Overview

Description from the maker (original English)

Local-first project memory and mistake-prevention guardrails for AI coding agents.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Developer tools

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "memini": {
      "command": "npx",
      "args": [
        "-y",
        "memini",
        "mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add memini -- npx -y memini mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "memini": {
      "command": "npx",
      "args": [
        "-y",
        "memini",
        "mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "memini": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "memini",
        "mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Common questions

Is Memini safe?

It passed 1 of 1 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?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.4.0) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

In the same category: GitHub, Desktop Commander, Cloudflare MCP

memini

Never the same mistake twice. Mistake-prevention guardrails and persistent project memory for AI coding agents.

AI coding agents are stateless: every session starts with amnesia. The agent that broke your build editing vercel.json on Monday will happily try the exact same edit on Thursday. memini gives each repo a persistent memory of failed attempts, fragile files, decisions, and deployment rules — and *force-feeds* the relevant warning to the agent at the moment it's about to repeat history.

Not a notebook the agent may choose to read. A guardrail it can't skip.

How it works

  1. Memories live in your repo — a .memini/ folder with a local SQLite index and human-readable, PR-reviewable markdown views. Local-first: nothing leaves your machine.
  2. Hooks enforce guardrails — when the agent tries to edit a file with recorded risks, the edit is intercepted *before it happens* and the recorded lesson is injected:

[WARNING] Editing vercel.json broke the build (recorded 2026-07-03) — Tried changing buildCommand; deploy failed. Actual fix: move checkout server-side and set VITE_STRIPE_USE_SERVER=true.

  • warn severity: the agent is warned once per session, then may proceed.
  • block severity: the edit is always denied until a human archives the memory.
  1. Session start injects a digest of the most important memories (severity-first, token-budgeted).
  2. MCP tools let the agent record what it learns: remember_failed_attempt, remember_fragile_file, remember_decision, end_session_summary, plus recall_project_context and check_before_editing.
  3. Git-aware staleness — memories hash the files they reference; pm stale flags memories whose evidence has changed, and stale memories stop firing guardrails until re-verified.

Quickstart (90 seconds)

cd your-repo

npx -y memini init # creates .memini/ + installs Claude Code hooks

record your first guardrail

npx -y memini remember failed_attempt \ "Editing vercel.json broke the build" \ -b "Tried changing buildCommand; deploy failed. Fix: move checkout server-side." \ --file vercel.json --severity warn

That's it. Next time any Claude Code session in this repo tries to edit vercel.json, it gets the warning first.

Cursor, Windsurf, and other MCP clients:

claude mcp add memini -- npx -y memini mcp   # Claude Code MCP

npx -y memini install-mcp --write cursor # Cursor: MCP + rule + enforced preToolUse hook npx -y memini install-copilot # GitHub Copilot: enforced preToolUse hook (.github/hooks) npx -y memini install-mcp # print generic MCP config

Enforcement is a chain of gates, and memini covers several:

  • Before the edit — the edit to a guardrailed file is blocked before it happens. block → denied, warn → the user is prompted with the recorded history. Supported on:
  • Claude Code — pm init installs it
  • Cursor (1.7+) — pm install-mcp --write cursor
  • GitHub Copilot — CLI, cloud coding agent, and VS Code agent mode (preview) — pm install-copilot
  • Before the commit — every tool — a git pre-commit guardrail blocks a commit that touches a block-severity file, no matter which IDE or agent made the edit (Windsurf, Cline, a human…). Installed by pm init (or pm install-hooks --git). Fails open; overridable with git commit --no-verify.
  • Advisory — any MCP client — the check_before_editing / recall_project_context tools, plus an always-applied Cursor rule steering the agent to use them.

Keeping memory useful over time

A memory tool is only as good as what's in it, and it rots if left alone. memini keeps it healthy:

  • Auto-capture — a Claude Code session-end hook nudges the agent to record durable lessons (a fix that worked, a fragile file, a failed approach) when a session actually changed files, so you don't have to remember to pm remember. It stays silent on idle sessions.
  • Usefulness tracking — every time a guardrail actually fires, memini counts it. pm stats shows which memories are pulling their weight and which have never fired.
  • `pm review` — flags near-duplicates, contradictory guardrails on the same file, and dormant guardrails that have never fired long after creation. All local heuristics, no LLM — you decide what to keep, merge, or archive.
  • Git-aware staleness — memories hash the files they reference; when the code changes, the memory is flagged and stops firing until re-verified (pm stale / pm verify).

CLI

CommandWhat it does
pm initSet up .memini/, gitignore, and hooks
`pm remember [-b body] [--file f...] [--severity warn\block]`Record a memory
pm recall [query] [--file f] [--digest]Search memories / preview the agent digest
pm check Guardrail check (exit 1 if risks recorded) — usable in CI
pm list / show / archive / approve Manage memories
pm statsWhat your memory is doing — guardrail fires, coverage, staleness
pm reviewSurface quality issues: duplicates, contradictions, dormant guardrails
pm stale / pm verify Detect and re-verify outdated memories
pm mcpRun the MCP server (stdio)
pm doctorDiagnose setup

Memory types: decision, failed_attempt, fragile_file, architecture, deployment, client_preference, session_summary.

Scopes: sharing rules across repos

Some lessons are project-specific; some apply to every repo on your machine that belongs to the same org or client. memini has three scopes:

ScopeWhere it livesUse it for
project (default) /.memini/this repo's failed fixes, fragile files, decisions
workspace.memini/ in a parent folder of your reposorg/client conventions shared by every repo under that folder
user~/.memini/personal rules that follow you everywhere
cd ~/work/acme && pm init --workspace     # one-time: workspace store covering ~/work/acme/*

from inside any repo under ~/work/acme:

pm remember deployment "DB connections must use org OAuth, never PATs" \ --file "databricks.yml" --severity warn --scope workspace

pm promote --workspace # lift a project lesson that turned out to be org-wide

Every repo under the workspace folder — including ones you create later — gets those guardrails automatically. Resolution walks up the directory tree, like .gitconfig or ESLint configs. Workspace/user file guardrails match by glob (vercel.json matches any repo's vercel.json; config/**/*.yml works too), and wider-scope memories only fire when human-verified — agents can propose memories to project scope only, so a prompt-injected agent can't plant rules that spread across repos. pm doctor shows which scopes are active.

Design principles

  • Enforced, not advisory. MCP memory tools are optional for the agent; hooks are not. The guardrail path works even if the agent never thinks to check its memory.
  • Human-readable, PR-able. Every memory renders to markdown under .memini/ that your team reviews like any other change.
  • Git-linked evidence. Memories record the branch, commit, and file hashes they were born from, so claims are verifiable and staleness is detectable.
  • Local-first. SQLite + markdown in your repo. No accounts, no cloud, no telemetry. Secrets are auto-redacted from memory bodies before they're stored.
  • Cross-tool. Core is a CLI + files; Claude Code hooks and MCP are thin adapters.

Security

Local-first by design: no server, no account, no telemetry. Secrets are auto-redacted before storage, file references are contained to the repo, and injected memory text is size-capped and framed as data. See SECURITY.md for the full threat model — including the honest limitations (guardrails intercept edit tools, not arbitrary shell; warn is advisory, block is not).

Status

Early (v0.1). Team sync — shared memory across your whole team, with a review workflow — is on the roadmap. Feedback and issues welcome.
