A powerful, locally-hosted task management application with Obsidian integration and a Model Context Protocol (MCP) server.
DeltaTask MCP server is a hosted integration for AI assistants that speak the Model Context Protocol. A powerful, locally-hosted task management application with Obsidian integration and a Model Context Protocol (MCP) server.
Once DeltaTask is connected, these are the calls the assistant has available:
get_task_by_id — Get a specific task by IDsearch_tasks — Find tasks by title, description, or tagscreate_task — Create a new taskupdate_task — Update a task's propertiesdelete_task — Remove a tasksync_tasks — Sync tasks from Obsidian markdown into SQLitelist_tasks — List all tasksget_statistics — Retrieve metrics about taskscreate_subtasks — Split a task into multiple subtasksget_all_tags — Get all unique tag namesget_subtasks — Get subtasks for a given parent taskfinish_task — Mark a task as completedBeing a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
Among the planning and project tracking options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. DeltaTask's toolset — get_task_by_id, search_tasks, create_task and 11 more — is a fair guide to whether it matches your workflow. It is maintained by brysontang; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
