# Tool Repository

> Using the Tool Repository to manage your tools

## Overview

The Tool Repository is a package manager for CrewAI tools. It allows users to publish, install, and manage tools that integrate with CrewAI crews and flows.

Tools can be:

* **Private**: accessible only within your organization (default)
* **Public**: accessible to all CrewAI users if published with the `--public` flag

The repository is not a version control system. Use Git to track code changes and enable collaboration.

## Prerequisites

Before using the Tool Repository, ensure you have:

* A [CrewAI AMP](https://app.crewai.com) account
* [CrewAI CLI](/en/concepts/cli#cli) installed
* uv>=0.5.0 installed. Check out [how to upgrade](https://docs.astral.sh/uv/getting-started/installation/#upgrading-uv)
* [Git](https://git-scm.com) installed and configured
* Access permissions to publish or install tools in your CrewAI AMP organization

## Installing Tools

To install a tool:

```bash  theme={null}
crewai tool install <tool-name>
```

This installs the tool and adds it to `pyproject.toml`.

You can use the tool by importing it and adding it to your agents:

```python  theme={null}
from your_tool.tool import YourTool

custom_tool = YourTool()

researcher = Agent(
    role='Market Research Analyst',
    goal='Provide up-to-date market analysis of the AI industry',
    backstory='An expert analyst with a keen eye for market trends.',
    tools=[custom_tool],
    verbose=True
)
```

## Adding other packages after installing a tool

After installing a tool from the CrewAI AMP Tool Repository, you need to use the `crewai uv` command to add other packages to your project.
Using pure `uv` commands will fail due to authentication to tool repository being handled by the CLI. By using the `crewai uv` command, you can add other packages to your project without having to worry about authentication.
Any `uv` command can be used with the `crewai uv` command, making it a powerful tool for managing your project's dependencies without the hassle of managing authentication through environment variables or other methods.

Say that you have installed a custom tool from the CrewAI AMP Tool Repository called "my-tool":

```bash  theme={null}
crewai tool install my-tool
```

And now you want to add another package to your project, you can use the following command:

```bash  theme={null}
crewai uv add requests
```

Other commands like `uv sync` or `uv remove` can also be used with the `crewai uv` command:

```bash  theme={null}
crewai uv sync
```

```bash  theme={null}
crewai uv remove requests
```

This will add the package to your project and update `pyproject.toml` accordingly.

## Creating and Publishing Tools

To create a new tool project:

```bash  theme={null}
crewai tool create <tool-name>
```

This generates a scaffolded tool project locally.

After making changes, initialize a Git repository and commit the code:

```bash  theme={null}
git init
git add .
git commit -m "Initial version"
```

To publish the tool:

```bash  theme={null}
crewai tool publish
```

By default, tools are published as private. To make a tool public:

```bash  theme={null}
crewai tool publish --public
```

For more details on how to build tools, see [Creating your own tools](/en/concepts/tools#creating-your-own-tools).

## Updating Tools

To update a published tool:

1. Modify the tool locally
2. Update the version in `pyproject.toml` (e.g., from `0.1.0` to `0.1.1`)
3. Commit the changes and publish

```bash  theme={null}
git commit -m "Update version to 0.1.1"
crewai tool publish
```

## Deleting Tools

To delete a tool:

1. Go to [CrewAI AMP](https://app.crewai.com)
2. Navigate to **Tools**
3. Select the tool
4. Click **Delete**

<Warning>
  Deletion is permanent. Deleted tools cannot be restored or re-installed.
</Warning>

## Security Checks

Every published version undergoes automated security checks, and are only available to install after they pass.

You can check the security check status of a tool at:

`CrewAI AMP > Tools > Your Tool > Versions`
