Firecrawl MCP Multiple Keys

by AdvaitR7

firecrawl_crawl

Crawl a website to extract content from multiple related pages, automatically polling until complete and returning final status and data.

Instructions

Starts a crawl job on a website, polls until it reaches a terminal state, and returns the final crawl status/data.

Best for: Extracting content from multiple related pages, when you need comprehensive coverage. Not recommended for: Extracting content from a single page (use scrape); when token limits are a concern (use map + scrape for tighter control); when you need fast results (crawling can be slow). Warning: Crawl responses can be very large and may exceed token limits. Limit the crawl depth and number of pages, or use map + scrape for tighter control. Common mistakes: Setting limit or maxDiscoveryDepth too high (causes token overflow) or too low (causes missing pages); using crawl for a single page (use scrape instead). Using a /* wildcard is not recommended. Prompt Example: "Get all blog posts from the first two levels of example.com/blog." Usage Example:

{
  "name": "firecrawl_crawl",
  "arguments": {
    "url": "https://example.com/blog/*",
    "maxDiscoveryDepth": 5,
    "limit": 20,
    "allowExternalLinks": false,
    "deduplicateSimilarURLs": true,
    "sitemap": "include"
  }
}

Returns: Final crawl status and data after internal polling, including the crawl id. Use firecrawl_check_crawl_status only when you need to re-check an existing crawl ID later.

Behavior4/5

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

Annotations provide readOnlyHint=false and destructiveHint=false, but description adds key behavioral context: polling until terminal state, large response warnings, token limit concerns, and relationship to check_crawl_status. However, details on failure behavior or polling mechanism are missing.

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?

Well-structured with clear sections (Best for, Not recommended, etc.) and front-loaded main action. Slightly verbose with example and prompts, but mostly efficient. Could reduce repetition of token limit warnings.

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

Completeness3/5

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

For a complex tool with 17 parameters and nested objects, the description provides high-level guidance and distinguishes from siblings, but lacks detailed parameter descriptions. No output schema; return type is vaguely described as 'final crawl status/data'. Adequate but not complete.

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

Parameters2/5

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

Schema description coverage is 0%, and the description only mentions a few parameters in the usage example and common mistakes (limit, maxDiscoveryDepth, url). Most parameters (e.g., delay, webhook, scrapeOptions) are not explained, leaving agents to rely solely on schema names.

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 starts a crawl job, polls until terminal state, and returns status/data. It specifically distinguishes from siblings like firecrawl_scrape (single page) and firecrawl_map, making the purpose unambiguous.

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?

Explicitly lists best use cases (multiple related pages), not recommended cases (single page, token concerns, speed), and provides alternatives (scrape, map + scrape). Includes common mistakes and a prompt example, offering comprehensive guidance.

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