Tenderly MCP: simulate and debug onchain from your editor

Tenderly's MCP server brings its blockchain development platform into your AI app, so you can simulate, debug and test across more than 100 networks without leaving Cursor or Claude Code. ContextGate connects it to Claude, ChatGPT and Cursor, keeps every simulation and debug request in Activity, and lets you switch off any tool you'd rather not expose.

  4. 4Ask your AI app to simulate a transaction on one of the networks you deploy to, then open Activity to see the call.

Blockchain dev work with Tenderly in the loop

  • Simulate before anything goes onchain, from a chat in Cursor or Claude Code.
  • Debug a problem with Tenderly's tools while your AI app has your code open.
  • Test on any of the 100+ networks Tenderly supports.

Control what Tenderly's tools can reach

  • Switch off any Tenderly tool and it's hidden from your AI app; a call to it is refused.
  • A policy can block private keys or other secrets from going out in a Tenderly call.
  • Activity keeps a record of every simulation and debug request.

What you get with Tenderly and ContextGate

  • Your AI apps can use TenderlyClaude, Cursor, ChatGPT and other AI apps reach Tenderly through the one ContextGate connection you add to them.
  • You choose which tools they can useSwitch off any Tenderly tool you don't want used. It's hidden from your AI apps and refused if called.
  • Every call is checked and recordedYour policies check each call (for example, personal data is hidden and secrets are blocked), and Activity keeps a record of it.

ContextGate sees only the tool calls that go through it, not your AI app's built-in tools or your chats.
