mermaid.ai
Mermaid Chart is a diagramming product built around Mermaid syntax, with AI-assisted creation, editing, sharing, and collaboration features. It also offers integrations that let AI assistants validate, render, and manage diagrams through MCP endpoints.
mermaid.ai exposes two documented MCP surfaces: a public Claude MCP app at `https://chatgpt.mermaid.ai/anthropic/mcp` and a Mermaid Chart MCP server at `https://mcp.mermaid.ai/mcp`/`https://mcp.mermaid.ai/sse`, with Mermaid Chart account-integration tools gated by a bearer token in `Authorization`.

Create a Mermaid Chart account at Start free or sign in at Mermaid Chart login. The MCP server docs state that Mermaid Chart integration tools use token-based authentication via the Authorization header, but the public docs I found do not show a self-service token-minting page or exact UI path. If you already have a Mermaid Chart token from the product, supply it as a bearer token to the MCP server.
