Ticktick for AI agents

TickTick is a task manager and to-do list app across devices, used by individuals and small teams to organize projects, deadlines, and daily tasks in one list. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

await arc0.policies.set('ticktick', {
  read: 'allow',

04 · AUTH AND DATA

How Ticktick connects.

Users sign in to Ticktick on Arc0 Connect and approve the scopes you request. Build with Arc0’s Ticktick OAuth app, or bring your own so the Ticktick consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

The same Ticktick connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Ticktick and Arc0, answered.

Q01

Can I use Ticktick with Claude, ChatGPT or Cursor?

Yes. Connect Ticktick to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Ticktick actions you allow.

Q02

How do users connect Ticktick?

Users sign in to Ticktick on Arc0 Connect and approve the scopes you request. Build with Arc0’s Ticktick OAuth app, or bring your own so the Ticktick consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

Q03

Which Ticktick actions can my agent take?

14 in total: 5 read, 7 write and 2 destructive, such as “create Task”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Ticktick?

Yes. Actions like “delete Task” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call Ticktick too?

Yes. The same Ticktick connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
