Tools
| Tool | Description | Behaviour |
|---|---|---|
| agent_lease_lock | Hosted distributed lease lock for agents: acquire/renew/release a named lock with a TTL and a monotonic fencing token so only one agent does a job at a time. Share state by namespace | Not declared |
| agent_spend_ledger | Hosted shared spend ledger for agents: set a budget ceiling, atomically reserve before paying (never overspends, even with many agents at once), then settle or release. Idempotent. Share state by namespace | Not declared |
| mcp_usage_metering | Record a metered usage event for any MCP tool call and return an invoice line preview (dry run) | Not declared |
