Example Workflows

Example 1: Solving a Physics Problem

1. Open an existing MathCAD worksheet:
   "Can you open my physics worksheet at C:\Users\username\Documents\Physics\projectile_motion.mcdx?"
2. Set input parameters:

   "Set the initial velocity to 50 m/s and the launch angle to 30 degrees."
3. Calculate the results:

   "Now calculate the trajectory and show me the maximum height and distance."
4. Extract output values:

   "What's the maximum height reached by the projectile?"

Example 2: Engineering Analysis

1. Open or create a worksheet for analysis:
   "I need to analyze a beam deflection problem. Can you open the structural_analysis.mcdx worksheet?"
2. Configure the worksheet:

   "Set the load P to 5000 N, beam length L to 2 m, Young's modulus E to 200 GPa, and moment of inertia I to 4×10⁻⁶ m⁴."
3. Run the calculation:

   "Calculate the worksheet and tell me the maximum deflection."
4. Export the results:

   "Save the worksheet as a PDF so I can include it in my report."

Environment Variables

- MATHCAD_VISIBLE: Set to "true" to show the MathCAD application window (default), or "false" to hide it.

Architecture

The server is built using the MCP Python SDK's FastMCP framework. The main components are:

- standalone.py: Self-contained server script with MathCAD integration
- install_standalone.py: Utility script to install the server in Claude Desktop

Troubleshooting

Common Issues

COM Automation Errors

If you encounter COM automation errors:
- Ensure MathCAD is installed and properly licensed
- Check that you're running on Windows
- Try restarting MathCAD and the MCP server

Worksheet Not Found

If worksheets can't be found:
- Use absolute paths, not relative paths
- Ensure file paths are correctly escaped
- Verify the file exists and is a valid .mcdx file

Unit Conversion Issues

If unit conversion fails:
- Check for compatibility between units (e.g., length can't convert to mass)
- Ensure that the right unit symbols are used (e.g., 'm' for meters)
- Try using standard unit formats (e.g., 'm/s' instead of 'm*s^(-1)')
