MCP server
Descripcion
agrupar diferentes nodos para reusarlos con IA
Notas
MCP server: son flujos de trabajo que se comportaran como un END point para exponer diferentes servicios
como por ejemplo los nodos de google (enviar,leer,consultar) etc y poder ser usada por una IA.
Caracteristicas de los MCP server:
1.Cada vez que se ejecute el MCP server se cobrar como la ejecucion de un flujo de trabaja asi que para entornos donde
cobran por cada ejecucion esto se debe tener en cuenta.
2. son flujos que se exponen como un servicio es decir tiene una URL para ser llamados
3. se puede usar estos servicio externamente hacia otras aplicaciones.
Pasos para crearlo
1. Crear un Flujo con el nombre "MVC - Gmail" el cual guardara herramientas de gmail
2. buscamos el nodo MCP Trigger. generara una URL muy parecida a un Webhook
3. en el trigger agregan todo las tools de gmail para (crear,enviar, crear borrador) ponerles nombres sin espacio ni
caracteres especiales.
4. publicar el MVC para que cualquier otro Flujo lo pueda usar.
5. crear otro flujo que tenga el nodo de Chat + Agente.
6. en el IA agente en tools se busca el nodo MCP server client
7. en el nuevo nodo. pegan la URL del MCP que se creo en el punto 4. y seleccionamos en "tools a incluir" damos todas
