kicad-skip's write() serializes from original parsed data, silently
discarding in-memory _elements mutations. Switch to the same sexpdata
approach used by add_wire: parse, find matching wire, delete the entry,
write back. Also adds WireManager.delete_wire() static method.

ElementCollection in kicad-skip doesn't implement remove(), causing
'WireCollection object has no attribute remove' errors. Access the
underlying _elements list directly for wire, label, and symbol deletion.

Exports schematic to SVG via kicad-cli, then converts to PNG using
cairosvg (same approach as get_board_2d_view). Falls back gracefully
to SVG if cairosvg is not installed. Supports configurable output
size and format (png/svg).

Add all missing schematic operations identified in the gap analysis:
Inspection (P0/P2):
- list_schematic_components: enumerate all components with refs, values, pins
- list_schematic_nets: list all nets with their connections
- list_schematic_wires: list all wire geometry
- list_schematic_labels: list net labels, global labels, power flags
Editing (P0/P1):
- annotate_schematic: assign ref designators to unannotated components (R? → R1)
- move_schematic_component: reposition placed symbols
- rotate_schematic_component: rotate/mirror placed symbols
- delete_schematic_wire: remove wires by coordinates
- delete_schematic_net_label: remove labels by name/position
Export (P1):
- export_schematic_svg: schematic SVG export via kicad-cli
- export_schematic_pdf: enhanced with file path return & blackAndWhite support
Also registers list_schematic_components and annotate_schematic as
direct tools (always visible) since they're prerequisites for
reference-based workflows.

save_project uses project_commands.board, which was NOT in the propagation
list after pcbnew.LoadBoard() in _handle_import_svg_logo. As a result,
save_project() wrote the old in-memory board (without logo gr_poly entries)
back to disk, erasing the logo every time.
Fix: call _update_command_handlers() after reload, which updates all
command handler board references including project_commands.
Claude sends {shape:'rectangle', params:{x,y,width,height,...}} but handlers
were reading params.get('width') on the outer dict → None → wrong board size.
outline.py: extract inner = params.get('params', params) at method start,
read all dimensions from inner dict.
kicad_interface.py (_ipc_add_board_outline): delegate 'rectangle' to SWIG
path (same as 'rounded_rectangle') so Claude's shape+dims call is handled
correctly. For polygon IPC path: also unwrap inner params for points/width.
create_component_instance used line-based insertion which placed new
symbols BEFORE (kicad_sch ...) header when the file was written as
a single line by sexpdata.dumps(). Switch to rfind()-based string
insertion which is format-independent.
Also remove StreamHandler(sys.stdout) from logging — Python logs now
go only to file (~/.kicad-mcp/logs/kicad_interface.log) to avoid
polluting MCP stderr with INFO/DEBUG entries shown as [error].
- add_schematic_net_label: warn in description that coords must be exact pin endpoints; recommend connect_to_net instead
- connect_to_net: stub wire direction now follows pin angle (was hardcoded +X)
- pin_locator.py: add get_pin_angle() and _get_lib_id() helpers
- new tool: get_schematic_pin_locations(schematicPath, reference) → returns exact x/y of every pin endpoint, so Claude can place labels correctly
The previous line-based parser (split("\n") + line-by-line regex)
failed when the MCP server itself generates .kicad_sch files as a
single line. The new implementation works directly on the raw content
string using parenthesis-depth matching to find symbol blocks,
making it independent of formatting/whitespace.
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
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
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).

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!
