How to Use the Climatiq Carbon Calculations MCP in Mastra AI

Q: Can I require human approval before running a Climatiq Carbon Calculations step in Mastra AI?

Yes. You can set requireToolApproval on the Mastra agent to pause the workflow before it calls the estimateemissions tool.

Q: How do I register the Climatiq Carbon Calculations MCP Server in my Mastra AI project?

Install @mastra/mcp and initialize the MCP client using the Vinkius HTTP endpoint. You then spread the tools directly into your Mastra Agent configuration.

Q: How do I ensure my automated workflows use the latest emission factors?

Your agent can query listyears and listsources at the start of the workflow. This ensures the calculations use the most recent data points available in the database.

Perplexity

Automated industry-code carbon mapping

The `estimate_by_classification` tool maps carbon emissions using standard industry codes like ISIC or NACE directly inside your Mastra AI workflows. It lets your agents categorize corporate activities and calculate footprint data without manual translation. If an API call fails during a multi-step workflow, Mastra's engine automatically retries the calculation with exponential backoff. This ensures your automated sustainability audits run to completion even during network hiccups.

Dynamic carbon factor search and fallback

The `search_emission_factors` tool queries the Climatiq database for specific carbon coefficients within your Mastra AI agent steps. Your agent uses these search results to find the most accurate factor before executing a calculation. You can set up conditional branching to handle missing data. If the search returns empty, the Mastra workflow branches to alternative classification lookups or asks a human supervisor for approval before proceeding.

Multi-region carbon auditing

The `list_regions` tool retrieves supported regions to validate geographical inputs before your Mastra AI agent triggers a carbon calculation. It prevents runtime errors by ensuring the target region exists in the Climatiq database. By integrating this MCP Server with Mastra's workflow steps, you build resilient compliance pipelines. The agent checks available years first, then branches to the correct calculation tool based on the available data.

Setup guide

Set up Climatiq Carbon Calculations 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 Climatiq Carbon Calculations 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: "climatiq-carbon-calculations-mcp-client",
  servers: {
    "climatiq-carbon-calculations-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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

Common questions about Climatiq Carbon Calculations MCP in Mastra AI

Mastra AI features a built-in workflow engine that handles retries. If the Climatiq Carbon Calculations tools timeout, the engine automatically retries the step with exponential backoff.

Yes. You can set `requireToolApproval` on the Mastra agent to pause the workflow before it calls the `estimate_emissions` tool.

Install `@mastra/mcp` and initialize the MCP client using the Vinkius HTTP endpoint. You then spread the tools directly into your Mastra Agent configuration.

Your agent can query `list_years` and `list_sources` at the start of the workflow. This ensures the calculations use the most recent data points available in the database.

All industrial activity data and carbon calculations are processed inside an ephemeral, zero-trust sandbox. No data is stored on disk, and Vinkius handles the Climatiq API keys securely outside your codebase.
