DevPlan

DevPlan MCP Server provides a dedicated server to guide Claude Code through planning, executing, verifying, and learning from development plans. It attaches an inline methodology to your projects, enabling Haiku-executable plans, automated verification, and a structured lessons/remediation loop to keep context and quality consistent across sessions.

How to use

You interact with the DevPlan MCP Server through an MCP client. Start a plan, let Claude Code interview you to gather requirements, generate a detailed development plan, and then execute, verify, and learn from the results. Progress is tracked, and insights are captured to improve future projects.

Key workflow you will use:

• Begin planning with inline guidance and interview questions
• Generate a PROJECT_BRIEF.md from your input
• Create a DEVELOPMENT_PLAN.md and pull past lessons learned
• Generate specialized Haiku-powered executor and Sonnet-powered verifier
• Run execution cycles, verify outcomes, and capture lessons for future projects
• Remediate issues by converting GitHub issues into actionable tasks within the plan.

How to install

Prerequisites: you need Node.js and npm installed on your system.

Install the DevPlan MCP Server client integration for Claude Code by adding the MCP server endpoint.

claude mcp add devplan --transport sse https://devplan-mcp-server.mike-c63.workers.dev/sse
"addr": "https://devplan-mcp-server.mike-c63.workers.dev/sse"

Additional sections

Configuration is exposed through the MCP server URL and, if needed, environment variables. The HTTP connection is the primary way to connect to the DevPlan MCP Server.

Usage examples show how to start new projects, check progress, and convert GitHub issues into remediation tasks using dedicated tools.
