Security check

How secure is the D Fetcher MCP server?

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

✓ Verified directory serverD Fetcher · dfetcher.com

Official endpoint

Operated by D Fetcher (dfetcher.com) 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 D Fetcher 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 D Fetcher MCP server?

Yes — D Fetcher operates its own remote MCP server at dfetcher.com. 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 D Fetcher to Claude or ChatGPT?

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

Do I need to host anything?

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

Is the D Fetcher 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.
