Available tools 2

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

stock

get_stock_metric

Answer one financial metric for a US public company, spoken as a single natural-language sentence grounded in that company's most recent SEC 10-K filing (via EDGAR's XBRL data) -- not a guess. Use for a specific spoken question like "what's Tesla's revenue" or "what's Apple's earnings per share". Metric must be one of: revenue, eps, book_value_per_share, market_cap, total_assets, total_liabilities, price.

get_stock_snapshot

Give a short spoken financial snapshot of a US public company (revenue, earnings per share, market cap, book value per share) grounded in its most recent SEC 10-K filing. Use for a broad spoken question like "tell me about Apple's financials" rather than one specific figure.

Voicebrief — questions

Answers built from our own checks of this server.

What can Voicebrief do?

It exposes 2 tools, read directly from the server on our last check. Among them: get_stock_metric, get_stock_snapshot. 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 Voicebrief working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 38 of 92 checks got a reply (41.3%), average response time 533 ms. The bar chart above shows every period we have measured.

The registry lists Voicebrief as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Voicebrief?

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

Does Voicebrief need an API key?

No. Voicebrief completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Voicebrief?

It answers our handshake in 533 ms on average, which is faster than 29% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
