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 VS Code Copilot?
GitHub Copilot Agent mode brings Tenderly (Ethereum Dev Platform) data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 4 tools. Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.
- —
VS Code is used by over 70% of developers. adding MCP tools to Copilot means your team can leverage external data without leaving their primary editor
- —
Project-scoped MCP configs (
.vscode/mcp.json) let you commit server configurations to your repository, ensuring the entire team shares the same tool access - —
Copilot's Agent mode integrates MCP tools seamlessly with file editing, terminal commands, and workspace search in a single agentic loop
- —
GitHub's enterprise compliance and audit features extend to MCP tool usage, providing visibility into how AI interacts with external services

Why teams choose Vinkius for Tenderly (Ethereum Dev Platform) in VS Code Copilot
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 VS Code Copilot 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 VS Code Copilot
Every tool call from VS Code Copilot 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.
Which VS Code version supports MCP?
MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.
How do I switch to Agent mode?
Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.
Can I restrict which MCP tools Copilot can access?
Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.
Does MCP work in VS Code Remote or Codespaces?
Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
MCP tools not available
Ensure you are in Agent mode in Copilot Chat. MCP tools only appear in Agent mode.
