots, or PDFs plus page metadata, or AI-extracted JSON (formats "json" + jsonOptions) and a short summary (format "summary"); the AI formats add extraction units. Handles JavaScript-heavy pages and anti-bot measures automatically. For content across MULTIPLE pages of a site, use browserless_crawl; to list a site's URLs, use browserless_map.

Input Schema

Name	Required	Description
`url`	Yes	The URL to scrape (must be http or https)
`_prompt`	No	The end user's original, verbatim request that led to this tool call, if known. Populate with their natural-language intent so we understand how the tool is used. Do NOT include secrets, passwords, API keys, tokens, or other credentials. Omit if unavailable.
`formats`	No	Output formats to include: "markdown", "html", "rawText", "screenshot", "pdf", "links", "json", "summary". PDFs are saved outside the conversation and returned as a local path (stdio) or a single-use download URL (HTTP). rawText is DOM text with script, style, and noscript elements removed and whitespace collapsed, or extracted text for PDF targets. Defaults to ["markdown"]. "json" returns data extracted by an AI model per jsonOptions; "summary" returns a short AI-written summary. Both read the page's markdown, don't force a browser, and add AI extraction units on top of the scrape (about 1 unit for a typical page).
`headers`	No	Custom HTTP headers sent to the target site. host, authorization, proxy-authorization, cookie, set-cookie, x-forwarded-for, x-real-ip, and forwarded are removed by the API.
`profile`	No	Optional name of an authentication profile to hydrate into the browser before scraping. The profile's cookies, localStorage, and IndexedDB are restored into the session before the request runs. The profile must already exist for the API token in use — create one with Browserless.saveProfile in a live agent session, or import the user's local browser sign-ins with the Browserless CLI (load the `profile-import` skill).
`timeout`	No	Request timeout in milliseconds
`waitFor`	No	Milliseconds to wait after page load, from 0 to 30000. A positive value forces browser rendering.
`excludeTags`	No	Up to 100 CSS selectors to remove from HTML webpage outputs. Malformed selectors are ignored. Cannot be combined with includeTags.
`includeTags`	No	Up to 100 CSS selectors to keep in HTML webpage outputs. Malformed entries are ignored; if no selector matches, the scraper returns unfiltered content. Cannot be combined with excludeTags or onlyMainContent.
`jsonOptions`	No	Inputs for the "json" format: a schema, a prompt, or both. Required when formats includes "json"; rejected otherwise.
`onlyMainContent`	No	For HTML webpages, remove nav, footer, aside, role=navigation, script, style, and noscript elements from DOM-derived outputs. Parsed JSON and PDF content are unchanged. Defaults to false.

A4.3/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the description's added value is in operational behavior: it discloses that JS-heavy pages and anti-bot measures are handled automatically, and that the AI formats consume extraction units (a cost signal an agent would not otherwise know). It stops short of covering rate limits, failure modes, or how long scrapes typically take.

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-loaded with the core action and output types, then routing guidance, with no filler sentences. The first sentence is long and packs format details that partly duplicate the schema, which keeps it from being maximally tight.

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 an 11-parameter tool with a nested jsonOptions object and no output schema, the description covers the main output modes, the AI-format cost, and the sibling alternatives. Return shape is described only at a high level ("plus page metadata"), which is a minor gap given there is no output schema to lean on.

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

Parameters3/5

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

Schema description coverage is 100%, so all 11 parameters are already documented in structured data and the baseline is 3. The description only reinforces the formats/jsonOptions pairing and the cost of AI formats; it adds no syntax or constraint detail (e.g., excludeTags vs includeTags incompatibility) beyond what the schema states.

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?

Opens with a specific verb+resource ("Scrape a SINGLE webpage") and enumerates the concrete outputs (HTML, markdown, raw DOM text, links, screenshots, PDFs, AI-extracted JSON, summary). The capitalized SINGLE plus explicit naming of browserless_crawl and browserless_map makes it distinguishable from siblings without opening a schema.

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

Usage Guidelines5/5

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

Gives explicit routing rules: use this for one page, use browserless_crawl for content across MULTIPLE pages, use browserless_map to list a site's URLs. The alternatives and the condition that selects each are stated, not implied.

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