PaddleOCR MCP not working with Claude Desktop

[takaji10]

When I try to OCR an image of some text, I get the error "Error calling tool 'pp_structurev3'" in Claude Desktop. I've installed the required dependencies and configured my Claude config file like so:

{ "mcpServers": { "PP-StructureV3": { "command": "uvx", "args": [ "--from", "paddleocr-mcp", "paddleocr_mcp" ], "env": { "PADDLEOCR_MCP_PIPELINE": "PP-StructureV3", "PADDLEOCR_MCP_PPOCR_SOURCE": "aistudio", "PADDLEOCR_MCP_SERVER_URL": "https://(my server URL)", "PADDLEOCR_MCP_AISTUDIO_ACCESS_TOKEN": "(my access token)" } } } }

What could be going wrong? Thank you for any help.
