An MCP service for shared, governed long-term memory between AI agents, tools, and sessions. MCP is a standard way for an AI client to call external tools and services.

Use it to connect the xmemo memory service through its local npm client and required environment variables.

It provides a shared place for agents to retain information beyond one conversation, subject to the service’s configuration and governance.

xmemo — MCP server by yonro

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/yonro/memory-os-cli

Made for: Claude Code, Codex, Cursor, Gemini CLI, OpenCode.

Security

Grade A, and why

xmemo scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

xmemo is an MCP server published in the GitHub repository yonro/memory-os-cli (12 stars, last pushed 2d ago), licensed MIT. Its token cost is not measured: an MCP server costs its tool schemas, not its config file. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
