Zephex vs Mem0 — different tools, different jobs

Mem0 (and tools like it) help an AI remember things across chats—your preferences, past decisions, sometimes contact-style notes.

Zephex helps an AI work on your codebase—read files, search the repo, check npm packages, map how the app is wired. It is a hosted MCP server with ten engineering tools, not a memory layer.

Many people run both. This page explains which one fixes which problem.

	Mem0 / memory MCP	Zephex
What it is for	Remember facts across sessions	Understand the repo you have open today
Stores	Chat memories & embeddings	Nothing long-term; code handled per request only
Good prompt example	“Remember we use pnpm on this team”	“Run check_package before npm install”
Finds code in your app	Not its main job	find_code, read_code, get_project_context
Catches bad npm packages	No	check_package, audit_package
Same setup for whole team	Usually per user	One API key, same tools in every editor
Typical install	OpenMemory / Mem0 MCP	npx zephex + editor config

How it works

Memory MCP stores and retrieves embeddings or notes when you ask it to remember something. Zephex does not store your repo—each tool call sends the path or query needed for that request, runs on the hosted endpoint, and returns structured code or audit data to the agent.

Technical flow · Blog: memory vs codebase MCP

Step-by-step: try Zephex in 5 minutes

Create an API key at zephex.dev (Free: 300 requests/month).
Add the zephex block to .cursor/mcp.json — MCP server for Cursor.
Quit Cursor fully and reopen.
Confirm 10 tools under Settings → Tools & MCPs.
Ask: “Run get_project_context on this repo.”

Pick Mem0 when…

You want the agent to remember user-specific facts across many projects.
You are building a product that needs long-term customer context.
Your problem sounds like “it forgot what we agreed on,” not “it cannot find AuthService.”

Pick Zephex when…

The agent needs to read or search your actual repository.
You want package checks before npm install.
Your team uses Cursor, Claude Code, and VS Code and you are tired of different MCP setups on every laptop.

Quick Zephex setup (Cursor)

Create an API key at zephex.dev.
Add the zephex block to `.cursor/mcp.json` (see our Cursor guide).
Quit Cursor fully, reopen, confirm 10 tools under Settings → Tools & MCPs.
Ask: “Run get_project_context on this repo.”

Two prompts, side by side

Memory MCP: “Remember: we never force-push to main and we use Conventional Commits.”

Zephex: “Before we bump Stripe, run audit_package from our current version to latest and list breaking changes, then scope_task for the files we must edit.”

Common questions

Can I use Zephex and Mem0 together?

Yes. Mem0 for long-lived preferences. Zephex when the agent needs your real project—files, dependencies, architecture—not last week's chat summary.

Does Zephex replace OpenMemory?

Only if you mainly need code and package intelligence, not chat memory. OpenMemory is for recall across conversations. Zephex is for shipping: audits, search, scoped tasks.

Which should I add first in Cursor?

If the agent keeps guessing your folder layout or installs sketchy packages, add Zephex first. If it forgets team conventions every new chat, add a memory MCP. They solve different headaches.
