A project-memory plug-in that loads a committed mnema record at the start of a session, applies its write rules, and connects an MCP server so the agent can record work. MCP is a standard way for an agent to connect to external tools or services.

Use it to provide session context from project records, enforce those records during changes, and save the agent's work through the mnema service.

It keeps agreed project notes available without the agent having to ask for them each time. It also prevents writes that conflict with the recorded rules.

mnema — Plugin for Gemini CLI by felipesauer

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/felipesauer/mnema

Made for: Gemini CLI.

Security

Grade A, and why

mnema 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 2d ago.

The scan reads gemini-extension.json. This mod also ships 1 executable file (hooks/mnema.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

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.
