GitHub

GitHub is a Git-based source code repository. You can use GitHub to share code with team members, track and manage changes to code over time, and collaborate on projects across your organization.

Integrating GitHub with Cortex allows you to:

• Automatically discover and track ownership of GitHub entities

• Follow a GitOps workflow with GitHub to manage your Cortex workspace

• View information about your GitHub repositories on an entity's details page, including: The repo associated with the entity, recent commits and releases in the event timeline, the most-used language in the files for that entity, the top code contributors, and their number of contributions.

  • In an entity's Code & Security section, see vulnerabilities from GitHub Advanced Security (Code scanning, Dependabot alerts, CodeQL, and Secret scanning)

• View information about pull requests and work items in the engineering homepage

• Use GitHub metrics in Eng Intelligence to understand key metrics and gain insight into services, incident response, and more

• Create Scorecards that track progress and drive alignment on projects involving your repositories

You can also optionally integrate GitHub Copilot with Cortex to:

• Track Copilot adoption and impact within Eng Intelligence

GitHub Copilot integration

If you installed the GitHub app prior to October 14, 2025, you must accept new permissions in order to access Copilot metrics in Cortex. See this KB article for more information.

How to configure GitHub with Cortex

Choose a configuration option

There are multiple options for connecting Cortex to your GitHub instance:

• Through Cortex's official GitHub app

  • Note: This is supported for use with a single organization in GitHub.

• Through a custom GitHub app

  • By using Cortex's official GitHub app or a custom GitHub app, users can tag entities with Git details and enable GitOps-style configuration of data in Cortex.

• Using a personal access token

• Using Cortex Axon Relay, a relay broker that allows you to securely connect your on-premises GitHub data.

If your GitHub setup involves multiple organizations, you can add multiple GitHub apps, use a personal access token that has access to all orgs, or create multiple configurations with corresponding aliases.

See the tabs below for instructions on each of the GitHub integration options.

If you're using a self-hosted instance of GitHub, you'll need to verify that your Cortex instance is able to reach the GitHub instance. We route our requests through a static IP address.

• Reach out to support at [email protected] to receive details about our static IP. If you're unable to directly allowlist our static IP, you can route requests through a secondary proxy in your network that has this IP allowlisted and have that proxy route traffic to your GitHub instance.

Cortex GitHub app

Configure GitHub with the Cortex GitHub app

Cortex's official GitHub app is the easiest way to connect your GitHub instance. It is preconfigured with the permissions needed to use this integration. Note that it is not available for Cortex Server.

To set up the app:

1. In Cortex, navigate to the GitHub settings page:

   1. Click Integrations from the main nav. Search for and select GitHub.

2. On the GitHub settings page, next to cortex, click Install.

3. Follow the prompts, then click Install & Authorize.

Cortex's GitHub app is preconfigured with:

• Permissions for catalogs, Scorecards, and the Scaffolder.

• Webhooks to enable GitOps.

• Support for using GitHub teams as an ownership provider.

The app comes with a built-in linter, which validates the format of a given cortex.yaml file and checks Cortex-specific items. However, the linter DOES NOT validate data correctness. For example, the linter will confirm that the format of a group block is correct, but will not check that the group exists.

Custom app

Personal access token

Relay broker

Configure the integration for multiple GitHub accounts​

The GitHub integration has multi-account support. You can add a configuration for each additional organization, instance, or account by repeating the process above.

Each configuration requires an alias, which Cortex uses to correlate the designated organization, instance, or account with registrations for various entities. Registrations can also use a default configuration without a listed alias. You can edit aliases and default configurations from the GitHub page in your Cortex settings. Select the edit icon next to a given configuration and toggle Set as default on. If you only have one configuration, it will automatically be set as the default.

Cortex supports mapping multiple identities for a single user if you have multiple configurations of GitHub. See the Identity mapping documentation for more information.

To write rules related to Dependabot alerts, you must verify the necessary permissions are set for repositories you'd like to see vulnerabilities reported on.

To verify, navigate to a repository on GitHub and click "Settings" → "Code security and analysis". Make sure you are a member of a team under "Access to alerts.

Registration

See the Create services documentation for instructions on importing entities.

Entity descriptor

Repository

You can define a GitHub repository for a given entity by adding the x-cortex-git block to the entity's descriptor. When you define a repository, Cortex checks for Security Advisory vulnerabilities from the GraphQL API and Advanced Security vulnerabilities from the Rest API.

x-cortex-git:
  github:
    repository: cortex/docs
    basepath: myService
    alias: myApp

Field	Description	Required
repository	GitHub repository in the form /	✓
basepath	Subdirectory for the entity if it is in a monorepo. Note that setting a basepath filters the vulnerabilities that appear in Cortex; Advanced Security vulnerabilities will not appear.
alias	Alias for the configuration in Cortex (only needed if you have opted into multi-account support)

Only one repository can be defined for in a given entity's YAML in the x-cortex-git block. Users looking to list additional repositories without the full functionality of GitOps can define the repos as custom data.

x-cortex-custom-metadata:
  second-git-repo:
    - `/`
  third-git-repo:
    - `/`

Ownership

You can define the following block in your Cortex entity descriptor to add your GitHub teams. Be sure to include both your GitHub organization name and the team name in the name field.

x-cortex-owners:
  - type: group
    name: cortex/engineering
    provider: GITHUB
    description: This is a description for this GitHub team that owns this entity.

Field	Description	Required
type	Ownership type; must be defined as group for GitHub teams	✓
name	GitHub team name in the form /Team names are generally converted to lowercase with - separators (Team Name would be cortex/team-name), but you can verify your exact name from the GitHub permalink	✓
provider	Name of integration (in this case, GITHUB)	✓
description	Description for the GitHub team

Multiple GitHub organizations are not supported for ownership, and Cortex will use the default configuration when fetching teams.

Identity mappings

Cortex maps users' email addresses to discovered GitHub accounts, so you never need to define email ownership in an entity descriptor. Users must be members of GitHub teams to be pulled in to Cortex.

You can confirm users' GitHub accounts are connected from GitHub identity mappings in settings.

Using the GitHub integration

View GitHub data on entity pages in Cortex

The GitHub integration will populate the Repo and Language detail blocks on an entity's details page. If a GitHub team has been defined as the owner for an entity, it will also appear in the Owners block.

Code & security

Vulnerabilities appear in the Vulnerabilities block under Code & security on an entity page overview.

Click Code & security in an entity's sidebar to view the full list of vulnerabilities for an entity. Cortex checks for:

• Security Advisory vulnerabilities from the GraphQL API

• GitHub Advanced Security vulnerabilities

  • Cortex pulls data from code scanning, Dependabot alerts, CodeQL, and Secret scanning.

  • Dependency reviews are not supported.

GitHub Advanced Security vulnerabilities are not surfaced for monorepos.

You can query for vulnerabilities with CQL and create Scorecard rules based on security metrics. See Scorecards and CQL below.

Events

Recent commits appear at the top of an entity's overview page.

You can also click Events in the entity's sidebar to see all commits and releases associated with that entity. Each is hyperlinked to the commit or release page in GitHub and includes a timestamp.

Repository

You can access more detailed information pulled from GitHub in the Repository page in the sidebar. At the top of the page, you'll find the repo(s) associated with that entity and the most-used language in files for that entity. In the Top contributors block, you'll find the three users who have contributed the most code and the number of their contributions.

In the Commits section, you'll find the 10 most recent commits and metadata about each. Below Commits is the Recent releases section, which includes the 5 most recent releases.

Issue tracking

From the Issue tracking page in the entity's sidebar, you can find a list of open GitHub issues. Each issue will show the number, title, assignees, and date created.

Packages

Packages are automatically scraped from your Git repos or they can be submitted via the packages API. The package file must be in the root of your repository — or, if you're using basepath, in the root of the subdirectory — to be scraped by Cortex. You can query an entity's packages in CQL explorer using packages().

To view packages, click Packages in the entity's sidebar.

The following package types are automatically scraped from repositories:

• JavaScript / Node.js: package.json, package-lock.json, yarn.lock, pnpm-lock.yaml

• Python: requirements.txt, pipfile.lock

• .NET (C#): packages.lock.json

• Java: pom.xml

• Go: go.sum

All other files of these types can be added via the packages API.

CI/CD - GitHub workflows

From the CI/CD > GitHub workflows page in the entity's sidebar, you can find a history of GitHub workflow runs for the past week. Each run is tagged with its status: IN_PROGRESS, COMPLETED, SUCCESS, CANCELLED, FAILURE, PAUSED.

The GitHub workflows page displays data about workflows in GitHub, not Workflows initiated via Cortex's Workflows tool.

Team entity pages

When a GitHub team is registered with a team entity, Cortex will pull GitHub users in to the Members tab. When available, Cortex will pull in the profile picture and email address for each user.

Engineering homepage

The GitHub integration enables Cortex to pull information about pull requests and issues into the homepage. You can find your open pull requests, any pull requests assigned to you for review, and any issues assigned to you.

Pull requests and issues from GitHub are refreshed every 2 minutes.

Eng Intelligence

The Eng Intelligence tool uses pull request data from GitHub to generate metrics:

• Average PR open to close time

• Avg time to first review

• Avg time to approval

• PRs opened

• Weekly PRs merged

• Avg PRs reviewed/week

• Avg commits per PR

• Ave lines of code changed per PR

Eng Intelligence also pulls in data from Copilot to show AI impact in the Copilot Dashboard.

You can read more about how Eng Intelligence tracks metrics for teams and users in the Eng Intelligence documentation.

To add deployments for your Github related entity, you can send a deployment event to the Cortex API.

Scorecards and CQL

With the GitHub integration, you can create Scorecard rules and write CQL queries based on GitHub data.

See more examples in the CQL Explorer in Cortex.

Approvals required to merge

Number of approvals required to merge a pull/merge request into a repository. Defaults to 0 if no approvals are defined.

Definition: git.numOfRequiredApprovals()

Examples

For a security or development maturity Scorecard, you can write a rule to make sure at least one approval is required to merge a pull/merge request:

git.numOfRequiredApprovals() > 0

By having a rigorous PR process in place for a repo, you can make sure changes aren't made that create vulnerabilities. This kind of rule could also be used in a best practices or project standards Scorecard.

You can also use a similar expression in the Query Builder to find entities lacking approval:

git.numOfRequiredApprovals() < 1

Git repository set

Check if an entity has a registered Git repository.

Definition: git (==/!=) null: Boolean

Example

In a Scorecard, you can write a rule that detects whether an entity has a Git repository set:

git != null

Branches

List all live branches with some basic metadata.

• Head

• Is protected

• Name

Definition: git.branches()

Example

For a best practices Scorecard, you can make sure that branches associated with an entity match a standard naming convention:

git.branches().all((branch) => branch.name.matches("(main|master|feat-.*|bug-.*|task-.*)"))

Branch protection details

Find details for specified branch, or default branch if none is specified.

• Branch name

• Code owner reviews required

• Dismiss stale reviews

• Required status checks

• Restrictions apply to admin

• Review required

Definition: git.branchProtection()

Examples

For a security Scorecard, you can write a rule to make sure the default branch is protected:

git.branchProtection() != null

Because vulnerabilities in the default branch are critical, this rule should be in one of the first couple levels.

You can also use the Query Builder to find entities with unprotected default branches:

git.branchProtection() = null

Commits

Get the latest commits (to a maximum of 100) for a defined lookback period (defaulting to 7 days).

• Date

• Message

• SHA

• URL

• Username

These results can be filtered based on branch name, using the default branch if no other branch is provided.

Definition: git.commits()

Example

You can use the git.commits() expression in a security Scorecard to make sure entities have fewer than three commits to a "security-fixes" branch in the last week:

git.commits(branchName="security-fixes").length < 3

Entities passing this rule will include those that haven't needed three or more security fixes. This can indicate that there aren't vulnerabilities in a given entity's code, but could also suggest that fixes aren't being implemented. Using this rule in conjunction with one focused on vulnerabilities could provide the extra context needed to gain a better understanding of what's happening.

Default branch

Default branch for the repository, or main when null.

Definition: git.defaultBranch()

Example

If default branches should always be named "main," you can write a rule to make sure entities follow this practice:

git.defaultBranch().matches("main")

File contents

Load the contents of a file from the entity's associated repository.

The contents can be validated by using string comparison operations or parsed by the built-in jq function. The jq function will automatically coerce file contents of JSON or YAML formats.

Definition: git.fileContents()

Example

For a Scorecard focused on development maturity, you could use the git.fileContents() rule to enforce that a CI pipeline exists, and that there is a testing step defined in the pipeline.

git.fileContents("circleci/config.yml").matches(".*npm test.*")

A best practices Scorecard, meanwhile, could use this expression for a number of rules:

• To make sure node engine version in specified in the package.json file:

  jq(git.fileContents("package.json"), ".engines.node") != null

• To make sure TypeScript projects have a tsconfig.json file checked in:

  jq(git.fileContents("package.json"), ".devDependencies | with_entries(select(.key == \"typescript\")) | length") == 0 or git.fileExists("tsconfig.json")

• To make sure projects using yarn do not allow NPM:

  jq(git.fileContents("package.json"), ".engines.yarn") == null or jq(git.fileContents("package.json"), ".engine.npm") = "please-use-yarn"

• And to ensure the yarn version being used is not deprecated:

  jq(git.fileContents("package.json"), ".engines.yarn") == null or !(semver("1.2.0") ~= semverRange(jq(git.fileContents("package.json"), ".engines.yarn")))

File exists

Check if file exists from within the entity's associated repository.

Definition: git.fileExists()

Examples

For a Scorecard focused on best practices, you can make sure that repositories contain a README.md file:

git.fileExists("README.md")

This rule would make sense in the first level because it's so essential.

A higher-level rule in a best practices Scorecard might confirm that developers are checking in lockfiles to ensure consistency in package installs:

git.fileExists("yarn.lock") OR git.fileExists("package-lock.json")

And/or a rule that makes sure there are unit tests enabled:

git.fileExists("*Test.java")

Finally, you could write a rule to make sure projects have a standard linter:

git.fileExists(".prettierrc.json") OR git.fileExists(".eslintrc.js")

Number of Git vulnerabilities

Check the number of vulnerabilities for an entity's associated repository.

You can filter by severity (by default searches by all severities) or source (by default only searches GitHub security advisories).

When using the GitHub Advanced Security source, severities displayed in the UI may not match severities returned by the API.

Definition: git.numOfVulnerabilities()

Examples

A security-focused Scorecard will likely include a rule making sure there are no Git vulnerabilities:

git.numOfVulnerabilities() == 0

You can use Scorecard levels to stratify vulnerabilities by risk. An initial level might make sure there are no critical vulnerabilities:

git.numOfVulnerabilities(severity=["CRITICAL"]) == 0

While a higher level might make sure there are no vulnerability warnings:

git.numOfVulnerabilities(severity=["WARNING"]) == 0

List of Git vulnerabilities

Lists the vulnerabilities for an entity's associated repository. You can filter by severity (by default searches by all severities) or source (by default only searches GitHub security advisories). Note when using the GitHub Advanced Security source, severities displayed in the UI may not match severities returned by the API.

Definition: git.vulnerabilities()

Examples

You could write a Scorecard rule that verifies an entity has fewer than 5 Git vulnerabilities:

git.vulnerabilities().length < 5

You could write a rule that verifies the entity has no vulnerabilities with "High" or "Critical" severity sourced from GitHub Advanced Security:

git.vulnerabilities(severity=["CRITICAL", "HIGH"], source=["GITHUB_ADVANCED_SECURITY"]).length < 1

Has Cortex YAML

Check if a repository has a valid cortex.yaml file checked in at the root directory (when GitOps is enabled).

Definition: git.hasCortexYaml()

Example

If you're using a Scorecard to track a migration from Cortex UI to GitOps, you can use this rule to make sure entities are set up for GitOps management of entity descriptors:

git.hasCortexYaml() == true

Last commit details

Provides last commit details.

• Date

• Message

• SHA

• URL

• Username

Definition: git.lastCommit()

Examples

One of the first rules you might write for a Scorecard focused on development maturity or security is one validating that the last commit was within the last month:

git.lastCommit().freshness < duration("P1M")

As counterintuitive as it may seem, services that are committed too infrequently are actually at more risk. People who are familiar with the service may leave a team, institutional knowledge accumulates, and from a technical standpoint, the service may be running outdated versions of your platform tooling.

Depending on best practices at your organization, you may want to confirm entities are updated within a week:

git.lastCommit().freshness < duration("P7D")

Confirming whether a service was updated within the last week can help team members catch outdated code sooner. Plus, if there is a security issue, you can quickly determine which services have or have not been updated to patch the vulnerability.

Pull requests

Lists pull requests opened during a defined lookback period.

• Approval date

• Author

• Date closed

• Date opened

• First review date

• Last updated

• Number of commits

• Number of lines added

• Number of lines deleted

• Organization

• Repository

• Source

• Status

• URL

Definition: git.pullRequests()

Example

You can use the git.pullRequests() query to find entities that have a small number of pull requests opened in the last two weeks:

git.pullRequests(lookback=duration("P14D")).length < 3

This can highlight entities that haven't been updated recently, which may be especially useful when entities have to be updated to address a vulnerability.

Reviews

List reviews left during a defined lookback period.

• Organization

• Repository

• Review date

• Reviewer

Definition: git.reviews()

Examples

A development maturity Scorecard might use the git.reviews() expression to make sure that there is a rigorous review process in place before changes are implemented:

git.reviews(lookback=duration("P7D")).length > 25

This rule makes sure that there are more than 25 reviews left in the last week.

Workflow runs

Get workflow runs meeting given filter criteria, including conclusions, statuses, and a lookback period.

• Conclusion

• Name

• Run started at

• Run time

• Run updated at

• Status

Conclusions: FAILURE, SUCCESS, TIMED_OUT

Statuses: QUEUED, IN_PROGRESS, COMPLETED

The lookback period specifies a duration for which returned runs should be created within, defaulting to a period of 3 days.

• The runTime of the WorkflowRun object represents the difference between runStartedAt and runUpdatedAt times in seconds.

Definition: git.workflowRuns()

Example

To make sure an entity has had a successful workflow run within the last two weeks, you can write a rule like:

git.workflowRuns(conclusions=["SUCCESS"], statuses=["COMPLETED"], lookback=duration("P14D")).length > 0

This rule is checking for GitHub workflow runs with a SUCCESS conclusion and COMPLETED status during a 14-day lookback window.\

To find the percentage of successes in workflow runs, you could write a query similar to:

(git.workflowRuns(conclusions=["SUCCESS"], lookback=duration("P1D")).length) / (git.workflowRuns(lookback=duration("P1D")).length) * 100

Ownership CQL

All ownership details

A special built-in type that supports a null check or a count check, used to enforce ownership of entities.

Definition: ownership: Ownership | Null

Example

An initial level in a security Scorecard might include a rule to ensure an entity has at least one team as an owner:

ownership.teams().length > 0

All owner details

List of owners, including team members and individual users, for each entity

Definition: ownership.allOwners()

Example

The Scorecard might include a rule to ensure that entity owners all have an email set:

ownership.allOwners().all((member) => member.email != null)

Team details

List of teams for each entity

Definition: ownership.teams(): List<Team>

Example

The Scorecard might include a rule to ensure that an entity owners all have a description and are not archived:

ownership.teams().all(team => team.description != null and team.isArchived == false)

External repositories

By default, each GitHub rule is evaluated on the repository defined in a given entity descriptor. If the base path parameter has been set, CQL rules will automatically scope to the base path subdirectory.

To evaluate the rule for a service for an external repository, pass the repo identifier in the git(repoIdentifier: Text) command (e.g. git("github:org/repositoryName")).

This can be combined with other CQL rules. For example, a rule based on a dynamic external repository with custom data would be git("github:" + custom("my-custom-repo")).fileExists("README.md").

View integration logs

This feature is available to Cortex cloud customers.

On the integration settings page, click the Logs tab to view logs from the last 7 days. Learn more in Troubleshooting with integration logs.

Background sync

Cortex conducts a background sync of GitHub identities every day at 10 a.m. UTC. Pull requests and issues are refreshed about every 10 minutes.

FAQs and troubleshooting

I'm getting this error: "{"message":"Not Found", "documentation_url":"https://docs.github.com/rest/repos#get-a-repository"}".

If you've set up multiple GitHub accounts/organizations, Cortex will not be able to identify the correct one unless the alias variable is defined.

What if I have multiple email addresses set in my GitHub account?

Cortex will only detect the primary email address associated with your GitHub account if it is public.

If Cortex is not correctly pulling in user emails, ensure the given user(s) have allowed their email address to be public. Make sure the "Keep my email address private" setting is unchecked in the user's personal GitHub settings.

My ownership isn't being automatically mapped through GitHub.

If the email address associated with your Cortex account is not the same as your GitHub email address, you need to add your Cortex email address to the Public email dropdown in GitHub settings.

Github OAuth, which you can configure in Cortex user settings, allows you to link your GitHub username with your Cortex account, even if you don't have a public email set up on GitHub.
