Implementation Planning for Composition Lifecycle
Technical Architecture
MCP Tool Extensions
Add 3 new tools to existing server:
typescript// tools/composition-lifecycle.ts
export const compositionTools = [
{
name: "create-new-composition",
description: "Create a new composition in Composer",
inputSchema: { type: "object", properties: {} }
},
{
name: "edit-composition-metadata",
description: "Edit composition title and description",
inputSchema: {
type: "object",
properties: {
title: { type: "string" },
description: { type: "string" }
}
}
},
{
name: "save-composition",
description: "Save composition and return shareable URL",
inputSchema: { type: "object", properties: {} }
}
];
Browser Automation Layer
typescript// lib/browser-automation.ts
export class ComposerAutomation {
async createNewComposition(): Promise<void>
async openConfigurationMenu(): Promise<void>
async editMetadata(title: string, description?: string): Promise<void>
async saveComposition(): Promise<string> // Returns encoded URL
}
URL State Management
typescript// lib/url-codec.ts
export class CompositionCodec {
static decode(encodedUrl: string): CompositionState
static encode(state: CompositionState): string
static extractFromUrl(url: string): string
}
Implementation Sequence
Phase 1: Browser automation primitives
Phase 2: URL encoding/decoding utilities
Phase 3: MCP tool integration
Phase 4: End-to-end testing
