Check breach exposure for your verified email and check locally computed password hash prefixes. Connect the official LeakData MCP server to Claude, ChatGPT, or Cursor through gate — one gateway URL, no config files, security-checked.
Free to start · No credit card · No hosting needed
Pick your client. Copy, paste, done — or let gate handle sign-ins and policies for you.

Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “leakdata.search”: Use this when the linked LeakData user asks to check their verified primary email. For a current check, call this tool and report only its r.”
“Use “leakdata.password_prefix_check”: Call this only when the current user message supplies a locally computed five-character SHA-1 hash prefix and asks to check it. Never invent.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how LeakData holds up.
gate scanned 2 tools on Oct 13, 2026. A few things are worth a look before you connect.
Operated by LeakData (leakdata.io) 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 LeakData 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 LeakData in the gate directory. No sign-in needed.
LeakData's tools are live in every AI client you've connected — with rules and logging built in.

Fetched live from the official endpoint and re-checked daily by gate — not marketing copy.
leakdata.search — Use this when the linked LeakData user asks to check their verified primary email. For a current check, call this tool and report only its r
leakdata.password_prefix_check — Call this only when the current user message supplies a locally computed five-character SHA-1 hash prefix and asks to check it. Never invent
https://leakdata.io/mcpYes — LeakData operates its own remote MCP server at leakdata.io. 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 LeakData in the directory. No account or sign-in is needed. From then on, LeakData's tools are available in every client you've connected to gate.
No. LeakData 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 LeakData in minutes. No credit card required.
Every server below works through the same gateway URL — connect once, add tools anytime.
