SafeMarkdownEditor MCP Server

Instructions

        Load and analyze a Markdown document from a file path.
        
        Args:
            document_path: Path to the Markdown file (supports absolute, relative, and ~ expansion)
            validation_level: Validation strictness - "STRICT", "NORMAL", or "PERMISSIVE"
        

Implementation Reference

• src/quantalogic_markdown_mcp/enhanced_mcp_server.py:24-48 (handler)

  Primary handler for the 'load_document' MCP tool in the enhanced server. Decorated with @self.mcp.tool() for automatic registration and schema inference. Loads document via processor, analyzes structure, and returns metadata including preview.

• src/quantalogic_markdown_mcp/mcp_server.py:38-73 (handler)

  Base handler for the 'load_document' MCP tool. Decorated with @self.mcp.tool() for registration. Performs validation level mapping, loads via processor, and returns structured response with document analysis.
