In-depth architectural comparison of the Authmcp Gateway and Beelzebub MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Authmcp Gateway
Security · Local stdio
Quality: 55/100 (Good) | Auth: other
Beelzebub
Security · Local stdio
Quality: 51/100 (Good) | Auth: No auth required
Verdict Summary: Choose Authmcp Gateway if you need specialized Security tools running via a local process. Choose Beelzebub if your workspace requires Security integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Authmcp Gateway when:
You need dedicated capabilities in the Security domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: other (Free / Open Source).
Beelzebub is a honeypot framework that lets you build honeypot tools using MCP. Its purpose is to detect prompt injection or malicious agent behavior. The underlying idea is to provide the agent with tools it would never use in its normal work.
