An MCP memory server lets AI assistants such as Claude Desktop or Cursor query stored memories through the Model Context Protocol. For work, that means the assistant can see what you decided, what you owe and what you learned, instead of starting from zero each chat. Keep it read-only, local and limited to what the user may see.
What is MCP?
The Model Context Protocol is an open standard for connecting AI applications to tools and data sources. An MCP server exposes tools or resources; an MCP client (an assistant) calls them.
Why assistants need memory
Assistants are good at reasoning and bad at knowing your context. Without memory, you paste the same background into every chat. With a memory server, the assistant can look up:
- Decisions and their reasons
- Open commitments and owners
- Facts about projects, customers and people
- Recent meeting notes
What makes a memory server safe
| Principle | Why |
|---|---|
| Read-only | The assistant cannot change or delete memory |
| Local | Runs on your computer, not exposed to the internet |
| Permission-aware | Returns only what the user is allowed to see |
| Visible | You know which client is connected |
Reattend's MCP server
The Reattend desktop app includes reattend-mcp, a read-only MCP server that Claude Desktop, Cursor and other local MCP clients can use. It runs locally over stdio and reads your own memory stored on your Mac: what you captured, not the organization's shared memory. It offers these tools:
| Tool | What it returns |
|---|---|
search_memories | Memories matching a query |
facts | Facts Reattend has learned, with dates |
open_tasks | Open tasks and commitments |
search_documents | Documents from folders you chose, Notion and connectors |
who_is | What Reattend knows about a person |
recent | Recent memories |
To connect it, open Reattend's Integrations page, find "Reattend inside other tools", copy the configuration it shows, and paste it into your MCP client's configuration (for example, Claude Desktop's config file or Cursor's MCP settings). The server cannot write, change or delete anything.
Example prompts
- "What did we decide about the pricing change last month, and why?"
- "List my open commitments due this week."
- "Summarize what I know about the Acme renewal before my call." (Use your own customer names; this is an example.)
Frequently asked questions
What is an MCP memory server?
A server that exposes stored memories (notes, decisions, facts) to AI assistants through the Model Context Protocol, an open standard for connecting AI applications to tools and data.
Is it safe to give an AI assistant access to work memory?
It can be, if access is read-only, limited to what the user is allowed to see, runs locally where possible, and the user knows which tool is querying it.
Does Reattend have an MCP server?
Yes. The Reattend desktop app includes reattend-mcp, a read-only MCP server that runs locally and lets Claude Desktop, Cursor and other MCP clients search your own memories, facts, open tasks, documents and people on your Mac.
