Prompt Routines

mcp-server-webcrawl provides toolkits for free - style searching of web - crawl data. It can also run routines (as prompts). You can either write your own prompts or use the provided ones. These prompts are copy - and - paste and used as raw Markdown.

Prompt	Download	Category	Description
🔍 SEO Audit	`auditseo.md`	audit	Technical SEO (search engine optimization) analysis. Covers the basics, with options to dive deeper.
🔗 404 Audit	`audit404.md`	audit	Broken link detection and pattern analysis. Not only finds issues, but suggests fixes.
⚡ Performance Audit	`auditperf.md`	audit	Website speed and optimization analysis. Real talk.
📁 File Audit	`auditfiles.md`	audit	File organization and asset analysis. Discover the composition of your website.
🌐 Gopher Interface	`gopher.md`	interface	An old - fashioned search interface inspired by the Gopher clients of yesteryear.
⚙️ Search Test	`testsearch.md`	self - test	A battery of tests to check for Boolean logical inconsistencies in the search query parser and subsequent FTS5 conversion.

If you want to shortcut the site selection, paste the markdown and in the same request, type "run pasted for [site name or URL]." When pasted without additional context, you will be prompted to select from a list of crawled sites.

Boolean Search Syntax

The query engine supports field - specific (field: value) searches and complex boolean expressions. Fulltext search combines the url, content, and headers fields.

Query Example	Description
privacy	fulltext single keyword match
"privacy policy"	fulltext match exact phrase
boundar*	fulltext wildcard matches results starting with boundar (boundary, boundaries)
id: 12345	id field matches a specific resource by ID
url: example.com/somedir	url field matches results with URL containing example.com/somedir
type: html	type field matches for HTML pages only
status: 200	status field matches specific HTTP status codes (equal to 200)
status: >=400	status field matches specific HTTP status code (greater than or equal to 400)
content: h1	content field matches content (HTTP response body, often, but not always HTML)
headers: text/xml	headers field matches HTTP response headers
privacy AND policy	fulltext matches both
privacy OR policy	fulltext matches either
policy NOT privacy	fulltext matches policies not containing privacy
(login OR signin) AND form	fulltext matches fulltext login or signin with form
type: html AND status: 200	fulltext matches only HTML pages with HTTP success

Field Search Definitions

Field search allows you to specify which columns of the search index to filter, improving search precision.

Field	Description
id	database ID
url	resource URL
type	enumerated list of types (see types table)
size	file size in bytes
status	HTTP response codes
headers	HTTP response headers
content	HTTP body—HTML, CSS, JS, and more

Field Content

A subset of fields can be independently requested with results, while core fields are always included.

Field	Description
id	always available
url	always available
type	always available
status	always available
created	on request
modified	on request
size	on request
headers	on request
content	on request

Content Types

The type: field search allows filtering by broad content type groups.

Type	Description
html	webpages
iframe	iframes
img	web images
audio	web audio files
video	web video files
font	web font files
style	CSS stylesheets
script	JavaScript files
rss	RSS syndication feeds
text	plain text content
pdf	PDF files
doc	MS Word documents
other	uncategorized

Extras

The extras parameter provides additional processing options.

Extra	Description
thumbnails	Generates base64 encoded images to be viewed and analyzed by AI models. Enables image description, content analysis, and visual understanding while keeping token output minimal. Works with images, which can be filtered using `type: img` in queries. SVG is not supported.
markdown	Provides the HTML content field as concise Markdown, reducing token usage and improving readability for LLMs. Works with HTML, which can be filtered using `type: html` in queries.
regex	Extracts regular expression matches from crawled files such as HTML, CSS, JavaScript, etc. Not as precise a tool as XPath for HTML, but supports any text file as a data source. One or more regex patterns can be requested, using the `extrasRegex` argument.
snippets	Matches fulltext queries to contextual keyword usage within the content. When used without requesting the content field (or markdown extra), it can provide an efficient means of refining a search without pulling down the complete page contents. Also great for rendering old school hit - highlighted results as a list, like Google search in 1999. Works with HTML, CSS, JS, or any text - based, crawled file.
xpath	Extracts XPath selector data, used in scraping HTML content. Use XPath's text() selector for text - only, element selectors return outerHTML. Only supported with `type: html`, other types will be ignored. One or more XPath selectors (//h1, count(//h1), etc.) can be requested, using the `extrasXpath` argument.

Extras help produce token - efficient HTTP content responses. Markdown reduces the size of source HTML, snippets are small in size, and XPath can be customized. If your LLM shows an affinity for the "content" field, you can suggest using the extras feature to manage token budget.
