Tool Repository

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 account
CrewAI CLI installed
uv>=0.5.0 installed. Check out how to upgrade
Git installed and configured
Access permissions to publish or install tools in your CrewAI AMP organization

Installing Tools

To install a tool:

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:

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”:

crewai tool install my-tool

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

crewai uv add requests

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

crewai uv sync

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:

crewai tool create <tool-name>

This generates a scaffolded tool project locally.

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

git init
git add .
git commit -m "Initial version"

To publish the tool:

crewai tool publish

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

crewai tool publish --public

For more details on how to build tools, see Creating your own tools.

Updating Tools

To update a published tool:

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

git commit -m "Update version to 0.1.1"
crewai tool publish

Deleting Tools

To delete a tool:

Go to CrewAI AMP
Navigate to Tools
Select the tool
Click Delete

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
