If you want to create a tool or collaborate with others to create and maintain tools, you'll need to create a Tool Account.
This page will help you understand what a Tool Account is, the first steps to create a Tool Account/tool, and how to add and remove maintainers.
See Toolforge quickstart to set up and get started with Toolforge!
What is a Tool Account?
The Tool Account is a group account associated with a tool. The Tool Account can have one or more maintainers. You'll create a separate Tool Account for each new tool you develop on Toolforge, and you'll join an existing Tool Account when you're invited to work on or maintain the tool. A note about terms: Tool Accounts and tools are sometimes used interchangeably throughout Toolforge documentation.
Each Tool Account includes:
- A home directory on shared storage:
- The ability to run a Web service which is visible at
- Database access credentials:
$HOME/replica.my.cnf, which provide access to the production database replicas as well as to project-local databases
- Access to the continuous and task queues of the compute grid
- Credentials and a namespace for running containers on the Kubernetes cluster
People who have access to a Tool Account are called maintainers. Maintainers have access to the Tool Account's code and data.
- Create Tool Accounts/tools
- Join existing Tool Accounts/tools
- Leave Tool Accounts/tools in the care of others
- Sudo to the Tool Account/tools
Join an existing Tool Account
All Tool Accounts hosted in Toolforge are listed on the tools list.
Contact the maintainer to join an existing Tool Account.
Add or remove maintainers
To add or remove maintainers, use the 'manage maitainers' link found beneath the tool name on the Toolforge home page.
Create tools with Tool Accounts
Members of the ‘tools’ project can create tool accounts using toolsadmin:
- Go to https://toolsadmin.wikimedia.org/tools/
- Click on the "Tools" tab
- Click the "Create new tool" link at the bottom of the "Your tools" sidebar
- Follow the instructions in the Tool Account creation form
- Once the Tool Account is created, log off, then back in before you can access the new tool account
Name a Tool Account/tool
The Tool Account and tool will have the same name. This name will be included in the URL for the final Web service. Make sure the name is appropriate and is spelled correctly.
Note: Do not prefix the tool name with
tools.. This will cause problems during account creation.
Rename a Tool Account/tool
Tools can't be renamed. You can create a new tool with a new name and copy the code over from the old tool.
Switch to / become a Tool Account
maintainer@tools-login:~$ become <TOOL NAME> tools.toolname@tools-login:~$
Manage files in Toolforge
You can use
scp (or PuTTY) to copy files from your computer to Toolforge. To make files available to a tool account, copy or move them from your home directory to the tool's home directly:
yourshellaccountname@tools-login:~$ cp somefile ~tools.toolaccount/
Note that the tool account will have to
take ownership of the file before it can use it, see below.
Take ownership of files
take command allows you to change ownership of the file(s) and directories to the calling tool user.
The permissions of the file(s) before
take is run must include the tool user as either the owner or group. This prevents
take from being abused to take over arbitrary files.
To take ownership of files as your tool account:
become your Tool Account:
yourshellaccountname@tools-login:~$ become toolaccount tools.toolaccount@tools-login:~$
2. As your Tool Account,
take ownership of the files:
tools.toolaccount@tools-login:~$ take FILE
Mount your tools home directory onto your local machine
Modifying files on Toolforge servers may be difficult; after all, you are restricted to terminal-based editors. If you prefer to use modern IDEs such as Visual Studio Code, Eclipse, etc. you can mount the home directory of your tool onto your local Linux machine or virtual machine (VM).
First, create an empty directory on which you would mount the Toolforge remote directory. In the code examples below, it is assumed that you have created a local directory at
~/remote for this purpose.
To mount, use a command like this:
sshfs -o allow_other -o workaround=rename login.toolforge.org:/data/project/toolname ~/remote
allow_other option helps avoid permission issues, and the
workaround=rename option helps avoid issues with overwriting existing files.
You may receive a notice said:
fusermount3: option allow_other only allowed if 'user_allow_other' is set in /etc/fuse.conf; in such case, just uncomment line
user_allow_other in your
Remember to specify your Toolforge username if it's different from the one you have locally, i.e.
... email@example.com:/.... If it's wrong it will cause the generic error message:
read: Connection reset by peer
To unmount, use this command:
In certain situations, the above command may fail to work (e.g. network issues); if you need to forcefully unmount the network file system, you can use this command:
fusermount -zu ~/remote
Add a description to your Tool Account/Tool
Each tool can provide a description by creating a toolinfo record using https://toolsadmin.wikimedia.org/tools/.
$HOME/.description system is deprecated and will stop providing any benefit at some point in the future.
Delete a Tool Account
Maintainers can not delete Tool Accounts. You can delete the content of your directories and make an existing tool inaccessible by shutting down the Web service (
If you want to permanently delete a Tool Account, please follow the steps described at Toolforge (Tools to be deleted). It may take some time for the Tool Account to be deleted.
Troubleshoot a Tool Account
$ become <TOOL NAME> become: no such tool '<TOOL NAME>'
- Wait a few minutes for the Tool Account creation to complete.
- Check that the spelling of the tool name is correct.
$ become <TOOL NAME> You are not a member of the group tools.<TOOL NAME>. Any existing member of the tool's group can add you to that.
- If you are already logged in via SSH when you create a new tool, log out, and log in again to activate your new permissions.
Backup Toolforge data
There are no user-accessible backups in Toolforge.
You should use a source or version control tool to preserve your code and make regular backups of data. Learn more.
