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 Pydantic AI?
Pydantic AI validates every Tenderly (Ethereum Dev Platform) tool response against typed schemas, catching data inconsistencies at build time. Connect 4 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.
- —
Full type safety: every MCP tool response is validated against Pydantic models, catching data inconsistencies before they reach your application
- —
Model-agnostic architecture. switch between OpenAI, Anthropic, or Gemini without changing your Tenderly (Ethereum Dev Platform) integration code
- —
Structured output guarantee: Pydantic AI ensures tool results conform to defined schemas, eliminating runtime type errors
- —
Dependency injection system cleanly separates your Tenderly (Ethereum Dev Platform) connection logic from agent behavior for testable, maintainable code

Why teams choose Vinkius for Tenderly (Ethereum Dev Platform) in Pydantic AI
The Tenderly (Ethereum Dev Platform) MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 4 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in Pydantic AI only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.
* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
Tenderly (Ethereum Dev Platform) for Pydantic AI
Every tool call from Pydantic AI to the Tenderly (Ethereum Dev Platform) MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
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 does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Tenderly (Ethereum Dev Platform) MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
