Use this+that from Claude and ChatGPT
this+that runs a public MCP server, so an AI assistant you already use can reach your DoBox and your Brain. Ask Claude what’s overdue, have it close out a task, or have it write up a page in your Brain, all without opening this+that.
Connect it
In Claude Code, one command does it:
claude mcp add --transport http this_and_that https://mcp.thisandthat.chat/mcp
Then run /mcp and pick the server to sign in.
For Claude Desktop, open Settings, then Developer, then Edit Config, and add the server under
mcpServers. Restart Claude Desktop, and it asks you to sign in the first time you use it.
In ChatGPT, switch on Developer Mode under Settings, Apps, Advanced settings. Then go to Settings,
Connectors, Create custom connector, enter https://mcp.thisandthat.chat/mcp, and leave every other
field blank. ChatGPT adds a /dobox shortcut once the connector is in place.
Other MCP clients work the same way. Point the client at the server URL and let it discover the OAuth metadata.
What it can reach
Your DoBox tasks and the messages attached to them, your Brain spaces and pages, and your task groups and labels. It both reads and writes, so an assistant can create a task, resolve one, comment on it, or add a page to your Brain. It sees what your own account can already see.
Sign-in uses OAuth. Your AI client holds its own access token, usually in your operating system keychain, and this+that never sees that token.
Removing it
In Claude Code, run claude mcp remove this_and_that. In Claude Desktop, delete the entry from your
config and restart. In ChatGPT, delete the connector under Settings, Connectors. Signing out of
this+that and back in invalidates the OAuth session at the source.
