Connect Claude to your notes
Give Claude a place for your own notes and documents. Ask a question and Claude answers with what you wrote.
Works with MCP Hosted and MCP Self-hosted
What Claude can do with Brain
Search your notes
Claude searches your notes and documents and quotes what it found.
Keep them up to date
Ask Claude to add a note, sort a list or tidy up a page.
Read-only or with changes, per seat
You decide per seat whether Claude may also make changes.
Set up in three steps
From sign-up to your first question.
Pick MCP Hosted or MCP Self-hosted
With MCP Hosted we run the server for you. With MCP Self-hosted you run it on your own server. Add the Brain add-on to either one.
Switch it on
Brain needs no login details from another service. Add it to your seat and you are done.
Ask Claude
Connect Claude with your personal link and ask your first question.
Hosted for you, or on your own server
With MCP Hosted we run the server for you, hosted in Germany. With MCP Self-hosted it runs in Docker on your own server and your login details stay there.

How do you connect Claude to your notes?
Give Claude a place for your notes and documents, and ask questions about what you wrote. You add the Brain add-on to MCP Hosted or MCP Self-hosted. Claude then gets a notes folder it can search, read and write.
Claude and other MCP-compatible assistants then reach your notes through MCP, the open standard that lets an AI assistant use other software. Your notes are plain text files (markdown), so you can also open and edit them in any editor.
Why connect Claude to your notes?
A new chat starts empty, so you explain the project and the decisions again each time. With Brain that context lives in notes. Claude reads them at the start of a task and updates them at the end. Common uses:
- project notes and decisions Claude reads before it starts;
- meeting notes Claude turns into a clear summary;
- a log per client or project, added to after each session;
- reference material your team writes once.
What can Claude do in your notes?
Claude can search the folder, read and write notes, add to a note, and move or delete notes. You ask in your own words, for example:
Is it safe to let Claude write?
Brain is the one tool that can make changes from the start, because a notes folder Claude cannot save to is of little use. With version history on, every change is kept, so you can always see what changed and go back. For a colleague who only needs to search, turn off Can make changes on their seat.
What do you need?
- A seat on MCP Hosted, or MCP Self-hosted, with the Brain add-on.
- On MCP Self-hosted: a folder on your server for the notes.
The Brain setup guide explains each setting, including version history.
How is Brain different from a free skill?
A free Claude skill describes how to do one task. Brain holds the context for it. They work well together.
What does it cost?
On MCP Self-hosted the Brain add-on costs € 72,60 excl. VAT: € 60,00 per year. On MCP Hosted you add it to your seat for a monthly amount. The pricing page shows both.
Start small: one notes folder, with version history on from day one.
Frequently asked questions
No. Skills are separate, free downloads — no license or entitlement required.
Yes, per tool and per seat. You choose read-only or Can make changes for each tool when you add a seat in My Account → MCP Self-hosted. Every tool defaults to read-only except Brain, which can make changes from the start. See entitlements vs tool modes.
Yes. Copy the whole install folder, including ./state, and the activation moves with it, because the instance id lives in that folder. On a fresh install, release the old activation on the Activations tab first, then refresh the license on the new server. Activations without a check for 30 days are released automatically. See MCP license management.
Not once delivery has started. EU consumers normally have 14 days to withdraw. Licenses for MCP Self-hosted, add-ons and extra seats are delivered as soon as the order is paid, and at checkout you agree to that and confirm that the right of withdrawal ends with it. The right of withdrawal form lists any order that still qualifies. Business orders cannot be withdrawn through the form.
Just MCP Self-hosted plus whichever add-ons you actually need. Tools you haven’t licensed simply aren’t loaded or exposed to your AI client.
Add a Seat from My Account → MCP Self-hosted. Each Seat gets its own token and can be scoped to only the tools that teammate needs.
MCP Self-hosted costs € 217,80 excl. VAT: € 180,00 per year. Add-ons start from € 72,60 excl. VAT: € 60,00 per year and differ in price. Each line on a license, MCP Self-hosted, every add-on and every extra seat, is its own yearly recurring payment through Mollie with its own renewal date. Some products can be billed monthly, with a 12-month minimum term. The pricing calculator adds up a setup for you.
VAT is calculated at checkout from your billing details. A business in the EU with a valid VAT number gets reverse charge, so enter that number at checkout. For a question about the VAT on an existing order, use the contact form and include the order number.
MCP Self-hosted includes 3 seats and 1 activation. One server can serve three people or devices, each with their own token. A fourth identity needs an extra seat at € 18,15 excl. VAT: € 15,00 per year. A second container on the same license is refused until you release the first activation. MCP seats explains tokens, labels and limits.
MCP Self-hosted sends a small diagnostics payload with every license check, so we can see which version runs and whether checks succeed. It contains no data from your tools, inbox, store or database. MCP diagnostics lists exactly what is sent and what you see in My Account.
Nothing breaks immediately. Your server keeps running on its last successful entitlements for a 96-hour grace period before anything is restricted.
A failed charge puts the line on Payment issue and everything keeps working. If it is still unpaid after 7 days, the line is suspended. For the MCP Self-hosted line that blocks every tool call. A cancelled line runs until the end of the period you paid for and then stops. A suspended license gets no 96-hour grace period; that only covers a server that cannot reach AddoCore. Details are in MCP license renewal.
An activation is one running MCP Self-hosted server. A seat is one person or device that connects to it, with its own token, its own tools and its own setting per tool: read-only or Can make changes. One license can have several seats against a single activation. See MCP seats.
Entirely on your own infrastructure — a Docker container you host yourself. Nothing about a tool call routes through a third-party cloud.
