Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
Sillage makes buying signals available to agents through its API and a published MCP server. Assistants can configure workspaces, manage account lists, set up signal monitoring and retrieve detections or generated content. API v3 is publicly documented in beta, with workspace-scoped authentication. Published skills provide workflow instructions for assistants using the MCP tools, extending access from reading signals to operating the monitoring workflow.
