sygnl47_entities | Tracked entity gazetteer plus today's guard state ($0.25). RETURNS: every entity SYGNL/47 listens for with its disambiguation rules attached — a country only counts when a policy instrument is nearby, "intel" does not count next to "agency" Inputs: payment_signature |

sygnl47_events_archive | Verified POTUS statement events at T+24h and older ($0.10). RETURNS: the full historical record, same complete schema as every other tier — the archive is not a sample and not a degraded copy. GUARANTEED MAX STALENESS: 86400 seconds. PRICE: Inputs: limit, since, payment_signature |
sygnl47_events_live | Verified POTUS statement events with no delay applied ($2.00). RETURNS: newest-first list of CONFIRMED observations, same schema as every other tier: verification block (live vs replay via acoustic fingerprinting, independent source count) Inputs: limit, since, payment_signature |

sygnl47_subscribe_live_30d | Buy a 30-day unmetered pass to the SYGNL/47 live tier ($750.00). Same contract as the 24-hour pass over a 30-day window: signed bearer token, unmetered access to the live tier, no widening of freshness beyond that tier, stateless verificati Inputs: payment_signature |
sygnl47_subscription_plans | FREE: prepaid-pass plans for SYGNL/47 (the subscription catalog). x402 is per-call by design. A subscription here is a PREPAID TIME-BOXED PASS on the same rails: one payment buys unmetered access to one tier for one window and returns a sig |

Deterministic ALLOW / REDUCE / REQUIRE_CONFIRMATION / BLOCK with reason codes, an order-hash-bound approved size, 60s expiry, and an EIP-191-signed attestation.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://api.sygnliq.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
