What is the Flipt MCP Server?
Connect your Flipt instance to any AI agent to orchestrate feature management and progressive delivery through natural conversation.
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
How it works
- Subscribe to this server
- Enter your Flipt URL and API Token
- Start managing your feature flags from Claude, Cursor, or any MCP-compatible client
Who is this for?
- DevOps Engineers — quickly audit rollout configurations and namespace partitions without leaving the terminal or IDE
- Product Managers — check the status of feature flags and segments to verify release progress
- Developers — create variants and constraints directly while coding to speed up feature implementation

Why teams choose Vinkius for Flipt in Vercel AI SDK
The Flipt MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 9 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in Vercel AI SDK only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.
* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
Flipt for Vercel AI SDK
Every tool call from Vercel AI SDK to the Flipt MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I list all feature flags in a specific namespace?
Yes! Use the list_flags tool and provide the namespaceKey (e.g., 'default'). The agent will return all flags configured within that partition.
How do I define a new variant for an existing flag?
You can use the create_variant action. You'll need to specify the namespaceKey, flagKey, and the new variant's key and name.
Is it possible to see the rollout configuration for a specific flag?
Absolutely. Use the list_rollouts tool by providing the target namespaceKey and flagKey to retrieve the current rollout strategy.
How does the Vercel AI SDK connect to MCP servers?
Import createMCPClient from @ai-sdk/mcp and pass the server URL. The SDK discovers all tools and provides typed TypeScript interfaces for each one.
Can I use MCP tools in Edge Functions?
Yes. The AI SDK is fully edge-compatible. MCP connections work on Vercel Edge Functions, Cloudflare Workers, and similar runtimes.
Does it support streaming tool results?
Yes. The SDK provides streaming primitives like useChat and streamText that handle tool calls and display results progressively in the UI.
createMCPClient is not a function
Install: npm install @ai-sdk/mcp
