Overview

AI-generated overview

Cobrain gives an assistant shared Markdown memory across Claude, ChatGPT, Claude Code and Codex via a remote endpoint.

What it does
Cobrain is a remote MCP server that provides shared Markdown memory for several AI assistants, including Claude, ChatGPT, Claude Code and Codex. The registry description says it uses OAuth rather than API keys. No tool list is published, so the exact operations are not documented here.
When to use it
Consider it when you want the same Markdown-based memory available to more than one assistant or coding agent, and you prefer signing in with OAuth instead of managing API keys.
Requirements
A remote MCP connection to the provider's endpoint over streamable HTTP. Authentication is by OAuth; no API keys, environment variables or headers are declared. Network access is required.
Before you install
The server stores shared Markdown memory, so anything you save may be visible to every assistant account connected to it. No tool list is published, so what it can read, write or delete is not documented. Review what you store before connecting multiple assistants.
