Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “list_measurements”: Use when a claim about browser tools, capture quality, OCR recall or citation extraction needs a number behind it — or when you want to chec.”
“Use “get_measurement_data”: Use before quoting a figure: this returns what stands behind it — the values, the control run, and the conditions that limit them. Cite the.”
“Use “get_method”: Fetch a reproducible method: reading a browser extension's permissions, measuring OCR recall with a control run, or choosing between print-t.”
“Use “extract_citation”: Read the citation details a web page declares about itself and return them as a structured record plus ready-to-import RIS and BibTeX. Cover.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Proving Lab holds up.
Operated by Proving Lab (provinglab.dev) at its documented MCP endpoint — not a third-party mirror or community re-host.
This server only exposes public data — no account and no credentials are involved when you connect.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If Proving Lab adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose Proving Lab in the gate directory. No sign-in needed.
Proving Lab's tools are live in every AI client you've connected — with rules and logging built in.

https://provinglab.dev/mcpYes — Proving Lab operates its own remote MCP server at provinglab.dev. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
Add gate's gateway URL to your AI client once, then pick Proving Lab in the directory. No account or sign-in is needed. From then on, Proving Lab's tools are available in every client you've connected to gate.
No. Proving Lab runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
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.
Yes — you can get started with gate for free and connect Proving Lab in minutes. No credit card required.
Every server below works through the same gateway URL — connect once, add tools anytime.
