Best for	Local assistants that need to work inside explicitly approved directories Individuals and development teams that want path-based data boundaries	Analysts and developers exploring PostgreSQL data through natural language Teams exposing schema and query access through a dedicated read-only account	Development teams that want to handle issues, files, and pull requests from a coding assistant Maintainers automating repetitive GitHub workflows
Not for	Highly sensitive environments that cannot allow model access to local file contents Shared remote file-service use cases	Workflows that require writes, migrations, or database administration Sensitive databases whose query results cannot enter a third-party model context	Environments that cannot provide a GitHub token Organizations requiring every repository write to be confirmed manually in GitHub's UI
Required permissions	Read access to every local directory listed in the configuration Filesystem write access when write or move tools are enabled	Network access to PostgreSQL A dedicated read-only account with SELECT access to the intended schemas	A GitHub Personal Access Token Least-privilege Contents, Issues, or Pull requests access for the target repositories
Risks and side effects	Sensitive files inside an allowed directory may enter model context Write and move tools change real files; keep scopes narrow and maintain backups	Query results may contain personal or business-sensitive data Complex read queries can still consume significant resources; use timeouts and a read replica	A leaked high-privilege token can modify repository code and issues The model can create incorrect branches, issues, or pull requests; retain human confirmation for writes
