How to Use the Browserbase MCP in Mastra AI

Q: How do I register the Browserbase MCP Server tools in Mastra AI?

Install @mastra/mcp and instantiate the client with your Vinkius URL. Then, initialize the MCP client to fetch the tools using listTools and spread them directly into your Mastra Agent configuration.

Q: Can I inspect active Browserbase sessions from a Mastra workflow?

Yes, use getbrowsersession inside any step to fetch the current status of your browser. You can use this data to decide whether to branch or proceed.

Perplexity

Build Fault-Tolerant Workflows with Mastra AI

Web scraping is notoriously fragile because sites change and network requests drop. Running your automation via this MCP Server lets you wrap `create_browser_session` in a workflow step with built-in retry logic and exponential backoff. If a page fails to load, Mastra automatically retries the step or branches to an alternate path. You don't have to write custom error-handling code to keep your browser sessions alive.

Inject Human Approval Into Live Browser Sessions

Giving an agent full control over a browser can be risky, especially when dealing with checkouts or sensitive settings. Mastra's tool approval feature pauses execution before calling `stop_browser_session` or executing actions. A developer or admin can review the current session state via `get_browser_session` before giving the green light. This keeps your automated processes safe and compliant without losing momentum.

Track Complex Parallel Sessions via Mastra Engine

Running multiple scraping tasks in parallel requires solid state tracking. The `list_browser_sessions` tool gives your Mastra agents a clear view of every active task. The framework maps these session IDs to its internal state machine. You can easily coordinate parallel browser tasks and aggregate the results once they transition to completed.

Setup guide

Set up Browserbase 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 Browserbase 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: "browserbase-mcp-client",
  servers: {
    "browserbase-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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

Common questions about Browserbase MCP in Mastra AI

Install `@mastra/mcp` and instantiate the client with your Vinkius URL. Then, initialize the MCP client to fetch the tools using `listTools` and spread them directly into your Mastra Agent configuration.

Yes, you can configure Mastra workflows to catch errors from `create_browser_session`. The engine will automatically retry the step using backoff strategies you define.

Sessions automatically time out after 300 seconds, but you should call `stop_browser_session` in your workflow's cleanup block. This ensures you do not waste resources on completed tasks.

Yes, use `get_browser_session` inside any step to fetch the current status of your browser. You can use this data to decide whether to branch or proceed.

Your credentials, session cookies, and local storage data remain strictly inside the isolated cloud browser environment controlled by the MCP protocol. This temporary data is completely destroyed as soon as the session is terminated.
