What is the Memory Box MCP server?

Enables saving, searching, and formatting memories with semantic understanding directly from Cline and Claude Desktop using a Memory Box instance. Exposed over MCP by the memory box mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

  • Save Memories — Save formatted memories to your Memory Box with source information and metadata
  • Search Memories — Search your memories using semantic search with pagination and date sorting
  • Retrieve Memories — Get all memories or memories from specific buckets
  • Bucket Management — Create and delete buckets for organizing memories
  • Memory Management — Update or delete existing memories
  • Find Related Memories — Discover semantically similar memories

Configuration

You will need 4 environment variables: MEMORY_BOX_API_URL, MEMORY_BOX_TOKEN, DEFAULT_BUCKET, SYSTEM_PROMPT. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

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.

When to reach for it

Among the knowledge and memory 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. It is maintained by amotivv; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Memory Box's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Caveats

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the memory box mcp server does with a few real requests.
