## What it does

Seven tools over stdio, all scoped to one three.ws account. The agent pulls the inbound feed — market alerts, sales and earnings, purchase receipts, social mentions, IRL interactions, security notices — marks entries read, and deletes the ones it no longer needs. A separate pair of tools covers the delivery matrix: which channels (`in_app`, `push`, `email`, `telegram`) carry each event category to the owner. Two more register and drop Web Push devices from a browser `PushSubscription`.

Every call goes to the live three.ws API. The server authenticates with `THREE_WS_API_KEY` or an OAuth token, sends it as `Bearer`, and resolves the owning account per request. Nothing is signed locally and no other secret is kept. You need Node 20+ and a key; without the key the server cannot authenticate. Two runtime dependencies: `@modelcontextprotocol/sdk` and `zod`.

Deleting a notification and unregistering a device carry destructive annotations, so clients that honour tool annotations will ask before running them. Marking read and patching preferences are idempotent — a repeat call changes nothing.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `THREE_WS_API_KEY`, `THREE_WS_BASE`, `THREE_WS_TIMEOUT_MS` — keys and tokens: ask the human for the values, never commit them or put them in shared files.
