This repository demonstrates how to build a meeting preparation agent with real-time web access, leveraging Tavily's advanced search capabilities. This agent will connect to your Google Calendar via MCP, extract meeting information, and use Tavily search for profile research on the meeting attendees and general information on the companies you are meeting with.
The project is designed for easy customization and extension, allowing you to:
- Integrate proprietary or internal data sources
- Modify the agent architecture or swap out LLMs
- π Real-time Web Search: Instantly fetches up-to-date information using Tavily's search API.
- π§ Agentic Reasoning: Combines MCP and ReAct agent flows for smarter, context-aware responses.
- π Streaming Substeps: See agentic reasoning and substeps streamed live for transparency.
- π Citations: All web search results are cited for easy verification.
- ποΈ Google Calendar Integration: (via MCP) Access and analyze your meeting data.
- β‘ Async FastAPI Backend: High-performance, async-ready backend for fast responses.
- π» Modern React Frontend: Interactive UI for dynamic user interactions.
- π¬ Email Context (via iGPT): Adds internal-only email context for meeting prep.
- Backend (
backend/)agent.py: Agentic flow (MCP + LangChain-Tavily ReAct agent)
- Frontend (
ui/): React-based UI for meeting insights - Server (
app.py): FastAPI server for API endpoints and streaming
Python version: 3.13.2 (local development)
See google-calendar-mcp for full details.
Google Cloud Setup:
- Go to the Google Cloud Console and create/select a project.
- Enable the Google Calendar API.
- Create OAuth 2.0 credentials:
- Go to Credentials
- Click "Create Credentials" > "OAuth client ID"
- Choose "User data" for the type of data that the app will be accessing
- Add your app name and contact information
- Select "Desktop app" as the application type
- Add your email as a test user under the OAuth Consent screen.
- Create a file
gcp-oauth.keys.jsonin the root ofgoogle-calendar-mcpdirectory. - Download your credentials and paste them in
gcp-oauth.keys.json.
This file should look like:
{
"installed": {
"client_id": "<your-client-id>",
"project_id": "<your-project-id>",
"auth_uri": "<your-auth-uri>",
"token_uri": "<your-token-uri>",
"auth_provider_x509_cert_url": "<your-auth-provider>",
"client_secret": "<your-secret>",
"redirect_uris": ["http://localhost"]
}
}Install the MCP:
cd google-calendar-mcp
npm installSet config path:
GOOGLE_CALENDAR_CONFIG=<absolute-path-to-project>/mcp-use-case/google-calendar-mcp/build/index.jsRun the notebook mcp-test.ipynb to check that your MCP setup is working before proceeding.
By default, the agent prepares a meeting brief using public web research on attendees and the companies you are meeting with.
To ground the briefing in your real relationship with meeting attendees, enable iGPT. iGPT retrieves internal-only context from your connected email and returns meeting-relevant internal context passed into the LangGraph flow.
A typical enriched brief may include:
- What was last discussed with each attendee (internal threads)
- Commitments made by either side (and whatβs still pending)
- Open items / unresolved questions
The agent sends company and attendee information (derived from your Google Calendar events) to iGPT and asks it to retrieve relevant prior internal context.
Key rule enforced in the iGPT step:
- Internal sources only (no public web information)
You need two things:
IGPT_API_KEY(created in the Hub)IGPT_USER(theuservalue you choose inside the Playground)
- Go to: https://igpt.ai/hub/apikeys/
- Create a new key (treat this as a secret - do not share it)
You can still connect your email through the Playground, even if you donβt have an iGPT app yet.
- Open the Playground:
- Go to Connect Datasource
- Choose a
uservalue (this is your end-user identifier)- Example for a demo:
demo_user
- Example for a demo:
- Submit the request - the Playground will return an OAuth link
- Click the OAuth link and complete the login/consent
- Indexing will start for that
user
β
Important: The user value you used in Connect Datasource is the same value you must use later when calling iGPT (and what you should place in IGPT_USER).
In the Playground βAskβ screen (e.g. /v1/recall/ask) you will see a user field.
That value must match the one you used when connecting the datasource.
Set IGPT_USER to the exact same user value you used in the Playground:
IGPT_API_KEY=your-igpt-api-key
IGPT_USER=your-playground-user-valueLinks

- Create and activate a virtual environment:
python3 -m venv venv source venv/bin/activate # On Windows: .\venv\Scripts\activate
- Install dependencies:
python3 -m pip install -r requirements.txt
- Set environment variables:
export TAVILY_API_KEY="your-tavily-api-key" export OPENAI_API_KEY="your-openai-api-key" export GROQ_API_KEY="your-groq-api-key" export GOOGLE_CALENDAR_CONFIG="<absolute-path-to-project>/mcp-use-case/google-calendar-mcp/build/index.js"
- Run the backend server:
python app.py
- Navigate to the frontend directory:
cd ui - Install dependencies:
npm install
- Start the development server:
npm run start
.env file example:
TAVILY_API_KEY=your-tavily-api-key
OPENAI_API_KEY=your-openai-api-key
GROQ_API_KEY=your-groq-api-key
GOOGLE_CALENDAR_CONFIG=your-google-configPOST /api/analyze-meetings: Handles streamed LangGraph execution
