PopNx MCP 的三大支柱

这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。

它能帮你做什么

我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。

  • 连接方式: 在你的电脑上运行
  • 传输方式: stdio
  • 分类: 搜索与 AI 记忆

安装

选择你使用的 AI 应用,然后复制设置。

安装之前

  • 基础检查:1 项中通过 1 项
  • 在你的电脑上运行,拥有你的用户账户的权限(文件、网络、应用)。
  • 需要你自己填写: MEMORY_PROVIDER, PM_STACK_ROOT

你需要

  • npm已安装 Node.js(用于 npx 命令)

你用的是哪个应用?

在上方选择你的应用。我们会记住它,下次按钮会显示“安装到 …”。

打开 Claude Desktop → Settings → Developer → Edit Config,把下面的内容粘贴到 claude_desktop_config.json

{
  "mcpServers": {
    "openmem": {
      "command": "npx",
      "args": [
        "-y",
        "@bcmyguest/openmem"
      ],
      "env": {
        "MEMORY_PROVIDER": "your-value",
        "PM_STACK_ROOT": "your-value"
      }
    }
  }
}

在终端中运行这条命令

claude mcp add openmem --env MEMORY_PROVIDER=your-value --env PM_STACK_ROOT=your-value -- npx -y @bcmyguest/openmem

运行前请先填写空着的值。

在 Cursor 中打开

或者自己复制设置

粘贴到项目中的 .cursor/mcp.json,或 ~/.cursor/mcp.json

{
  "mcpServers": {
    "openmem": {
      "command": "npx",
      "args": [
        "-y",
        "@bcmyguest/openmem"
      ],
      "env": {
        "MEMORY_PROVIDER": "your-value",
        "PM_STACK_ROOT": "your-value"
      }
    }
  }
}

浏览器会先询问是否打开应用,然后应用会显示设置并请你确认。密钥的值会留空,由你自己填写。

在 VS Code 中打开

或者自己复制设置

粘贴到项目中的 .vscode/mcp.json

{
  "servers": {
    "openmem": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@bcmyguest/openmem"
      ],
      "env": {
        "MEMORY_PROVIDER": "your-value",
        "PM_STACK_ROOT": "your-value"
      }
    }
  }
}

浏览器会先询问是否打开应用,然后应用会显示设置并请你确认。密钥的值会留空,由你自己填写。

这个服务器在你的电脑上运行,而 ChatGPT 只能连接互联网上的服务器。请选择其他应用。

你的选择通过 Cookie 保存在这台设备上,无需账户。

需要你填写的值

  • MEMORY_PROVIDER env
    Active backend: hindsight (default), mem0, or cognee
  • PM_STACK_ROOT env
    OpenMem stack directory (compose project, .env)

这些设置是根据作者在注册中心的条目生成的。如果 README 的写法不同,请以 README 为准。

OpenMem

[!CAUTION]

Context management is leaving OpenMem. Smart compaction, the LiteLLM context proxy, and the OpenCode trim plugin in this repo are deprecated here and moving to [Smarter Compact](https://github.com/bcmyguest/smarter-compact) (docs, npm install -g smarter-compact). Use OpenMem for memory (providers, indexer, memory_* MCP). Existing OpenMem stacks can still enable the compose context-proxy profile; new context work belongs in Smarter Compact.

OpenMem. Pluggable memory providers (Hindsight, mem0, Cognee) and one setup wizard for coding-agent memory — retain, recall, and index your sources.

A. Memory: your sources become memory any agent can query.

B. Context management *(deprecated in OpenMem — use Smarter Compact instead)*: long sessions stay under the limit; nothing is summarized away.

Benchmarks (context — deprecated here): In seed-matched ContextBench log tasks on Haiku 5.5, smart compaction scored 0.469 higher than keep-everything (95% bootstrap interval 0.339–0.578; eight pairs). Methods and charts still live in this repo (redirect · evidence plan); ongoing product docs and install are on Smarter Compact.

Docs: bcmyguest.github.io/openmem/

MCP: npx -y -p @bcmyguest/openmem openmem-mcp (after the wizard — it needs a running provider)

Start here: Concepts · Quickstart · Compatibility · Development (clone, tests, prek)

Quickstart

StepCommand
1. Wizardnpx @bcmyguest/openmem setup
2. Checknpx @bcmyguest/openmem doctor
3. Coding agentsnpx @bcmyguest/openmem install-coding-agent --yes

From a git clone: Development guide (npm install, npm run setup, tests, prek).

Needs (wizard): Docker Compose v2, Node ≥ 24, and an LLM route for Hindsight — see Quickstart.

Later: npx @bcmyguest/openmem up / down / switch --yes / doctor.

Wizard dry-run (what first setup plans — no writes):

Native compaction replaces history with an LLM summary, so exact values can be lost; smart compaction keeps every turn verbatim and searchable. Context trimming in OpenMem is deprecated — use Smarter Compact (smarter-compact enable). Legacy stack path: context proxy redirect. See architecture for memory runtime paths and provider-specific behavior.

Providers and portability

  • Providers — Provider status lists every provider and its support level from the manifests. Contributor details: adding a provider.
  • MCP — unified memory_* plus optional native/NotebookLM servers: MCP setup.
  • Context management (deprecated in OpenMem) — moved to Smarter Compact; OpenMem page is a redirect.
  • Portable memory — memory_export / memory_import speak PMM: Portable memory.
  • Switch — npx @bcmyguest/openmem switch does not migrate data by itself; export/import (or re-index) moves content.

Compose runs the shared indexer and the services required by the selected provider. Hindsight uses litellm and hindsight (127.0.0.1:8888); mem0 and Cognee use their own APIs and do not include LiteLLM by default. LiteLLM can also be added for memory_reflect synthesis on mem0/Cognee, or to host the optional context proxy's pre-call hook. See Architecture for runtime paths.

Inspiration and related

OpenMem is not affiliated with these projects; they shape the problem or the pattern.

[OpenFeature](https://openfeature.dev/)Inspiration for a vendor-agnostic interface + pluggable providers (there: feature flags; here: coding-agent memory).
[mise](https://mise.jdx.dev/) / [asdf](https://asdf-vm.com/)One CLI over many backends; declarative config and tasks without replacing each tool’s own settings.
[LiteLLM](https://github.com/BerriAI/litellm)Model proxy used on Hindsight stacks; its pre-call hook hosts the context proxy.
[Hindsight coding agents](https://www.npmjs.com/package/@vectorize-io/hindsight-coding-agents)Reference implementation for knowledge pages, initiative capture and ingest status; OpenMem's hooks replace it in openmem mode.
[Mainplane](https://github.com/mainplane-ai/mainplane)Inspiration for smart compaction: continue in a fresh context with a pointer to the saved transcript and retrieve as you go, instead of an LLM summary.
[Letta](https://www.letta.com/) / [MemGPT](https://arxiv.org/abs/2310.08560)Inspiration for smart compaction: evicted turns kept verbatim in searchable recall storage the agent pages back with tools, and file-style search over the transcript (74.0% on LoCoMo). OpenMem does this in a proxy and an MCP server, so no Letta server is needed.
[rtk](https://github.com/rtk-ai/rtk)Compresses shell command output before the agent sees it; install-coding-agent runs rtk init when it is installed. Inspired the context proxy's compression of large tool results (reimplemented, not bundled).
[opencode-clm](https://github.com/bcmyguest/opencode-clm)OpenCode plugin for Context Language Models: the model edits a file mirror of its own context. Same goal as smart compaction, with the model doing the trimming (comparison).
[Meridian](https://github.com/rynfar/meridian)Bridges a Claude subscription to an Anthropic-compatible API; optional Hindsight model backend (guide).
[OpenCode](https://opencode.ai/) / [Claude Code hooks](https://code.claude.com/docs/en/hooks) / [Codex hooks](https://developers.openai.com/codex/hooks)The agent hook and plugin APIs OpenMem translates between (compatibility).

Research notes and benchmark results for the context proxy: Context research.

More setup analogues: Pluggable memory providers.

Formerly personal-memory. Use the openmem CLI and MCP server name; installers drop the old personal-memory MCP entry.
