About Flipt MCP Server

Connect your Flipt instance to any AI agent to orchestrate feature management and progressive delivery through natural conversation.

Pydantic AI validates every Flipt tool response against typed schemas, catching data inconsistencies at build time. Connect 9 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

Flag Management — List and inspect feature flags across different namespaces to understand your current feature states
Targeting & Segments — Retrieve segments and create constraints to define specific user subsets for targeted rollouts
Rollout Control — List rules and rollouts, and create distributions to manage percentage-based releases and canary deployments
Variants — Create and manage flag variants to return different values based on evaluation logic
Auth & Infrastructure — List authentication tokens and namespaces to understand your environment's structure and access levels

The Flipt MCP Server exposes 9 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.

Why Use Pydantic AI with the Flipt MCP Server

Pydantic AI provides unique advantages when paired with Flipt 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 Flipt integration code

Structured output guarantee: Pydantic AI ensures tool results conform to defined schemas, eliminating runtime type errors

Dependency injection system cleanly separates your Flipt connection logic from agent behavior for testable, maintainable code

Flipt + Pydantic AI Use Cases

Practical scenarios where Pydantic AI combined with the Flipt MCP Server delivers measurable value.

Type-safe data pipelines: query Flipt with guaranteed response schemas, feeding validated data into downstream processing

API orchestration: chain multiple Flipt tool calls with Pydantic validation at each step to ensure data integrity end-to-end

Production monitoring: build validated alert agents that query Flipt and output structured, schema-compliant notifications

Testing and QA: use Pydantic AI's dependency injection to mock Flipt responses and write comprehensive agent tests

Example Prompts for Flipt in Pydantic AI

Ready-to-use prompts you can give your Pydantic AI agent to start working with Flipt immediately.

"List all namespaces in my Flipt instance."

"Show me all the feature flags in the 'default' namespace."

"Create a new variant called 'v2-test' for the 'header-experiment' flag in the 'default' namespace."

Flipt + Pydantic AI FAQ

Common questions about integrating Flipt MCP Server with Pydantic AI.

How does Pydantic AI discover MCP tools?

Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.

Does Pydantic AI validate MCP tool responses?

Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer. your Flipt MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
