Collective Memory MCP Server

What the code does

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Page loads a third-party script viz/index.html:317
  <script src="https://d3js.org/d3.v7.min.js"></script>

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add collective-memory -- npx -y collective-memory
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "collective-memory": {
      "args": [
        "-y",
        "collective-memory"
      ],
      "command": "npx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.collective-memory]
command = "npx"
args = ["-y", "collective-memory"]
.cursor/mcp.json
{
  "mcpServers": {
    "collective-memory": {
      "args": [
        "-y",
        "collective-memory"
      ],
      "command": "npx"
    }
  }
}
.vscode/mcp.json
{
  "mcpServers": {
    "collective-memory": {
      "args": [
        "-y",
        "collective-memory"
      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: OPENAI_API_KEY (OpenAI API key for generating embeddings). The author declared them in the registry entry; get the values from the project itself.

Collective Memory — questions

Answers built from our own checks of this server.

Why is there no uptime for Collective Memory?
Collective Memory runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package collective-memory was installed 40 times last week.
How do I connect Collective Memory?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls collective-memory straight from npm; nothing to host, nothing to sign up for.
How many people use Collective Memory?
The npm package collective-memory was installed 40 times in the last week. Week over week that is -22%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Collective Memory open source?
Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
