Tenderly (Ethereum Dev Platform)

What is the Tenderly (Ethereum Dev Platform) MCP Server?

Connect your Tenderly account to any AI agent to streamline your Ethereum development workflow. This MCP server allows you to debug, simulate, and monitor smart contracts through natural language.

What you can do

  • Transaction Simulation — Simulate single transactions or complex bundles on any supported network without committing real assets or spending gas.
  • Virtual TestNets — Create and manage private mainnet replicas (Virtual TestNets) to test your dApps in a production-like environment with custom configurations.
  • On-Chain Monitoring — Set up sophisticated alerts for method calls, state changes, or value transfers to stay informed about blockchain activity in real-time.
  • Bundle Execution — Test sequences of transactions to see how they interact, perfect for debugging complex DeFi protocols or multi-step workflows.

How it works

  1. Subscribe to this server
  2. Provide your Tenderly Access Key, Account Slug, and Project Slug
  3. Start simulating transactions and managing testnets from Claude, Cursor, or any MCP client

Who is this for?

  • Smart Contract Engineers — debug transactions and verify contract behavior before deployment.
  • DeFi Researchers — simulate complex multi-step transactions to analyze protocol interactions.
  • Web3 DevOps — monitor production contracts and manage private testing environments seamlessly.

FAQ

Frequently asked questions

01

Can I simulate a transaction without spending real ETH or gas?

Yes! Use the simulate_transaction tool. It runs the transaction against the latest state of the network in a virtual environment, providing full trace and results without any on-chain cost.

02

How do I create a private fork of Ethereum for testing?

You can use the create_virtual_testnet tool. Provide a slug, display name, and the network ID you want to fork from (e.g., 1 for Mainnet) to spin up a private RPC endpoint.

03

Can I monitor specific smart contract events automatically?

Absolutely. Use the create_alert tool with an alert_config object to monitor method calls, state changes, or emitted logs on any contract address.

04

How does LlamaIndex connect to MCP servers?

Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.

05

Can I combine MCP tools with vector stores?

Yes. LlamaIndex agents can query Tenderly (Ethereum Dev Platform) tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.

06

Does LlamaIndex support async MCP calls?

Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
