About Statsig MCP Server
Connect your Statsig project to any AI agent to manage feature rollouts and product experiments through natural conversation.
Pydantic AI validates every Statsig tool response against typed schemas, catching data inconsistencies at build time. Connect 12 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
- Feature Gates — Evaluate if a feature is enabled for a specific user or list all project gates
- Dynamic Configs — Fetch JSON configurations and experiments to control app behavior without code changes
- Event Logging — Log custom events for real-time analytics and metric calculation
- Gate Management — Create, update, or delete feature gates directly via the Console API
- Layer Inspection — Evaluate layers and retrieve parameter values for specific users
The Statsig MCP Server exposes 12 tools through the Vinkius. Connect it to Pydantic AI in under two minutes — credentials fully managed, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
All 12 Statsig tools available for Pydantic AI
When Pydantic AI connects to Statsig through Vinkius, your AI agent gets direct access to every tool listed below — spanning feature-flags, ab-testing, product-experimentation, and more. Every call runs in a secure, isolated environment with full audit visibility. Beyond a simple connection, you get real-time monitoring of agent activity, enterprise governance, and optimized token usage.

Why Use Pydantic AI with the Statsig MCP Server
Pydantic AI provides unique advantages when paired with Statsig 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 Statsig integration code
Structured output guarantee: Pydantic AI ensures tool results conform to defined schemas, eliminating runtime type errors
Dependency injection system cleanly separates your Statsig connection logic from agent behavior for testable, maintainable code
Statsig + Pydantic AI Use Cases
Practical scenarios where Pydantic AI combined with the Statsig MCP Server delivers measurable value.
Type-safe data pipelines: query Statsig with guaranteed response schemas, feeding validated data into downstream processing
API orchestration: chain multiple Statsig tool calls with Pydantic validation at each step to ensure data integrity end-to-end
Production monitoring: build validated alert agents that query Statsig and output structured, schema-compliant notifications
Testing and QA: use Pydantic AI's dependency injection to mock Statsig responses and write comprehensive agent tests
Example Prompts for Statsig in Pydantic AI
Ready-to-use prompts you can give your Pydantic AI agent to start working with Statsig immediately.
"Check if the gate 'new_checkout_flow' is enabled for user 'user_99'."
"List all feature gates in my Statsig project."
"Create a new feature gate named 'mobile_redesign' with description 'Testing new UI'."
