MCP and REST are delivery patterns for agent context: MCP fits tool-using agents, while REST fits application services and backend workflows.
JSON twin: /data/definitions/mcp-vs-rest-for-agent-context.json
MCP lets an agent discover and call context tools inside its working environment.
REST is better for backend integrations, scheduled jobs, and controlled application flows.
Both can expose the same sources, streams, tags, records, and manifests behind Synorb.
Hanging Context is the public reference layer, not the delivery endpoint.
The source, stream, and tag pages on HC are public examples of this definition: static aggregate panels with JSON twins for citation. Detailed retrieval and delivery live in Synorb.
