MCP server for dry-run EVM transaction simulation via Crypto APIs
Most developer tooling work still happens through a UI a human drives. Cryptoapis MCP Simulate MCP server moves it into the conversation instead. MCP server for dry-run EVM transaction simulation via Crypto APIs.
MCP server for Crypto APIs Simulate product. Dry-run EVM transactions to preview results without broadcasting.
The server publishes 2 tools. What each one is for:
Cursor — The Cursor tool exposed by this serversimulate_evm — The simulate_evm tool exposed by this serverInstallation goes through your MCP client rather than a global install: point it at @cryptoapis-io/mcp-simulate on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Configuration is passed through the environment: CRYPTOAPIS_API_KEY, YOUR_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Cryptoapis MCP Simulate's toolset — Cursor, simulate_evm — is a fair guide to whether it matches your workflow. It is maintained by cryptoapis-io; worth a glance at recent repository activity before you build anything load-bearing on it.
