# `GEPA.Adapters.MCP.Client.Stdio`
[🔗](https://github.com/nshkrdotcom/gepa_ex/blob/v0.3.0/lib/gepa/adapters/mcp/client.ex#L130)

Placeholder stdio MCP transport config.

  Supply a concrete module implementing `GEPA.Adapters.MCP.Client` when you want
  to run a real MCP process.  This struct is intentionally dependency-free so
  the core library does not force an MCP SDK install.
