Toolgraph checks MCP connections before they break

Field notes

The page describes a browser canvas that reads MCP tool definitions directly from servers and checks connections against their JSON Schemas before execution. Its advertised validator covers nested shapes, required fields, unions, references, enums, and numeric or string constraints. Graphs can be tested against live servers, then exported as TypeScript with Zod validators or Python with Pydantic models; the site says the resulting code has no Toolgraph runtime dependency.
