Quick Start

1. Add to your MCP configuration

Claude Code CLI (recommended - uses current directory):

claude mcp add openspec -- npx openspec-mcp

Claude Code CLI with Dashboard:

claude mcp add openspec -- npx openspec-mcp --with-dashboard

Claude Code CLI with specific project path:

claude mcp add openspec -- npx openspec-mcp /path/to/your/project

Claude Desktop / Cursor / Other:

{
  "mcpServers": {
    "openspec": {
      "command": "npx",
      "args": ["-y", "openspec-mcp"]
    }
  }
}

With Dashboard:

{
  "mcpServers": {
    "openspec": {
      "command": "npx",
      "args": ["-y", "openspec-mcp", "--with-dashboard"]
    }
  }
}

Cross-Service Documentation

For multi-service projects sharing a common .cross-service/ directory (e.g., in a Git worktree), configure your proposal.md frontmatter:

---
crossService:
  rootPath: "../../../../.cross-service" # Relative to change directory
  documents:
    - design.md
    - flows.md
    - services.yaml
  archivePolicy: snapshot # 'snapshot' (default) or 'reference'
---
# Your proposal content...

The Dashboard will display a "Cross-Service" tab with:

• design.md / flows.md: Rendered as Markdown

• services.yaml: Visual card view with service status, changes, and deployment order

Approval Workflow

draft -> pending_approval -> approved -> implementing -> completed -> archived
                         -> rejected -> draft (revise and resubmit)

Approval records are stored in openspec/approvals/<change-id>.json.
