PlayCanvas Editor MCP Server

Instructions

Implementation Reference

• src/tools/entity.ts:10-21 (registration)

  Registration of the MCP tool 'create_entities'. Includes inline input schema validation using Zod and a handler function that proxies the call to the WebSocket server via wss.call('entities:create', entities). This constitutes the full tool implementation in the MCP context.

      'create_entities',
      'Create one or more entities',
      {
          entities: z.array(z.object({
              entity: EntitySchema,
              parent: EntityIdSchema.optional().describe('The parent entity to create the entity under. If not provided, the root entity will be used.')
          })).nonempty().describe('Array of entity hierarchies to create.')
      },
      ({ entities }) => {
          return wss.call('entities:create', entities);
      }
  );

• src/tools/entity.ts:18-20 (handler)

  The handler function for the 'create_entities' tool, which receives the validated 'entities' input and forwards it to the backend via wss.call('entities:create', entities).

  ({ entities }) => {
      return wss.call('entities:create', entities);
  }

• src/tools/entity.ts:13-16 (schema)

  Input schema for 'create_entities' tool using Zod: non-empty array of objects with 'entity' (EntitySchema) and optional 'parent' (EntityIdSchema).

  entities: z.array(z.object({
      entity: EntitySchema,
      parent: EntityIdSchema.optional().describe('The parent entity to create the entity under. If not provided, the root entity will be used.')
  })).nonempty().describe('Array of entity hierarchies to create.')
