TickTick helps users organize daily work by creating and updating tasks, managing to-do lists, setting due dates and reminders, organizing tasks with tags, and tracking progress across projects and routines.
DeepSeek Harness (DSH) is DeepSeek's agent harness. Each MCP server is one plugin entry in your project config.
This guide connects TickTick MCP to DeepSeek Harness through MewCP, so DeepSeek Harness can use TickTick MCP's 57 tools, like list_projects, get_project_by_id and get_project_with_undone_tasks, without your TickTick MCP credentials ever reaching the app.
TickTick MCP signs in through managed OAuth. MewCP stores the token encrypted, refreshes it before it expires and injects it only at call time. Your agent never holds it, so it can never leak it.
More apps
Work with pages, databases, blocks and collaborative knowledge stored in Notion. Create, update and organize content while building workflows around structured information and documentation.
Create, track, and manage Google Tasks and task lists directly from your AI workflows. This stateless, multi-tenant MCP server exposes the Google Tasks API for listing, creating, updating, completing, and deleting both tasks and task lists. Mutating tools such as update_task and update_tasklist return both the before and after state of the resource, making it easy to build assistants and automations that manage to-do lists and reminders on a users behalf
Connect AI agents to Miro to create, read, update, and organize collaborative boards, diagrams, sticky notes, shapes, and other visual workspace content.
Connect AI agents to ClickUp to manage tasks, projects, documents, lists, comments, and workflows, while searching workspace data and automating project management activities.
Other clients
TickTick MCP works the same way in every client below. Pick yours for its own guide.
Free to start.
Scope access to the exact TickTick MCP tools and accounts you allow, work and personal side by side. Anything outside that scope is refused at call time, even when the model asks for it.
Each call is logged: what ran, on which account, and whether it worked. Failures come back structured, so the agent knows whether to retry instead of guessing.
Every app sits behind one secure MCP URL, and there is no server for you to deploy or keep running. Add an integration in the dashboard and it is live on the next call, with no config to change and no new credentials to wire up. Tools load only when a task needs them, so your agent stays fast and focused however many apps you connect.
