 "title": "Combine a vision model with local OCR for exact clicks",
 "page_title": "How to combine a vision model with local OCR for exact clicks with Nuphus MCP",
 "summary": "Use your own vision model for meaning and local OCR for pixel-precise coordinates on screen.",
 "who": "A developer or analyst whose agent must find a labeled control on screen and click it reliably.",
 "problem": "A vision model can describe a screen but often cannot give exact coordinates for a click.",
 "outcome": "The agent gets a semantic description from the vision model and exact coordinates from OCR, then clicks and checks the result.",
 "steps": [
  "Set `NUPHUS_MCP_VISION_API_KEY` and `NUPHUS_MCP_VISION_MODEL` in the MCP client env, and `NUPHUS_MCP_VISION_BASE_URL` if you use a non-default endpoint.",
  "Call `desktop_vision` with a screenshot and a question about the screen.",
  "Call `desktop_perceive` to get local OCR text and coordinates; models download on first run.",
  "Use the returned coordinates with the mouse click tool, then take a screenshot to verify."
 ],
 "agent_prompt": "Use the nuphus-mcp desktop_vision tool to describe where the <target label> button is on screen, then use desktop_perceive to find its exact coordinates. Click it and return a screenshot path. Verify the screenshot shows the expected change before you report success.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "45 minutes",
 "basis": "readme",
 "caveat": "desktop_vision returns a clear error when it is not configured, and the README notes Zhipu GLM-4V-Flash caps output at 1024 tokens, so text-heavy screens may need a higher NUPHUS_MCP_VISION_MAX_TOKENS.",
