What it does

Kroki MCP provides AI agents with the ability to generate complex diagrams from text. It connects to a Kroki backend (local or remote) to convert various textual representations—including PlantUML, Mermaid, and C4—into high-quality image files. This allows an LLM to architect systems or map flows and then output a visual artifact for the user.

Tools

convert_diagram: Converts a text-based diagram definition into a specified image format (PNG, SVG, JPEG, PDF).
