A research plugin built around nab MCP tools and research workflows for web pages, the Wayback Machine, the Internet Archive, and O’Reilly resources. The Wayback Machine is a service that stores older copies of web pages.

Use it to fetch and research URLs, inspect archived pages, work with Internet Archive material, and follow O’Reilly research workflows.

It organizes several research and archive tasks, including sources that may require authentication, in one agent workflow.

nab — Plugin for Claude Code by MikkoParkkola

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/MikkoParkkola/nab

Made for: Claude Code.

Security

Grade A, and why

nab scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Contents

What it installs

The manifest is a name and a version. 6 skills, 1 command, 1 hook, 1 MCP server travel with it, and installing the plugin installs all of them — 657 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
