Manage Heroku apps from an assistant: create and deploy apps, scale and restart dynos, read logs, manage add-ons and pipelines, and run Heroku Postgres queries.
- Maintained by
- Heroku
- Hosting
- Runs locally on your machine
- Authentication
- API key or credentials (environment variables)
- Last checked
Requires the Heroku CLI v10.8.1 or later installed globally; `heroku mcp:start` can be used instead of an API key.

}Frequently asked questions
What is the Heroku MCP server?
It is a Model Context Protocol (MCP) server — a small piece of software that gives AI assistants like Claude a secure, governed connection to Heroku. Manage Heroku apps from an assistant: create and deploy apps, scale and restart dynos, read logs, manage add-ons and pipelines, and run Heroku Postgres queries.
Is there an official Heroku MCP server?
Yes. The Heroku MCP server is an official integration, maintained by the vendor or the Model Context Protocol project, which makes it the safest default for business use. It is maintained by Heroku.
Is the Heroku MCP server hosted, or do I run it myself?
It runs locally. Your AI client starts it on your own machine with npx, and it talks to the client over standard input and output rather than the network.
Do I need an API key for the Heroku MCP server?
Yes. The local server reads HEROKU_API_KEY from its environment, so you create that credential first and add it to your client's config.
What can an AI assistant actually do with Heroku?
Through this server an assistant can work with manage apps, scale dynos, view logs, manage add-ons, heroku postgres — reading from and acting on Heroku directly instead of you copy-pasting between windows. What you allow it to do is controlled by the permissions you grant.
How do I set this up for my business?
The setup section above has copy-paste config for Claude Code, Claude Desktop, Cursor and VS Code. If you want it rolled out across a team with permissions, governance and support handled, that is what Crox's Build engagement covers.

Want this connected to your business — with governance handled?
Crox maps your processes, connects AI to the tools you already use, and keeps it working as models change. Start with a readiness assessment or talk to us about a build.
