What is the Mem MCP server?

A portable, long-term agentic memory MCP server — a thumb drive for your AI context. The mem mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 14 defined tools rather than through you.

Adding it to your client

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

Its toolset

Everything the assistant can do here goes through one of these:

  • save_memory — Save a fact/preference/decision/task/reference, optionally linked to entities
  • search_memory — Semantic (vector) search over memories
  • save_episode — Record a raw interaction/event that memories can be derived from
  • list_episodes — List recorded episodes, filterable by time range/source
  • save_skill — Save a reusable procedure, optionally linked to entities
  • search_skills — Semantic (vector) search over skills, by task/situation
  • list_skills — List saved skills, filterable by tag/source
  • get_skill — Look up a skill by exact name or id
  • forget_skill — Soft-archive (default) or permanently delete a skill
  • save_adr — Record an architectural decision, optionally superseding an earlier one
  • search_adrs — Semantic (vector) search over ADRs, by problem or area
  • list_adrs — List the ADR log, filterable by status/tag/source

Caveats

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Mem.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the mem mcp server does with a few real requests.

When to reach for it

Among the planning and project tracking options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Mem's toolset — save_memory, search_memory, save_episode and 11 more — is a fair guide to whether it matches your workflow. It is maintained by rsl-innovation; worth a glance at recent repository activity before you build anything load-bearing on it.

  • Use Mem to save episode.

Frequently asked questions

It connects Mem to MCP-compatible AI assistants such as Claude and Cursor, exposing 14 tools (save_memory, search_memory, save_episode, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Mem directly.
