# MongoDB for Agent

> Store agent sessions and history in MongoDB with MongoDb.

`MongoDb` stores an Agent's sessions and run history in MongoDB.

## Usage

Provide either `db_url` or `db_client`. The default database name is `agno`; set `db_name` to use another database. The following example uses `db_url`.

Install the `agno`, `pymongo`, `openai`, and `ddgs` packages:

```shell theme={null}
uv pip install agno pymongo openai ddgs
```

### Run MongoDB

Install [Docker Desktop](https://docs.docker.com/get-started/get-docker/), then start MongoDB on port `27017`:

```bash theme={null}
docker run -d \
  --name local-mongo \
  -p 27017:27017 \
  -e MONGO_INITDB_ROOT_USERNAME=mongoadmin \
  -e MONGO_INITDB_ROOT_PASSWORD=secret \
  mongo
```

```python mongodb_for_agent.py theme={null}
from agno.agent import Agent
from agno.db.mongo import MongoDb
from agno.tools.websearch import WebSearchTools

db_url = "mongodb://mongoadmin:secret@localhost:27017"

db = MongoDb(db_url=db_url)

agent = Agent(
    db=db,
    tools=[WebSearchTools()],
    add_history_to_context=True,
)
agent.print_response("How many people live in Canada?")
agent.print_response("What is their national anthem called?")
```
