Visual MCP Builder

Visual MCP Builder

A visual editor for constructing MCP tool definitions and server manifests without writing JSON by hand. You add tools, set names and descriptions, and define parameters with types and defaults. The builder outputs valid JSON that you can paste into your config or commit to your repo.

When to use

Use the Visual Builder when you’re prototyping a new tool from scratch, when you don’t have existing code to convert, or when you want to tweak generated definitions with a form instead of editing raw JSON.
