How to Use the Nutshell CRM MCP in Mastra AI

Q: How do I register the Nutshell CRM MCP Server with a Mastra AI agent?

Instantiate the client using new MCPClient with your Vinkius URL. Then, call mcpClient.listTools() and spread the resulting toolset directly into your agent's tool array.

Q: Can I require human approval before Mastra AI modifies Nutshell CRM data?

Yes, you can use the requireToolApproval config option. This pauses the workflow whenever the agent attempts to run tools that pull sensitive data like getleaddetails.

Perplexity

Resilient lead enrichment pipelines

The `list_custom_fields` tool identifies the exact data structure of your Nutshell CRM setup. Your agent uses this tool to map external incoming webhooks to your specific CRM fields before creating or updating records. By using Mastra AI, you can build a workflow that automatically retries if the CRM API rate limit is temporarily reached. The built-in exponential backoff ensures your lead enrichment never drops a record due to transient network errors.

Audit team activities with Mastra AI workflows

The `list_activities` tool retrieves logged calls, emails, and meetings to track sales rep engagement. It exposes dates, assignees, and notes so your agent can analyze team performance. You can write a Mastra AI workflow that checks activity volume and branches conditionally based on the results. If a high-value account has zero logged tasks, the agent can trigger an alert, requiring human approval before sending a follow-up email.

Deep account lookups with this MCP Server

The `get_account_details` tool extracts deep business information for any organization in your database. It reveals parent accounts, industry classifications, and associated contacts. Mastra AI handles these multi-step lookups by passing the output of `list_accounts` directly into the detail tool. You get a clean, structured JSON payload that your agent can analyze or sync to external databases.

Setup guide

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

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

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

The framework automatically detects transport issues over HTTP or SSE. It uses standard retry logic to reconnect to the MCP Server without crashing your active workflow.

It uses Streamable HTTP or Server-Sent Events (SSE) depending on your hosting setup. Mastra AI auto-detects the transport type when you initialize the client with the server URL.

Your leads, contacts, accounts, and activities never touch third-party storage. All tool executions occur inside a zero-trust, ephemeral sandbox that destroys the runtime container immediately after the agent finishes its task.
