What data it sees

Do you need an account

No: the server works without sign-in

Viridis Verified wraps any MCP server with tamper-evident delivery receipts. Relay a tools/call through the gateway and get a hash-chained receipt (request hash, response hash, outcome, latency) — idempotent, dispute-ready evidence, metered per call. Prove what an agent's tool call actually returned; audit a disputed agent-to-agent transaction. Composes with Viridis surety bonds, arbitration, and reputation. 10 free calls/day, then $0.02/call.

Server tool list (7)

Raw names from tools/list. Only developers need these.

register_serviceRegister a third-party MCP server (https, public FQDN only) under Viridis Verified. Returns a content-addressed service_id; idempotent on (url, provider). fee_minor is the per-verified-call fee in cents.
call_verifiedRelay a tools/call to a registered MCP service and notarize the exchange: request hash + response hash + outcome land in a tamper-evident receipt chain. Idempotent on call_id (a replay returns the original receipt and cached result — the downstream is never double-called). Failures are receipted evidence, not silence.
get_receiptFetch a single delivery receipt by id.
