What is the MCP Memory Keeper MCP server?

If you already use MCP Memory Keeper, the mcp memory keeper mcp server is the piece that lets your assistant work with it directly. MCP server for persistent context management in AI coding assistants.

What the server does

A Model Context Protocol (MCP) server that provides persistent context management for Claude AI coding assistants. Never lose context during compaction again! This MCP server helps Claude Code maintain context across sessions, preserving your work history, decisions, and progress.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • Profile — Tools
  • minimal — 8
  • standard — 22
  • full — 38
  • TOOL_PROFILE — Config file has profile?
  • Set — Yes
  • Variable — Description
  • TOOL_PROFILE_CONFIG — Override config file path (default: ~/.mcp-memory-keeper/config.json)
  • Troubleshooting — The Troubleshooting tool exposed by this server

Installation

mcp-memory-keeper on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Credentials and setup notes

Configuration is passed through the environment: TOOL_PROFILE, MCP_MAX_TOKENS, MCP_TOKEN_SAFETY_BUFFER, MCP_MAX_ITEMS, MCP_CHARS_PER_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Where it fits

Plenty of knowledge and memory servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. MCP Memory Keeper's toolset — Profile, minimal, standard and 6 more — is a fair guide to whether it matches your workflow. It is maintained by mkreyman; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 9 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch MCP Memory Keeper.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
