The 15 best memory MCP servers

The 15 memory MCP servers worth your time, out of 755 we track - actively maintained, with real adoption, ranked on monthly installs, GitHub stars, and commit recency. Checked nightly.

Memory MCP servers persist facts, notes, and retrieval indexes across agent sessions. Differentiate on storage backend, retrieval quality controls, and whether memory is personal, project-scoped, or shared.

How to choose between them

Codebase Memory tops the list - the most installs (39,800 last month) and actively maintained. All 15 run locally as stdio servers. 12 document no required env vars - paste the config and go; the others need env vars set first (each page lists exactly which). Where we've compared two of these head-to-head, the comparison is linked on each one's page.

How this list is ranked

Ranked from live registry + GitHub data: monthly installs (npm/PyPI), GitHub stars, and commit recency - recomputed nightly. No pay-to-rank, ever. The 15 above lead the full list of 257, all of which you can see on this page. The other 498 we track have stopped being maintained, or nobody is using them yet. Full recipe: how we verify.
