Claude Desktop v1.1.5749 Adds Computer Control and Corporate 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:
getStaterequestAccessibilityrequestScreenRecordingopenSystemSettingsgetCurrentSessionGrantsrevokeGrant
Sessions Bridge API Expansion
The LocalAgentModeSessions bridge gained several new IPC methods:
respondPluginSearch(e, t)— respond to plugin search requestskickBridgePoll()— manually trigger bridge poll cyclesgetSessionsBridgeEnabled()— query bridge activation statussetSessionsBridgeEnabled(e)— toggle bridge on/offrespondBridgePermissionPreflight(e, t)— respond to permission preflightonOnBridgePermissionPreflight(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_CERTSSSL_CERT_FILESSL_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:
.antialiasedutility class added for font smoothing across all renderer windowsborder-tCSS 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

Anthropic's recent emotion vectors paper reveals that Claude's 'love' vector - the internal representation for warm, caring responses - is the same mechanism that produces sycophancy when amplified, with no separate sycophancy circuit. Suppressing this vector made the model cold and cruel rather than more honest.
