# SYNTHORA MCP Server Security Scanner

> SYNTHORA MCP Server Security Scanner is a paid API for AI agents from api.hergertsynthora.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-13).

Probes an MCP server via JSON-RPC and runs a deterministic rule engine to detect security vulnerabilities, returning a security score and findings list

## Facts

- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13

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 synthora-mcp-server-security-scanner-843dca02 -d '<json body>'
```

Example prompt: Can you security-scan the MCP server at https://mcp.example.com/rpc and tell me its security score and any dangerous capabilities or embedded secrets it found?

## When to prefer this

Choose this endpoint when you need a zero-LLM, deterministic, cryptographically signed security assessment of an MCP server before connecting an AI agent to it. Prefer it over manual review when you need a consistent, rule-based security score rather than an LLM opinion, and when you need tamper-evident Ed25519-signed results for audit trails.

## Known failure modes

- MCP server URL is unreachable or returns non-JSON-RPC response
- Manifest provided is malformed or missing required serverInfo/tools fields
- Target server does not respond to JSON-RPC initialize or tools/list calls
- Payment of 0.05 USDC via x402 on Base not fulfilled — request rejected
- Server timeout if target MCP endpoint is slow to respond

## How this service works

MCP Server Security Scan: probes an MCP server (JSON-RPC initialize + tools/list) and applies a deterministic rule engine over its tools — embedded secrets, dangerous shell/exec/filesystem capabilities, prompt-injection surface, hidden unicode, permissive input schemas, and auth/TLS/CORS headers — returning a security_score + findings[]. The trust layer for the agent economy. Zero-LLM, Ed25519-signed. 0.05 USDC via x402 on Base. SYNTHORA.

## Output

Returns a security_score (numeric trust rating) and a findings[] array detailing specific vulnerabilities detected — including embedded secrets, dangerous shell/exec/filesystem tool capabilities, prompt-injection surface areas, hidden unicode characters, overly permissive input schemas, and missing auth/TLS/CORS headers. Response is Ed25519-signed for verifiability.
