Things MCP Server
This Model Context Protocol (MCP) server lets you use ChatGPT, Codex, Claude Desktop, and other MCP clients to interact with your task management data in Things 3 from Cultured Code. You can ask your assistant to create tasks, analyze projects, help manage priorities, and more.
This server leverages the Things.py library and the Things URL Scheme.
Support the Project
If you find this project helpful, consider supporting its development:
Features
- Access to all major Things lists (Inbox, Today, Upcoming, etc.)
- Project and area management
- Tag operations
- Advanced search capabilities
- Recent items
- Detailed item information including checklists
- Support for nested data (projects within areas, todos within projects)
- Someday project filtering: tasks in Someday projects are automatically excluded from Today, Upcoming, and Anytime views, matching Things UI behavior
Installation
Prerequisites
- macOS (Things 3 is Mac-only)
- Things 3 app with "Enable Things URLs" turned on (Settings → General)
- An MCP client, such as the ChatGPT desktop app, Codex, Claude Desktop, or Claude Code
- uv Python package manager:
brew install uv
Install via uvx (Any MCP Client)
Things MCP is published on PyPI and can be run directly with uvx:
uvx things-mcp
Configure your MCP client to use uvx with things-mcp as the argument.
Claude Desktop
Option 1: One-Click Install (Recommended)
- Download the latest file from the releases page
- Double-click the
.mcpbfile - Done!
Option 2: Manual Config
- Go to Claude → Settings → Developer → Edit Config
- Add the Things server:
{
"mcpServers": {
"things": {
"command": "uvx",
"args": ["things-mcp"]
}
}
}
- Save and restart Claude Desktop
Claude Code
claude mcp add-json things '{"command":"uvx","args":["things-mcp"]}'
To make it available globally (across all projects), add -s user:
claude mcp add-json -s user things '{"command":"uvx","args":["things-mcp"]}'
ChatGPT Desktop and Codex
The ChatGPT desktop app, Codex CLI, and Codex IDE extension share the same local MCP configuration. The quickest way to add Things MCP is with the Codex CLI:
codex mcp add things -- uvx things-mcp
Confirm that the server is configured:
codex mcp list
You can also configure it in the ChatGPT desktop app:
- Open Settings → MCP servers
- Select Add server
- Enter
thingsas the name, choose STDIO, and enter the result ofwhich uvxas the command to launch (should look similar to /opt/homebrew/bin/uvx) - Enter
things-mcpunder arguments - Save the server and select Restart
[!IMPORTANT] When using the ChatGPT desktop client, you must use Work mode to access Things MCP. Select ChatGPT from the top-left menu, then choose Work from the toggle at the top of the page. Regular Chat mode does not use locally configured MCP tools. You can also select the separate Codex view, which shares the same MCP configuration.
In ChatGPT Work or Codex, type /mcp to check that the Things server is connected, then try asking, "What's in my Things inbox?"
This local setup does not work in ChatGPT on the web because the web client does not read local Codex MCP configuration. See OpenAI's MCP documentation and ChatGPT Work and Codex for current availability and interface details.
Verify it's working
After installation:
- If using Claude Desktop, you should see "Things MCP" in the "Search and tools" list
- If using ChatGPT Work or Codex, type
/mcpand confirm that the Things server is connected - Try asking: "What's in my Things inbox?"
Sample Usage with Claude Desktop
- "What's on my todo list today?"
- "Create a todo to pack for my beach vacation next week, include a packing checklist."
- "Evaluate my current todos using the Eisenhower matrix."
- "Help me conduct a GTD-style weekly review using Things."
- "Show me tasks that haven't been modified in over a month."
Tips
- Create a project in Claude with custom instructions that explains how you use Things and organize areas, projects, tags, etc. Tell Claude what information you want included when it creates a new task (eg asking it to include relevant details in the task description might be helpful).
- Try adding another MCP server that gives Claude access to your calendar. This will let you ask Claude to block time on your calendar for specific tasks, create todos from upcoming calendar events (eg prep for a meeting), etc.
- Use task ages to identify stale items: "Which tasks in my Anytime list are older than 2 weeks?"

Tool Parameters
Pagination (most read tools)
The list/search read tools (get-inbox, get-today, get-upcoming, get-anytime, get-someday, get-logbook, get-trash, get-todos, get-projects, get-areas, get-tags, get-tagged-items, get-headings, search-todos, search-advanced, get-recent) accept optional pagination:
limit- Maximum number of items to return (default: all;get-logbookdefaults to 50)offset- Number of items to skip from the start (default: 0)
When neither is set, output is unchanged. When set, a Showing X-Y of Z items header is prepended so you know how much more there is. An offset past the end is reported distinctly from an empty result.
These same read tools also return structured content alongside the human-readable text: MCP clients receive the raw item dicts plus count/total/offset/limit under structured_content, so data can be consumed programmatically without parsing the formatted text.
get-todos
project_uuid(optional) - Filter todos by projectinclude_items(optional, default: true) - Include checklist items
get-projects / get-areas / get-tags
include_items(optional, default: false) - Include contained items
search-advanced
status- Filter by status (incomplete/completed/canceled)start_date- Filter by start date (YYYY-MM-DD)deadline- Filter by deadline (YYYY-MM-DD)tag- Filter by tagarea- Filter by area UUIDstop_date- Filter by completion/cancellation date (YYYY-MM-DD, optionally with an operator such as '>=2024-01-01', or 'past'/'future')project- Filter by project UUID (includes items under the project's headings)type- Filter by item type (to-do/project/heading)last- Filter by creation date (e.g., '3d' for last 3 days, '1w' for last week)
get-recent
period(required) - Rolling window back from now (e.g., '1d' = the last 24 hours, '1w', '2m', '1y'); months ≈ 30 days, years ≈ 365 days. Returns open (incomplete) items only, newest first
get-logbook
period(optional, default: '7d') - Look-back window by completion date. Acceptsd/w/m/y(e.g., '3d', '1w', '2m', '1y'); months ≈ 30 days, years ≈ 365 dayslimit(optional, default: 50) - Maximum number of items to returnproject_uuid(optional) - Only return items from this project, including items under its headings
Returns both completed and canceled items; each item's status tells them apart.
get-tag-usage

bulk-update-todos
Applies the same change to every todo in ids in a single operation. Requires the Things auth token to be enabled (Things → Settings → General → Enable Things URLs → Manage); the server reads it automatically.
ids(required) - List of todo UUIDs to updatelist/list_id- Move all into a project/area (by title or UUID)tags/add_tags- Replace or append tags on allwhen- Reschedule all (keyword or YYYY-MM-DD)deadline- Set deadline on all (YYYY-MM-DD)heading/heading_id- Move all under a heading (by title or UUID)completed/canceled- Mark all completed or canceled

Troubleshooting
If it's not working:
-
Make sure Things 3 is installed and has been opened at least once
- The Things database needs to exist for the server to work
-
Check that "Enable Things URLs" is turned on
- Open Things → Settings → General → Enable Things URLs
-
Claude Desktop can't find
uvx- Install uv globally with Homebrew (
brew install uv) - Alternative: Use the full path to

HTTP Transport
By default, the server uses stdio transport for communication with MCP clients. For remote access scenarios, you can run the server with HTTP transport.
Configuration
Set these environment variables to enable HTTP transport:
| Variable | Default | Description |
|---|---|---|
THINGS_MCP_TRANSPORT |
stdio |
Transport type: stdio or http |
THINGS_MCP_HOST |
127.0.0.1 |
HTTP server bind address |
THINGS_MCP_PORT |
8000 |
HTTP server port |
Example
# Using uvx
THINGS_MCP_TRANSPORT=http THINGS_MCP_HOST=0.0.0.0 THINGS_MCP_PORT=8000 uvx things-mcp
# Or from source
THINGS_MCP_TRANSPORT=http THINGS_MCP_HOST=0.0.0.0 THINGS_MCP_PORT=8000 uv run things-mcp
See .env.example for a sample configuration file.
