# Ticker

> Ticker is a focus-friendly habit tracker and todo manager with first-class Model Context Protocol (MCP) support. AI assistants — Claude, ChatGPT, Cursor — can read, reason over, and create the user's tasks directly. Daily streaks use forgiving grace periods (a missed day or two doesn't break the streak), todo capture is two seconds, and visual cues replace nagging notifications. Built for neurodivergent minds and anyone who finds rigid productivity systems exhausting. Part of the Tazzen ecosystem.

Monday triage in 5 minutes instead of 30: the user's AI rebuilds their state — what is overdue, blocked, slipping — without the user having to explain it. AI assistants and integrations act on the user's behalf via two transports: a REST API and a Model Context Protocol (MCP) server. Pick whichever fits your client.

All write actions require a Personal Access Token issued by Tazzen Identity. There is no anonymous mutation. The user picks scopes (`habits:read`, `habits:write`, `todos:read`, `todos:write`, `categories:read`, `categories:write`) when they create a token and can revoke it in one click. Each token's API and MCP activity is logged so the user can audit what every connected agent did.
