Connect JSON to Types and your agent gets 1 tool, among them json_to_types. It answers at https://json-to-types.gumballtools.com/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 9 of 9 times since 5 September 2026; the last check, on 17 October 2026, succeeded.
Convert JSON samples into TypeScript interfaces and Zod schemas, with inference caveats.
Description as the publisher wrote it.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://json-to-types.gumballtools.com/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: com.gumballtools. Endpoint host: json-to-types.gumballtools.com. ARD identifier: urn:air:com.gumballtools:mcp:json-to-types.
First indexed 5 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
