|
||||||
|
|
||||||
|
✅ **Completed:**
|
||||||
|
- [x] 3 consolidated tools tested (symbolic_tool, numpy_tool, scipy_tool)
|
||||||
|
- [x] 10 advanced math problems validated
|
||||||
|
- [x] MCP specification compliance verified
|
||||||
|

|
||||||
|
- [x] LICENSE file (MIT)
|
||||||
|

|
||||||
|
|
||||||
|
## Deployment Steps
|
||||||
|
|
||||||
|
### 1. GitHub Repository Setup
|
||||||
|
|
||||||
|
**Create a new repository:**
|
||||||
|
```bash
|
||||||
|
# Initialize git (if not already done)
|
||||||
|
cd F:\AAchengguoofAI\cuz_caculat
|
||||||
|
git init
|
||||||
|
|
||||||
|
# Add all files
|
||||||
|
git add .
|
||||||
|
git commit -m "Initial release: MCP Scientific Calculator v1.0.0"
|
||||||
|
|
||||||
|
# Create GitHub repo and push
|
||||||
|
# Go to https://github.com/new
|
||||||
|
# Repository name: mcp-scientific-calculator
|
||||||
|
# Public repository
|
||||||
|
# Then:
|
||||||
|
git remote add origin https://github.com/YOUR_USERNAME/mcp-scientific-calculator.git
|
||||||
|
git branch -M main
|
||||||
|
git push -u origin main
|
||||||
|
```
|
||||||
|
|
||||||
|
**Repository structure (current):**
|
||||||
|
```
|
||||||
|
mcp-scientific-calculator/
|
||||||
|
├── README.md # ✅ Service introduction (required)
|
||||||
|
├── LICENSE # ✅ MIT License
|
||||||
|
├── setup.py # ✅ PyPI packaging
|
||||||
|
├── pyproject.toml # ✅ Python project metadata
|
||||||
|
├── requirements.txt # ✅ Dependencies
|
||||||
|
├── calculator.py # Core calculation library

|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. PyPI Publishing (Required by MCP Community)
|
||||||
|
|
||||||
|
**Prepare for PyPI:**
|
||||||
|
```bash
|
||||||
|
# Install build tools
|
||||||
|
pip install build twine
|
||||||
|
|
||||||
|
# Build distribution packages
|
||||||
|
python -m build
|
||||||
|
|
||||||
|
# This creates:
|
||||||
|
# dist/mcp-scientific-calculator-1.0.0.tar.gz
|
||||||
|
# dist/mcp_scientific_calculator-1.0.0-py3-none-any.whl
|
||||||
|
```
|
||||||
|
|
||||||
|
**Test with TestPyPI first:**
|
||||||
|
```bash
|
||||||
|
# Upload to TestPyPI
|
||||||
|
python -m twine upload --repository testpypi dist/*
|
||||||
|
|
||||||
|
# Test installation
|
||||||
|
pip install --index-url https://test.pypi.org/simple/ mcp-scientific-calculator
|
||||||
|
```
|
||||||
|
|
||||||
|
**Publish to PyPI:**
|
||||||
|
```bash
|
||||||
|
# Create PyPI account at https://pypi.org/account/register/
|
||||||
|
# Create API token at https://pypi.org/manage/account/token/
|
||||||
|
|
||||||
|
# Upload to PyPI
|
||||||
|
python -m twine upload dist/*
|
||||||
|
|
||||||
|
# Installation command (for users):
|
||||||
|
pip install mcp-scientific-calculator
|
||||||
|
```
|
||||||
|
|
||||||
|

|
## Troubleshooting
|
||||||
|
|
||||||
|
**Tools not appearing in Claude Desktop:**
|
||||||
|
- Check config file syntax (valid JSON)
|
||||||
|
- Verify Python path in "command" field
|
||||||
|
- Ensure all dependencies installed: `pip install sympy numpy scipy pandas`
|
||||||
|
- Restart Claude Desktop after config changes
|
||||||
|
|
||||||
|
**Import errors:**
|
||||||
|
- Install missing packages: `pip install -r requirements.txt`
|
||||||
|
- Verify Python version ≥ 3.8
|
||||||
|
|
||||||
|
**Tool execution errors:**
|
||||||
|
- Check input format (JSON strings for arrays/matrices)
|
||||||
|
- Review operation name spelling
|
||||||
|

## Usage Examples
|
||||||
|
|
||||||
|
```python
|
||||||
|
from calculator import CALCULATOR_TOOLS
|
||||||
|
|
||||||
|
# Derivative: d(x³)/dx = 3x²
|
||||||
|
result = CALCULATOR_TOOLS['symbolic_derivative']('x**3', 'x')
|
||||||
|
|
||||||
|
# Solve: x² - 4 = 0
|
||||||
|
result = CALCULATOR_TOOLS['solve_equation']('x**2 - 4', 'x')
|
||||||
|
|
||||||
|
# Eigenvalues of matrix
|
||||||
|
import numpy as np
|
||||||
|
A = [[1, 2], [3, 4]]
|
||||||
|
result = CALCULATOR_TOOLS['numpy_linear_algebra'](A, 'eigenvalues')
|
||||||
|
|
||||||
|
# Integrate: ∫ x² dx from 0 to 1
|
||||||
|
result = CALCULATOR_TOOLS['symbolic_integral']('x**2', 'x', 0, 1)
|
||||||
|
```
|
||||||
|
|
||||||
|
## Model Usage Policy
|
||||||
|
|
||||||
|
- Every numeric or symbolic calculation must be delegated to the tools (via MCP `tools/call` or direct `CALCULATOR_TOOLS[...]`), never hand-compute inside the model response.
|
||||||
|
- Reasoning flow: pick the right tool → prepare JSON-safe inputs → call the tool → present the tool output (with minimal post-processing only for formatting).
|
||||||
|
- If a step would require arithmetic, call a tool instead (e.g., use `numpy_linear_algebra` for matrices, `symbolic_*` for algebra, `scipy_*` for calculus/optimization).
|
||||||
|
- Avoid approximations unless the tool returns them; do not estimate values manually.
|
||||||
|
|
||||||
|
### Prompting Playbook (Advanced Problems)
|
||||||
|
- Restate the task, list the required sub-calculations, and map each to a tool.
|
||||||
|
- For matrices, always supply `matrix_a` (and `matrix_b` when needed) as JSON arrays to `numpy_linear_algebra`.
|
||||||
|
- For calculus/ODE/PDE, convert expressions to plain strings (SymPy-compatible) before calling `symbolic_*` or `scipy_*` tools.
|
||||||
|
- After each tool call, reuse its exact output for subsequent steps—no manual arithmetic in between.
|
||||||
|
- When summing or solving, prefer tool outputs as inputs to the next tool (e.g., eigenvalues → use in later steps instead of recomputing).
|
||||||
|
- If the user asks for a result, return: the tool(s) called, inputs used, and the tool outputs; avoid “mental math.”
|
||||||
|
|
||||||
|
## Problem Set
|
||||||
|
|
||||||
|
10 complex university-level problems demonstrating the tool capabilities:
