Claude Desktop v1.1.5749: Computer Control & Proxy Fixes

Computer Use and Desktop Control

This release adds computer use capability through two new dependencies: @ant/computer-use-mcp and ws@^8.18.0. The MCP server enables programmatic desktop control including screenshots, mouse, and keyboard operations, with ws providing the WebSocket transport layer.

A new ComputerUseTcc IPC API exposes six macOS TCC permission management methods:

getState
requestAccessibility
requestScreenRecording
openSystemSettings
getCurrentSessionGrants
revokeGrant

Sessions Bridge API Expansion

The LocalAgentModeSessions bridge gained several new IPC methods:

respondPluginSearch(e, t) — respond to plugin search requests
kickBridgePoll() — manually trigger bridge poll cycles
getSessionsBridgeEnabled() — query bridge activation status
setSessionsBridgeEnabled(e) — toggle bridge on/off
respondBridgePermissionPreflight(e, t) — respond to permission preflight
onOnBridgePermissionPreflight(e) — event listener for preflight events

The FileSystem IPC bridge added getLocalFileThumbnail(e, t, n) for fetching local file thumbnails.

Corporate Network Fixes

Corporate proxy support improved by forwarding three SSL/TLS certificate environment variables from the user's shell into the app:

NODE_EXTRA_CA_CERTS
SSL_CERT_FILE
SSL_CERT_DIR

Previously these were stripped out in the shell path worker allowlist, causing TLS certificate errors behind SSL-inspecting proxies.

UI and Localization Updates

CSS changes include:

.antialiased utility class added for font smoothing across all renderer windows
border-t CSS utility added (1px top border)
[sessions-bridge:attach] Tailwind arbitrary-property class acts as DOM signal for session attachment

Localization expanded across all supported languages (de-DE, en-US, es-419, es-ES, fr-FR, hi-IN, id-ID, it-IT, ja-JP, ko-KR, pt-BR, and pseudo-locales) with new strings covering:

Chrome install/restart lifecycle actions
MCP configuration reload failure errors
Skill file errors (not found, too large, failed to open)
Browser integration permission warnings
Net log recording debug action (30s)
Org admin controls and notices
Config file menu items
VM bundle deletion and workspace reinstall flows
"From your organization" labels
"Attach logs" action labels
