Jsoncanvas
A remote MCP server for creating, editing, and exporting JSON Canvas files, the open infinite-canvas format used by Obsidian. Exposes seven tools: create and validate canvases, batch-edit nodes and edges, export to markdown, SVG, PNG, or Mermaid diagrams, and search across all your stored canvases. Includes an inline interactive viewer for pan and zoom. Authentication is handled via Microsoft Entra OAuth through the MCPCentral gateway, with per-user storage isolation. Useful when you need to programmatically generate or manipulate canvas-based knowledge graphs, flowcharts, or spatial documents without opening Obsidian itself. PNG export runs through a hardened headless browser for full-fidelity raster output.
