What would you like to share?

Hi all 👋 Sharing a remote MCP server I've been building: agentage Memory.

The gap I kept hitting: every assistant now has its own memory (ChatGPT memory, Claude memory, …), but it's siloed per-vendor, you can't see the raw data, and you can't move it between tools. I wanted one memory that any AI can read and write - and that I actually own.

What it is: a hosted, remote MCP server that exposes a single personal memory as plain Markdown files. Anything that speaks MCP can read/write it, and the same notes are mirrored locally as .md you can open in your editor or export anytime.

Server details

• Transport: Streamable HTTP
• Endpoint: https://memory.agentage.io/mcp
• Auth: OAuth 2.1 + PKCE + Dynamic Client Registration — no manual client setup; the client registers itself and you sign in once
• Tools (6):
  • memory__search - full-text search across your memory
  • memory__list - folder-tree outline of what's stored
  • memory__read - read a note (raw Markdown)
  • memory__write - create / overwrite a note
  • memory__edit - in-place edits (replace / append)
  • memory__delete - remove a note

Connect (any remote-MCP client, e.g. Claude Code):

{
  "mcpServers": {
    "agentage-memory": {
      "type": "http",
      "url": "https://memory.agentage.io/mcp"
    }
  }
}

The first call kicks off the OAuth flow via DCR; after sign-in the tools show up.

What's a bit different from other memory servers

• Files-first — the source of truth is plain Markdown you own, not an opaque vector DB. Export anytime.
• Cross-vendor — one memory shared across whatever MCP clients you use, instead of N vendor silos.
• Remote + real auth — full OAuth 2.1 + PKCE + DCR rather than a local stdio stub or an API key pasted into a config file.

Would love feedback from this community — especially on the OAuth/DCR flow and the tool surface (naming, the search/list split, anything you'd expect from a memory server that's missing). Happy to dig into any of the design choices. 🙏
