How this service works
MCP SERVER TRUST / SECURITY CHECK: verify BEFORE connecting whether an MCP server is safe to trust — reachability, MCP handshake, HTTPS, advertised tools, risky capabilities (shell/file/exec) and prompt-injection / tool-poisoning signals — returning a 0-100 trust score, verdict (trusted/review/do-not-trust) and findings. Pass ?target=<mcp-url> to check a specific server (defaults to a live demo server).
Output
Returns a JSON object containing a 0-100 numeric trust score, a verdict string (trusted, review, or do-not-trust), detailed findings covering reachability, HTTPS validation, MCP handshake result, advertised tools inventory, flagged risky capabilities (shell/file/exec), and any detected prompt-injection or tool-poisoning signals.
Example use cases
Pre-connection MCP server safety audit
“I'm about to add a new MCP server at https://tools.somevendor.ai/mcp to my agent stack — can you check if it's safe, tell me its trust score, and flag any shell, file, or exec capabilities before I connect?”
Detecting prompt injection in a third-party MCP tool
“I found an MCP server at https://open-mcp.untrusted-domain.xyz — can you scan it for prompt-injection and tool-poisoning signals and give me a verdict on whether I should trust it?”
Automated vetting of community MCP servers
“We're evaluating a list of community MCP servers and the first one is https://community-tools.mcp-hub.io — run a security check on it and tell me if it passes HTTPS, completes the MCP handshake, and comes back as trusted or do-not-trust.”
Technical details
Endpoint
GEThttps://47620.xyz/x/mcp-trust?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or developer needs to vet an MCP server before connecting to it, especially for third-party or community servers where trustworthiness is unknown. It is the right choice when you need a structured, machine-readable trust verdict with specific risk signals (shell access, prompt injection) rather than a manual or ad-hoc review.
Side effects
- Target MCP server is unreachable — returns low trust score with reachability failure finding
- Target URL is malformed or missing — returns error response
- MCP handshake fails — flagged in findings with reduced trust score
- Payment not included or insufficient — x402 payment required error
- Rate limiting or timeout on slow target servers — may return partial findings
