Mnemograph MCP Server

local only

Mnemograph runs on your own machine — the client starts it, so there is no endpoint to ping. 148 installs a week from pypi. Last commit 14 Feb 2026.

A tool parameter reaches a dangerous call

A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

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.

        subprocess.run(["git", "add", str(relative_path)], cwd=engine._git_root, capture_output=True)
    <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.

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 mnemograph -- uvx mnemograph
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "mnemograph": {
      "args": [
        "mnemograph"
      ],
      "command": "uvx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.mnemograph]
command = "uvx"
args = ["mnemograph"]
.cursor/mcp.json
{
  "mcpServers": {
    "mnemograph": {
      "args": [
        "mnemograph"
      ],
      "command": "uvx"
    }
  }
}
.vscode/mcp.json
{
  "mcpServers": {
    "mnemograph": {
      "args": [
        "mnemograph"
      ],
      "command": "uvx"
    }
  }
}

This one needs environment variables set before it will start: MEMORY_PATH (Path to memory storage directory). The author declared them in the registry entry; get the values from the project itself.

Mnemograph — questions

Answers built from our own checks of this server.

Why is there no uptime for Mnemograph?
Mnemograph 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 pypi package mnemograph was installed 148 times last week.
How do I connect Mnemograph?
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 mnemograph straight from pypi; nothing to host, nothing to sign up for.
How many people use Mnemograph?
The pypi package mnemograph was installed 148 times in the last week. Week over week that is -24%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Mnemograph open source?
Yes — it is published under the MIT licence, written in Python and 2 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.
