Agent Context Explorer (ACE)

View project context for AI agents — Cursor and Claude Code rules, commands, skills, and project specs in one tree. Browse across multiple workspaces. ACE is viewer-only: it scans and displays intentional artifacts without managing them.

What You See

Workspaces view — project-level artifacts for every workspace and added project:

• Cursor — .cursor/rules/*.{mdc,md}, .cursor/commands/*.md, .cursor/skills/*/SKILL.md
• Claude Code — CLAUDE.md, .claude/rules/*.{mdc,md}, .claude/commands/*.md, .claude/skills/*/SKILL.md
• Specs — specs/*/spec.md feature specifications

Global commands and skills (~/.cursor/commands/, ~/.cursor/skills/) are shown alongside workspace artifacts in the Cursor section.

Agents view — user-level agent configuration across all three global roots:

The view auto-refreshes within seconds when files are added, changed, or removed from any watched path.

Quick Start

1. Open the ACE icon in the Activity Bar.
2. Expand Workspaces to browse Cursor and Claude Code artifacts for your project.
3. Expand Agents to browse your global agent configuration across ~/.cursor/, ~/.claude/, and ~/.agents/.
4. Click any item to open it read-only in your editor.

Multi-Project

Use the + button to add external projects. Each project shows its own rules, commands, skills, and specs independently.

MCP: AI Agent Access

ACE exposes an MCP server so AI agents can query project context on demand.

In Cursor: ACE registers automatically via the VS Code MCP Extension API — no setup needed.

Standalone / fallback: Add to .cursor/mcp.json or ~/.cursor/mcp.json:

{
  "mcpServers": {
    "ace": {
      "command": "node",
      "args": ["<extension-dir>/out/mcp/server.js", "<workspace-root>"]
    }
  }
}

Replace <extension-dir> (e.g. ~/.cursor/extensions/fancy-bread.agent-context-explorer-x.y.z) and <workspace-root> with your actual paths.

Available tools: list_projects, get_project, list_rules, get_rule, list_commands, get_command, list_skills, get_skill, list_agents, get_agent, list_specs, get_spec

Requirements

VS Code or Cursor ^1.105.0 (see engines.vscode in package.json).
