Firecrawl MCP Server

firecrawl_scrape

Extract content from a specific webpage using advanced scraping options, including format selection, content filtering, and cached data for faster results.

Instructions

Scrape content from a single URL with advanced options. This is the most powerful, fastest and most reliable scraper tool, if available you should always default to using this tool for any web scraping needs.

Best for: Single page content extraction, when you know exactly which page contains the information. Not recommended for: Multiple pages (use batch_scrape), unknown page (use search), structured data (use extract). Common mistakes: Using scrape for a list of URLs (use batch_scrape instead). If batch scrape doesnt work, just use scrape and call it multiple times. Prompt Example: "Get the content of the page at https://example.com." Usage Example:

{
  "name": "firecrawl_scrape",
  "arguments": {
    "url": "https://example.com",
    "formats": ["markdown"],
    "maxAge": 3600000
  }
}

Performance: Add maxAge parameter for 500% faster scrapes using cached data. Returns: Markdown, HTML, or other formats as specified.

Input Schema

NameRequiredDescriptionDefault
urlYesThe URL to scrape
formatsNoContent formats to extract (default: ['markdown'])
onlyMainContentNoExtract only the main content, filtering out navigation, footers, etc.

Behavior4/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively adds context beyond the input schema by mentioning performance aspects ('500% faster scrapes using cached data'), return formats ('Returns: Markdown, HTML, or other formats as specified'), and reliability claims ('most powerful, fastest and most reliable'). However, it lacks details on error handling, rate limits, or authentication needs, which would be beneficial for a tool with 14 parameters.

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?

The description is well-structured with clear sections (e.g., 'Best for,' 'Not recommended for,' 'Common mistakes,' 'Prompt Example,' 'Usage Example,' 'Performance,' 'Returns'), making it easy to scan. It is appropriately sized for a complex tool, though some sections like 'Prompt Example' and 'Usage Example' are slightly redundant, and the opening claim ('most powerful, fastest and most reliable') could be more concise.

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?

Given the tool's complexity (14 parameters, nested objects, no output schema, no annotations), the description is largely complete. It covers purpose, usage guidelines, performance tips, and return formats, which compensates well for the lack of annotations and output schema. However, it could improve by detailing error cases or response structures, especially for a tool with advanced options like 'actions' and 'extract.'

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 the schema already documents all 14 parameters thoroughly. The description adds minimal parameter-specific information beyond the schema, such as a performance tip for 'maxAge' and a general note on return formats. This meets the baseline of 3, as the schema does the heavy lifting, but the description doesn't significantly enhance parameter understanding.

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?

The description clearly states the tool's purpose as 'Scrape content from a single URL with advanced options,' specifying the verb (scrape) and resource (single URL content). It explicitly distinguishes from siblings like batch_scrape, search, and extract in the 'Best for' and 'Not recommended for' sections, making the differentiation clear and specific.

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?

The description provides explicit guidance on when to use this tool vs. alternatives: 'Best for: Single page content extraction... Not recommended for: Multiple pages (use batch_scrape), unknown page (use search), structured data (use extract).' It also includes a 'Common mistakes' section warning against misuse and naming specific sibling tools, offering clear when/when-not/alternatives.

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