## Description

You're trying to get your marketing copy approved, but the legal team keeps sending it back because of "vague claims." This MCP handles that headache for you. It acts as a first pass to find every piece of text that might trigger a regulatory red flag. Instead of you manually hunting for every percentage or "best in class" statement, your AI client can scan the entire doc to see what's missing a citation or a baseline. It identifies where you've made a bold promise without a qualifier and highlights the specific spots that need a footnote. Using this MCP within the Vinkius catalog means you can move from "hope this passes" to "this is ready for review" in a few seconds. It gives you a clear list of what to fix so you can get your campaign live without the back-and-forth.

## Tools

### comparative_claims_check
Finds comparative words like "faster" or "better" that don't have a baseline. It helps you avoid making unsubstantiated comparisons.

### compliance_scan
Runs a full audit on your provided text to find all issues at once. It gives you a final score for the whole document.

### unsupported_numerics_check
Locates statistics or percentages that lack citations or context. It ensures every number you use is actually backed up.

### absolute_statements_check
Flags bold statements like "always" or "guaranteed" that lack necessary qualifiers. It helps you stay within regulatory boundaries.

## Prompt Examples

**Prompt:** 
```
Check this for compliance: 'Our software is the fastest and works 100% of the time.'
```

**Response:** 
```
I found a few issues with that copy:

* **'fastest'** is a comparative claim without a benchmark.
* **'100% of the time'** is an unsupported numeric claim without a citation.
* **'works'** is an absolute statement that needs a qualifier (like "typically").
```

**Prompt:** 
```
Is this claim okay: '9 out of 10 users prefer our brand over the competition'?
```

**Response:** 
```
That claim has two issues:

1. **'9 out of 10'** is a numeric claim missing a source.
2. **'prefer our brand'** is a comparative claim that doesn't specify who the competition is.
```

**Prompt:** 
```
Run a full audit on this landing page copy: [Paste text]
```

**Response:** 
```
I've completed the audit. Here is your compliance summary:

**Overall Score: 65%**

**Issues Found:**
* 3 unsupported numeric claims
* 2 comparative claims without benchmarks
* 1 absolute statement missing a qualifier

*Would you like me to rewrite these specific lines for you?*
```

## Capabilities

### Find missing citations
Identifies percentages and statistics that aren't backed by a source.

### Flag comparative claims
Locates superlatives like "faster" or "better" that lack a clear benchmark.

### Identify absolute guarantees
Highlights bold statements like "always" that need qualifying language.

### Generate compliance scores
Provides a single score for the overall substantiation of your text.

### Audit entire documents
Scans long-form copy to find all regulatory risks in one pass.

## Use Cases

### Fixing comparative claims in ads
A copywriter writes "Our app is the fastest in the market." The agent flags "fastest" as a comparative claim without a benchmark.

### Verifying statistics in whitepapers
A brand wants to say "90% of users love us." The agent identifies the missing citation for the 90% statistic.

### Checking landing page guarantees
A landing page says "Guaranteed results every time." The agent flags "guaranteed" and "every time" as absolute statements needing qualifiers.

### Bulk auditing campaign assets
A marketing lead needs to audit 10 different ads quickly. The agent uses `compliance_scan` to provide a score for all of them.
