memory is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from 4DA-Systems/4DA. Its token cost is not measured, scanned A, original, no licence file.

A memory service connected through MCP, a standard way for AI assistants to use external tools and data. It runs a Node.js server and requires one environment variable.

In plain words
What is it for?
Use it when a project needs to connect an AI assistant to the configured memory server.
Why use it?
It provides a configured service for storing or retrieving memory, although the description does not specify its exact operations.

MCP server for Claude CodeCodexCursorGemini CLIOpenCode

Written for no agent in particular: it speaks MCP, so any client can run it. Also seen: listed in a Claude config.

One of 4 entries in .mcp.json upstream. Installing this one merges just its entry into your config; the other 3 are separate, each on its own page.

Good fit Use it when a project needs to connect an AI assistant to the configured memory server.

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.

Security

Grade A, and why

memory 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 1mo 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

This page is one entry in a file that holds 4. Installing the file brings all of them; each is measured and scanned on its own page.

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.
