What your AI can do with JSON to Types
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “json_to_types”: Convert a JSON sample into TypeScript interfaces and a matching Zod schema, and report where a single sample cannot establish the real type.”
How secure is the JSON to Types MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how JSON to Types holds up.
Official endpoint
Operated by JSON to Types (gumballtools.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If JSON to Types adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Pick JSON to Types
Choose JSON to Types in the gate directory. No sign-in needed.
Use it anywhere
JSON to Types's tools are live in every AI client you've connected — with rules and logging built in.

Who runs the JSON to Types MCP server?
The JSON to Types MCP server at a glance
https://json-to-types.gumballtools.com/api/mcpQuestions, answered
Is there an official JSON to Types MCP server?
Yes — JSON to Types operates its own remote MCP server at json-to-types.gumballtools.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect JSON to Types to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick JSON to Types in the directory. No account or sign-in is needed. From then on, JSON to Types's tools are available in every client you've connected to gate.
Do I need to host anything?
No. JSON to Types runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the JSON to Types MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect JSON to Types in minutes. No credit card required.
