# MongoDB Vector Database

> Use MongoDB as a vector database for your Knowledge Base.

## Setup

Follow the instructions in the [MongoDB Setup Guide](https://www.mongodb.com/docs/atlas/getting-started/) to get connection string

Install MongoDB packages

```shell theme={null}
uv pip install "pymongo[srv]"
```

## Example

```python agent_with_knowledge.py theme={null}
from agno.agent import Agent
from agno.knowledge.knowledge import Knowledge
from agno.vectordb.mongodb import MongoVectorDb

# MongoDB Atlas connection string
"""
Example connection strings:
"mongodb+srv://<username>:<password>@cluster0.mongodb.net/?retryWrites=true&w=majority"
"mongodb://localhost/?directConnection=true"
"""
mdb_connection_string = ""

knowledge_base = Knowledge(
    vector_db=MongoVectorDb(
        collection_name="recipes",
        db_url=mdb_connection_string,
        wait_until_index_ready_in_seconds=60,
        wait_after_insert_in_seconds=300
    ),
)  # adjust wait_after_insert_in_seconds and wait_until_index_ready_in_seconds to your needs

if __name__ == "__main__":
    knowledge_base.insert(
        url="https://agno-public.s3.amazonaws.com/recipes/ThaiRecipes.pdf"
    )

    agent = Agent(knowledge=knowledge_base)
    agent.print_response("How to make Thai curry?", markdown=True)
```

<Card title="Async Support ⚡">
  <div className="mt-2">
    <p>
      MongoDB also supports asynchronous operations, enabling concurrency and leading to better performance.
    </p>

    ```python async_mongodb.py theme={null}
    import asyncio

    from agno.agent import Agent
    from agno.knowledge.knowledge import Knowledge
    from agno.vectordb.mongodb import MongoVectorDb

    # MongoDB Atlas connection string
    """
    Example connection strings:
    "mongodb+srv://<username>:<password>@cluster0.mongodb.net/?retryWrites=true&w=majority"
    "mongodb://localhost:27017/agno?authSource=admin"
    """
    mdb_connection_string = "mongodb+srv://<username>:<password>@cluster0.mongodb.net/?retryWrites=true&w=majority"

    knowledge_base = Knowledge(
        vector_db=MongoVectorDb(
            collection_name="recipes",
            db_url=mdb_connection_string,
        ),
    )

    # Create and use the agent
    agent = Agent(knowledge=knowledge_base)

    if __name__ == "__main__":
        # Load knowledge base asynchronously
        asyncio.run(knowledge_base.ainsert(
                url="https://agno-public.s3.amazonaws.com/recipes/ThaiRecipes.pdf"
            )
        )

        # Create and use the agent asynchronously
        asyncio.run(agent.aprint_response("How to make Thai curry?", markdown=True))
    ```

    <Tip className="mt-4">
      Use <code>aload()</code> and <code>aprint\_response()</code> methods with <code>asyncio.run()</code> for non-blocking operations in high-throughput applications.
