DevPlan MCP Server
Transform ideas into executable development plans — an MCP server that brings the ClaudeCode-DevPlanBuilder methodology to Claude Code.
The Problem: AI coding assistants often lose context, skip steps, or produce inconsistent code across sessions.
The Solution: DevPlan creates detailed, agent-executable development plans with built-in validation, lessons learned, and inline git workflows.
NEW — Install as a Skill (No MCP Server Required)
DevPlan is now available as a standalone Claude Code skill — no MCP server, no network dependency, no SSE timeouts. The entire DevPlan methodology runs locally as a first-class plugin.
