Engram vs Notion and Mem hosted MCP

What is the difference?

Notion and Mem both run first-party hosted MCP servers, at mcp.notion.com and mcp.mem.ai. Connect over OAuth and your AI can search and edit your workspace. No plugin, no config file, included in the subscription you already pay for.

Engram does the same job for a folder of markdown files you own.

So the MCP part is not the difference. Both sides have a hosted endpoint with OAuth. The difference is what sits behind it: their database, or your files.

Where they win

Be honest with yourself about scale here. Notion is a much larger product than Engram and a lot of what it does we do not attempt.

• Notion has databases, views, permissions, comments, real-time collaboration, templates, and a decade of polish. If your team runs on it, the MCP server means your AI now reaches all of that.
• Mem is purpose-built around capture and recall and is good at it.
• Both are included. No separate product to buy or connect.
• Both are less setup than Engram, because your content is already in them.

If you already live in Notion and like it, its MCP server is the correct answer and this page is not trying to talk you out of it.

Side by side

	Notion / Mem MCP	Engram
Hosted MCP endpoint	Yes	Yes
OAuth	Yes	Yes, 2.1 with Dynamic Client Registration
What your knowledge is stored as	Their database	Markdown files on your disk
Readable without the vendor	Export, with fidelity loss	cat a file
Works offline, in another editor	No	Yes
Self-host	No	Yes, whole stack
Collaboration and permissions	Yes (Notion)	No
Databases, views, templates	Yes (Notion)	No
Vendor can change terms on your archive	Yes	Your copy is already on your disk

The part that actually matters

Every vendor with a hosted note product will ship an MCP server, because it is not hard and users are asking. Within a year, “my AI can reach my notes” will be true of nearly every notes app. It will not be a differentiator.

What will still differ is what happens when you want to leave, or when a price changes, or when a feature you depend on gets deprecated. At that point the question is whether your knowledge is in a format you can read without the company that stored it.

Notion exports. Most tools do. The question is what survives the trip: nested databases, relations, embeds, and view configuration are structure that a markdown export flattens. That is not Notion being hostile, it is what happens when a rich data model meets a plain one.

Engram’s answer is to not have the problem. The canonical copy is already markdown on your disk. Engram syncs it, indexes it, and serves it. If Engram disappears tomorrow, the folder still opens in Obsidian, in VS Code, in cat.

What Engram gives up to get that

A plain folder of markdown cannot do what a database does.

• No relations, rollups, or database views.
• No shared workspaces, permissions, or comments.
• No real-time collaboration.

These are not on a roadmap we are hiding from you. Some of them are fundamentally at odds with “it is just files,” and we would rather be excellent at one shape than mediocre at both.

Which should you pick?

Notion or Mem, if your work is already there, you need collaboration and structured databases, and portability is a someday concern rather than a today one.

Engram, if you think in documents rather than database rows, you want the canonical copy on your own disk, and you want the option to run the whole stack yourself.

Summary

Both give your AI a hosted endpoint into your knowledge. One stores that knowledge in a product, the other in a folder. Pick based on what you want to be true in three years, not on which MCP server works today, because by then they both will.
