Optimike Obsidian Tasks MCP

A Model Context Protocol (MCP) server for extracting and querying Obsidian Tasks from markdown files. Designed to work with MCP clients (Claude, Codex, IDEs, etc.) to enable AI‑assisted task management.

French version: README.fr.md

Prerequisites

• Node.js >= 16
• Obsidian Desktop
• Obsidian Tasks plugin configured in your vault: https://github.com/obsidian-tasks-group/obsidian-tasks
• Tasks config file present at: <vault>/.obsidian/plugins/obsidian-tasks/data.json

Quickstart

npx optimike-obsidian-tasks-mcp /path/to/obsidian/vault

Features

• Extract tasks from Obsidian markdown files with compatibility for Obsidian Tasks settings
• Status mapping driven by your Tasks plugin config (core + custom statuses)
• Supports Tasks global filter + presets (optional)
• Date filters with relative ranges (EN/FR) and comparisons
• Optional Dataview task format parsing ([due:: 2024-01-01], etc.)
• Optional file metadata + frontmatter meta dates (with fallback to filesystem)
• Output as JSON or Markdown

Tasks plugin config (source of truth)

This server relies on the Obsidian Tasks plugin: https://github.com/obsidian-tasks-group/obsidian-tasks

This server reads your Tasks plugin settings (statuses, presets, global filter) from:

<vault>/.obsidian/plugins/obsidian-tasks/data.json

Make sure that file reflects your current Tasks configuration.

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): Directory to scan. Defaults to the vault root.
• includePaths (string[], optional): Only include paths containing any of these substrings.
• excludePaths (string[], optional): Exclude paths containing any of these substrings.
• includeNonTasks (boolean, optional): Include NON_TASK statuses.
• includeFileMetadata (boolean, optional): Include file created/modified dates.
• includeMetaDates (boolean, optional): Include frontmatter meta dates (e.g., création/modification).
• metaFallbackToFile (boolean, optional, default true): If meta dates are missing, fall back to file dates.
• applyGlobalFilter (boolean, optional): Apply Tasks globalFilter.
• responseFormat ("json" | "markdown", optional): Output format.
• responseLimit (number, optional): Limit number of tasks returned.
• useCache (boolean, optional, default true): Cache per-file parsing.

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" | "cancelled" | "in_progress" | "non_task",
  "statusName": "string", // Optional - status name from Tasks config
  "statusType": "string", // Optional - TODO | DONE | IN_PROGRESS | CANCELLED | NON_TASK
  "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
  "doneDate": "string",    // Optional - YYYY-MM-DD format
  "cancelledDate": "string", // Optional - YYYY-MM-DD format
  "metaCreatedDate": "string", // Optional - from frontmatter
  "metaModifiedDate": "string", // Optional - from frontmatter
  "fileCreatedDate": "string", // Optional - filesystem
  "fileModifiedDate": "string", // Optional - filesystem
  "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): Directory to scan. Defaults to the vault root.
• query (string, required): Tasks query. Each line is treated as a filter.
• queryFilePath (string, optional): Used to resolve {{query.file.*}} placeholders.
• All other parameters from list_all_tasks (include/exclude, meta dates, global filter, etc.)

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

Supported Query Syntax (subset + extras):

• Status filters:
• done / not done (aligned with Tasks semantics)
• status.type is TODO|DONE|IN_PROGRESS|CANCELLED|NON_TASK
• status.name is "In Progress"

• Date filters:
• due|scheduled|start|created on|before|after YYYY-MM-DD
• due|scheduled|start|created on or before|on or after <date>
• Relative EN/FR: today, tomorrow, yesterday, this week, next week, last week, aujourd'hui, demain, hier, cette semaine, semaine prochaine
• Ranges: due in next 7 days
• Meta/file: meta created before 2026-01-01, file modified after 2025-12-31

• Tag filters:
• no tags, has tags
• tag include #tag / tag do not include #tag

• Path filters:
• path includes string, path does not include string
• folder includes string, filename includes 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 high - Tasks with high priority
• priority is medium - Tasks with medium priority
• priority is low - Tasks with low 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.

Usage

Installation

From npm (recommended):

# Install globally
npm install -g optimike-obsidian-tasks-mcp

# Or use directly with npx without installing
npx optimike-obsidian-tasks-mcp /path/to/obsidian/vault

From source:

git clone https://github.com/optimikelabs/optimike-obsidian-tasks-mcp.git
cd optimike-obsidian-tasks-mcp
npm install
npm run build

Running the Server

Using npm package (recommended):

# If installed globally
optimike-obsidian-tasks-mcp /path/to/obsidian/vault

# Or with npx (no installation required)
npx optimike-obsidian-tasks-mcp /path/to/obsidian/vault

From source:

node dist/index.js /path/to/obsidian/vault

You can specify multiple directories:

npx optimike-obsidian-tasks-mcp /path/to/obsidian/vault /another/directory

HTTP transport (optional)

The server also supports Streamable HTTP transport.

MCP_TRANSPORT_TYPE=http MCP_HTTP_HOST=127.0.0.1 MCP_HTTP_PORT=3011 \
  npx optimike-obsidian-tasks-mcp /path/to/obsidian/vault

Session mode (default stateful):

• MCP_HTTP_SESSION_MODE=stateful (auto sessionId)
• MCP_HTTP_SESSION_MODE=stateless (no session)

Performance & scope

To avoid scanning too much, use includePaths/excludePaths in MCP calls, or set defaults via env vars:

• MCP_TASKS_INCLUDE_PATHS (CSV): vault-relative paths, e.g. Efforts/Projets,Calendrier/NOTES PÉRIODIQUES
• MCP_TASKS_EXCLUDE_PATHS (CSV)
• MCP_TASKS_MAX_FILES (number)
• MCP_TASKS_CONCURRENCY (number, default 8)

Testing

To run the test suite:

npm test

See TESTING.md for detailed information about the test suite.

Inspection (MCP Inspector)

npm run inspect:stdio
# or
npm run inspect:http

Using with MCP clients (Claude, Codex, etc.)

    "optimike-obsidian-tasks": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
