What changed 18

Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 22 October 2026. No other catalogue keeps this.

22 Oct 5 tools changed the parameters they ask for10 times that day fetch_bulk_metrics, fetch_metric, get_asset_metrics and 2 more

22 Oct 4 tool descriptions were rewritten8 times that day fetch_metric, get_asset_metrics, get_assets_list and 1 more

and 9 more, back to 22 October 2026

Nothing serious here today

Today is the operative word: we check CryptoKeyhole every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

metric

End is exclusive. Metric-specific interval and retained-publication restrictions apply. No new observation is acquired.

get_metric_metadata

Read the current metric definition, supported intervals, method, coverage and source limitations.

asset

get_asset_metrics

Discover the available and held metrics of one asset: BTC, ETH, SOL, XRP, TRX, BNB, DOGE, TON, LINK, HYPE, WBTC, ADA, NEAR, XLM, BCH, LTC, UNI, AVAX, SUI, HBAR, WLD, WLFI, LIT, MNT, SHIB, QNT, ENA, MORPHO, AAVE, ONDO, DOT, ZRO, PEPE, SKY, ARB, FF, POL, APT, CRV, ZAMA, SENT, ETHFI, PENDLE, ENS, FET, LDO, EIGEN, SPX, EDGE, IMX, AXS, BAT, GRT, SYRUP, FLOKI, COMP, SAND, APE, PROM, ALT, GALA, NIL or ERA.

CryptoKeyhole — questions

Answers built from our own checks of this server.

What can CryptoKeyhole do?

It exposes 6 tools, read directly from the server on our last check. Among them: fetch_bulk_metrics, fetch_metric, get_asset_metrics, get_assets_list, get_metric_metadata, get_metrics_list. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is CryptoKeyhole working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 371 ms. The bar chart above shows every period we have measured.

How do I connect CryptoKeyhole?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does CryptoKeyhole need an API key?

No. CryptoKeyhole completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is CryptoKeyhole?

It answers our handshake in 371 ms on average, which is faster than 40% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
