# Brain Attic MCP server

> Read and write a shared, governed team knowledge base from your AI agent, with per-user access and search.

- Listing: https://mcp.tc/i/brain-attic
- Connect: use the server's own URL `https://app.brainattic.ai/api/mcp` (OAuth sign-in at the server); clients connect to it directly. The listing link is a page, not an MCP endpoint.
- Type: remote (Streamable HTTP)
- Auth: OAuth sign-in
- Category: [Docs & Knowledge](https://mcp.tc/c/docs-knowledge)
- Vendor: Finite Software Systems Ltd
- Homepage: <https://app.brainattic.ai/>

## About

Brain Attic is a multi-tenant knowledge base that AI agents can read from and write to. It acts as a shared memory for a team and the agents working alongside them, with search to find the right content.

The server runs as a hosted streamable HTTP endpoint at app.brainattic.ai. Users authenticate per user through OAuth, and access is scoped to their tenant. A Brain Attic workspace is needed.

## What it can do

- Search a shared team knowledge base
- Read stored knowledge from your agent
- Write new knowledge for the team
- Tenant-scoped, per-user access

## Example prompts

- "Search our Brain Attic knowledge base for the onboarding process."
- "Save these meeting notes to our team knowledge base."
- "What does our knowledge base say about the deployment checklist?"

## Install

### Claude Code

1. Run this in a terminal, in your project folder:

```bash
claude mcp add --transport http brain-attic https://app.brainattic.ai/api/mcp
```

2. Start Claude Code, type `/mcp`, pick **brain-attic** and choose **Authenticate**. A browser window opens for the Finite Software Systems Ltd sign-in.

Add `--scope user` to make it available in every project, not just this one.

### Claude Desktop

1. Open **Customize → Connectors**, click **+ Add**, then **Add custom connector**.

2. Name it **Brain Attic** and paste this URL:

```url
https://app.brainattic.ai/api/mcp
```

3. Click **Add**, then **Connect**, and sign in when Finite Software Systems Ltd asks.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

### claude.ai

1. Open the connector form on claude.ai. This button fills in the name and URL for you:

[Add to claude.ai](<https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Brain%20Attic&connectorUrl=https%3A%2F%2Fapp.brainattic.ai%2Fapi%2Fmcp>) (opens connector settings)

2. Check that the URL reads `https://app.brainattic.ai/api/mcp` and click **Add**.

3. Click **Connect** and sign in when Finite Software Systems Ltd asks.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under **Organization settings → Connectors**.

### ChatGPT

1. On chatgpt.com, go to **Plugins**, select **+**, then **Add custom MCP server**.

2. Enter a name for the server.

3. Under **Connection**, paste `https://app.brainattic.ai/api/mcp` as the server URL, then for authentication choose **OAuth**. ChatGPT sends you to Finite Software Systems Ltd to sign in.

4. Check **I understand and want to continue**, then select **Create as a plugin**.

Whether you can add a custom MCP server depends on your ChatGPT plan and your workspace permissions (in Business workspaces, admins and owners can).

### Cursor

[Add to Cursor](<https://cursor.com/install-mcp?name=brain-attic&config=eyJ1cmwiOiJodHRwczovL2FwcC5icmFpbmF0dGljLmFpL2FwaS9tY3AifQ%3D%3D>) (opens Cursor)

Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):

`mcp.json`:

```json
{
  "mcpServers": {
    "brain-attic": {
      "url": "https://app.brainattic.ai/api/mcp"
    }
  }
}
```

Cursor shows **Needs authentication** next to the server. Click the button beside it to sign in.

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=brain-attic&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fapp.brainattic.ai%2Fapi%2Fmcp%22%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"brain-attic","type":"http","url":"https://app.brainattic.ai/api/mcp"}'
```

Or commit it to the repo in `.vscode/mcp.json`:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "brain-attic": {
      "type": "http",
      "url": "https://app.brainattic.ai/api/mcp"
    }
  }
}
```

VS Code asks you to sign in the first time the server starts.

### Devin Desktop

1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows):

`mcp_config.json`:

```json
{
  "mcpServers": {
    "brain-attic": {
      "serverUrl": "https://app.brainattic.ai/api/mcp"
    }
  }
}
```

2. Refresh the MCP server list in Cascade and sign in when asked.

Devin Desktop is the new name for Windsurf. It reads `serverUrl` (or `url`) for remote servers.

### Codex

```bash
codex mcp add brain-attic --url https://app.brainattic.ai/api/mcp
codex mcp login brain-attic
```

Or edit `~/.codex/config.toml` directly:

`config.toml`:

```toml
[mcp_servers.brain-attic]
url = "https://app.brainattic.ai/api/mcp"
```

### Gemini CLI

```bash
gemini mcp add --transport http brain-attic https://app.brainattic.ai/api/mcp
```

Then, inside Gemini CLI, run `/mcp auth brain-attic` to sign in.

This adds it to the current project. Add `-s user` to use it everywhere.

### Any client

Most clients accept this shape. Some name the URL field differently: `serverUrl` in Devin Desktop, `httpUrl` in Gemini CLI’s settings file.

```json
{
  "mcpServers": {
    "brain-attic": {
      "type": "http",
      "url": "https://app.brainattic.ai/api/mcp"
    }
  }
}
```

Zed puts servers under `context_servers` in its settings. Cline needs `"type": "streamableHttp"`, or it assumes SSE.

Client only starts local servers? Bridge it with `npx -y mcp-remote https://app.brainattic.ai/api/mcp`.
