Zephex vs OpenMemory — different tools, different jobs

OpenMemory helps an AI remember things across conversations—preferences, notes, and context you want to carry into the next chat.

Zephex helps an AI work on your codebase—search files, read symbols, audit npm packages, map architecture. It is a hosted MCP server with ten engineering tools, not a memory layer.

This page is for developers evaluating an OpenMemory alternative when the real problem is repo layout, dependencies, or supply-chain risk—not forgotten chat facts.

	OpenMemory / memory MCP	Zephex
Primary job	Recall across chats	Understand and change the repo open now
Stores long-term	Embeddings & memory entries	No code storage; per-request processing
Finds AuthService in your app	Not the focus	find_code + read_code
Typosquat check before npm install	No	check_package
Team same tool versions	Often per-user memory	One API key policy + dashboard
Typical Cursor config	OpenMemory MCP entry	npx zephex or HTTPS Bearer
Works without your repo open	Yes (memory only)	Needs path or github: URL for code tools
Best paired with	Zephex for code tasks	OpenMemory for preferences

How it works

Memory MCP writes and reads a memory store. Zephex receives a tool call from your editor, processes the minimum input for that tool, and returns structured results (file lists, search hits, audit reports).

Pick OpenMemory when…

You need persistent user or customer context across many sessions.
Your prompts are about recall: “remember our release process.”
You are not trying to map an unfamiliar monorepo today.

Pick Zephex when…

You need get_project_context on a real tree.
You want check_package before npm install.
Your team uses multiple editors and wants one hosted MCP setup.

Step-by-step: try Zephex in 5 minutes

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

Two prompts, side by side

OpenMemory: “Remember: we always squash-merge feature branches and use UTC in logs.”

Zephex: “Run check_package on the package name the user pasted, then scope_task for upgrading our Stripe integration files.”

Common questions

Should I replace OpenMemory with Zephex?

Only if you mainly need codebase and package tools, not chat recall. Many teams keep OpenMemory (or Mem0) and add Zephex for engineering work.

Does Zephex remember my preferences next week?

No—that is what memory MCP is for. Zephex answers the current task with live project and registry data.

Which do I add first in Cursor?

If the agent cannot find files or installs risky packages, add Zephex first. If it forgets team conventions every new chat, add memory MCP first—or both.
