agent-mcp-gateway@0.2.5

CAUTION

Publisher claims: "An MCP gateway that aggregates your existing MCP servers and lets you define which servers and individual tools each agent or subagent can access. Solves Claude Code's MCP context window waste where all tool definitions load upfront instead of being discovered when actually needed." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

Is [email protected] safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-10-26 and scored it 70/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Access to sensitive file paths; Instructs the agent to modify its persistent memory or instruction files; npx invocation of non-well-known package. Summary: no network, touches nothing outside the project, writes no memory.
