What tools does collective-memory expose?

This server runs as a local package. We only query remote servers for their tool list — asking this one would mean executing it, so its tools are listed in the documentation below.

What the code can do

Read from the published package source — never executed. Parsed 7 of 7 source files.

This server can make network requests and read your environment variables.

How it was published

No provenance attestation — there is nothing linking this published artifact to a specific source commit.
1 npm maintainer — a single point of compromise · last published by hustada.

Maintainer of this package and think something here is wrong? Tell us and we'll correct it.

Before you install

Signals gathered from the source repo and package registry — not a safety verdict.

What it can reach

Runs code on your machine — Executes as a local process with your user's permissions, including filesystem access.
Downloads at launch — The package is fetched from its registry each run unless you pin a version.

Last commit 5 months ago — Actively maintained.
0 GitHub stars — Very little community usage so far.

Documentation

Full README

Collective Memory

MCP server for persistent, semantic memory across AI sessions. Store context, decisions, and learnings — recall them later with natural language search.

Why

AI assistants forget everything between sessions. Collective Memory fixes that. Store what matters, search by meaning, build context that compounds.

Features

Semantic search — Find memories by meaning, not keywords (OpenAI embeddings + LanceDB)
Automatic deduplication — Won't store near-duplicates (>95% similarity)
Project scoping — Organize memories by project
Type classification — Categorize as decision, milestone, context, learning, or session_summary
Zero config storage — Embedded vector database, no server required

Installation

bash

npm install -g collective-memory

Or clone and build:

bash

git clone https://github.com/Hustada/collective-memory.git
cd collective-memory
npm install
npm run build

Setup

1. Get an OpenAI API key

Required for embeddings. Get one at platform.openai.com.

2. Add to Claude Code
