envalid_validate

MCP tool from When by WhenLabs-org

Validate .env files against schema

How to use it

Project documentation lists envalid_validate for the When MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
