The Model Context Protocol, an open standard for connecting AI assistants to other systems. Through it, the assistant uses tools the system offers — in theo's case, querying your apps and working with your MyNotes.

Do I need a paid Claude plan?

No. Claude's Free plan allows one custom connector. In ChatGPT, custom MCP servers require developer mode, which is on paid plans.

Can the assistant see other people's data?

No. It only reaches apps that are yours or your business's, and only each app's tables. The database checks every command before it runs.

In theo, under Settings → Connections. The connection drops immediately.

How much does it cost?

Nothing extra: the MCP server is part of theo, which starts free with no credit card.

How it works

MCP (Model Context Protocol) is the open standard that connects AI assistants to other systems. theo offers tools; Claude picks which ones to use for your request — and shows every one it used.

You

Write
“Summarize this conversation and save it in MyNotes, in the Clients/Acme folder.”
Creates the page in the right place — and the folder, if it doesn't exist yet.

Edit
“In the Acme proposal, change the deadline from 30 to 45 days and add a risks section.”
Changes just that passage and slots in the new section — the rest of the page stays as it was.

Databases
“Create a leads database with name, status (new, talking, closed) and next contact, and add these five.”
A real database that opens as a table, Kanban, list or calendar.
usesnotas_criar_basenotas_base_adicionar
Your apps
“In the Orders app, how much did I sell this week and which orders are late?”
Reads the app's tables and answers with the numbers, changing nothing.
usesapp_estruturaapp_consultar

usesnotas_grafo

For developers

In the terminal too: Claude Code

The spec lives in MyNotes; the code, in the repository. With theo connected, Claude Code reads one side and writes the other.

From spec to code
“Read the Checkout v2 page in MyNotes and implement it.”
A record of what changed
“When you're done, write a summary in MyNotes.”
Data at hand while debugging
“Look up the failed order in the Orders app.”

You stay in control

Claude works on your behalf, with your reach — and nothing more.

The connection only exists after theo's Allow screen, which says who is asking and where access goes.
Only what's yours
Your apps and your business's; in MyNotes, your pages. The database checks every command before it runs.
Reading changes nothing
Queries run read-only. Changes must say which rows — “delete everything” doesn't go through.
You can undo
Deleted pages go to the trash, and Claude can restore them.
Cut it off anytime
In Settings → Connections; access ends immediately. Your password never leaves theo.
