SpecLeft

Overview

SpecLeft is a Python intent tracing MCP server that maps specifications to pytest tests and monitors implementation progress. It runs entirely offline, helping you bridge the gap between intent and test coverage without external dependencies or API calls.

The server installs locally via uvx specleft and communicates with your MCP client over stdio. No authentication is required. SpecLeft v0.4.0 is released under the Apache-2.0 license with source code available at SpecLeft/specleft on GitHub.

SpecLeft appears in the AI & Agents category on mcp.site and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you maintain SpecLeft, claim this listing to verify ownership and keep information up to date.
