# List Lead sources

`source_channels.list`

List a workspace's active Lead sources (Source Channels) by name or type. Each result identifies how businesses or Deals originate and includes an authorized link to the channel. Read one channel before changing its setup.

[Lead sources guide](https://docs.levr.ai/mcp/resources/source_channels.md)

Availability depends on live discovery and your access to the record. Do not infer MCP calls from REST paths.

Operation: read. Required OAuth scopes: mcp.
