We released the first version of the Pivotal Tracker API a couple of months ago, and already there is a growing list of useful 3rd party tools out there:
Pivotal Tracker for Ruby
This is a ruby wrapper for the API, written by our friends at Mobile Commons.

Email Integration
Also from Mobile Commons, this tool allows your to automatically create Tracker stories from inbound emails.

GitHub Post Receive Hook
This is web service that you run on your own server, written by Chris Bailey. It automatically updates stories in your project(s) based on GitHub commit comments:

Pickler
Synchronize stories in Pivotal Tracker with Cucumber features. If you haven't heard of it yet, Cucumber is a really cool app that can execute plain-text documents as automated functional tests.

More Tools
There are more, most of them live in GitHub:

If you have written something you'd like to share, or know of other useful tools, let us know! Also, we're planning on making the API better, and would love your feedback.
Great article comparing Pivotal Tracker to Mingle, as an example of a tool that simplifies things, rather than trying to manage complexity (and getting in the way):
Agile Tool Vendors: Please don’t try to manage complexity - simplify my life!
Thanks for the positive feedback, Matthias!
Chris Bailey wrote a GitHub post receive hook for Tracker, using the API. It's a web service that you run on your own server, and it automatically updates stories in your project(s) based on commit comments. Check out his blog post here. Thanks for spending your Thanksgiving on this, Chris.
Let us know if you find this useful, we're definitely interested in making integration with other apps easier, and would love specific ideas and suggestions.
