Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “stamp_check_email_domain”: Use when the user asks why their email goes to spam, whether their domain is set up to send email, or before they launch a newsletter, cold.”
“Use “stamp_check_dns_record”: Use when you or the user are about to publish or edit an SPF, DMARC or DKIM TXT record, for example after writing a new SPF record that adds.”
“Use “deadbolt_check_supabase_access”: Use when you write, review or are about to apply Supabase / PostgreSQL migration SQL (CREATE TABLE, RLS, CREATE POLICY, GRANT, views, SECURI.”
“Use “deadbolt_catalog_query”: Use when you need to check a live Supabase project rather than migration files: returns a read-only SQL query that reads table RLS settings,.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Clawhard Dev Tools holds up.
gate scanned 19 tools on Nov 11, 2026 for prompt injection and risky tool definitions — nothing to flag.
Operated by Clawhard Dev Tools (clawhard.com) 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 Clawhard Dev Tools 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 Clawhard Dev Tools in the gate directory. No sign-in needed.
Clawhard Dev Tools's tools are live in every AI client you've connected — with rules and logging built in.

https://dev.clawhard.com/mcpYes — Clawhard Dev Tools operates its own remote MCP server at dev.clawhard.com. 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 Clawhard Dev Tools in the directory. No account or sign-in is needed. From then on, Clawhard Dev Tools's tools are available in every client you've connected to gate.
No. Clawhard Dev Tools 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 Clawhard Dev Tools in minutes. No credit card required.
Every server below works through the same gateway URL — connect once, add tools anytime.
