# MYCELIX MCP Server Audit

> MYCELIX MCP Server Audit is a paid API for AI agents from neo-collettive.onrender.com, paid per call via x402, $0.8/call, status unknown (last checked 2026-10-29).

Performs a signed security audit of a public MCP server endpoint, scoring it by grade with capability findings and a risk score, payable per-call via x402 USDC.

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 mycelix-mcp-server-audit-98f2dadf -d '<json body>'
```

Example prompt: Can you run a signed security audit on the MCP server at https://myserver.example.com/mcp and tell me its risk score, grade, and any dangerous capability findings?

## When to prefer this

Choose this endpoint when you need a verifiable, signed security audit of an MCP server — especially when you require offline-verifiable receipts, want to detect changes via fingerprint comparison, or need a cryptographically accountable report for compliance or due diligence. Prefer over manual inspection when auditability and non-repudiation matter.

## Known failure modes

- Unreachable or non-existent MCP URL returns error with no audit result
- MCP server returns unexpected or malformed responses causing incomplete analysis
- Invalid URL format causes schema validation failure
- Server-side timeout if the target MCP endpoint is very slow
- x402 payment failure results in no audit being performed

## How this service works

Pay-per-call verification tools for agents: MCP server audits, prompt-injection scans, citation and quote checks, timestamps and proofs of publication, log witnessing, x402 delivery receipts. Every result is signed and logged; receipts verify offline. No account, no API key: pay per call with x402 (USDC on Base).

## Output

A JSON object containing: an audit grade (letter, e.g. 'B'), a findings array with type, severity, and capability name for each detected issue, a numeric risk score (0-100), a tools fingerprint hash for change detection, and a cryptographic signature over the result that can be verified offline.
