AI Agent for Food Bank Operations: Inventory Tracking, Distribution Scheduling, and Client Support

The Operational Complexity of Food Banks

Food banks operate under constant pressure: perishable inventory that must move quickly, clients with diverse dietary needs, regulatory requirements for food safety, and distribution schedules that need to accommodate working families. Many food banks rely on paper logs and spreadsheets to track thousands of pounds of food across multiple storage locations.

An AI operations agent can maintain real-time inventory awareness, schedule distribution appointments based on client eligibility and available stock, and flag items approaching expiration. This keeps food moving efficiently from donors to families while reducing waste.

Inventory Management Tool

The agent tracks what is in stock, flags expiring items, and helps plan distributions based on available supply.

from agents import function_tool

inventory: list[InventoryItem] = []

@function_tool
async def check_inventory(
    category: str = "all",
    include_expiring: bool = False,
) -> dict:
    """Check current food bank inventory levels."""
    results = []
    expiring = []

    for item in inventory:
        if category != "all" and item.category.value != category:
            continue
        entry = {"name": item.name, "category": item.category.value,
                 "quantity_lbs": item.quantity_lbs, "storage": item.storage_type.value}
        if item.expiration_date:
            days_left = (item.expiration_date - date.today()).days
            entry["expires_in_days"] = days_left
            if days_left <= 3:
                expiring.append(entry)
        results.append(entry)

    resp = {"items": results, "total_weight_lbs": sum(i.quantity_lbs for i in inventory)}
    if include_expiring:
        resp["expiring_within_3_days"] = expiring
    return resp

@function_tool
async def receive_donation(
    item_name: str,
    category: str,
    quantity_lbs: float,
    unit_count: int,
    donor_source: str,

Client Eligibility and Appointment Scheduling

Food banks typically allow visits on a set frequency. The agent checks eligibility and books appointments.

clients_db: dict[str, FoodBankClient] = {}
appointments_db: list[DistributionAppointment] = []

MAX_VISITS_PER_MONTH = 2
POUNDS_PER_PERSON = 5.0

@function_tool
async def check_eligibility(client_id: str) -> dict:
    """Check if a client is eligible for food assistance."""
    client = clients_db.get(client_id)
    if not client:
        return {"error": "Client not found. Please register first."}

    eligible = client.visits_this_month < MAX_VISITS_PER_MONTH
    allocation_lbs = client.household_size * POUNDS_PER_PERSON

    return {
        "client": client.household_name,
        "household_size": client.household_size,
        "visits_this_month": client.visits_this_month,
        "max_visits": MAX_VISITS_PER_MONTH,
        "is_eligible": eligible,
        "allocation_lbs": allocation_lbs,
        "dietary_restrictions": client.dietary_restrictions,
        "reason": "Eligible" if eligible else
            f"Monthly visit limit ({MAX_VISITS_PER_MONTH}) reached",
    }

@function_tool
async def schedule_appointment(
    client_id: str,
    preferred_date: str,
    preferred_time: str = "10:00 AM",
    special_requests: str = "",
) -> dict:
    """Schedule a food distribution appointment for an eligible client."""
    client = clients_db.get(client_id)
    if not client:
        return {"error": "Client not found"}

    if client.visits_this_month >= MAX_VISITS_PER_MONTH:
        return {"error": "Client has reached monthly visit limit"}

    allocation = client.household_size * POUNDS_PER_PERSON

    appt = DistributionAppointment(
        client_id=client_id,
        scheduled_date=date.fromisoformat(preferred_date),
        time_slot=preferred_time,
        estimated_weight_lbs=allocation,
        special_requests=special_requests,
    )
    appointments_db.append(appt)

    return {
        "status": "scheduled",
        "appointment_id": appt.appointment_id,
        "date": preferred_date,
        "time": preferred_time,
        "estimated_allocation_lbs": allocation,
        "household_size": client.household_size,
        "notes": special_requests or "None",
    }

Assembling the Food Bank Agent

FAQ

How does the agent handle perishable items close to expiration?

The agent's inventory check tool flags items within 3 days of expiration. When these are detected, the agent prioritizes distributing them in upcoming appointments and can suggest an emergency distribution event. The agent can also notify partner agencies that may accept near-expiration items for immediate use.

What happens when inventory runs low in a category?

Add a threshold alert tool that monitors category-level inventory. When any category drops below a configurable minimum (for example, 50 lbs of protein), the agent generates a notification for the food bank manager and can draft donation requests to regular supplier partners.

How do you handle clients who are not yet registered?

The agent detects unregistered clients when the eligibility check returns "not found." It then walks the caller through registration, collecting household name, size, address, phone, and dietary restrictions. After registration, the agent immediately checks eligibility and offers to schedule an appointment.
