What it can do

Tool names and descriptions exactly as the server reported them on Nov 11, 2026. The maker wrote them, not us; we show them as plain text.

list_skills
List available defensive security skills, optionally filtered by family or a free-text query (matched against name, description, tags and frameworks).
get_skill
Return a skill's description, frameworks, tags, context and ordered phase ids.
get_skill_phase
Load the methodology content for one phase of a skill. The phase is given as a phase id or as a 0-based index among authored phases.

Common questions

Is Aegis Security Skills safe?

It passed 4 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed 30 days ago, and the latest version (1.5.0) reached the registry 32 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

What can I use instead?

aegis-skills

24 defensive cybersecurity skills in the open Agent Skills format, with a native installer and a read-only MCP server.

Install

npx aegis-skills install --platform claude # or codex, gemini, cursor, vscode, antigravity, all npx aegis-skills install --platform claude --project

Skills go into each tool's own skills folder and the aegis MCP server is registered in its config (the file is backed up first). After an upgrade, installed skills refresh automatically; files you edited are kept as .bak. Opt out with AEGIS_NO_AUTO_REFRESH=1.

Claude Code plugin: /plugin marketplace add drupadsachania/aegis-skills, then /plugin install aegis-skills@aegis-skills.

Commands

install (alias init), uninstall, update, list, mcp. Run aegis --help.

MCP

npx aegis-skills mcp serves list_skills, get_skill and get_skill_phase on stdio. Hosted: https://aegis-skills.vercel.app/api/mcp.

What this plugin runs, sends and fetches

Claude Code plugin (`.mcp.json`): connects to one remote MCP server, https://aegis-skills.vercel.app/api/mcp. It runs no local command. The three tools (list_skills, get_skill, get_skill_phase) are read-only and return fixed public skill text. What is sent is the tool call itself (a skill name, a phase or a search word) and the usual request metadata such as your IP address. The server keeps only an in-memory request counter, makes no model calls and stores nothing. The skills themselves are plain Markdown that your assistant reads locally.
`npx aegis-skills` (the installer and stdio server): runs the pinned npm package aegis-skills. install writes skill files into your tool's skills folder and adds an aegis entry to its MCP config (backed up first). A ledger of what it installed is kept under ~/.aegis (override with AEGIS_HOME). mcp serves the same three read-only tools from the bundled skills on stdio. Neither command makes a network request of its own beyond npm downloading the package.
No telemetry, no analytics and no credentials. Nothing is read from your conversations, memory or uploaded files.

Every skill is for defensive use on systems you own or are explicitly authorized to assess.
