project_eval

MCP tool from Tidewave Rails by tidewave-ai

Evaluates Ruby code in the context of your running application, with access to its runtime, loaded dependencies, and in-memory data, returning the result plus anything printed to standard output. It's like a Rails console for the agent.

How to use it

project_eval is exposed by the Tidewave Rails MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), and the project_eval tool becomes available to the model automatically. See the full listing for setup details and every tool this server provides.
