Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The dbt MCP Server (PyPI package dbt-mcp) before 1.17.1 passes user-supplied tool parameters into dbt CLI argument lists without validation. An MCP client able to call the affected tools (such as build, run, test, or list) can inject dbt global flags like --profiles-dir, --project-dir, and --target through the node_selection or resource_type parameters. Upgrade to dbt-mcp 1.17.1 or later. The source gives no workaround beyond upgrading.
