NeoLi00/memX

English · 中文 · Architecture

---

memX turns completed work into structured, searchable, self-maintained memory, then injects only the evidence an agent needs for the current query. It connects natively to Codex, Claude Code, and OpenClaw, and reaches any MCP-compatible client through the same local memory layer.

Quick start

Requirements: Node.js 22.14+ or Node 24. OpenClaw installs require OpenClaw 2026.3.25+. Python 3 is needed only for the default local embedding runtime.

The README commands use the GitHub package spec. A fresh run pulls current GitHub code, so installs do not wait for an npm publish. To use the npm release channel later, replace github:NeoLi00/memX with @neoli00/memx.

Fill in these values before running a command:

• --llm-provider: the provider adapter memX should call. Choose one of openai-compatible,

anthropic, google, or ollama.

• --llm-base-url: the base URL for that provider. Examples: https://api.openai.com/v1,

https://api.anthropic.com/v1, https://generativelanguage.googleapis.com/v1beta, or http://127.0.0.1:11434 for Ollama.

• --llm-model: the model memX uses for memory compilation, recall planning, and maintenance.

Pick a fast, low-cost model with reliable JSON output.

• --llm-api-key: the API key for the provider. Use --llm-api-key-env PROVIDER_API_KEY if you

want the config to reference an environment variable instead of storing plaintext. For local Ollama, omit the key.

The default embedding setup is local sentence-transformers-local with intfloat/multilingual-e5-small. Add --embedding-provider and --embedding-model only when you want to override that default. Use --dry-run to preview the files and exec-form commands before writing anything.

For Codex and Claude Code, native hooks are the default lifecycle path for automatic recall and turn capture. Quickstart installs the native plugin, writes the shared memX config, starts or refreshes the managed local memX service, and keeps MCP memory tools hidden with --mcp-tools none by default. This prevents duplicate recall/write and prevents the agent from reading audit data as a side channel. Use --mcp-tools full only when you intentionally want the agent to see the complete MCP tool set. Generic MCP quickstart stays full by default because it has no native lifecycle hooks. Default native memories are also host-scoped, so Codex and Claude Code do not share the same local database unless you deliberately override the database path and actor settings.

If http://127.0.0.1:3878 is already used by an unmanaged memX-compatible service, quickstart stops instead of silently reusing it. Stop the old service or pass a free local URL, for example --memx-url http://127.0.0.1:3888.

Claude Code

This installs the shared memX config, a local Claude Code plugin marketplace, native lifecycle hooks, and the managed local memX service in one run.

npx -y -p github:NeoLi00/memX memx quickstart claude-code \
  --llm-provider openai-compatible \
  --llm-base-url https://llm.example.com/v1 \
  --llm-model fast-memory-model \
  --llm-api-key sk-your-provider-key

Codex

This installs the shared memX config, a local Codex plugin marketplace, native lifecycle hooks, and the managed local memX service in one run.

npx -y -p github:NeoLi00/memX memx quickstart codex \
  --llm-provider openai-compatible \
  --llm-base-url https://llm.example.com/v1 \
  --llm-model fast-memory-model \
  --llm-api-key sk-your-provider-key

OpenClaw

npx -y -p github:NeoLi00/memX memx quickstart openclaw \
  --llm-provider openai-compatible \
  --llm-base-url https://llm.example.com/v1 \
  --llm-model fast-memory-model \
  --llm-api-key sk-your-provider-key

Generic MCP

Use this path for MCP clients that do not have a native memX lifecycle adapter. Quickstart writes the shared memX config, starts the managed local memX service, and prints a ready-to-copy MCP server config.

npx -y -p github:NeoLi00/memX memx quickstart mcp \
  --llm-provider openai-compatible \
  --llm-base-url https://llm.example.com/v1 \
  --llm-model fast-memory-model \
  --llm-api-key sk-your-provider-key

Service management

npx -y -p github:NeoLi00/memX memx service status
npx -y -p github:NeoLi00/memX memx service restart
npx -y -p github:NeoLi00/memX memx service stop

Use the same --home, --memx-url, and --memx-secret values that you used during quickstart when you manage a non-default install.

Clean uninstall

Each uninstall command backs up the target config first, then removes only memX-owned entries. Claude Code and Codex cleanup also stop the managed local service, uninstall the native plugin, remove the local marketplace, and delete the generated marketplace snapshot. OpenClaw cleanup also removes stale memx / memory-memx slot, allow, and entry references, then best-effort uninstalls both current and legacy plugin files if OpenClaw can still see them.

npx -y -p github:NeoLi00/memX memx uninstall openclaw
npx -y -p github:NeoLi00/memX memx uninstall codex
npx -y -p github:NeoLi00/memX memx uninstall claude-code

Add --dry-run to preview, or --config /path/to/config when using a non-default config path.

What memX can do

• Remember work over time: project decisions, user preferences, task status, long source

segments, and raw evidence stay linked to the original turn.

• Connect related things: projects, repos, tools, files, resources, blockers, and outcomes can

be represented as entities and graph edges.

• Learn collaboration patterns: repeated evidence can become reusable guidance without losing

its supporting sources.

• Maintain itself: corrections can supersede older facts, stable evidence can be promoted, and

stale task state stops competing with current state.

• Recall compact evidence: facts, events, state, chunks, relationships, resources, and learned

patterns are searched together, then injected as small evidence lines.
