Mcp Simulate

Overview

Mcp Simulate is a Model Context Protocol (MCP) server: MCP server for dry-run Ethereum transaction simulation via Crypto APIs. In practice that means any MCP-compatible AI assistant can call Mcp Simulate's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the npm package @cryptoapis-io/mcp-simulate speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need CRYPTOAPIS_API_KEY. The current release is v0.3.1, with source at CryptoAPIs-io/cryptoapis-mcp-simulate on GitHub.

Mcp Simulate is listed under Finance on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
