What your AI can do with CryptoKeyhole
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “get_assets_list”: List the active analytics assets, each with its code and name. Use a code as the asset argument of the other tools.”
“Use “get_metrics_list”: Discover metrics for one asset (BTC by default) by existing category, including honest held and delayed states. Cursor pages follow the curr.”
“Use “get_asset_metrics”: Discover the available and held metrics of one asset. Use it once you know the asset: asset is required, so the answer never falls back to B.”
“Use “get_metric_metadata”: Read the current metric definition, supported intervals, method, coverage and source limitations.”
How secure is the CryptoKeyhole MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how CryptoKeyhole holds up.
Security grade A
gate scanned 6 tools on Nov 1, 2026 for prompt injection and risky tool definitions — nothing to flag.
Official endpoint
Operated by CryptoKeyhole (cryptokeyhole.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 CryptoKeyhole adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

get_asset_metrics — Discover the available and held metrics of one asset. Use it once you know the asset: asset is required, so the answer never falls back to B
get_metric_metadata — Read the current metric definition, supported intervals, method, coverage and source limitations.
fetch_metric — Read exact unreduced observations of one metric with decimal strings, original source clocks, revision, finality and gaps. End is exclusive.
fetch_bulk_metrics — Read multiple metric selections sequentially. Each item retains its own provenance and revision; this is not one atomic snapshot. Unsupporte

https://cryptokeyhole.com/api/v1/mcpQuestions, answered
Is there an official CryptoKeyhole MCP server?
Yes — CryptoKeyhole operates its own remote MCP server at cryptokeyhole.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 CryptoKeyhole to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick CryptoKeyhole in the directory. No account or sign-in is needed. From then on, CryptoKeyhole's tools are available in every client you've connected to gate.

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