Gauge is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.
What it does
Verify official facts with Bitcoin-anchored proof. 180+ signals, x402 pay-per-call.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http changchinfu-gauge-mcp https://api.truthbear.co/mcp
# 2 — ask your agent for something these tools do
# verify_citation, find_signal, get_official_record and 2 more
Gauge costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http changchinfu-gauge-mcp https://api.truthbear.co/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
5 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
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.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| record_hash | string | yes | sha256:<64 hex>, or a >=8-hex prefix as posted publicly |
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.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| industry | string | no | restrict to one domain, e.g. hydrology, agriculture, energy |
| signal_id | string | no | e.g. hydrology.river-level |
| entity | string | no | object id, e.g. a USGS site id |
| full | boolean | no | true = per-entity detail (larger); default compact summary |
Returns the REAL x402 payment challenge (accepts[]: network / asset / payTo / amount) for the paid endpoint that serves a given signal_id+entity, or any listed endpoint addressed directly by path. 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
| Parameter | Type | Required | Notes |
|---|---|---|---|
| path | string | no | Alternative addressing: any listed endpoint path, optionally with its query string (e.g. "/gauge/chokepoint-region?loc=hormuz"). The full list of legal paths is the free /manifest?all=1. Use this for |
| signal_id | string | no | which signal line, e.g. hydrology.river-level - use find_signal to list them |
| entity | string | no | which object within that line, e.g. the USGS site id 07010000 |
| dim | string | no | which product: full read (gauge) or a single add-on; the price of each is in the 402 challenge this tool returns, never here |
FREE. Ask how to pay for a listed endpoint and get every channel with its REAL status - including the ones that are wired but not open yet. Three channels exist: x402 micropayment (for an agent with a funded USDC wallet on Base), a stateless subscription Bearer token (for a person or team - no wallet, no private key, no account), and a card rail. This tool takes no payment and holds no key; it onl
| Parameter | Type | Required | Notes |
|---|---|---|---|
| path | string | no | A listed endpoint path (e.g. "/gauge/grid-reliability-region") to get its price alongside the channels. Omit it to get the channel list on its own. The full list of legal paths is the free /manifest?a |
FREE. Cross-verify one GAUGE interweave line: it returns each official series ("leg") in the line with its own record_hash, current/previous values, expected direction and per-leg minMove deadband, plus a count-style state (directions_matched / direction_mismatch / inverse_consistent / not_comparable / insufficient) and N-of-M. Everything needed to recompute the verdict OFFLINE is in the response
| Parameter | Type | Required | Notes |
|---|---|---|---|
| line | string | yes | which interweave line, e.g. "E" (state vs national unemployment) or "F" (drought vs crop). Public demo lines are E and F. |
| entity | string | yes | the object within the line, as US-<ST>, e.g. "US-TX" (case-insensitive). Required. |
- Every tool — any call limit is its publisher’s, not ours
- No card, and mcprush charges nothing for it
- Runs at its publisher’s own address — this marketplace is not in the path
- Nothing to cap, because mcprush bills nothing
What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |

Nothing here is billable: mcprush charges nothing to install Gauge or to call it, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither: the repository linked on this page is where this record was collected from, not a copy of what the address serves, so it is not graded in its place. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.0.5.
No release note was published with this version.
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Any signed-in account that does not publish Gauge can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
