Vaults Diagram Tools

malnati/vaults-diagram-tools

Exposes three MCP tools for generating and rendering Mermaid diagrams: render_mermaid_text and render_mermaid_file produce SVG and JPEG assets with manifests, while generate_source_diagrams maps your actual source code structure into diagram form. Reach for this when you want agents to visualize architecture or generate documentation diagrams without manual Mermaid authoring. The underlying toolkit also ships as an npm package, GitHub Action, and container image, so you can run the same rendering logic in CI pipelines or local builds. It's extracted from a larger Vaults toolchain but strips out content management, leaving just the diagram generation surface. Works over stdio transport and already listed in the MCP Registry at version 0.1.4.
