DevPlan MCP Server

What is DevPlan MCP Server?

An MCP server that implements the ClaudeCode-DevPlanBuilder methodology, creating detailed, agent-executable development plans with built-in validation, lessons learned, and inline git workflows. It runs on Cloudflare Workers and exposes 21 tools for planning, generation, validation, execution, and learning.

How to use DevPlan MCP Server?

Install via claude mcp add devplan --transport sse https://mcp.devplanmcp.store/sse --scope user or add to ~/.claude.json. Then invoke with a description like "Use devplan_start to help me build a CLI tool for managing dotfiles".

Key features of DevPlan MCP Server

• 21 specialized planning, generation, validation, and execution tools.
• Agent-executable plans that any LLM can follow mechanically.
• Built-in validation checks for complete code and no placeholders.
• Real-time progress tracking using Claude Code’s Task tools.
• Lessons learned system captures issues for future plans.
• Multi‑model support for Claude, Cursor, Aider, Cline, Windsurf, and generic.

Use cases of DevPlan MCP Server

• Starting a new project from an idea by generating a structured brief and plan.
• Converting a GitHub issue into a remediation task with devplan_issue_to_task.
• Monitoring completion status and next actions with devplan_progress_summary.
• Generating agent files for different coding tools (Cursor, Aider, etc.) via target parameter.
• Iteratively improving plans by capturing lessons from verification failures.

FAQ from DevPlan MCP Server

What is the difference between the Skill and the MCP Server?

The Skill runs locally as a Claude Code plugin with no network dependency, while the MCP Server connects via SSE to Cloudflare and includes a built-in lessons learned KV store. The server is subject to SSE timeouts; the skill is always usable offline.

How do I install the DevPlan MCP Server?

Run claude mcp add devplan --transport sse https://mcp.devplanmcp.store/sse --scope user. If you have an existing installation, remove it from both user and project scopes first, then re-add.

What tools does DevPlan MCP Server provide?

21 tools grouped into planning (e.g., devplan_start, devplan_create_brief), generation (devplan_generate_plan, devplan_generate_executor), validation & execution (devplan_validate_plan, devplan_update_progress), and lessons learned (devplan_add_lesson).

Can I use DevPlan with other AI coding tools besides Claude Code?

Yes. The MCP server supports multiple targets: claude, cursor, aider, cline, windsurf, and generic. Use the target parameter when generating plans or agent files to get tool‑specific formats (e.g., .cursorrules for Cursor).

How does the lessons learned system work?

During verification, issues are captured as lessons and injected into future plans. The MCP server stores lessons in a built-in KV store; the skill version relies on external tools like Nellie.
