Using Stellarion with Cursor IDE

Stellarion can be used with Cursor IDE through its MCP support.

Setup

1. Install Stellarion

npm install -g @stellarion/stellarion-mcp

2. Configure Cursor

Add Stellarion to your Cursor MCP configuration. Save as .cursor/mcp.json in your project root (project-scope) or ~/.cursor/mcp.json (global).

{
  "mcpServers": {
    "stellarion": {
      "command": "stellarion-mcp",
      "args": [
        "--workspace", "/absolute/path/to/your/project"
      ]
    }
  }
}

3. EDA Mode (Quartus / Qsys / SDC)

For hardware-design teams: pass --mode eda to filter the tool surface for EDA workflows. Hides tools that don't apply to HDL/Tcl (scan_security, find_implementors, find_related_tests, cross_project_search) and surfaces three EDA-native Pro tools (find_eda_calls, get_flow_graph, find_duplicate_constraints).

{
  "mcpServers": {
    "stellarion": {
      "command": "stellarion-mcp",
      "args": [
        "--workspace", "/absolute/path/to/your/eda/project",
        "--mode", "eda"
      ]
    }
  }
}

EDA mode requires a Pro license or active 180-day trial.

4. Restart Cursor

Restart Cursor to load the new MCP server configuration.

Using Stellarion in Cursor

Once configured, you can ask Cursor's AI assistant to use Stellarion tools:

Tips

Stellarion tools work best when you're in a project directory
Index large projects for better semantic search
Use specific queries for more accurate results
For multi-repo projects, pass --workspace multiple times

Troubleshooting

Tools Not Available

If Stellarion tools aren't appearing:

Check that Stellarion is installed globally: npm list -g @stellarion/stellarion-mcp
Verify the MCP configuration in .cursor/mcp.json
Restart Cursor

Connection Issues

If you see connection errors:

Check that no other instance is running
Verify Stellarion starts correctly: stellarion-mcp --info
Check Cursor's MCP logs for errors
