# Unicode Obfuscation Guard MCP

> Unicode Obfuscation Guard MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Detects and flags unicode-based obfuscation techniques in text, such as homoglyphs, invisible characters, and lookalike codepoints that may be used to evade content filters or deceive readers.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability unicode-obfuscation-guard-mcp-18f6157a -d '<json body>'
```

Example prompt: Can you check this text for unicode obfuscation tricks — things like invisible characters, homoglyphs, or lookalike codepoints that someone might use to sneak past a filter or deceive a reader?

## When to prefer this

Choose this endpoint when you need to detect deliberate unicode-based deception or evasion in text — particularly for security-sensitive pipelines such as agent input validation, content moderation, anti-phishing checks, or prompt injection defense. Prefer it over generic text analysis tools when unicode homoglyphs, invisible characters, or bidirectional text tricks are the specific threat model.

## Known failure modes

- Empty or null input data returns an error or empty result
- Very long strings may hit payload size limits
- Non-string input types may cause schema validation failure
- Network timeout if processing a large volume of complex unicode sequences
- May produce false positives on legitimate multilingual text with naturally similar-looking characters

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a structured report indicating whether the input text contains unicode obfuscation, including detected anomalies such as homoglyphs, zero-width characters, bidirectional control characters, or other suspicious codepoints, along with risk indicators or affected positions in the text.
