yap-mcp

Overview ¶

Package main is the entrypoint for the yap-mcp binary — an MCP (Model Context Protocol) server that exposes yap's package-build capabilities to MCP-compatible clients (Claude Desktop, IDE agents, etc.).

v1 binds the stdio transport. HTTP+SSE is planned but gated for later.

Shutdown semantics: the server exits cleanly when any of these happen:

• stdin reaches EOF (the SDK's stdio transport Read returns and Run unblocks)
• SIGINT / SIGTERM is delivered
• parent process dies (Linux PR_SET_PDEATHSIG → SIGTERM)

Logging: stdout is reserved for the JSON-RPC stream. All log output goes to stderr via pkg/logger. Set YAP_VERBOSE=1 for debug-level frames.
