space-ocr-mcp
MCP (Model Context Protocol) server for space-ocr — structured OCR with verified per-character bounding boxes.
Why
Unlike calling Gemini/GPT-4V directly, space-ocr re-anchors LLM output to real Google Vision API symbols, so bounding boxes are not hallucinated. AI agents that act on the extracted data (auto-fill, verification UI, accounting reconciliation) can trust the coordinates.
Tools
ocr_extract— Extract structured fields from a document image. Passtemplate_idfor built-in document types orfieldsfor custom schemas.list_templates— List built-in document templates (receipt,invoice,purchase_order,delivery,quote,bankbook,resident_card,driver_license,passport).
Install & run
npx -y space-ocr-mcp
Set SPACE_OCR_API_KEY (issue one at space-ocr.com → Settings → API Keys).
