Why use Ceven?

  1. AI native Npm integration

    • Describe the outcome and Ceven picks the right Npm calls, fills the parameters, and checks the result.
    • Structured, agent friendly tool schemas so each call runs reliably instead of by guesswork.
    • Rich coverage for reading, writing, and querying your Npm data, across all 12 of its actions.

  2. Managed auth

    • Built in OAuth with automatic token refresh and rotation.
    • One place to manage, scope, and revoke Npm access.
    • Per user and per environment credentials instead of shared keys.

  3. Agent optimized design

    • Actions are tuned from real success and error rates so reliability climbs over time.
    • Full execution logs so you always know what ran in Npm, when, and on whose behalf.
    • The agent pauses and asks when Npm is unclear instead of plowing ahead.

  4. Enterprise grade security

    • Fine grained access so you control which agents and people can reach Npm.
    • Least privilege by default, read scopes first and only the writes a workflow needs.
    • A full audit trail of every Npm action to support review and sign off.

Supported tools

Every action Ceven's agents can run on Npm, and when to use it.

Publish package
Use this when a build pipeline completes and you need to push a new version of a package to the registry.
Get package info
Pull metadata for a specific package including current version, maintainers, and dependencies.
List package versions
Retrieve all published versions of a package to identify the latest stable or beta release.
Search packages
Query the registry by keyword or name to find available libraries for a specific functionality.
Get package downloads
Pull download statistics for a package over a specific time window to measure adoption.
Deprecate package
Mark a specific version of a package as deprecated with a message explaining why.
Get user profile
Pull public profile information for a specific npm user including their published packages.
List organization packages
Retrieve all packages owned by a specific organization to audit internal library sprawl.
Update package version
Change the version tag of a package to promote a release candidate to production.
Remove package
Unpublish a package version from the registry. Use this for emergency removals of leaked secrets.
Get dependency tree
Pull the full tree of dependencies for a package to identify nested version conflicts.
Check package access

Frequently asked questions

Ceven uses personal access tokens to communicate with the npm registry. When you connect your account, you provide a token with the specific scopes required for the actions you want to automate, such as read only for auditing or write access for publishing. These tokens are stored using AES 256 encryption at rest and are never logged in plain text. The agent only injects the token into the request header when executing a specific action. You can rotate your token in the npm dashboard at any time, which will immediately stop all Ceven workflows until the new token is updated in the platform settings.
Yes. As long as the provided access token has the necessary permissions for your organization, the agent can publish to private scopes. This is commonly used in internal CI CD pipelines where the agent waits for a successful test suite run before calling the publish action. The agent can also manage access levels, ensuring that only specific team members can trigger the publish workflow. Because it supports scoped packages, you can maintain a strict separation between your open source contributions and your proprietary internal libraries while using the same workflow logic for both.
If the npm registry returns a 403 error because the version already exists, the agent catches this exception and triggers a failure event. Depending on how you built your workflow, the agent can either alert the developer via Slack or automatically attempt to bump the patch version and try the publish again. This prevents the pipeline from hanging and provides a clear audit trail of why the release failed. You can configure a retry policy that defines exactly how many times the agent should attempt a version increment before giving up and requesting human intervention.
Yes. Ceven is subject to the standard npm registry API rate limits. For most users, this is not an issue, but for organizations with thousands of packages, frequent polling can trigger a 429 Too Many Requests response. To handle this, the agent implements an exponential backoff strategy, meaning it will wait progressively longer between retries when it hits a limit. If you consistently hit these limits, we recommend switching from polling to a webhook based architecture where npm notifies Ceven of events, which significantly reduces the number of API calls required to keep your data in sync.
Ceven integrates with the npm audit API to pull known vulnerability data for your project. The agent can be scheduled to run a full audit every hour or every day. When a vulnerability is found, the agent doesn't just alert you; it can look for the minimum version that fixes the issue and draft a pull request to update your package.json file. This transforms security from a reactive manual process into a proactive automated one, ensuring that your production environment is always running the most secure versions of your third party code.
Ceven supports the primary npmjs registry and can be configured to work with private registry mirrors or proxies like Verdaccio or Artifactory. You simply provide the registry URL in the connection settings. The agent then directs all read and write actions to that specific endpoint instead of the default public registry. This is critical for enterprises that mirror packages internally for security or air gap reasons, allowing the agent to manage the internal mirror while still applying the same automation logic used for public packages.
The agent can perform read operations to list members and their roles within an organization to help with auditing. However, for security reasons, npm limits the ability to invite or remove members via the API for certain account types. Most member management still requires a manual action in the npm web dashboard. Ceven can bridge this gap by monitoring for member requests and alerting an admin, or by flagging accounts that have not been active for a long time so a human can manually revoke their access to the organization.
The agent uses the deprecate action to add a warning message to a package version. This is useful when a critical bug is found or when a library is being replaced by a new version. The agent can be set to deprecate old versions automatically based on a timeline, such as deprecating any version older than two major releases. When the action is triggered, npm will display the provided message to any user who attempts to install that version, effectively guiding your user base toward the supported version without breaking their existing builds immediately.
