Worked on enhancing the dbt-labs/dbt-mcp repository by improving the robustness of the Dbt CLI tooling through targeted bug fixes. Addressed a TypeError encountered in certain dbt commands by introducing an exclude_tools parameter to the register_dbt_cli_tools function, allowing for selective registration of CLI tools and preventing unintended tool registrations. This update stabilized command execution and simplified future maintenance by making the tool registration process more explicit. The work was implemented using Python and focused on CLI development, with clear commit documentation to support future audits and rollbacks. The changes contributed to more reliable and maintainable CLI tool operations.
