About Flipt MCP Server

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

LangChain's ecosystem of 500+ components combines seamlessly with Flipt through native MCP adapters. Connect 9 tools via Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures. with LangSmith tracing giving full visibility into every tool call, latency, and token cost.

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 LangChain in under two minutes — credentials fully managed, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

All 9 Flipt tools available for LangChain

When LangChain connects to Flipt through Vinkius, your AI agent gets direct access to every tool listed below — spanning feature-flags, rollouts, targeting, 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.

Flipt + LangChain FAQ

Common questions about integrating Flipt MCP Server with LangChain.

01

How does LangChain connect to MCP servers?

Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
02

Which LangChain agent types work with MCP?

All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
03

Can I trace MCP tool calls in LangSmith?

Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
