Install with agentmods

npx agentmods add mcp/janyork/llm-wiki-cli/claude-lwc-lwc

Installing this writes the configuration, not the program: `lwc` has to be on your PATH already, or the server will not start.

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/JanYork/llm-wiki-cli

Installing this writes the configuration, not the program: `lwc` has to be on your PATH already, or the server will not start.

Made for: Claude Code.

Or install claude-lwc, the plugin that ships this one along with the rest of its 8 skills, 7 hooks, 1 MCP server.

Security

Grade A, and why

lwc 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 2mo 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.

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.
