Add Computer Use API support for Anthropic Claude#36
Merged
Conversation
Ensures required Computer Use headers are sent to Anthropic's API: - anthropic-version: 2023-06-01 (required by Anthropic API) - anthropic-beta: computer-use-2025-01-24 (enables Computer Use tools) Without these headers, Anthropic's API does not enable browser automation tools (screenshot, mouse, keyboard), causing Computer Use tasks to fail. Tested and confirmed working with Claude Max authentication.

Summary
This PR ensures required Computer Use API headers are sent to Anthropic's API, enabling browser automation features.
Problem
CCProxy currently does not ensure that Computer Use headers reach Anthropic's API. Without these headers, Anthropic's API does not enable browser automation tools (screenshot, mouse control, keyboard input), causing Computer Use tasks to fail.
Solution
Add explicit header setting in
ccproxy/plugins/claude_api/adapter.pyto ensure these required headers are always sent:Why These Headers Are Required
anthropic-version: 2023-06-01Required header for all Anthropic API requests. From the official documentation:
anthropic-beta: computer-use-2025-01-24Enables Computer Use beta feature. From the Computer Use documentation:
Without this header, the API treats requests as normal chat without enabling the
computer_20250124tool.Testing
Tested with Claude Max authentication on browser automation tasks:
Before: Tasks requiring Computer Use tools failed
After: Tasks succeed (identical behavior to direct Anthropic API usage)
Changes
ccproxy/plugins/claude_api/adapter.py(5 lines added)Impact
This enables CCProxy users to access Anthropic's official Computer Use capabilities without requiring direct API access. Particularly valuable for:
Note: This is a minimal change (5 lines) that enables an official Anthropic API feature. The headers are documented requirements per Anthropic's official API documentation.
