Automated feature flag workflows in Mastra AI

Create complex logic flows using `create_feature` and `update_feature` inside your Mastra agents. If an update fails, the agent handles the retry logic automatically. This setup ensures your flag management remains consistent. You define the steps, and the agent executes the sequence reliably.

Project governance for Mastra AI

Track your organizational hierarchy by using `list_projects` and `update_project` within your agent's workflow. It keeps your feature flags grouped correctly. Senior engineers can use `delete_project` to clean up stale environments. This keeps your GrowthBook instance tidy without manual intervention.

Environment management with Mastra AI

Manage your deployment pipeline by checking `list_environments` before executing changes. It prevents accidental updates to the wrong production slot. Use `create_environment` to spin up new testing zones on the fly. Your agent handles the setup while you focus on the logic.

Setup guide

Set up GrowthBook MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All GrowthBook tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "growthbook-mcp-client",
  servers: {
    "growthbook-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "GrowthBook Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to GrowthBook tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent GrowthBook transactions"
);
console.log(result.text);
