Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install mcp-server-security

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent reviews authentication, permissions, quotas and input validation on your MCP server. You get a list of flaws to fix and the controls to put in place.
