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) and a findings[] array detailing specific issues found: embedded secrets, dangerous shell/exec/filesystem tools, prompt injection surface exposure, hidden unicode, permissive input schemas, and auth/TLS/CORS header misconfigurations. Response is Ed25519-signed for integrity assurance.
Example use cases
Example prompt
“Can you security-scan the MCP server at https://myserver.example.com/mcp — I want to know if it has any embedded secrets, dangerous shell capabilities, or prompt injection risks before I let my agent connect to it?”
Technical details
Endpoint
POSThttps://mcpscan.hergertsynthora.com/serviceWhen to prefer
Use this endpoint when you need to vet an MCP server before connecting an AI agent to it — especially when evaluating third-party or community MCP servers. Prefer this over manual review when you need a deterministic, rule-based (zero-LLM) security score with cryptographically signed results. Ideal for agent orchestration pipelines that need automated trust gating before tool registration.
Side effects
- MCP server URL unreachable or returns non-JSON-RPC response
- Provided manifest missing required serverInfo or tools fields
- Invalid URL format in request body
- MCP server times out during JSON-RPC initialize probe
- Payment not completed (x402 402 response returned before scan executes)
