# Retrieve a Signal

> Retrieve one signal by its 1eye signal ID.

Use an ID from [Search Signals](https://docs.1eye.ai/mcp/tools/search-signals.md) or a buyer's first/last signal references. Resolve the returned `buyer_id` with [Retrieve a Buyer](https://docs.1eye.ai/mcp/tools/retrieve-a-buyer.md).

The examples below are MCP tool arguments. Replace uppercase IDs with values returned by your workspace.
