An MCP server for Perigee, the open-source 3D viewer of the artificial objects orbiting the Earth, the Moon and Mars and of the spacecraft crossing the solar system. It lets an AI assistant (a teaching assistant, for example) answer questions such as “how far is Mars from the Earth on 1 December 2026?”, “where is the ISS now?” or “what is Lucy's mission?”, and hand the student a live 3D view, with how each number was obtained, from which data, how fresh and how accurate.
Validate Mermaid syntax and get error details your coding agent can use to correct a diagram. Check the source again before adding it to your documentation. Validation works without saving a diagram. Render SVG, PNG, or PDF, save diagrams privately, and publish selected snapshots. Your existing agent writes and corrects the source; MermaidDesk checks and renders it. Validation checks syntax, not whether a diagram accurately describes a system. Connect through MCP with Streamable HTTP and a scoped bearer API key. Enable MERMAID_RENDER for validation and rendering. A REST API is also available. MCP setup: https://www.mermaiddesk.com/developers/mcp REST API guide: https://www.mermaiddesk.com/developers/api
