Which app do you use?
Pick your app above. We remember it, so next time the button says “Install in …”.
This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.
Run this in your terminal
claude mcp add --transport http mybrain-ai https://mcp.mybrain.ai/mcp/ --header 'Authorization: your-value'Fill in the empty values before running it.
Or copy the settings yourself
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json
{
"mcpServers": {
"mybrain-ai": {
"url": "https://mcp.mybrain.ai/mcp/",
"headers": {
"Authorization": "your-value"
}
}
}
}Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Common questions
Is myBrain safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
You need to fill in: Authorization
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 23 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Context7, Codebase Memory, Exa

myBrain MCP
myBrain is your personal knowledge base: everything you upload, link, record or write becomes a knowledge graph you can search, explore and reason over. This repository is the public home of the MCP server entry and of the files that teach an AI agent how to use your brain well.
| Endpoint | Transport | Auth |
|---|---|---|
https://mcp.mybrain.ai/mcp/ | Streamable HTTP | OAuth 2.1 sign-in, or Authorization: Bearer |
Keep the trailing slash in the URL.
Clients that support OAuth (claude.ai, ChatGPT, Claude Code) need only the URL: they open the myBrain sign-in, you choose what to grant on the consent page, and the client receives its own token. Every other client uses an MCP API key, created in myBrain: Settings → Connected Apps → MCP Integrations.
Both carry scopes: mcp:read (search and read tools), mcp:write (add sources, approve, import memories), mcp:orchestrator (ask_mybrain). Signed-in apps and API keys are listed in the same Settings page, and revoking one there cuts its access immediately.
Connect
claude.ai (also used by the Claude desktop and mobile apps): Settings → Connectors → Add custom connector, paste https://mcp.mybrain.ai/mcp/ and sign in to myBrain.
ChatGPT (plans with Developer mode): Settings → Apps & Connectors → Advanced settings → turn on Developer mode, then Create a connector with the URL https://mcp.mybrain.ai/mcp/ and authentication OAuth, and sign in to myBrain.
Claude Code, signing in:
claude mcp add --transport http mybrain https://mcp.mybrain.ai/mcp/claude mcp login mybrain # or /mcp inside a session
or with an API key:
claude mcp add --transport http mybrain https://mcp.mybrain.ai/mcp/ --header "Authorization: Bearer YOUR_MCP_API_KEY"Claude Desktop (config file), Cursor, VS Code (mcpServers in the client config):
{"mcpServers": { "mybrain": { "url": "https://mcp.mybrain.ai/mcp/", "headers": { "Authorization": "Bearer YOUR_MCP_API_KEY" } } } }
Teach your agent to use it
Connecting the server is not enough. The agent also has to know *when* to search your brain instead of asking you, which tool is the cheap one, and that every write becomes a source pending your approval. Pick what fits your client:
| File | Use |
|---|---|
skill/mybrain/SKILL.md | Claude Code skill. Copy the skill/mybrain/ folder into ~/.claude/skills/ (personal) or /.claude/skills/ (project). |
templates/CLAUDE.md | Block to paste into a project or global CLAUDE.md. |
templates/AGENTS.md | Same guidance for clients that read AGENTS.md (Codex, Cursor, others). |
All three assume the server is connected as mybrain (tool names mcp__mybrain__* in Claude Code).
Tools
Read (mcp:read): recall_memories, list_memories, search_user_knowledge, search_passages, read_source_passages, search_knowledge, search_sources, list_sources, explore_node, trace_path, get_knowledge_overview, list_knowledge_fields, get_knowledge_node, get_related_concepts, list_chat_threads, get_chat_history, get_suggested_questions, get_ingestion_status, get_usage_summary.
Write (mcp:write): add_source_text, add_source_url, add_source_youtube, approve_source, import_memories. Writes land as a source pending your approval in myBrain and are processed only after you approve.
Ask (mcp:orchestrator): ask_mybrain, a full answer synthesized over your brain with citations. It is rate limited and spends your plan quota.
Registry
server.json is the manifest published to the official MCP Registry as io.github.mybrain-ai/mcp.
Publishing (maintainers only) needs an Owner of the mybrain-ai org. The interactive mcp-publisher login github only grants the personal namespace (registry#1468); log in with a PAT instead (classic with read:org, or fine-grained with "Organization → Members → Read-only"), on mcp-publisher 1.8.1 or newer:
./mcp-publisher login github --token "$GH_PAT"./mcp-publisher publish
A published version is immutable, so every change to server.json ships with a new version.
