A persistent codebase memory plugin for AI coding sessions. It stores a project's structure and file summaries in an MCP server, a standard way for tools to provide context to an AI agent, and includes agents and session hooks.

Use it to cache codebase structure and summaries, provide that knowledge through the MCP server, and run the included agents and hooks during sessions.

The stored summaries let sessions query known project information instead of repeatedly reading the same files. This can provide continuity between coding sessions.

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/marcodavidd020/cerebro-code-memory

Made for: Claude Code.

Security

Grade A, and why

cerebro 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. 1 skill, 5 agents, 4 hooks, 1 MCP server travel with it, and installing the plugin installs all of them — 597 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.

cerebro is a plugin published in the GitHub repository marcodavidd020/cerebro-code-memory (6 stars, last pushed 3mo ago), licensed MIT. Its token cost is not measured: this kind of file is read by the harness, not the model. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
