Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “ip_lookup”: Context lookup: Resolve an IPv4 or IPv6 address to its geolocation, ASN, org name, and city/country. Use when you need network or location c.”
“Use “dns_lookup”: Context lookup: Resolve a single DNS record type (A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, or SRV) and return the raw answers. Use for quick,.”
“Use “dossier_dns”: Core dossier check: Fetch a domain's full DNS profile — A, AAAA, NS, SOA, CAA, and TXT records — all in parallel. Use as the first step of a.”
“Use “dossier_mx”: Core dossier check: Look up a domain's MX (mail exchanger) records and return them sorted ascending by priority. Use when verifying inbound-.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how MCP holds up.
Operated by MCP (domainposture.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 MCP 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 MCP in the gate directory. No sign-in needed.
MCP's tools are live in every AI client you've connected — with rules and logging built in.

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