What you can do

What your AI can do with 3TG Test Generation

Real prompts you can type the moment it's connected — no setup, no docs to read.

“Use “create_tests”: Generate Jest/Vitest tests for the exported functions and React components in a TypeScript source file. Use this whenever the user asks for.”

“Use “create_spec”: Generate a functional-requirements spec (`.3tg.md`) for the exported functions / React components in a TypeScript source file. This is "Flow.”

“Use “create_tests_from_spec”: Compile a hand-edited functional-requirements spec (`.3tg.md`) into actual Jest/Vitest tests. This is "Flow B" — the user has already author.”

“Use “create_spec_for_function”: Generate a functional-requirements spec (`.3tg.md`) scoped to a single exported function or React component. Same shape as `create_spec` but.”

Security check

How secure is the 3TG Test Generation MCP server?

Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how 3TG Test Generation holds up.

✓ Verified directory server3TG Test Generation · 3tg.dev

Official endpoint

Operated by 3TG Test Generation (3tg.dev) 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 3TG Test Generation adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

FAQ

Questions, answered

Is there an official 3TG Test Generation MCP server?

Yes — 3TG Test Generation operates its own remote MCP server at mcp.3tg.dev. 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 3TG Test Generation to Claude or ChatGPT?

Add gate's gateway URL to your AI client once, then pick 3TG Test Generation in the directory. No account or sign-in is needed. From then on, 3TG Test Generation's tools are available in every client you've connected to gate.

Do I need to host anything?

No. 3TG Test Generation runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.

Is the 3TG Test Generation 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.
