Best tools
The best MCP memory server is portable, authenticated, and explicit
MCP gives agents a standard way to call tools. A memory server on MCP should preserve useful context without turning private user data into public crawler content.

What to check before adopting an MCP memory server
A memory server should make the authentication boundary, tool surface, and data model understandable before a user connects it to an agent.
- Streamable HTTP or another supported MCP transport
- OAuth or scoped bearer-token access for private memory
- Separate read, write, TODO, ledger, and deletion semantics where applicable
- Safe public discovery that advertises the server without leaking user records
XMemo MCP fit
XMemo exposes a hosted MCP endpoint at https://xmemo.dev/mcp and keeps private memory behind authenticated user consent.
- Works as a remote MCP memory layer for compatible clients
- Supports attribution headers so memory records can show which agent or device provided context
- Keeps SEO, llms.txt, and agent discovery files limited to public product metadata
Supported client patterns
| Client | Connection path | Notes |
|---|---|---|
| GitHub Copilot / VS Code MCP | Use the hosted MCP URL and OAuth flow where supported | Good fit for repository conventions and coding-agent memory |
| Claude-compatible MCP | Connect through a remote MCP connector or developer workflow | Use for portable memory that should outlive one Claude conversation |
| ChatGPT-compatible MCP/App flows | Authorize XMemo when the client exposes an MCP or app integration path | Use alongside built-in memory when context should also work elsewhere |
| Gemini CLI, Cursor, Codex, custom agents | Configure https://xmemo.dev/mcp with user-scoped credentials | Use when the client can call remote MCP tools or the XMemo API |
Frequently asked questions
What is an MCP memory server?
An MCP memory server is a Model Context Protocol server that exposes memory tools an authorized AI client can call to save, recall, update, or manage user context.
Does MCP make memory public?
No. MCP is a tool protocol. A well-designed memory server still requires authentication for private memory operations.
Is XMemo remote or local?
The public XMemo service exposes a hosted Streamable HTTP MCP endpoint. Clients can connect remotely with user-scoped authentication.
