From 034e718a78f49000606c4d0bd79adae1041f14db Mon Sep 17 00:00:00 2001 From: Ryan Parmeter Date: Mon, 10 Nov 2025 18:10:06 -0700 Subject: [PATCH] fix: Simplify binary resolution - return Homebrew path directly on macOS MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Problem Binary path discovery was still failing on macOS because: 1. PathBuf::exists() returns false in WASM sandbox for all paths 2. Even though we check all paths first, they all fail exists() check 3. We then hit the fallback logic and return the first absolute path ## Solution Since WASM sandbox restricts filesystem checks anyway, take a pragmatic approach: - On macOS: Return /opt/homebrew/bin/gitea-mcp-server directly (Homebrew is the recommended method) - On Linux/Windows: Try to check exists() on standard paths, then PATH, then fallback This works because: - Homebrew is the recommended/preferred installation method for macOS - Most macOS users installing via Homebrew will use that path - Users can still override with gitea_mcp_binary_path if needed - On Linux, exists() checks should work fine without WASM sandbox restrictions ## Testing - ✅ Builds without errors - 🔄 Ready for testing on macOS M4 with Homebrew --- src/mcp_server_gitea.rs | 142 +++++++++++++--------------------------- 1 file changed, 47 insertions(+), 95 deletions(-) diff --git a/src/mcp_server_gitea.rs b/src/mcp_server_gitea.rs index e343997..7905d6d 100644 --- a/src/mcp_server_gitea.rs +++ b/src/mcp_server_gitea.rs @@ -250,128 +250,80 @@ fn find_docker_binary() -> Result { /// Resolve the gitea-mcp binary path with intelligent fallbacks /// /// Resolution strategy: -/// 1.
