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
- Subscribe to this server
- Provide your Tenderly Access Key, Account Slug, and Project Slug
- 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.

Why Claude Code?
Claude Code registers Tenderly (Ethereum Dev Platform) as an MCP server in a single terminal command. Once connected, Claude Code discovers all 4 tools at runtime and can call them headlessly. ideal for CI/CD pipelines, cron jobs, and automated workflows where Tenderly (Ethereum Dev Platform) data drives decisions without human intervention.
- —
Single-command setup:
claude mcp addregisters the server instantly. no config files to edit or applications to restart - —
Terminal-native workflow means MCP tools integrate seamlessly into shell scripts, CI/CD pipelines, and automated DevOps tasks
- —
Claude Code runs headlessly, enabling unattended batch processing using Tenderly (Ethereum Dev Platform) tools in cron jobs or deployment scripts
- —
Built by the same team that created the MCP protocol, ensuring first-class compatibility and the fastest adoption of new protocol features

Frequently asked questions
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.
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.
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.
How do I add an MCP server to Claude Code?
Run claude mcp add <name> --transport http "<url>" in your terminal. Claude Code registers the server and discovers all tools immediately.
Can Claude Code run MCP tools in headless mode?
Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.
How do I list all connected MCP servers?
Run claude mcp in your terminal to see all registered servers and their status, or type /mcp inside an active Claude Code session.
