Installation

# Global installation
npm install -g @modelcontextprotocol/mcp-server-firecrawl

# Local project installation
npm install @modelcontextprotocol/mcp-server-firecrawl

Quick Start

  1. Get your Firecrawl API key from the developer portal

  2. Set your API key:

    Unix/Linux/macOS (bash/zsh):

    export FIRECRAWL_API_KEY=your-api-key

    Windows (Command Prompt):

    set FIRECRAWL_API_KEY=your-api-key

    Windows (PowerShell):

    $env:FIRECRAWL_API_KEY = "your-api-key"

    Alternative: Using .env file (recommended for development):

    # Install dotenv
    npm install dotenv
    
    # Create .env file
    echo "FIRECRAWL_API_KEY=your-api-key" > .env

    Then in your code:

    import dotenv from 'dotenv';
    dotenv.config();
  3. Run the server:

    mcp-server-firecrawl

TDQS

C2.1/5.0
Behavior2/5

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

No annotations exist, so the description must disclose behavior. It does not mention network requests, rate limits, authentication, error handling, or whether it is idempotent. Only states 'extracts', which is vague.

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

Conciseness2/5

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

Very short at 7 words, but under-specified. Lacks structure such as sections or examples. Conciseness would be appropriate if complete, but here it is insufficient.

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

Completeness1/5

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

Given the complexity (6 parameters, nested objects, sibling tools, no output schema), the description is extremely incomplete. No information on return format, usage patterns, or edge cases.

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 baseline is 3. The description does not add any extra meaning beyond the schema's parameter descriptions. No elaboration on how parameters interact.

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

Purpose3/5

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

The description states the tool extracts structured data from URLs, but does not differentiate from sibling 'map'. The verb and resource are clear, but the scope is vague as 'structured data' is not defined.

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

Usage Guidelines1/5

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

No guidance on when to use this tool versus alternatives like 'map', no prerequisites or exclusions provided. The description is insufficient for an agent to decide usage context.

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

mapC

Maps a website's structure

ParametersJSON Schema
NameRequiredDescriptionDefault
urlYesBase URL to map
limitNoMaximum links to return
searchNoSearch query for mapping
timeoutNoRequest timeout
sitemapOnlyNoOnly use sitemap.xml for mapping
ignoreSitemapNoIgnore sitemap.xml during mapping
includeSubdomainsNoInclude subdomains in mapping

TDQS

C2.4/5.0
Behavior1/5

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

No annotations are present, so the description must disclose behavioral traits. It only says 'Maps a website's structure' with no details on whether it crawls, destructiveness, rate limits, or return format. This is insufficient.

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

Conciseness2/5

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

The description is a single, short sentence, which is efficient but under-specified for a tool with 7 parameters. It could include key details without sacrificing conciseness.

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

Completeness1/5

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

Given the tool's complexity (7 parameters, no output schema, no annotations), the description lacks essential context such as return values, process details, or limitations. It is highly incomplete.

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?

The input schema has 100% description coverage for all 7 parameters, so the baseline is 3. The description adds no additional meaning beyond the schema, making it adequate but not improved.

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

Purpose4/5

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

The description states a specific verb ('Maps') and resource ('a website's structure'), making the core purpose clear. However, it does not differentiate from the sibling tool 'extract', which could lead to ambiguity.

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

Usage Guidelines2/5

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

No guidance is provided on when to use this tool versus alternatives (e.g., 'extract'). The description lacks context for selection or prerequisites.

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

C2.7/5.0
Disambiguation5/5

The two tools have clearly distinct purposes: one extracts structured data from URLs, the other maps a website's structure. There is no overlap in functionality.

Naming Consistency5/5

Both tool names are single imperative verbs ('extract' and 'map'), following a consistent and concise naming pattern.

Tool Count3/5

With only 2 tools, the server is on the lower end of acceptable scope. It covers basic functionality but feels minimal for a web crawling service.

Completeness3/5

The server provides core data extraction and site mapping, but lacks advanced features like recursive crawling or search, which are notable gaps for the domain.
