origin-mcp-stdio

Standard I/O transport adapter for Model Context Protocol (MCP) servers in Origin.

Part of Origin, a Rust/Tauri platform for building desktop applications from a shared set of domain crates. See the workspace documentation for how the pieces fit together, and ARCHITECTURE.md for the rules this crate follows.

Example

use origin_mcp_core::McpServer;
use origin_mcp_stdio::serve;

let server = McpServer::new("my-product", "0.1.0");

// Serve JSON-RPC over stdin/stdout until client disconnects
serve(&server).await?;

Serves headless MCP tool interactions over standard input and output streams when the GUI is not running. To prevent protocol stream corruption, stdout is reserved strictly for protocol messages (logging must be routed to stderr or disabled).

Stability

Pre-1.0 (0.2.0). Public types, enums and field sets may still change between minor versions; pin an exact version if that matters to you.
