fix(server): missing timeout on all requests.get() calls — potential indefinite hang

[alfonsodg]

Problem

Multiple requests.get() calls throughout server.py have no timeout parameter, which can cause the server to hang indefinitely if the remote server is unresponsive.

Exact locations

All in minimax_mcp/server.py:

1. voice_clone() — requests.get(file) for URL download (line ~175)
2. voice_clone() — requests.get(response_data.get("demo_audio")).content (line ~205)
3. play_audio() — requests.get(input_file_path).content (line ~220)
4. generate_video() — requests.get(download_url) for video download (line ~330)
5. query_video_generation() — requests.get(download_url) (line ~365)
6. text_to_image() — requests.get(image_url) for image download (line ~410)

Impact

• MCP server can hang indefinitely waiting for a response
• No way to recover without killing the process
• Blocks the entire MCP tool pipeline

Proposed solution

Add a module-level constant and apply to all requests.get() calls:

# At module level
DOWNLOAD_TIMEOUT = 120  # seconds

# Apply everywhere:
requests.get(url, timeout=DOWNLOAD_TIMEOUT)

Also consider adding stream=True for large downloads (video) to avoid loading entire file into memory.

Acceptance criteria

• Every requests.get() call has an explicit timeout parameter
• Large file downloads use streaming where appropriate
• Timeout errors are caught and reported to the user
