Everythings for Claude Code

Everythings is a collaborative workspace app for notes, lists, and items ("things"). This plugin gives Claude Code three powers:

• MCP tools in every project — Claude can search, read, and (with a write-scoped sign-in) create and edit your things from any session. When it needs a decision while you are away, it can ask: the question reaches your phone through the Everythings app, and Claude picks up your answer on its next run.
• /things: a pane in Claude Code that draws your workspaces and things beside the transcript and opens each thing as the agent writes it. Press a mark to add or remove your own, or leave a comment, without leaving the session. It needs a Claude Code build that runs plugin hook modules (the terminal or the desktop Code tab).
• /everythings:panel — your live panel — publishes a private claude.ai artifact showing your workspaces and things, with content, marks, comments, and a follow mode that auto-opens things as an agent creates them. Ask an agent to plan a trip and watch the plan assemble itself.

Install

claude plugin marketplace add bbabkin/everythings-claude

claude plugin install everythings@everythings-claude

(or interactively: /plugin marketplace add bbabkin/everythings-claude, then pick everythings under /plugin install.)

Setup

1. An account at everythings.app (free tier works).
2. On first MCP use, Claude Code walks you through the OAuth sign-in to https://www.everythings.app/api/mcp.
3. For the panel: in claude.ai Settings → Connectors, find Everythings in the connector directory and connect it (or add the same URL as a custom connector; keep the name Everythings), then run /everythings:panel.

Your panel is a private artifact on your claude.ai account — every user publishes their own; nothing is shared unless you share it.

Sign-in, credentials, and data

• The plugin holds no credentials and never asks you for one. It reads no environment variables, no files, and no tokens from your machine, and it has no shell scripts or local servers.
• The /things pane is a hooks module (hooks/register.tsx) that runs inside Claude Code. It watches one thing: the Everythings tool calls of the session it runs in, so it can draw what they carried. Its own calls go to the same Everythings MCP server through Claude Code, on the sign-in Claude Code already holds. It writes only when you act: your mark when you press a mark, your comment when you submit one, and one prompt in your name when you press "Ask Claude to open it". It keeps one flag in Claude Code's plugin storage (that you dismissed a permissions note), copies permission rule text to the clipboard when you press Copy, and makes no network requests of its own.
• Sign-in is OAuth 2.1 with PKCE against https://www.everythings.app/api/mcp. Claude Code runs that flow and stores the resulting token itself. For the panel, the claude.ai connector you connect runs its own OAuth sign-in and keeps its own token. The skill and the panel page never see either one.
• Your workspaces, things, marks, and comments travel only between Claude and www.everythings.app, through the MCP tools that you or Claude call. The panel page makes no network requests of its own: claude.ai relays its tool calls through your connector. It keeps one value in its browser storage, the id of the workspace you last opened, so it reopens there.
• Privacy policy: everythings.app/privacy. Terms: everythings.app/terms.

Using Cowork?

The MCP tools work there — a Cowork agent can research and file everything into your workspaces. Publishing the panel needs Claude Code (CLI or web) or claude.ai, so run /everythings:panel once there, then keep the panel open in a browser beside Cowork: with follow mode armed it opens each thing as the Cowork agent writes it.

Notes

• Under auto permission mode Claude Code can refuse the pane's own reads and writes. The pane then draws from what the agent's calls already carried and shows a note with the exact mcp__<server>__<tool> allow rules to add to your permission settings, with a Copy button.
• A mark or comment you make from the pane is yours, and it carries the agent's label, because the call rides the agent's sign-in.
• The panel is read-only and refreshes on a ~30 second poll (the connector platform's floor). It shows which things an agent wrote and any question it is waiting on you for, but never answers one: answer in the app, or tell the agent in the chat.
• Panel improvements ship with plugin updates; running /everythings:panel after an update republishes the new page to your same URL.
