parse
Parse and validate dbt project contents for Jinja or YAML syntax errors, generating a detailed artifact with timing insights for large project analysis.
Instructions
The dbt parse command parses and validates the contents of your dbt project. If your project contains Jinja or YAML syntax errors, the command will fail.
It will also produce an artifact with detailed timing information, which is useful to understand parsing times for large projects.

Implementation Reference
- src/dbt_mcp/dbt_cli/tools.py:126-128 (handler)Handler function for the 'parse' MCP tool. Executes the dbt parse command using the shared _run_dbt_command helper.def parse() -> str: return _run_dbt_command(["parse"])
- src/dbt_mcp/dbt_cli/tools.py:222-231 (registration)Registration of the 'parse' tool via ToolDefinition, specifying the handler function, description from prompts, and annotations for tool behavior.ToolDefinition( fn=parse, description=get_prompt("dbt_cli/parse"), annotations=create_tool_annotations( title="dbt parse", read_only_hint=True, destructive_hint=False, idempotent_hint=True, ), ),
