About Cometly MCP Server
Connect your AI to Cometly, the ad attribution platform for Meta, Google, TikTok and more.
Pydantic AI validates every Cometly tool response against typed schemas, catching data inconsistencies at build time. Connect 8 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.
What you can do
- Event Tracking — Track purchases, leads, and custom events with attribution metadata.
- Campaign Analytics — List campaigns and retrieve ROAS, CPA, and conversion stats.
- Attribution Data — Query which ads drive your highest-value conversions.
The Cometly MCP Server exposes 8 tools through the Vinkius. Connect it to Pydantic AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Why Use Pydantic AI with the Cometly MCP Server
Pydantic AI provides unique advantages when paired with Cometly through the Model Context Protocol.
Full type safety: every MCP tool response is validated against Pydantic models, catching data inconsistencies before they reach your application
Model-agnostic architecture. switch between OpenAI, Anthropic, or Gemini without changing your Cometly integration code
Structured output guarantee: Pydantic AI ensures tool results conform to defined schemas, eliminating runtime type errors
Dependency injection system cleanly separates your Cometly connection logic from agent behavior for testable, maintainable code
Cometly + Pydantic AI Use Cases
Practical scenarios where Pydantic AI combined with the Cometly MCP Server delivers measurable value.
Type-safe data pipelines: query Cometly with guaranteed response schemas, feeding validated data into downstream processing
API orchestration: chain multiple Cometly tool calls with Pydantic validation at each step to ensure data integrity end-to-end
Production monitoring: build validated alert agents that query Cometly and output structured, schema-compliant notifications
Testing and QA: use Pydantic AI's dependency injection to mock Cometly responses and write comprehensive agent tests
