# Grain Direction Restrictor MCP for AI Agents MCP

> The Grain Direction Restrictor enforces strict material grain rules when cutting plywood. It prevents waste-inducing errors by calculating the true footprint of pieces based on their required horizontal or vertical orientation during complex bin packing.

## Description

Cutting wood and plywood accurately is hard because you can't just rotate a piece arbitrarily; the structural integrity depends entirely on maintaining the grain direction. This connector solves that problem for manufacturing optimization. Instead of manually checking every single dimension against stock sheet limits, your AI client handles the complex geometry. It uses specialized algorithms to calculate how much space a piece actually takes up when its grain is locked in place. You can process groups of pieces or check individual components, ensuring everything fits within the raw material dimensions and structural requirements. With Vinkius, you connect this capability directly into your workflow, letting your agent handle the geometry checks so you don't waste time on impossible cuts.

## Tools

### evaluate_batch_constraints
Scans an entire group of pieces, checking them for maximum required dimensions and general validity.

### get_oriented_dimensions
Calculates the effective footprint a piece requires based on whether its grain runs horizontally or vertically.

### validate_single_piece
Verifies if one specific, individual component can fit within standard stock sheet dimensions while respecting material rules.

## Prompt Examples

**Prompt:** 
```
I need to check if a 30cm x 75cm part with horizontal grain will fit in my standard 240x120 sheet.
```

**Response:** 
```
**Assessment Status:** ✅ Compatible. The effective footprint required for the piece is 30cm (width) by 75cm (length). This easily fits within the 240cm x 120cm stock dimensions.
```

**Prompt:** 
```
Which parts can I cut from this sheet? We have pieces that are 50x120, and another set at 30x80.
```

**Response:** 
```
**Batch Analysis:** The available sheet size is 240cm x 120cm. **Result:** You cannot fit all parts. The combination of the two sets creates a structural conflict. Specifically, the required dimensions for the combined group exceed the stock width by 5cm.
```

**Prompt:** 
```
Tell me the actual size needed for this piece if I orient it vertically.
```

**Response:** 
```
**Orientation Calculation:** For the component measuring 40cm x 100cm, when oriented vertically (grain running up), the effective footprint is calculated as follows: Width: 40cm; Length: 100cm. This calculation accounts for material stress and structural needs.
```

## Capabilities

### Assess batch constraints
Checks an entire group of pieces to see if they meet maximum required dimensions and structural validity.

### Calculate piece footprint
Determines the effective space a single piece needs based on its grain orientation (horizontal or vertical).

### Verify component fit
Confirms whether any isolated piece of plywood will physically fit inside standard stock sheet dimensions.

## Use Cases

### Checking if custom furniture parts fit a single sheet
A millworker needs to know if three different components, each with specific grain directions, can all be cut from one 4x8 plywood sheet. The agent uses `validate_single_piece` repeatedly and then runs `evaluate_batch_constraints` to confirm the entire set is viable.

### Calculating space for variable components
An operations planner has a batch of parts where some must be oriented vertically and others horizontally. The agent uses `get_oriented_dimensions` on each part type, giving accurate effective footprints to plan the optimal layout.

### Optimizing large-scale pallet cuts
A factory needs to cut thousands of standardized parts from massive sheets. Running `evaluate_batch_constraints` against a predefined set of common part types ensures that no single sheet contains invalid or non-compliant cuts.

## Benefits

- Stop wasting material on impossible cuts. Use the `validate_single_piece` tool to instantly confirm if a component fits before planning.
- Reduce manual checking time drastically. The MCP handles complex grain geometry calculations, letting your agent manage structural constraints automatically.
- Maximize yield potential. By using `get_oriented_dimensions`, you calculate the true effective footprint of pieces, not just their raw length and width.
- Plan entire runs in one go. Run `evaluate_batch_constraints` to check an entire set of parts for compliance with stock sheet limitations simultaneously.
- Avoid costly mistakes. You eliminate waste-inducing errors common in complex bin packing algorithms where rotation is restricted by material properties.

## How It Works

The bottom line is that your agent doesn't just check size; it understands how material properties constrain geometry when planning cuts.

1. You provide the system with a set of raw material pieces and the size of the available stock sheets.
2. The MCP calculates the required effective footprint for each piece, respecting the grain direction constraints, and then checks these against the overall sheet dimensions.
3. Your AI client returns a detailed report on which individual components fit, or if an entire batch violates structural rules.

## Frequently Asked Questions

**How does Grain Direction Restrictor handle complex plywood cutting layouts?**
It solves the layout problem by respecting physics, not just math. It ensures that every piece's required dimensions are calculated based on its grain orientation (horizontal or vertical), preventing waste and structural failure.

**Can I use this MCP to check if one specific component fits in a sheet?**
Yes, you can. Use the tool designed for single components; it checks that an individual piece adheres to both size constraints and material grain direction rules against your stock dimensions.

**Is Grain Direction Restrictor good for optimizing large groups of parts?**
Absolutely. If you have a whole batch of items, the MCP can assess all of them at once. It will tell you if the group meets structural requirements or if specific pieces are causing violations.

**Does Grain Direction Restrictor only work for plywood?**
No. While it's optimized for wood and plywood, its core function is enforcing material grain constraints in any cutting optimization scenario where rotation matters.

**What kind of dimensions does this MCP use for calculating cuts?**
It uses the effective footprint—the true space a piece occupies after factoring in its required grain orientation. This is much more accurate than just using raw measurements.
