Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “mcp_observatory_state”: What was measured, when, over what population, and what the measurement cannot tell you. Read this before quoting any number from this serve.”
“Use “mcp_observatory_summary”: The counts, as published and as corrected. How many addresses answered, how many tools they exposed, how many stated who compensates their o.”
“Use “mcp_observatory_lookup”: What happened when we contacted one address, or an aggregate for one host. Returns the record hash and the procedure to recompute it. There.”
“Use “mcp_observatory_disclosure_guide”: How the 152 servers that stated who compensates their operator actually did it - the field names observed in the wild, with counts. Not a sp.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how MCP Observatory: one read only walk over every https endpoint in the official registry holds up.
Operated by MCP Observatory: one read only walk over every https endpoint in the official registry (the-horizons-innovation.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 Observatory: one read only walk over every https endpoint in the official registry 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 Observatory: one read only walk over every https endpoint in the official registry in the gate directory. No sign-in needed.
MCP Observatory: one read only walk over every https endpoint in the official registry's tools are live in every AI client you've connected — with rules and logging built in.

https://observatory.horizonshield.dev/mcpYes — MCP Observatory: one read only walk over every https endpoint in the official registry operates its own remote MCP server at observatory.horizonshield.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 MCP Observatory: one read only walk over every https endpoint in the official registry in the directory. No account or sign-in is needed. From then on, MCP Observatory: one read only walk over every https endpoint in the official registry's tools are available in every client you've connected to gate.
No. MCP Observatory: one read only walk over every https endpoint in the official registry 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.
