Memtrust MCP Server

Agent memory backends each publish their own benchmark numbers, on different tests, measured different ways. memtrust runs the same evals against all four and publishes the raw logs. Run against the vendors, not by them. It runs locally over stdio via the published package.

People who work with agent memory, benchmark and contradiction detection and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Memtrust

before you install - you'll need

Set MEM0_API_KEY, ZEP_API_KEY, OPENVIKING_API_KEY, MEMPALACE_STORAGE_PATH, MEMTRUST_JUDGE_API_KEY before connecting.

Claude Code

claude mcp add rudrendupaul-memtrust -- uvx memtrust-cli

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "rudrendupaul-memtrust": {
      "command": "uvx",
      "args": [
        "memtrust-cli"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license Apache-2.0 - declared in the repository

pypi package memtrust-cli - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.RudrenduPaul is GitHub-verified and matches the repo owner

03 · What Memtrust can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

Limitations (from the README)

[!WARNING] A real bug this run surfaced in mem0ai itself, not in memtrust: a fresh mem0ai==2.0.12 install with nothing but OPENAI_API_KEY set fails every single LLM-based extraction call, out of the box, for anyone.

06 · Memtrust FAQ

What is Memtrust?

Is Memtrust still maintained?

Yes - as of 2026-09-18, its last commit was 2026-08-25 and it shipped 5 releases in the last 90 days. We re-verify nightly.

How do I install Memtrust?

Run `uvx memtrust-cli`. The README documents 5 environment variables (MEM0_API_KEY, ZEP_API_KEY, OPENVIKING_API_KEY…) to set first. Set MEM0_API_KEY, ZEP_API_KEY, OPENVIKING_API_KEY, MEMPALACE_STORAGE_PATH, MEMTRUST_JUDGE_API_KEY before connecting. You can also paste the ready-made client config above.

Does Memtrust run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
