Your DoBox, in any AI tool you use.
this+that ships an MCP server so your DoBox is reachable from Claude Code, Claude Desktop, ChatGPT, Cursor, and anywhere else the Model Context Protocol works. Ask "what's overdue?" or "summarize my DoBox for the day" without leaving your editor or chat window.
An open standard for AI-to-tool connections
The Model Context Protocol is an open standard from Anthropic that lets AI assistants connect to external tools and data through a common interface. We use MCP to bring third-party tools into our workflow builder; the DoBox MCP server is the inverse. Your DoBox tasks become available in any MCP-compatible AI client. One protocol, both directions. Learn more at modelcontextprotocol.io.
One command and you're connected
The fastest path is a single terminal command. It registers the MCP server with Claude Code:
claude mcp add --transport http this_and_that https://mcp.thisandthat.chat/mcp The add command only writes config; it doesn't trigger sign-in. Run /mcp in Claude Code and select the server to authorize, or just ask a DoBox question and the browser sign-in will open automatically. Prefer the plugin install path? Run /plugin marketplace add thisnthat-lab/mcp-server, then /plugin install dobox-cowork@thisnthat.
Natural language everywhere, plus a /dobox shortcut in ChatGPT
Once connected, ask in plain English: "what's overdue?", "summarize my DoBox for today", "show me 10 resolved DoBox items". Your assistant picks the right tool and arguments automatically. ChatGPT is the only client that auto-creates a /dobox shortcut. Claude Code, Claude Desktop, and Claude on the web all use natural language only, since Claude doesn't expose MCP tools as slash commands.
One URL, standard OAuth
The DoBox MCP server is a standard HTTP MCP endpoint. Any compliant client can connect directly. No plugin required. Server URL: https://mcp.thisandthat.chat/mcp.
Claude Desktop
Open Customize → Connectors, click the + button, then Add custom connector. Enter "this+that" as the name and https://mcp.thisandthat.chat/mcp as the URL, then click Add. Once the connector loads, click Connect, and your browser will open for sign-in.
ChatGPT
ChatGPT supports custom MCP connectors across plans, including Free, on the web (not mobile). Enable Developer Mode under Settings → Apps → Advanced settings, then go to Settings → Connectors → Create custom connector. Enter "this+that" as the name and https://mcp.thisandthat.chat/mcp as the server URL; leave the rest blank. ChatGPT auto-creates a /dobox shortcut after the connector is added. Type /dobox directly, or just ask in plain English.
Cursor, custom integrations, and other clients
Point your client at the server URL above as an HTTP MCP endpoint. Authentication is OAuth 2.0 with Dynamic Client Registration, so your client registers itself the first time it connects, then signs in via your normal this+that browser session. Most clients discover the OAuth metadata endpoints automatically.
One tool now, more on the roadmap
The current release exposes a single read tool. Write and resolve tools are on the roadmap.
dobox_get_entries
Fetch your DoBox entries. Filter by UNRESOLVED (default) or RESOLVED, with a configurable limit. Returns subject, description, due date, a count of attached communications, and any AI-suggested status.
Coming soon
Create new entries from natural language, mark entries resolved, and update due dates and descriptions, all from inside your AI client.
Read-only, OAuth-authenticated, scoped to you
The connector reads entries from your DoBox only: subject, description, due date, a count of attached communications, and AI-suggested status. It cannot read other users' data, and it does not currently write or delete anything. Authentication uses standard OAuth 2.0; tokens are stored by your AI client (in your OS keychain on macOS, for example), and we never see them.
