From d2a682a4600dcbdcdf6fb6911c90fa856e6cda7f Mon Sep 17 00:00:00 2001 From: Michal Date: Sat, 21 Feb 2026 04:22:01 +0000 Subject: [PATCH] feat: implement mcpd core server framework with Fastify Add Fastify server with config validation (Zod), health/healthz endpoints, auth middleware (Bearer token + session lookup), security plugins (CORS, Helmet, rate limiting), error handler, audit logging, and graceful shutdown. 36 tests passing.
