A cloud notepad your LLM can write to.

When you're cranking with Claude or Cursor and it spits out a plan, a draft, a summary, and you want that thing out of the chat and onto a link you can send someone. Not a Notion page. Not a file on your laptop. A memo.

One markdown doc, three unguessable links: edit, comment, read-only. Share whichever fits.

Anonymous-first. No signup to make one.
LLM-native. MCP in, markdown out. Your agent creates and keeps editing; you and teammates edit alongside in the browser, realtime.
Ephemeral by default. 30 days, unless you claim it to a (free) account. Keep forever for a few bucks.

Shape of it: an evolved notepad. Quick, shareable, linked to your agent, ephemeral unless kept.

Field Memo for agents

Field Memo is a shareable markdown notepad. Each memo has an unguessable URL of the form https://my.fieldmemo.io/m/<id>?k=<key>, where the key encodes an edit, comment, or read-only role. Field Memo exposes a Model Context Protocol server at https://mcp.fieldmemo.io/mcp (Streamable HTTP, MCP spec 2025-03-26). Creating, reading, and editing memos through the MCP is anonymous and free; account-scoped tools (list_my_memos, delete_memo, claim_memo) prompt OAuth on first use.

Install commands for common clients are listed at https://fieldmemo.io/connect — for Claude Code, claude mcp add --transport http fieldmemo https://mcp.fieldmemo.io/mcp; for Codex, codex mcp add fieldmemo --url https://mcp.fieldmemo.io/mcp. A machine-readable summary of this site is at https://fieldmemo.io/llms.txt.
