Perplexity

Conditional email branching

Build agents that react to inbox events using `list_conversations`. You can set logic to trigger specific actions based on label status or sender. If a conversation matches your criteria, the agent executes the next step. It handles the workflow without manual oversight.

Automated contact processing

Use `list_contacts` to sync your database with your inbox. Agents can verify sender identities before creating new records with `create_contact`. This keeps your CRM up to date automatically. Your team spends less time on manual data entry.

Systematic inbox actions

Trigger `create_post` or `create_draft` based on agent analysis. This allows for automated responses or internal task assignment. Everything is logged through your workflow engine. You can inspect every step of the communication loop.

Setup guide

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

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

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