Available tools 3

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

official
get_official_record
Returns the REAL x402 payment challenge (accepts[]: network / asset / payTo / amount) for the paid endpoint that serves a given signal_id+entity. This tool does NOT deliver paid data and does NOT take payment - MCP has no payment layer. Pay at the returned url with your own x402 client (USDC on Base or Solana, gasless EIP-3009; pay from a plain EOA) and you receive the record directly, with record_hash you can verify offline. This tool only fetches the 402 challenge; it delivers no paid data and collects no payment.
signal
find_signal
FREE coverage + freshness manifest: which signal_id lines exist, how many entities each covers, and fresh/recent/stale counts - so you can check "is my entity covered and how fresh" BEFORE paying. Optional filters: industry, signal_id, entity.
verify
verify_citation
FREE. Given a record_hash from any Truth Bear record, look it up and recompute the canonical hash server-side, returning whether it is a genuine Truth Bear official record plus a plain-language reverse lookup of what exactly that hash attests. Use this to check a citation you were handed by another agent or document BEFORE relying on it. No payment, no API key.

MCP Gauge — questions

Answers built from our own checks of this server.

What can MCP Gauge do?
It exposes 3 tools, read directly from the server on our last check. Among them: find_signal, get_official_record, verify_citation. 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 MCP Gauge working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 1896 ms. The bar chart above shows every period we have measured.
How do I connect MCP Gauge?
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 MCP Gauge need an API key?
No. MCP Gauge completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is MCP Gauge?
It answers our handshake in 1896 ms on average, which is faster than 1% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is MCP Gauge open source?
Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
