How to Use the Precisely MCP in Mastra AI

Q: How do I register Precisely tools inside a Mastra AI agent?

Instantiate the client using new MCPClient and spread the tools from listTools() into your agent configuration. The agent automatically understands how to call tools like geocodeaddress.

Q: Does Mastra AI support human-in-the-loop approvals for Precisely tax queries?

You can enable requireToolApproval for sensitive actions like getlocaltax. The workflow pauses until an admin approves the calculated tax rate before finalizing the transaction.

Build reliable property risk and tax automation workflows using Mastra AI agents and the Precisely MCP Server.

Multi-step risk workflows with Mastra AI

The `enrich_flood_risk` tool integrates directly into Mastra AI workflows to automate property hazard assessments. This MCP setup lets you branch logic dynamically if a property falls into high-risk zones. Using `enrich_crime_risk` alongside this workflow lets you build automated underwriting steps. Mastra's built-in retry engine handles any transient API blips, ensuring your risk assessments never fail silently.

Automated address validation and geocoding pipelines

The `verify_address` tool acts as the primary gatekeeper in your Mastra AI data ingestion pipeline. It standardizes raw strings against global postal databases before other tools in the MCP Server process them. Once verified, `geocode_address` resolves the location to rooftop-level coordinates. Mastra executes these steps sequentially, passing the precise latitude and longitude to subsequent agent tasks.

Localized tax and timezone resolution

The `get_local_tax` tool resolves complex, overlapping tax jurisdictions within your Mastra AI automated billing agent. Your agent pulls exact rates based on parcel boundaries to calculate invoice totals. It then uses `get_timezone` to schedule follow-up emails at the optimal local time. This combination ensures your automated billing flows are both financially accurate and chronologically sensible.

Setup guide

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

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

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

Common questions about Precisely MCP in Mastra AI

Instantiate the client using `new MCPClient` and spread the tools from `listTools()` into your agent configuration. The agent automatically understands how to call tools like `geocode_address`.

Yes, Mastra's workflow engine manages automatic retries with exponential backoff. If `enrich_demographics` hits a rate limit, the workflow pauses and retries without dropping the execution state.

You can enable `requireToolApproval` for sensitive actions like `get_local_tax`. The workflow pauses until an admin approves the calculated tax rate before finalizing the transaction.

The client automatically detects the transport, resolving to either Streamable HTTP or Server-Sent Events. This ensures zero-config connectivity to the Vinkius gateway.

Vinkius executes all tax and demographic queries in isolated, zero-trust sandboxes. No socio-economic profiles or local tax details are cached, protecting your proprietary business logic.
