Extend your helper thoughtfully
Understand tool plugins and imported workflow bundles before installing them.
Your space → Connections → Tools & MCP / Skills
Before you begin
A compatible Mellow build with the relevant capability configured.
Read what it adds
Inspect the package description, permissions and resources. A skills-only package and executable tool plugin have different capabilities.
Configure the prerequisites
Supply only the credentials and connections it needs. Check any imported schedules before enabling them.
Test in a bounded task
Exercise one capability and review its output and activity. Do not assume installing a package establishes every included connection.
Controls & reference
| Control or concept | How to use it |
|---|---|
| Native tool plugin | Executable extension subject to the app’s loading and signing requirements. |
| Workflow bundle | May contain skills, commands, schedules and MCP connection definitions. |
| Configure Secrets | Use dedicated credential controls for keys the extension needs. |
| Uninstall | Review the resources created by the bundle before removing it. |
Try it with a small task
Import a simple text-only workflow, inspect its instructions, and run it on a short non-sensitive paragraph.
If it does not work
- Hosted plugin catalogs may be unavailable in a particular deployment.
- A failed plugin should be investigated through its error and activity logs, not by weakening signing requirements.
