## Overview
The [Model Context Protocol](https://modelcontextprotocol.io/) is an open standard from Anthropic that allows AI assistants to securely connect to external tools and data sources. This implementation provides a standardized bridge between AI assistants and KiCAD, enabling natural language control of professional PCB design operations.

# KiCAD IPC Backend Implementation Status
**Status:** 🟢 **FULLY INTEGRATED**
**Date:** 2025-11-30
**Status:** Under Active Development and Testing

**KiCAD Version:** 9.0.6
**kicad-python Version:** 0.5.0

## Overview
The IPC backend is now **fully integrated** as the **default backend** for all MCP tools. When KiCAD is running with IPC enabled, all commands automatically use real-time UI synchronization. Changes made through the MCP tools appear **instantly** in the KiCAD UI without requiring manual reload.
The IPC backend provides real-time UI synchronization with KiCAD 9.0+ via the official IPC API. When KiCAD is running with IPC enabled, commands can update the KiCAD UI immediately without requiring manual reload.
**SWIG backend is deprecated** and will be removed in a future version when KiCAD removes it (KiCAD 10.0).
This feature is experimental and under active testing. The server uses a hybrid approach: IPC when available, automatic fallback to SWIG when IPC is not connected.

## Known Limitations
1. **KiCAD must be running**: Unlike SWIG, IPC requires KiCAD to be open
2. **Project creation**: Must be done through KiCAD UI or file system
3. **Footprint library access**: Limited - best to use library management separately
4. **Layer management**: Layers are predefined in KiCAD
2. **Project creation**: Not supported via IPC, uses file system
3. **Footprint library access**: Uses hybrid approach (SWIG loads from library, IPC places)
4. **Delete trace**: Falls back to SWIG (IPC API doesn't support direct deletion)
5. **Some operations may not work as expected**: This is experimental code

**Symptoms:**
```
Error: Could not find footprint library

**Root Cause:** MCP server doesn't have access to KiCAD's footprint library paths
**Workaround:** None currently - feature not usable
**Fix Plan:** Week 2 priority
- Detect KiCAD library paths from environment
- Add configuration for custom library paths
- Integrate JLCPCB/Digikey part databases
**Tracking:** High Priority - Required for any real PCB design

**Affected Commands:**
- `route_trace`
- `add_via`
- `add_copper_pour`
- `route_differential_pair`

- Test each routing command with KiCAD 9.0
- Fix API compatibility issues
- Add comprehensive routing examples

- Add backward compatibility for KiCAD 8.x

### 4. UI Auto-Reload Requires Manual Confirmation
### 2. Zone Filling via SWIG Causes Segfault
**Status:** 🟢 **BY DESIGN** - Will be fixed by IPC
**Status:** KNOWN - Workaround available
**Symptoms:**
- MCP makes changes
- KiCAD detects file change
- User must click "Reload" button to see changes
- Copper pours created but not filled automatically when using SWIG backend
- Calling `ZONE_FILLER` via SWIG causes segfault
**Workaround Options:**
1. Use IPC backend (zones fill correctly via IPC)
2. Open the board in KiCAD UI - zones fill automatically when opened
**Impact:** Medium - affects copper pour visualization until opened in KiCAD

- MCP makes changes via SWIG backend
- KiCAD doesn't show changes until file is reloaded

## 🔧 Recently Fixed
### 4. IPC Backend Experimental
### ✅ KiCAD Process Detection (Fixed 2025-10-26)
**Status:** UNDER DEVELOPMENT
**Description:**
The IPC backend is currently being implemented and tested. Some commands may not work as expected in all scenarios.
**Known IPC Limitations:**
- KiCAD must be running with IPC enabled
- Some commands fall back to SWIG (e.g., delete_trace)
- Footprint loading uses hybrid approach (SWIG for library, IPC for placement)
- Error handling may not be comprehensive in all cases
**Workaround:** If IPC fails, the server automatically falls back to SWIG backend
---
### 5. Schematic Support Limited
**Status:** KNOWN - Partial support
**Description:**
Schematic operations use the kicad-skip library which has some limitations with KiCAD 9.0 file format changes.
**Affected Commands:**
- `create_schematic`
- `add_schematic_component`
- `add_schematic_wire`
**Workaround:** Manual schematic creation may be more reliable for complex designs

## IPC Backend (Under Development)
We are currently implementing and testing the KiCAD 9.0 IPC API for real-time UI synchronization. This is experimental and may not work perfectly in all scenarios.
### IPC-Capable Commands (21 total)
The following commands have IPC handlers implemented:
| Command | IPC Handler | Notes |
|---------|-------------|-------|
| `route_trace` | `_ipc_route_trace` | Implemented |
| `add_via` | `_ipc_add_via` | Implemented |
| `add_net` | `_ipc_add_net` | Implemented |
| `delete_trace` | `_ipc_delete_trace` | Falls back to SWIG |
| `get_nets_list` | `_ipc_get_nets_list` | Implemented |

| `get_component_properties` | `_ipc_get_component_properties` | Implemented |
| `save_project` | `_ipc_save_project` | Implemented |
### How IPC Works
When KiCAD is running with IPC enabled:
1. Commands check if IPC is connected
2. If connected, use IPC handler for real-time UI updates
3. If not connected, fall back to SWIG API
**To enable IPC:**
1. KiCAD 9.0+ must be running
2. Enable IPC API: `Preferences > Plugins > Enable IPC API Server`
3. Have a board open in the PCB editor
### Known Limitations
- KiCAD must be running for IPC to work
- Some commands may not work as expected (still testing)
- Footprint loading uses hybrid approach (SWIG for library, IPC for placement)
- Delete trace falls back to SWIG (IPC API limitation)

## What Needs Work
### Minor Issues (NON-BLOCKING)
@@ -104,67 +149,37 @@
- Error: `AttributeError: 'BOARD' object has no attribute 'LT_USER'`
- Impact: Low (informational command only)
- Workaround: Use `get_project_info` or read components directly
- Fix: Update layer constants for KiCAD 9.0 (30 min task)
**2. Zone filling**
- Copper pours created but not filled automatically
**2. Zone filling via SWIG**
- Copper pours created but not filled automatically via SWIG
- Cause: SWIG API segfault when calling `ZONE_FILLER`
- Workaround: Zones are filled automatically when opened in KiCAD UI
- Fix: Will be resolved with IPC backend (Week 3)
- Workaround: Use IPC backend or zones are filled when opened in KiCAD UI
**3. UI manual reload**
- User must manually reload to see MCP changes
- Impact: Workflow friction (~2 seconds)
- Workaround: File → Revert or close/reopen PCB editor
- Fix: IPC backend will enable automatic refresh (Week 3)

## Current Progress
### Week 2 Goals (NEARLY COMPLETE)
**Must Have:**
1. **Component library integration** → 153 libraries auto-discovered, search working
2. **Routing operations** → All operations tested and working with KiCAD 9.0
3. **JLCPCB integration** → Planned and designed, ready to implement
**Should Have:**
4. Fix `get_board_info` API issue (deferred, low priority)
5. Create example project (LED blinker)
6. Real-time collaboration documented
**Bonus Achievements:**
- Real-time collaboration workflow tested end-to-end
- Comprehensive documentation (3 new docs created)
- All KiCAD 9.0 API compatibility issues resolved
### Overall v2.0 Progress
```
Week 1: ████████████████████ 100% Linux support + IPC prep
Week 2: ████████████████░░░░ 80% Libraries + Routing + Real-time
Week 3: ░░░░░░░░░░░░░░░░░░░░ 0% IPC Backend (next)
...
Overall: ████████░░░░░░░░░░░░ 40%
```
**Production Readiness:** 75% - Can design and manufacture PCBs, needs IPC for optimal UX
**3. UI manual reload (SWIG mode)**
- User must manually reload to see MCP changes when using SWIG
- Impact: Workflow friction
- Workaround: Use IPC backend for automatic updates

## Architecture Status
### SWIG Backend (Current) **PRODUCTION READY**
- **Status:** Stable and fully functional
### SWIG Backend (File-based)
- **Status:** Stable and functional
- **Pros:** No KiCAD process required, works offline, reliable
- **Cons:** Requires manual file reload for UI updates, no zone filling
- **Future:** Will be maintained alongside IPC as fallback/offline mode
- **Use Case:** Offline work, automated pipelines, batch operations
### IPC Backend (Week 3) **NEXT PRIORITY**
- **Status:** Planned, not yet implemented
- **Pros:** Real-time UI updates (<100ms), no file I/O, zone filling works
- **Cons:** Requires KiCAD running, more complex
- **Future:** Primary backend for interactive use
### IPC Backend (Real-time)
- **Status:** Under active development and testing
- **Pros:** Real-time UI updates, no file I/O for many operations, zone filling works
- **Cons:** Requires KiCAD running, experimental
- **Use Case:** Interactive design sessions, paired programming with AI
### Hybrid Approach
The server automatically selects the best backend:
- IPC when KiCAD is running with IPC enabled
- SWIG fallback when IPC is unavailable
