Does TickTick have an MCP server, and can an agent connect to it?
Yes. TickTick has an official MCP server. The server lists 55 tools, signs an agent in with OAuth and speaks the 28 Jul 2026 MCP spec.

In the drive of 6 Oct 2026, our agent got its TickTick API key in a browser, without a person. Personal API key made in Settings > Account > API Keys (docs say 'API Token'); OAuth is authorization_code only with browser consent, DCR registration, no device flow

Can an AI agent pay for TickTick?
Reaches the checkout: stopped at the card form.
- Stripe Checkout
It has a free plan.
What would let agents pay on their own
- Accept x402 or MPP on your API. Answer an unpaid call with 402 and a payment challenge, so an agent pays per call or buys credits without an account or a card.Step-by-step guide
- List your plans on Stripe Projects. Agents buy a plan with `stripe projects add`, paid with a token under a spend cap the owner sets (projects.dev).Step-by-step guide
No x402/MPP/UCP/402; no billing API; Premium US$4.99/month via Stripe Checkout with card fields (not paid)

How an agent connects · 5 tips
/api/tools/ticktick.json/tools/ticktick.mdMCP get_tool {"slug":"ticktick"}
- Make a personal API key once in the web settings, then use MCP at https://mcp.ticktick.com (2026-07-28, Bearer key) or REST at api.ticktick.com/open/v1
- MCP argument names differ from REST (e.g. checklist_item_id); errors are clear pydantic messages
- Tagging a task does not create a tag object; POST /open/v1/tag if it must be listed
- Validation errors come as HTTP 500; read errorMessage
- Free plan silently drops task duration
