Type-safe marketing audits with Pydantic AI

Loose, unstructured marketing advice is useless for automated workflows. This MCP Server integrates with your type-safe agent pipelines, ensuring that every strategic critique returned by the `validate_cmo_marketing` tool matches your exact system models. If the validation tool detects a weak positioning statement or an unrealistic payback period, it fails loudly at runtime. This prevents your system from quietly passing flawed marketing campaigns down the pipeline.

Enforce mathematical CAC physics at the code level

Do not trust agents to estimate your customer acquisition costs without strict guardrails. This tool forces your Pydantic AI agent to calculate CAC by channel and define a clear diminishing return threshold before suggesting ad spend increases. By calling `validate_cmo_marketing` within a structured type-safe loop, your agent is forced to verify that your customer lifetime value justifies the payback window. If the math does not close, the run halts.

Inject intentional funnel friction into your schemas

Frictionless signups are a trap that fills your pipeline with junk leads. This tool evaluates your lead-generation configurations to ensure you have built-in barriers like work-email validation or budget qualification fields. Your Pydantic AI agent uses `validate_cmo_marketing` to analyze your web form schemas. It rejects plans that prioritize vanity lead volume over actual sales-ready pipeline quality.
