Obsidian Tasks MCP Server

A Model Context Protocol (MCP) server for extracting and querying Obsidian Tasks from markdown files. Designed to work with Claude via the MCP protocol to enable AI-assisted task management.

Features

Extract tasks from Obsidian markdown files with a format compatible with the Obsidian Tasks plugin
Identify completed and pending tasks
Access task metadata including:
- Status (complete/incomplete)
- Due dates
- Scheduled dates
- Start dates
- Created dates
- Tags
- Priority
- Recurrence rules

Tools

This MCP server provides the following tools:

list_all_tasks

Extracts all tasks from markdown files in a directory, recursively scanning through subfolders.

Input Parameters:

path (string, optional): The directory to scan for markdown files. If not specified, defaults to the first allowed directory.

Returns: A JSON array of task objects, each containing:

{
  "id": "string",          // Unique identifier (filepath:linenumber)
  "description": "string", // Full text description of the task
  "status": "complete" | "incomplete", // Task completion status
  "filePath": "string",    // Path to the file containing the task
  "lineNumber": "number",  // Line number in the file
  "tags": ["string"],      // Array of tags found in the task
  "dueDate": "string",     // Optional - YYYY-MM-DD format 
  "scheduledDate": "string", // Optional - YYYY-MM-DD format
  "startDate": "string",   // Optional - YYYY-MM-DD format
  "createdDate": "string", // Optional - YYYY-MM-DD format
  "priority": "string",    // Optional - "high", "medium", or "low"
  "recurrence": "string"   // Optional - recurrence rule
}

query_tasks

Searches for tasks based on Obsidian Tasks query syntax. Applies multiple filters to find matching tasks.

Input Parameters:

path (string, optional): The directory to scan for markdown files. If not specified, defaults to the first allowed directory.
query (string, required): The query string using Obsidian Tasks query syntax. Each line is treated as a filter.

Returns: A JSON array of task objects that match the query, with the same structure as list_all_tasks.

Supported Query Syntax:

Status filters:
- done - Show completed tasks
- not done - Show incomplete tasks
Date filters (due):
- Note on semantics: due today is an exact match (only tasks due exactly today). Use range operators to include earlier/later dates.
- due today - Tasks due today
- due before today - Tasks due before today (exclusive)
- due after today - Tasks due after today (exclusive)
- due on or before today - Tasks due today or earlier (inclusive)
- due on or after today - Tasks due today or later (inclusive)
- due on YYYY-MM-DD or due YYYY-MM-DD - Tasks due on a specific date
- due before YYYY-MM-DD - Tasks due before a date (exclusive)
- due after YYYY-MM-DD - Tasks due after a date (exclusive)
- due on or before YYYY-MM-DD - Tasks due on/before a date (inclusive)
- due on or after YYYY-MM-DD - Tasks due on/after a date (inclusive)
- no due date - Tasks with no due date
- has due date - Tasks with a due date
Start date filters:
- Note on semantics: starts today is an exact match (only tasks that start today). Use range operators to include earlier/later dates.
- starts today - Tasks starting today
- starts on YYYY-MM-DD or starts YYYY-MM-DD - Start on a specific date
- starts before YYYY-MM-DD - Start before a date (exclusive)
- starts after YYYY-MM-DD - Start after a date (exclusive)
- starts on or before YYYY-MM-DD - Start on/before a date (inclusive)
- starts on or after YYYY-MM-DD - Start on/after a date (inclusive)
- no start date - Tasks with no start date
- has start date - Tasks with a start date
Tag filters:
- no tags - Tasks with no tags
- has tags - Tasks with at least one tag
- tag includes #tag - Tasks with tags containing "tag"
- tag does not include #tag - Tasks without tags containing "tag"
Path filters:
- path includes string - Tasks in files with paths containing "string"
- path does not include string - Tasks in files with paths not containing "string"
Description filters:
- description includes string - Tasks with descriptions containing "string"
- description does not include string - Tasks with descriptions not containing "string"
Priority filters:
- priority is highest - Tasks with highest priority
- priority is high - Tasks with high priority
- priority is medium - Tasks with medium priority
- priority is low - Tasks with low priority
- priority is lowest - Tasks with lowest priority
- priority is none - Tasks with no priority

Example Query:

not done
due before 2025-05-01
tag include #work

This would return all incomplete tasks due before May 1, 2025, that have the #work tag.

Inclusive OR example (single line):

due on or before today OR starts on or before today
