From fa6238a24bce73c3d5716363c2e7a1f740866d1d Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 15 Nov 2025 16:51:21 +0000 Subject: [PATCH 1/3] feat: add support for custom HTTP and HTTPS ports via environment variables (#40) Add OBSIDIAN_HTTP_PORT and OBSIDIAN_HTTPS_PORT environment variables to allow users to configure custom ports for the MCP server. This provides: - Port conflict resolution for environments where default ports are in use - Environmental flexibility for restrictive network configurations - Enhanced security through non-standard port usage The implementation maintains backward compatibility by defaulting to the original ports (27123 for HTTP, 27124 for HTTPS) when environment variables are not set. Updated documentation in packages/mcp-server/README.md to include configuration examples and descriptions of all available environment variables.
