# Flashloan Attack Fuzzer MCP

> Flashloan Attack Fuzzer MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.35/call, status unknown (last checked 2026-10-12).

Fuzzes smart contracts and DeFi protocols for flashloan attack vulnerabilities by simulating attack vectors and identifying exploitable patterns.

## Facts

- Price: $0.35/call
- Payment: x402

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 flashloan-attack-fuzzer-mcp-330bdcf7 -d '<json body>'
```

Example prompt: Can you fuzz my DeFi lending contract for flashloan attack vulnerabilities? Here's the contract code: [paste contract code] — I want to know if it's exploitable via a single-transaction flashloan attack.

## When to prefer this

Choose this endpoint when you need automated flashloan-specific attack fuzzing for DeFi smart contracts, especially before deployment or after a suspicious on-chain event. Prefer over generic static analyzers when the threat model is specifically flashloan-based single-transaction exploits (price manipulation, reentrancy, arbitrage).

## Known failure modes

- Malformed or missing 'data' field returns a 400 error
- Unparseable or non-contract input yields empty or error result
- Complex multi-contract interactions may produce incomplete analysis
- Payment failure (x402) blocks the call before processing
- Timeout on very large contract inputs

## 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 vulnerability report identifying potential flashloan attack vectors, exploit paths, risk severity ratings, and details on which contract functions or logic flows are susceptible to single-transaction flashloan manipulation.
