App Inventor MCP
App Inventor MCP
Un servidor MCP (Model Context Protocol) que permite a los agentes de IA creer y editar proyectos de MIT App Inventor. El agente crea archivos .aia reales en el disco, que te importas en App Inventor mediante Proyectos > Importar (.aia).
Forma parte de la famila AIA Stitch. Proyecto a.: aia-stitch (interfaz web para fusionar proyectos).
Por qué
App Inventor es una herramienta visual de arrastrar y soltar que, históricamente, ha dejado fuera a los agentes de IA. Pero un archivo .aia no es just un zip: las pantallas son documentos JSON (*.scm), los bloques son XML (*.bky), y las recursos son archivos planos. Este servidor expone el "esqueleto" de los hechos como herramientas que any cliente ent MCP can "invocar", de modo que un agente puede generar para ti una app completa con likely screens de antes of that "abras siquiera el diseñador".

| Añade una screen |
| Lista las pantallas, los components, los assets, y los properties |
| Lee los components, la properties and the XML de one block |
| Añade a component, optionally nested in one layout |
| Set a property in the screen or in a component |
| Reemplaza the block XML of a pc |
| Generate event handlers (when click do...) without know the block XML |

Pruebas
node test.mjs # library roundtrip: create, author, merge
node smoke.mjs # full MCP protocol handshake + tool calls over stdio
node stress.mjs # scale (25 screens / 120 components), concurrency, abuse, recoveryLímites honesto
Los components and adquiridos de las screen are fully compatible. La edición de bloques funciona a dos niveles: event handlers via aia_add_event_handlers (assigning properties and navigating between screens), or raw Blockly XML via aia_get_screen / aia_set_blocks. Aún no we have a high level of language for all block types. The UI-first gives full support today; the logic special can require some final touches inside Inventor.
All data operations are serialized by path within the process, so the requests chained/current from a agent are secure. The concurrent access of another process to the same .aia is not protected; don't edit one file from two servers.
