Upstream commit 2b38796 downgraded template_with_symbols.kicad_sch and
template_with_symbols_expanded.kicad_sch from version 20250114 to 20240101.
KiCAD 9 requires version 20250114 - files with older versions cause parse
errors or are rejected. This was originally fixed in ce78fb4.
Convenience wrapper around route_trace that eliminates the need for
separate get_pad_position calls before routing.
- Accepts fromRef/fromPad/toRef/toPad instead of raw coordinates
- Automatically looks up pad positions from board footprints
- Auto-detects net from pad assignment (overridable via net param)
- Returns fromPad/toPad position info in response
- Saves ~2 tool calls (64+ calls for a full TMC2209 board) vs 3-step flow
Registered in: routing.py, kicad_interface.py (dispatch), routing.ts (MCP)
- fix: DynamicSymbolLoader reads project sym-lib-table before global dirs
add_schematic_component now finds symbols from project-local .kicad_sym files
project_path derived automatically from schematic file path
- fix: place_component reloads FootprintLibraryManager with project_path
new boardPath parameter passed to place_component tool (TypeScript + Python)
_handle_place_component wrapper recreates LibraryManager per project
- fix: copy_routing_pattern geometric fallback when pads have no nets
primary filter: net-based (when pads are assigned to nets)
fallback: bounding box of source footprint pads +5mm tolerance
filterMethod field in response indicates which mode was used
- feat: register copy_routing_pattern as MCP tool in routing.ts
sourceRefs, targetRefs, includeVias, traceWidth parameters
Live tested: ESP32 + 2x TMC2209 in Test3 project
13 traces U2 routed, copy_routing_pattern copied all 13 to U3
offset Y+30mm correct, 26 total traces verified
- Update schematic version from 20230121 (KiCAD 7) to 20240101 (KiCAD 9)
- Replace invalid all-zeros UUIDs in template files with valid UUIDs
- Add post-copy UUID regeneration to ensure each project gets unique UUID
- Add UTF-8 encoding and Unix line endings for cross-platform compatibility
Fixes the root cause where templates were copied with invalid UUIDs and
outdated version format, causing KiCAD 9.0.x to reject the schematic files.

Bug fixes + new tool, discovered via live testing on a real JLCPCB/KiCAD 9 project.
### Changes
1. **Format version bump**: KiCAD 7 → KiCAD 9 (`20230121` → `20250114`)
MCP server targets KiCAD 9 exclusively. Every newly created schematic showed spurious "older version" warning.
2. **Remove corrupt `_TEMPLATE_*` placed-symbol blocks** (`lib_id -100` crash)
13 blocks with `(lib_id -100)` caused KiCAD null-pointer crash on box-select.
Same sexpdata serializer root cause as PR #40.
3. **Fix footprint param silently ignored** in `add_schematic_component`
The `footprint` field was never passed through the call chain to the f-string in `DynamicSymbolLoader`.
4. **Fix `delete_schematic_component` only deleting first duplicate**
`break` after first match replaced with full scan + back-to-front deletion. Response now includes `deleted_count`.
5. **New tool: `edit_schematic_component`**
Update `footprint`, `value`, and/or `reference` in-place on an existing placed symbol.
Bug 1 - add_schematic_component: footprint parameter silently ignored
The footprint value from MCP params was never passed through to
DynamicSymbolLoader.add_component() / create_component_instance().
Every placed symbol had an empty Footprint field regardless of input.
Fix: added footprint: str='' to both functions, passed through all
call sites, added footprint to schematic.ts tool schema.
Bug 2 - delete_schematic_component: only deleted first duplicate
When a reference appeared multiple times (e.g. after a failed
add attempt), only the first instance was removed due to break
after first match. Fix: collect all matching blocks first, then
delete back-to-front to preserve indices. Response now includes
deleted_count.
New tool - edit_schematic_component
Update footprint, value or reference of a placed symbol in-place.
More efficient than delete+re-add: preserves position and UUID.
Accepts: schematicPath, reference, footprint?, value?, newReference?
All 3 fixes verified by live tests on a real JLCPCB/KiCAD 9 project:
- R_TEST1: footprint Resistor_SMD:R_0603_1608Metric written correctly
- J1 duplicate: deleted_count=2 with single call
- J2 edit: PinSocket footprint assigned in-place, no delete+add needed
- PCB update (F8) confirmed: only components with footprint imported
Verified by live test: created a fresh schematic via MCP, result shows
format version 20250114, 0 _TEMPLATE_ hits, 0 (lib_id -100) hits, 24
real components placed cleanly.
--- Format version bump (20230121 KiCAD 7 -> 20250114 KiCAD 9) ---
Files: python/templates/*.kicad_sch, python/commands/project.py,
python/commands/schematic.py
Root cause: the MCP server targets KiCAD 9 exclusively - pcbnew.pyd is
compiled for KiCAD 9.0 / Python 3.11.5, and server.ts explicitly selects
the KiCAD 9 bundled Python on Windows. Generating new schematics with a
2-year-old format tag caused a spurious 'This file was created with an
older KiCAD version' warning on every newly created schematic.
--- Remove corrupt _TEMPLATE_* placed-symbol blocks ---
File: python/templates/template_with_symbols_expanded.kicad_sch
Root cause: the expanded template was generated by the old sexpdata
serializer (same corruption PR #40 fixed for DynamicSymbolLoader add-path).
The serializer converted the string 'Device:R' to integer -100, producing
(lib_id -100) instead of (lib_id Device:R). KiCAD cannot resolve an
integer as a library reference and crashes with a null-pointer when the
user attempts to select these symbols. They appeared as grey _TEMPLATE_R?,
_TEMPLATE_C?, _TEMPLATE_U_REG? etc. ~5000mm off-sheet - invisible during
normal work but triggering a crash on accidental box-select.
Discovered via live testing on a real JLCPCB/KiCAD 9 project.
New tools - datasheet:
- get_datasheet_url: construct LCSC datasheet PDF URL + product page URL
without any API key (URL schema: https://www.lcsc.com/datasheet/<C#>.pdf)
- enrich_datasheets: scan .kicad_sch, write LCSC datasheet URL into every
symbol that has an LCSC property but an empty Datasheet field; supports
dry_run=true for preview; text-based implementation (no skip writes)
Implementation: python/commands/datasheet_manager.py
New tool - schematic:
- delete_schematic_component: remove a placed symbol from a .kicad_sch file
by reference designator (e.g. R1, U3)
Bug fix - delete_schematic_component (two separate root causes):
1. No MCP tool named delete_schematic_component was registered at all.
Any delete-symbol request fell through to the PCB-only delete_component
tool which searches pcbnew.BOARD and always returned 'Component not found'
for schematic symbols.
2. component_schematic.py::remove_component() still used skip for writes.
PR #40 rewrote DynamicSymbolLoader (add path) to avoid skip-induced
schematic corruption, but the delete path was not touched by that PR.
Fix: _handle_delete_schematic_component in kicad_interface.py uses direct
text manipulation with parenthesis-depth tracking (same technique as PR #40),
bypassing component_schematic.py entirely. Error message explicitly guides
users: 'use delete_component for PCB footprints'.
Files changed:
- python/commands/datasheet_manager.py (new)
- src/tools/datasheet.ts (new)
- python/kicad_interface.py: 3 new handlers + dispatch entries
- src/tools/schematic.ts: delete_schematic_component tool
- src/server.ts: registerDatasheetTools import + call
- src/tools/index.ts: export registerDatasheetTools
- CHANGELOG.md: document all above
- connection_schematic.py: generate_netlist() now accepts schematic_path param,
threaded through to get_net_connections() so PinLocator is actually invoked
(previously only 1 connection per component was returned due to fallback break)
- kicad_interface.py: pass schematic_path to generate_netlist()
- pin_locator.py: add _schematic_cache to avoid loading Schematic() once per pin
(was causing timeout: O(nets x components x pins) Schematic() calls)
- server.ts: remove fragile PYTHONPATH?.includes('KiCad') condition,
always prefer KiCAD bundled Python on Windows when executable exists
- CHANGELOG.md: document fixes under v2.2.0-alpha
Fixes Issue #26 - add_schematic_component corrupts .kicad_sch files
Complete rewrite of DynamicSymbolLoader to use text manipulation instead of sexpdata:
- Preserves KiCAD file formatting perfectly
- Correctly handles KiCAD 9 symbol naming conventions (library prefix for top-level, no prefix for sub-symbols)
- Resolves parent-child symbol dependencies with (extends)
- Adds symbol caching for performance
- Simplifies component addition workflow
Tested on KiCAD 9.0.7 with R, C, LED, ESP32, and transistor components.
Compatible with recent Windows fixes (UUID generation, IPC, JLCPCB).

This commit fixes the critical bug where the MCP server fails to start on
Linux with "Python executable not found: python3" even when python3 is
correctly installed and available in PATH.
Root Cause:
- findPythonExecutable() returned 'python3' (command name) on Linux
- validatePrerequisites() used existsSync('python3') which checks current
directory, not PATH
- Validation failed even though spawn() would resolve 'python3' via PATH
Changes Made:
1. Enhanced findPythonExecutable() for Linux (src/server.ts:42-126):
- Added Linux platform detection
- Check KiCad bundled Python paths first (/usr/lib/kicad/bin/python3, etc.)
- Use 'which python3' to resolve system python3 to absolute path
- Fallback to common system paths (/usr/bin/python3, /bin/python3)
- Import execSync for 'which' command execution
2. Improved validatePrerequisites() (src/server.ts:214-266):
- Distinguish between absolute paths and command names
- Use existsSync for absolute paths
- Use --version execution test for command names
- Added Linux-specific error messages and troubleshooting
3. Documentation Updates (README.md:409-444):
- Added "Linux Python Detection" section
- Documented detection priority order
- Added troubleshooting steps for KICAD_PYTHON
- Clarified that no manual config needed for standard installations
Testing:
- Build completed successfully (npm run build)
- Python detection now resolves /usr/bin/python3 on Ubuntu/Debian
- Maintains backward compatibility with Windows/macOS
- KICAD_PYTHON override still works

Fixes issue #28 where place_component fails on KiCAD 9.0.5 with:
'FOOTPRINT' object has no attribute 'SetFootprintName'
KiCAD 9.x API changed from SetFootprintName() to SetFPID(LIB_ID).
Changes:
- place_component: Parse footprint string and use SetFPID with LIB_ID
- update_component: Parse footprint string or preserve existing library
- duplicate_component: Use source.GetFPID() directly
All three methods now use the KiCAD 9.x API while maintaining backward
compatibility with the footprint parameter format.

Critical Bug Fixes:
1. Changed get_or_create_template() return type to tuple (template_ref, needs_reload)
2. Added automatic schematic reload after dynamic loading
3. Replaced hasattr() checks with symbol iteration (handles special characters like +)
4. Added template_exists() helper function
5. Fixed template lookup to check multiple potential reference formats
Issues Resolved:
- Multiple components of same type can now be added after dynamic loading
- Power symbols with special characters (+3V3, +5V) work correctly
- Template references with library prefix are properly detected
- Schematic object stays in sync with file after dynamic injections
Testing:
- ✅ Power symbols: 4/4 loaded (VCC, GND, +3V3, +5V)
- ✅ Components: 4/4 placed (R, R, C, LED)
- ✅ Connections: 8/8 created
- ✅ Special character handling (+3V3, +5V) working
Technical Details:
- hasattr() fails with attribute names containing special characters
- Must iterate symbols and check Reference.value directly
- Schematic reload required after S-expression injection
- Template name formats: _TEMPLATE_R, _TEMPLATE_power_VCC, _TEMPLATE_Device_R
Addresses template mapping issues found during Phase 2 power net testing

MAJOR MILESTONE: Dynamic symbol loading is now fully integrated through the MCP interface!
## What's Working
✅ **Full MCP Integration**
- Modified _handle_add_schematic_component to orchestrate dynamic loading
- Detects when symbols need dynamic loading (not in static templates)
- Automatically saves → injects → reloads → clones → saves workflow
✅ **ComponentManager Integration**
- Added schematic_path parameter to add_component() and get_or_create_template()
- Seamlessly switches between static templates and dynamic loading
- Proper error handling and fallback mechanisms
✅ **Smart Detection**
- Checks if component type is in static template map
- Verifies template exists in current schematic
- Only triggers dynamic loading when truly needed
✅ **Reload Orchestration**
- Saves schematic before dynamic loading (preserves changes)
- Calls DynamicSymbolLoader.load_symbol_dynamically()
- Reloads schematic to get newly injected symbols
- Clones from reloaded templates
## Test Results
End-to-end integration test: ✅ **100% PASSING**
Components tested:
- R (resistor) - static template, dynamically loaded
- C (capacitor) - static template, dynamically loaded
- Battery - pure dynamic loading ✨
- Fuse - pure dynamic loading ✨
- Transformer_1P_1S - pure dynamic loading ✨
All 5 components added successfully!
## Impact
Users can now add **ANY symbol from KiCad's ~10,000 symbol libraries** through the MCP interface!
No more limitation to 13 pre-configured templates!
## Technical Details
1. MCP handler detects dynamic loading need
2. Saves current schematic state
3. Calls dynamic loader (injects symbol + creates template)
4. Reloads schematic (kicad-skip sees new template)
5. Clones template to create component
6. Saves final result
Response includes:
- success status
- dynamic_loading_used flag
- symbol_source (library:symbol)
- template_reference
## Files Modified
- python/kicad_interface.py: _handle_add_schematic_component - full orchestration
- python/commands/component_schematic.py: add_component() and get_or_create_template() - schematic_path support
## Time Estimate vs Actual
Estimated: 2-3 hours
Actual: ~2 hours
Status: ✅ ON TARGET!

**Root Cause:**
When a library wasn't registered in sym-lib-table, the tool returned:
- success: true
- symbols: []
- count: 0
This was confusing because it looked like the library existed but was empty.
**The Fix:**
Now explicitly checks if library exists in sym-lib-table before attempting
to list symbols. If not found, returns:
- success: false
- Clear error message: "Library 'X' not found in sym-lib-table"
- Helpful details about how to resolve (add to sym-lib-table or use available libs)
- Count of available libraries
- Suggestion to use 'list_symbol_libraries' tool
**Test Results:**
✓ Non-existent library (BQ25896RTWT): Returns error as expected
✓ Valid library (Device): Returns 533 symbols successfully
**User Impact:**
Users will now get clear feedback when they try to access libraries that
aren't registered in their KiCad configuration, instead of seeing "0 symbols"
which suggests the library exists but is empty.
