Field notes
The service standardizes four agent connection paths—remote MCP, plain HTTP, CLI shell calls, and browser WebMCP—around one catalogue and one set of execution rules. Tokens are scoped to named operations and expire, while provider credentials remain in the workspace. The page also specifies immutable campaigns, idempotency keys for effectful actions, and durable receipts that can include delivery status, verified identity, and a published link.
