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.

01

Read what it adds

Inspect the package description, permissions and resources. A skills-only package and executable tool plugin have different capabilities.

02

Configure the prerequisites

Supply only the credentials and connections it needs. Check any imported schedules before enabling them.

03

Test in a bounded task

Exercise one capability and review its output and activity. Do not assume installing a package establishes every included connection.

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.
