Perplexity

Automate transaction loops with this MCP Server

The `eth_sendRawTransaction` tool broadcasts signed payloads directly to the Ethereum mempool. If a transaction stalls due to low fees, Mastra AI triggers a workflow to fetch new parameters using `get_suggested_gas_fees`. Our workflow engine automatically retries the broadcast with updated gas pricing. You define the backoff limits in TypeScript, ensuring your agent never leaves transactions stuck in the mempool forever.

Execute read-only contract calls automatically

The `eth_call` tool executes message calls directly against the virtual machine without creating a transaction. Mastra AI uses this to query contract state, verify user balances with `eth_getBalance`, and route decisions based on the output. If a contract check fails, the workflow branches to notify an admin or try an alternative path. This lets you build complex DeFi automation that responds dynamically to on-chain conditions.

Set up persistent event filters in Mastra AI

The `eth_newFilter` tool creates a tracking filter on the node for specific contract topics. Mastra AI's persistent workers poll this filter using `eth_getFilterChanges` to catch events as they occur. When a matching event is found, the agent triggers subsequent tools like `eth_getTransactionReceipt` to pull transaction details. This builds a closed loop from event detection to database logging.

Setup guide

Set up Infura (Ethereum Node RPC Provider) 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 Infura (Ethereum Node RPC Provider) 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: "infura-ethereum-node-rpc-provider-mcp-client",
  servers: {
    "infura-ethereum-node-rpc-provider-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent Infura (Ethereum Node RPC Provider) transactions"
);
console.log(result.text);

Common questions about Infura (Ethereum Node RPC Provider) MCP in Mastra AI

You register the MCP server URL in your Mastra configuration and pass the tools directly to your agent.

Yes, the workflow engine has built-in retry logic with exponential backoff. If `eth_getLogs` hits a rate limit, Mastra pauses and retries automatically.

You can filter the tools during initialization. For example, you might only expose read operations like `eth_blockNumber` while blocking execution tools.

Yes, you can use `eth_feeHistory` and `eth_getBlockByNumber` to build deep historical models of gas prices and block activity.

All transaction payloads and RPC queries pass through the Vinkius V8 sandbox. Your private keys never touch external servers, and the sandbox is destroyed immediately after execution.
