memmesh-plugin

A plugin that gives AI agents persistent memory across sessions through MCP, a standard way for tools to communicate with an agent. It can run locally on SQLite, a small file-based database, without requiring an API key; hosted mode adds prediction and behavior discovery.

In plain words
What is it for?
Use it to provide cross-session memory and a time-aware knowledge graph to an AI agent. Hosted operation can additionally support confidence-rated predictions and finding recurring behavior patterns.
Why use it?
It lets an agent retain facts, preferences, and decisions instead of starting with an empty memory each session. The local-first option keeps the basic memory store on the developer's machine.

Security

Grade A, and why

memmesh-plugin 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.
