Adds three HTTP endpoints to the Designer app bridge so external apps
(e.g. the Webflow Designer extension) can call MCP functionality over
HTTP instead of stdio:
- POST /api/tool-call — forwards { toolName, args } to the Designer
RPC bridge (same contract as the MCP tool call).
- GET /api/status — bridge health check.
- POST /api/upload-asset — uploads an image from a URL to the site
via the Webflow Data API. Uses a new shared uploadAssetFromUrl()
helper that the `upload_asset_from_url` MCP tool also calls.
initDesignerAppBridge now accepts an optional BridgeOptions { getClient }
so the upload endpoint can use the Data API without re-authenticating.
The tool-call and status endpoints work without getClient.

Summary
POST /api/tool-call,GET /api/status, andPOST /api/upload-assetHTTP endpoints on the Designer app bridge so external apps (e.g. the Webflow Designer extension) can call MCP functionality over HTTP instead of stdio.POST /api/upload-assettakes{ siteId, url, fileName?, altText? }and returns{ assetId, fileName, hostedUrl?, assetUrl? }. Built on a newuploadAssetFromUrl()helper that the existingupload_asset_from_urlMCP tool now also calls — single source of truth.initDesignerAppBridge()now acceptsBridgeOptions { getClient? }so the upload endpoint can use the Data API./api/tool-calland/api/statuswork withoutgetClient.Why
The campaign-agent extension was calling
http://localhost:1338/api/tool-callagainst a locally-patched bridge; the endpoints were never upstreamed. This PR ports them to the branch everyone on the hackathon is running.Test plan
