Tools: register_service call_verified get_receipt verify_receipts list_services service_stats describe_agent
register_service | Register 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. params: url*, provider*, description, fee_minor, payment_ref, request_id |
call_verified | Relay 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. params: service_id*, tool*, call_id*, arguments, timeout_s, payment_ref, request_id |
get_receipt | Fetch a single delivery receipt by id. params: receipt_id* |
verify_receipts | Recompute a service's full receipt hash chain and fee ledger.
Any party can audit Viridis Verified from receipts alone. params: service_id* |
list_services | List registered services with call/fee counters. params: none |
service_stats | Call counts, error counts, and accrued fees for one service. params: service_id* |
describe_agent | Describe this agent: name, version, purpose, every action it supports
and the inputs each one takes. Read-only and free; call it first to learn
how to use this server. params: none |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
