Clipboard images routed directly to model instead of MCP when model lacks vision support #18437
Description
Description
Problem
When a clipboard image is received and the current model does not support image input, opencode attempts to attach the image directly to the model and fails with:
ERROR: Cannot read "image.png" (this model does not support image input)
This happens before any agent code can intercept the image and route it to the minimax_search_understand_image MCP tool.
Expected Behavior
There should be a config option or automatic fallback to route clipboard images directly to the minimax_media MCP's minimax_search_understand_image tool instead of passing them to the language model.
Workaround (insufficient)
Adding AGENTS.md rules to intercept clipboard images doesn't help because opencode itself tries to attach the image to the model before agent code runs.
Suggested Fixes
- Add a config option like imageInput: "mcp" to route images to MCP when model lacks vision
- Add automatic MCP fallback when model doesn't support image attachments
- Provide a way to disable native image attachment handling

I encountered the same problem when using GLM-5, but I had deployed a separate NewAPI instance, forked it, and had NewAPI convert the incoming image into a URL. I also specified in AGENTS.MD that xxxMCP should be used for image understanding.
