Vets MCP servers, Claude Code skills, or plugins for unsafe behavior like shell execution, secret access, data exfiltration, prompt injection, and remote code before installation, returning a graded verdict with findings.
README
MCPVet MCP server
Vet an MCP server, Claude Code skill, or plugin for unsafe behavior — shell execution, secret access, data exfiltration, prompt injection, remote code — before you install it, right inside your agent.
It's a thin, auditable client: all analysis runs server-side at mcpvet.com. This process holds no credentials, touches no local files, and makes exactly one outbound HTTPS call per scan.
Install (Claude Code)
claude mcp add mcpvet -- npx -y github:LorenzoLombardi111/factory-mcpvet
Or add it to your MCP config manually:
{
"mcpServers": {
"mcpvet": {
"command": "npx",
"args": ["-y", "github:LorenzoLombardi111/factory-mcpvet"]
}
}
}
Use
Ask your agent:
Before I install it, scan
@some/mcp-serverwith MCPVet.
The scan_extension tool accepts:
- a GitHub repo URL —
https://github.com/owner/repo - an npm package name —
@scope/pkg - pasted skill / manifest text
It returns a graded verdict (clean → critical), the flagged findings with file and line, and a shareable report link.
