How to Use the CoinMarketCap MCP in Mastra AI

Q: How do I register CoinMarketCap tools in a Mastra AI agent?

Install @mastra/mcp and instantiate the client with your Vinkius endpoint. You then fetch the tools via listTools() and spread them directly into your Mastra agent's tool configuration array.

Q: How do I require approval before Mastra AI queries CoinMarketCap?

Set requireToolApproval to true on your Mastra agent for specific tools like priceconversion. The agent will halt and wait for human confirmation before converting currencies.

Build resilient, auto-retrying crypto workflows by connecting Mastra AI to the CoinMarketCap MCP Server.

Build Auto-Retrying Market Watches

The `get_global_metrics` tool pulls aggregate market data into your Mastra AI workflows to track overall industry health. If the CoinMarketCap API rate limit hits, Mastra's built-in retry engine backs off and tries again without failing the workflow. You can write conditional branches based on global volume shifts. This MCP setup lets you trigger downstream tasks like sending slack alerts or updating databases when market caps cross specific thresholds.

Map Token IDs Safely with Mastra AI Workflows

The `get_id_map` tool resolves messy token symbols into unique CoinMarketCap IDs inside your Mastra AI agents. This step is critical before executing price checks to ensure your workflow doesn't query the wrong token contract. By using this MCP Server tool, your Mastra workflows handle token ambiguities natively. Your agent verifies the exact asset ID first, then passes it to downstream steps safely.

Track Exchange Rankings with Human Approval

The `list_exchanges` tool retrieves ranked cryptocurrency platforms to help your Mastra AI agent evaluate liquidity sources. You can configure Mastra's human-in-the-loop feature to require manual approval before the agent acts on these rankings. This prevents your automated systems from making decisions based on sudden exchange shifts. Your workflow pauses, alerts you, and waits for a thumbs-up before proceeding.

Setup guide

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

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

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