# HTML DOM Depth Calculator MCP for AI Agents MCP

> HTML DOM Depth Calculator helps you check if an HTML string is too deep or broken before your scraper tries to process it. It prevents crashes by finding unbalanced tags and measuring how complex a page's structure actually is, making it essential for stable web scraping automation.

## Description

When you are running large-scale web scraping tasks, a single malformed HTML file can crash your entire pipeline or eat up all your available memory. This MCP lets your agent inspect raw HTML strings to see how deep the nesting goes and if any tags are left unclosed before you even start parsing. It is basically a safety check for your automation scripts. Instead of guessing if a page is safe, you can get an exact count of the hierarchy depth and structural errors. You can connect this directly to your existing setup through Vinkius, so your scraping agents can automatically skip or flag high-risk pages without manual intervention.

## Tools

### assess_scraping_complexity
Determines how risky a specific HTML string is to scrape. Use this to flag pages that might cause high resource usage.

### compute_max_nesting_depth
Finds the exact maximum nesting depth of your tags. This helps you predict memory usage for deep DOM trees.

### analyze_tag_metrics
Checks for total tags and structural errors in your HTML. It helps you find broken markup that might break a parser.

## Prompt Examples

**Prompt:** 
```
How deep is this HTML structure?
```

**Response:** 
```
The maximum nesting depth for that structure is 3.
```

**Prompt:** 
```
Check if this HTML has any broken tags.
```

**Response:** 
```
The analysis shows 1 total tags parsed and 1 unbalanced tags count.
```

**Prompt:** 
```
Is it safe to scrape this page?
```

**Response:** 
```
The risk level is LOW and it is safe to scrape.
```

## Capabilities

### Detect unbalanced HTML tags
Finds unclosed or mismatched tags that cause parser crashes.

### Measure nesting depth
Calculates the deepest level of hierarchy in a string to predict memory usage.

### Evaluate scraping risk
Determines if a target page is safe or too complex for high-scale extraction.

### Audit structural errors
Identifies broken markup and tag counts within raw HTML content.

## Use Cases

### Broken tags crashing the pipeline
A scraper hits a malformed page and crashes. Your agent uses analyze_tag_metrics to identify the error and skip it.

### High memory usage on deep pages
You are worried about recursion limits. The agent runs compute_max_nesting_depth and decides whether to proceed.

### Scaling scraping without manual checks
You need to vet thousands of URLs. Your agent uses assess_scraping_complexity to categorize pages by risk level.

## Benefits

- Stop memory exhaustion by identifying deep HTML hierarchies before parsing starts.
- Avoid broken pipelines using analyze_tag_metrics to catch unclosed tags early.
- Predict resource needs for your agents with precise depth measurements from compute_max_nesting_depth.
- Reduce scraping failures by using assess_scraping_complexity to flag high-risk pages.
- Automate structural audits of raw HTML strings without writing custom regex or parsers.

## How It Works

The bottom line is you stop scraper crashes before they happen.

1. Pass a raw HTML string to your agent.
2. The MCP analyzes the tag structure and nesting levels.
3. You receive specific metrics on depth, error counts, and scraping risk.

## Frequently Asked Questions

**How can HTML DOM Depth Calculator prevent scraper crashes?**
It identifies unbalanced tags and deep nesting before your parser attempts to process the content, stopping errors at the source.

**Can I use HTML DOM Depth Calculator for large scale web scraping?**
Yes, it is designed to help you assess the risk of high-scale scraping by checking structural complexity.

**Does HTML DOM Depth Calculator work with any AI client?**
It works with any MCP-compatible client like Claude, Cursor, or Windsurf through the Vinkius catalog.

**How does HTML DOM Depth Calculator help with memory management?**
By measuring the maximum nesting depth of HTML tags, it helps you avoid processing pages that could cause memory exhaustion.

**Will HTML DOM Depth Calculator find unclosed div tags?**
Yes, it analyzes the string for structural errors and identifies unbalanced tags that could break your parser.

**How does this tool prevent scraper crashes?**
It uses `assess_scraping_complexity` to identify high-risk HTML structures with extreme nesting or unbalanced tags before your parser attempts to process them.

**Can I use this for malformed HTML?**
Yes, the `analyze_tag_metrics` tool specifically tracks unbalanced tags to help you understand how broken the HTML structure is.

**What information does `compute_max_nesting_depth` return?**
It returns the peak number of overlapping open elements found within the provided HTML string.
