[Good First Issue] Test ACE MCP server with non-VS Code clients

[erwinh22]

Objective

Test and verify ACE MCP server workspace detection and auto-onboarding with non-VS Code MCP clients (Claude Desktop, Cursor, etc.).

Context

The ACE MCP server uses the MCP list_roots() protocol for automatic workspace detection. The implementation in ace_mcp_server.py includes a 6-level fallback system:

1. MCP list_roots() protocol (primary)
2. ACE_WORKSPACE_PATH environment variable
3. MCP_WORKSPACE_FOLDER environment variable
4. Project marker detection (.git, package.json, pyproject.toml, etc.)
5. Current working directory
6. Invalid path exclusion (home, temp, drive roots)

Recent Changes

• Updated error messages to be client-agnostic (no longer mention "VS Code")
• Updated VSCODE_INTEGRATION.md to MCP Integration Guide with client-specific configs
• Added Claude Desktop and Cursor configuration examples

Verification Steps

For each MCP client (Claude Desktop, Cursor, others):

1. Install ACE MCP server in client's config
2. Open a project folder in the client
3. Call ace_workspace_info tool
   • Verify workspace path is detected correctly
   • Check if error messages are clear (not mentioning VS Code)
4. Call ace_onboard tool if not already onboarded
   • Verify .ace/.ace.json is created
   • Check workspace name is derived correctly
5. Call ace_retrieve with a code-related query
   • Verify both code context AND memory context are returned
   • Check that retrieval works for the workspace

Acceptance Criteria

• Workspace detected via list_roots() (no env vars needed)
• Auto-onboarding creates .ace/.ace.json with correct workspace name
• Code retrieval returns workspace-specific results
• Error messages don't mention VS Code when workspace not found
• Documentation accurately reflects the tested client's setup

Additional Notes

• Qdrant must be running: docker run -d -p 6333:6333 qdrant/qdrant
• Required env vars: VOYAGE_API_KEY, ZAI_API_KEY (or OPENAI_API_KEY)
• Report findings as a comment or PR
