Personal memory · MCP connector for Claude

Your memory isn't overwritten: it's dated.

You save what you need to remember just by talking to Claude. When something changes, the previous value isn't deleted — it stays on file with the dates it was true. Ask today and you get today's answer; ask about the past and it reconstructs it.

How it works

You talk to Claude. The rest happens on its own.

No new app to open, no forms to fill in. You connect once and your brain is available in any conversation — web, desktop or mobile.

You tell it something

“Remember that my Banco de Chile checking account is 123-456.” Claude works out which domain it belongs to and what date the fact is from.

Or you hand it a document

Attach a PDF, a photo or a spreadsheet in the chat. It reads it — even scanned — sorts it out and files it section by section.

It's filed with a date

Every fact goes in with the date it actually happened, not today's. If it contradicts an earlier one, that one is closed on that date instead of deleted.

You ask whenever you want

In plain language. By default it answers with the current facts; ask for the history and you get the timeline.

What you ask it

Everything that today lives in screenshots and old email.

Save

Remember that the home router is a TP-Link and the password is in 1Password. → add_memory · personal domain
Note that in today's meeting we decided to use Postgres on project X. → add_memory · projects domain
Add this contract (attached) to my second brain. → add_memory × document sections

Look up

Who do I have an NDA with? → search_memory_facts · current only
What tests did I have in 2024 and what did they say? → search_nodes + get_episodes
Give me the history of my bank accounts. → search_memory_facts · only_current = false

Under the hood

Each person, their own graph.

Claude · web · desktop · mobile MCP · OAuth 2.1 + PKCE gateway · authenticates and routes your process another process your graph another graph
Structural isolation

Your information lives in a separate graph, with its own database user and its own process. It doesn't rely on a filter being written correctly.

What the graph stores

The original text of every document, the people and companies that appear in it and how they relate, and the validity of each fact: from when and until when it was true.

Nothing is deleted

A new fact that contradicts an older one closes it with a date. The old one is still there, still queryable, marked as historical.

Connect

Three steps, once.

In Claude, open Settings → Connectors and choose Add custom connector.
Paste this address: https://mybrain.rlz.cl/mcp
Sign in when the window opens. That's it: your brain is available in every conversation.

Don't have an account yet?

Signups are open: no code, no invitation from anyone. Create your account — with email or with Google — and your private graph is prepared there and then. Places on this instance are limited and served first come, first served.

Prefer full control? The project is open source and you can run the whole thing on your own server.

About your data

It stores sensitive things — carefully.

Passwords and tokens: no

Passwords, tokens and card numbers are detected and redacted before anything is written. What gets stored is that the credential exists and where it is, never its value.

Health and finances: yes

Test results, contracts and accounts are stored flagged as sensitive, inside your isolated graph. And the code is public: you can audit exactly what happens.

Frictionless exit

Your whole memory downloads to a single file whenever you want: the text of your documents, who appears in them and every fact with its dates. Without asking anyone's permission.
