/**
* Generate a file not found error message with troubleshooting tips
*/
static fileNotFound(path: string, operation?: string): string {
const parentPath = PathUtils.getParentPath(path);
const listCommand = parentPath ? `list_notes("${parentPath}")` : 'list_notes()';
return `File not found: "${path}"
The file does not exist in the vault.
Troubleshooting tips:
• Paths are vault-relative (omit leading/trailing slashes)
• Paths are case-sensitive on macOS/Linux
• Use ${listCommand} to see available files in this location
• Verify the file has the correct extension (e.g., .md for markdown)
• Check for typos in the file path
Example: "folder/note.md" instead of "/folder/note.md"`;
}
/**
* Generate a folder not found error message with troubleshooting tips
*/
static folderNotFound(path: string): string {
const parentPath = PathUtils.getParentPath(path);
const listCommand = parentPath ? `list_notes("${parentPath}")` : 'list_notes()';
return `Folder not found: "${path}"
The folder does not exist in the vault.
Troubleshooting tips:
• Paths are vault-relative (omit leading/trailing slashes)
• Paths are case-sensitive on macOS/Linux
• Use ${listCommand} to see available folders in this location
• Verify the folder path is correct
• Check for typos in the folder path
Example: "folder/subfolder" instead of "/folder/subfolder/"`;

* Generate an invalid path error message with troubleshooting tips
*/
static invalidPath(path: string, reason?: string): string {
const reasonText = reason ? `\nReason: ${reason}` : '';
return `Invalid path: "${path}"${reasonText}
Troubleshooting tips:
• Paths must be relative to the vault root
• Do not use leading slashes (/) or backslashes (\\)
• Do not use absolute paths (e.g., C:/ or /home/user/)
• Avoid parent directory traversal (..)
• Avoid invalid characters: < > : " | ? * and control characters
• Use forward slashes (/) as path separators
Valid examples:
• "note.md"
• "folder/note.md"
• "folder/subfolder/note.md"`;
}
/**
* Generate a path already exists error message
*/
static pathAlreadyExists(path: string, type: 'file' | 'folder'): string {
return `${type === 'file' ? 'File' : 'Folder'} already exists: "${path}"
Troubleshooting tips:
• Choose a different name for your ${type}
• Use the update_note tool to modify existing files
• Use the delete_note tool to remove the existing ${type} first
• Check if you intended to update rather than create`;
}
/**
* Generate a parent folder not found error message
*/
static parentFolderNotFound(path: string, parentPath: string): string {
return `Parent folder does not exist: "${parentPath}"
Cannot create "${path}" because its parent folder is missing.
Troubleshooting tips:
• Create the parent folder first using Obsidian
• Verify the folder path with list_notes("${PathUtils.getParentPath(parentPath) || '/'}")
• Check that the parent folder path is correct (vault-relative, case-sensitive on macOS/Linux)
• Note: Automatic parent folder creation is not currently enabled
• Ensure all parent folders in the path exist before creating the file`;
}
/**
* Generate a generic operation failed error message
*/
static operationFailed(operation: string, path: string, error: string): string {
return `Failed to ${operation}: "${path}"
Error: ${error}
Troubleshooting tips:
• Check that the path is valid and accessible
• Verify you have the necessary permissions
• Ensure the vault is not in a read-only state
• Try restarting the MCP server if the issue persists`;
}
/**
* Generate a not a file error message
*/
static notAFile(path: string): string {
return `Path is not a file: "${path}"
The specified path exists but is a folder, not a file.
Troubleshooting tips:
• Use the list_notes() tool with this folder path to see its contents
• Specify a file path within this folder instead
• Check that you're using the correct path`;
}
/**
* Generate a not a folder error message
*/
static notAFolder(path: string): string {
return `Path is not a folder: "${path}"
The specified path exists but is a file, not a folder.
Troubleshooting tips:
• Use read_note() to read this file
• Use list_notes() on the parent folder to see contents
• Specify the parent folder path instead
• Check that you're using the correct path`;
}
/**
* Generate an error for attempting to delete a folder
*/
static cannotDeleteFolder(path: string): string {
return `Path is a folder, not a file: "${path}"
Cannot delete folders using delete_note().
Troubleshooting tips:
• Use list_notes("${path}") to see the folder contents
• Delete individual files within the folder using delete_note()
• Note: Folder deletion API is not currently available
• Ensure you're targeting a file, not a folder`;
}
/**
* Generate an empty path error message
*/
static emptyPath(): string {
return `Path cannot be empty
Troubleshooting tips:
• Provide a valid vault-relative path
• Example: "folder/note.md"
• Use the list_notes() tool to see available files`;
}
/**
* Generate a permission denied error message
*/
static permissionDenied(operation: string, path: string): string {
return `Permission denied: cannot ${operation} "${path}"
Troubleshooting tips:
• Check file/folder permissions on your system
• Ensure the vault is not in a read-only location
• Verify the file is not locked by another application
• Try closing the file in Obsidian if it's currently open`;
}
/**
* Generate a helpful error message for any error
*/
static formatError(error: Error | string, context?: string): string {
const message = error instanceof Error ? error.message : error;
const contextText = context ? `\nContext: ${context}` : '';
return `Error: ${message}${contextText}
If this error persists, please check:
• The MCP server logs for more details
• That your Obsidian vault is accessible
• That the MCP server has proper permissions`;
