Truth Bear - Official Government Data with Cryptographic Proof (GAUGE) mcp_server
Official-source signals for AI agents. Every record ships a record_hash (canonical sha256, recomputable offline) plus the official source and timestamp, so you can verify what you were told without trusting this server. Sources are official government records and named registries: US federal agencies (USGS, NOAA, NWS, EPA, SEC EDGAR, openFDA, EIA, BLS, FAA, US CBP, USTR, USITC, Federal Register) plus IMF PortWatch, UNFCCC and standards-body feeds. **Free tools (no payment, no API key, no account):** - `verify_citation` - check any Truth Bear record_hash and get a plain-language reverse lookup of exactly what that hash attests. Use it on a citation another agent handed you, before you rely on it. - `find_signal` - coverage and freshness manifest: which signal 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. **Paid records** are bought directly over x402 (USDC on Base or Solana). `get_official_record` returns the real 402 challenge (network / asset / payTo / amount) and you pay at that URL from your own wallet. This server never takes payment and never delivers paid data. **Honesty rules we hold ourselves to:** - Descriptive only - no advice, no forecasts, no adjudication. The reading is yours. - No data found means 422 no_charge - you are not billed for a miss. - Cryptographic provenance: every paid response carries an Ed25519-signed citation, so delivery is tamper-evident and auditable offline with no call back to us. - Freshness is computed at request time and disclosed per record, including when an upstream source is overdue.
