OpenAI Apps & MCP Apps Support

▶️ Click to watch the demo video

There is now support for OpenAI Apps and MCP Apps in this MCP Server. When UI mode is enabled for each tool there is a corresponding UI widget that let's you control what gets added to the model's context. See the directions in usage with ChatGPT section.

Configuration

Getting an API Key

Sign up for a Brave Search API account
Choose a plan
Generate your API key from the developer dashboard

Streamable HTTP mode

By default the MCP server runs in stdio mode.

BRAVE_API_KEY="your_key_here" npx -y brave-search-mcp

To enable Streamable HTTP mode:

BRAVE_API_KEY="your_key_here" npx -y brave-search-mcp --http

By default the server listens on port 3001. The URL is:

http://0.0.0.0:3001/mcp

Environment variables

When running in HTTP mode, the following environment variables are supported:

BRAVE_API_KEY (required): Brave Search API key.
PORT (optional): HTTP port (default: 3001).
HOST (optional): Interface to bind to (default: 0.0.0.0).
ALLOWED_HOSTS (optional): Comma-separated list of allowed hostnames for Host header validation.
- Example: ALLOWED_HOSTS=localhost,127.0.0.1,my-app.ngrok-free.app
- Use hostnames only (no scheme/path), e.g. my-app.ngrok-free.app not https://my-app.ngrok-free.app/mcp

Examples:

# Local only
HOST=127.0.0.1 ALLOWED_HOSTS=localhost,127.0.0.1 BRAVE_API_KEY="your_key_here" npx -y brave-search-mcp --http

# Local with ngrok tunnel
HOST=127.0.0.1 ALLOWED_HOSTS=localhost,127.0.0.1,my-app.ngrok-free.app BRAVE_API_KEY="your_key_here" npx -y brave-search-mcp --http --ui

Usage with ChatGPT

The Brave Search MCP Server can be used with the web UI of ChatGPT. It takes a few steps.

1. Enable Developer Mode in ChatGPT

Settings → Apps → Advanced settings → Developer mode

Additional instructions here

2. Run the Brave Search MCP in HTTP mode and UI mode

BRAVE_API_KEY="your_key_here" npx -y brave-search-mcp --http --ui

3. Create a local tunnel to expose the MCP Server to ChatGPT

ngrok http 3001

Take note of the forwarding URL.

...
Forwarding                    https://john-joe-asdf.ngrok-free.dev -> http://localhost:3001
...

4. Add Brave Search MCP as a Connector to ChatGPT

Open ChatGPT Apps settings

Click Apps

Click Create Apps

Fill out the form using the URL from step 3 as the MCP Server URL, but add /mcp.

https://john-joe-asdf.ngrok-free.dev/mcp

For Authentication, select 'No Auth'

Tick the checkbox for 'I understand and want to continue'

Then click Create.
