# discover\_plugins

<div className="flex items-center gap-2">
  <Badge color="purple">Method</Badge>
</div>

> This is a method of the [**ToolRegistry**](../classes/ToolRegistry) class in the [**registry**](../modules/registry) module.

Discover and register tools from entry\_points.

External packages publish a tool by registering it under the canonical
`praisonai.tools` entry-point group in pyproject.toml::

\[project.entry-points."praisonai.tools"]
my\_tool = "my\_package.tools:MyTool"

The historical `praisonaiagents.tools` and `praisonai.tool_sources`
groups are still discovered as deprecated aliases (a one-time
`DeprecationWarning` is emitted on first hit). The canonical group wins
on a name collision, so a name is never overwritten by an alias group.
