Describe the bug

• After connecting Obsidian MCP in Claude Desktop, when requesting to create a long file using the create-note tool, either there is no response, or even if successful, subsequent Obsidian MCP tool calls hang indefinitely

To Reproduce
Steps to reproduce the behavior:

1. Connect Obsidian MCP in Claude Desktop
2. Request to create a long document in a vault path (e.g., "Please record the conversation from this session as-is to a specific path using Obsidian MCP")
3. Document starts being written with create-note tool, but tool call hangs indefinitely with no response
4. Even if successful, attempting a new tool call causes it to hang

Expected behavior

• Subsequent tool calls should succeed regardless of the length of the generated document

Error logs (if available)
McpError: MCP error -32001: Request timed out error log recorded in ~Library/Logs/Claude/mcp*.log

Desktop (please complete the following information):

• OS: macOS
• AI Client: Claude Desktop

Additional context
After changing validateVaultPath and safeJoinPath to async and adding await at all calling locations, then building and running the MCP server based on the built files, the same issue did not reproduce.
