Before you install Heroku MCP Server

What it can access

An MCP server is a program your AI app starts and talks to. A local one runs with your user's permissions: it can see the files, environment variables and network your account can.

Before you install

Pin the version you reviewed instead of always installing the latest release.
Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.

Maintained by heroku on GitHub, 82 stars and 30 forks. Popularity is not proof of safety.
