Overview

Description from the maker (original English)

Persistent session memory for Claude Code. Local SQLite, no LLMs, no network.

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: Search & AI memory

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

  • PyPIPython’s uv installed (for the uvx 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": {
    "memex": {
      "command": "uvx",
      "args": [
        "mcp-memex"
      ]
    }
  }
}

Run this in your terminal

claude mcp add memex -- uvx mcp-memex

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "memex": {
      "command": "uvx",
      "args": [
        "mcp-memex"
      ]
    }
  }
}

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": {
    "memex": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "mcp-memex"
      ]
    }
  }
}

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.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

Compared with others in Search & AI memoryi

  • More stars than 0% of the other 5675 servers in this category
  • Published to the registry more recently than 19% of the other 5675 servers in this category
  • Basic checks equal to or better than 100% of the other 5675 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is Memex 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 (0.1.9) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

memex

Every Claude Code session starts without knowing what you built last time - which files you changed, what decisions you made, what broke. You re-explain. Claude re-reads. You start over.

memex keeps a structured log of every session. Claude reads it at the start of the next one.

No cloud. No LLM extraction. No cost per save. Just local SQLite and one command to install.

Install

# with uv

uvx mcp-memex install

with pip

pip install mcp-memex memex install

Restart Claude Code. That's it.

What gets saved

Each entry has structure - not a blob of text:

mem_save(

task="Replaced JWT auth with session cookies", files=["src/auth.py", "src/middleware.py"], decisions=["Session cookies over JWT - simpler, no token refresh needed"], warnings=["Redis required - app won't start without REDIS_URL set"], tags=["auth", "sessions"] )

Claude calls mem_save when it finishes something meaningful. You can also just tell it: *"save what we just did."*

What Claude sees at session start

=== memex: session context (db: my_project.db) ===

--- Recent (2) --- [1] #4 - 2026-06-14T10:32 Task : Replaced JWT auth with session cookies Files : src/auth.py, src/middleware.py Decision : Session cookies over JWT - simpler, no token refresh needed Warning : Redis required - app won't start without REDIS_URL set Tags : auth, sessions

[2] #3 - 2026-06-13T15:10 Task : Added rate limiting to /api/login Files : src/middleware.py Warning : Rate limiter is in-memory per process - resets on restart Tags : auth, rate-limiting

Claude calls mem_load automatically at the start of every session. It returns the most recent entries plus any entries that match what you're working on - by keyword and by file path.

Browse from the terminal

You don't need to be inside Claude to look at your history:

memex status                     # entry count, DB size, top tags

memex list # recent entries for this project memex list --tag auth # filter by tag memex list --since 7d # entries from the last 7 days memex list --since 2026-06-01 --until 2026-06-15 # date range memex search "rate limit" # full-text search memex version # print installed version

Export to markdown

Turn your history into portable, human-browsable notes - one .md file per entry, with [[wikilinks]] connecting related entries and files, plus tags as #hashtags. Works in Obsidian or any tool that understands [[links]]:

memex export ./my-project-notes/

Entries that share a tag or a touched file are cross-linked under a Related section, so you can navigate your project history as a graph.

Six MCP tools

ToolWhat it does
mem_loadCalled at session start - returns recent + relevant entries
mem_saveSaves a structured entry after meaningful work
mem_updatePatches specific fields of an existing entry (keeps id and timestamp)
mem_searchFull-text search across all entries
mem_listLists entries, optionally filtered by tag
mem_deleteRemoves a stale entry by id

Why not just CLAUDE.md?

CLAUDE.md is for static project documentation - architecture, conventions, how to run tests. It doesn't change much and it isn't session-aware.

memex captures what's changing session to session: what you built yesterday, the decision you made this morning, the warning you discovered an hour ago. It's the difference between *"here's the project"* and *"here's what happened last time."*

memex install writes Claude's instructions into .claude/CLAUDE.local.md - a file Claude Code loads automatically without touching your project's own CLAUDE.md.

Memory is scoped per project

Each project gets its own SQLite database at ~/.memex/ .db based on the working directory. Sessions from different projects never mix.

Configuration

Set these in the MCP env block in ~/.claude.json if you need to override defaults:

VariableDefaultDescription
MEMEX_DIR~/.memexWhere DBs are stored
MEMEX_GLOBAL0Set to 1 to share one DB across all projects
MEMEX_RECENT5Max recent entries loaded per session
MEMEX_MATCHED5Max FTS-matched entries loaded per session

Uninstall

memex remove

pip uninstall mcp-memex

Memory DBs are kept at ~/.memex/ - delete that directory manually if you want to wipe everything.

Requirements

  • Python 3.10+
  • mcp package (installed automatically)
  • SQLite with FTS5 (standard since Python 3.8)
  • Claude Code CLI
