How to Use the Mailshake MCP in Mastra AI

Q: Can Mastra AI automatically pause Mailshake campaigns if engagement drops?

Yes. You can build a workflow that periodically polls listengagementactivity and uses conditional logic to trigger pausecampaign if open or click rates fall below your target threshold.

Q: Where are my Mailshake campaign metrics stored during Mastra AI executions?

Metrics retrieved via getcampaigndetails are processed in memory and never stored permanently on our MCP Server databases. All traffic is encrypted in transit using TLS 1.3, keeping your sales data secure.

Build resilient outreach workflows in Mastra AI

Stop relying on fragile cron jobs to manage your sales pipeline. This MCP Server exposes tools like `list_sales_leads` directly to your Mastra AI workflows, allowing you to build automated routing rules that trigger whenever a prospect shows high intent. If an API call to `update_lead_status` fails due to a network hiccup, Mastra's built-in retry engine handles exponential backoffs automatically. This ensures your lead records remain perfectly synchronized between Mailshake and your internal databases without manual intervention.

Conditional branching based on campaign engagement

You can design multi-step Mastra workflows that check campaign performance using `list_engagement_activity` and branch based on the results. If a campaign's open rate drops, your Mastra agent can automatically trigger `pause_campaign` to protect your domain reputation. The workflow can then run diagnostics using `get_campaign_details` to analyze the sequence structure before alerting your team. This level of autonomous monitoring keeps your cold email infrastructure safe from deliverability disasters.

Human-in-the-loop validation for prospect uploads

Guard your list quality by requiring approval before adding new leads to active sequences. By setting `requireToolApproval` in your Mastra MCP configuration, you can pause the workflow whenever the agent attempts to run `add_prospects`. A human operator can review the list of names and email addresses before the workflow pushes them to Mailshake. Once approved, the agent resumes and uses `resume_campaign` to keep your outreach moving forward.

Setup guide

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

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

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

Common questions about Mailshake MCP in Mastra AI

Instantiate the MCP client with your Vinkius server URL, retrieve the tools with `listTools()`, and spread them into your Mastra Agent's tool array. The client automatically manages the underlying transport protocols.

Yes. You can build a workflow that periodically polls `list_engagement_activity` and uses conditional logic to trigger `pause_campaign` if open or click rates fall below your target threshold.

Mastra's workflow engine features automatic retries with exponential backoff. If tool calls like `get_team_details` hit rate limits, the system queues the requests and retries them safely.

Yes. You can use Mastra's human-in-the-loop feature to intercept the `add_prospects` tool call, allowing your team to verify lead data before it gets pushed into your active campaigns.

Metrics retrieved via `get_campaign_details` are processed in memory and never stored permanently on our MCP Server databases. All traffic is encrypted in transit using TLS 1.3, keeping your sales data secure.
