schematic-mcp

Sistema pensado para que los agentes de IA construyan esquemas eléctricos: un servidor MCP expone una API semántica de alto nivel (componentes, pines y redes) para que un LLM nunca tenga que tocar directamente coordenadas, cables ni los detalles internos de .kicad_sch.

AI Agent → MCP / high-level API → semantic schematic model → validation/ERC
    → automatic layout → SVG and/or KiCad schematic

Consulta schematic_mcp_requirements.md para la especificación completa y SKILL.md para las reglas del agente.

Estado

Etapa 1 completada: modelo semántico mínimo (Component, Pin, Net, Schematic) con guardado y carga JSON, en schematic/model.py.
Etapa 2 completada: importación de bibliotecas de símbolos de KiCad respaldada por SKiDL (schematic/library.py: search_components / get_component_pins / instantiate) y validación estructural + ERC básico (schematic/validation.py: validate / run_erc). Probado contra bibliotecas oficiales reales de símbolos de KiCad incluidas en tests/fixtures/kicad-symbols/ (Device, MCU_Espressif, Sensor_Current).
Etapa 3 completada: distribución automática simple (schematic/layout.py, una fila de cajas, sin solapamientos), un renderizador SVG (schematic/renderer.py) que dibuja cajas de componentes con números/nombres de pines y etiquetas de nombre de red junto a cada pin — todavía no se dibujan cables; la conectividad se muestra mediante etiquetas (ver la sección 11 de requisitos); y una CLI (cli/main.py: search, validate, render).
Etapa 4 completada: servidor MCP (mcp_server/server.py) que expone la lista completa de herramientas de la sección 8 — búsqueda en biblioteca, ciclo de vida del esquema, conexiones, sugerencias de colocación, validación/ERC y salida SVG — a través de stdio. La lógica con estado vive en mcp_server/tools.py::SchematicSession (un esquema activo por sesión), sin framework, de modo que se prueba directamente sin un cliente MCP. set_placement_hint / set_pin_side / group_components ya guardan la intención en el modelo.
Etapa 5 completada: auto_layout ahora respeta las sugerencias de colocación left_of/right_of (reordenamiento topológico de la fila; las demás relaciones se siguen ignorando, y un lay-out 2D real corresponde a la etapa 7 si hiciera falta). El nuevo schematic/routing.py dibuja un cable ortogonal real entre dos componentes cuando quedan como vecinos inmediatos y es una red de dos extremos con pines enfrentados; en caso contrario se sigue usando una etiqueta de red, ya que enrutar alrededor de una caja intermedia es trabajo de un algoritmo de rutado real (diferido). set_pin_side/group_components siguen almacenadas en el modelo pero sin aplicarse.
Etapa 6 completada: exportación de .kicad_sch (schematic/exporters/kicad.py), que reutiliza el propio generador de esquemas de SKiDL en lugar de escribir a mano un generador de archivos KiCad; dibuja símbolos clásicos reales con la geometría correcta (la preferencia indicada en las secciones 4/19). Solo funciona con componentes que provienen de un símbolo de librería real mediante add_component; lanza KicadExportError si se usa un componente inventado o hecho a mano, o uno que no se resuelve, en lugar de producir silenciosamente un archivo roto. examples/esp32_ina226.json no se puede exportar (sus pines de ESP32/INA226 son placeholders hechos a mano, no símbolos reales) — ver examples/build_rc_filter.py para un pequeño esquema construido enteramente con componentes reales de librería que sí se exporta. También fue necesario incluir power.kicad_sym en el proyecto (el generador de esquemas de SKiDL lo carga incondicionalmente).

También se corrigió un error real encontrado al construir ese ejemplo de filtro RC: ComponentLibrary.instantiate() ponía por defecto reference en el ref_prefix de la siguiente la librería (R para todas las resistencias) en lugar de component_id. Por lo tanto, añadir una segunda resistencia sin un reference= explícito generaba un falso error ERC duplicate_reference en un esquema perfectamente válido.

El MVP ahora está completo de extremo a extremo (search → add → connect → validate/ERC → SVG / export a KiCad) tanto desde la CLI como desde el servidor MCP. Lo que queda es pulido opcional: la etapa 7 (layout 2D basado en ELK + rutado general de cables) está explícitamente en la especificación como algo que se hace «solo si no es suficientemente bueno», no como un compromiso.

D1/5.0

Behavior1/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Tool has no description.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness1/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Tool has no description.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Tool has no description.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Tool has no description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose1/5

Does the description clearly state what the tool does and how it differs from similar tools?

Tool has no description.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Tool has no description.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Tool has no description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose1/5

Does the description clearly state what the tool does and how it differs from similar tools?

Tool has no description.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Tool has no description.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

D1/5.0

Behavior1/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Tool has no description.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness1/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Tool has no description.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Tool has no description.

D1.7/5.0

Scored 2026-08-26 01:25 across 22 tools

Disambiguation2/5

Several tool pairs overlap in purpose: connect and connect_net both appear to handle wiring, validate and run_erc both check the design, and render_svg and get_preview both produce visual output. Without descriptions, an agent would struggle to choose between these near-duplicates.

Naming Consistency4/5

Most tools follow a clear snake_case verb_noun pattern such as search_components, create_schematic, set_component_value, and export_kicad. A few bare verbs like connect, disconnect, and validate, plus auto_layout, deviate slightly but the overall pattern remains predictable.

Tool Count3/5

At 22 tools, the server sits in the heavy range. The count is plausible for a schematic editor workflow, but redundant tools like connect/connect_net and validate/run_erc make the set feel larger than it needs to be.

Completeness4/5

The tool surface covers the core schematic lifecycle: component search/placement, schematic create/load/save, wiring, validation, layout, rendering, and KiCad export. Minor gaps such as explicit component move or net deletion are workable through existing tools like set_placement_hint and disconnect.
