This server validates Mermaid diagram syntax and provides grammar checking via the Model Context Protocol (MCP).
Validate Mermaid diagrams: Submit any text to check whether it constitutes valid Mermaid diagram syntax.
Receive validation feedback: Returns an empty string if valid, or a descriptive error message explaining any syntax issues.
Integrate with MCP clients: Works with any MCP-compatible client (e.g., Cursor) via stdio or SSE transport.
Run as HTTP service: Optionally start with --http --port=4000 for SSE-based communication.
Easy to install: Available as an npm package (@bjmhe/mermaid-grammer-inspector-mcp), runnable via npx or installed globally.
