+description: >
+  SandBase Harness MCP bridge for managing agents and durable sessions through a
+  self-hosted Harness runtime. It exposes tools to list agents, create and run
+  sessions, inspect session state, list artifacts, and stop sessions. The bridge
+  communicates over stdio and connects to a running Harness API supplied by the
+  user; execution isolation depends on the selected backend and deployment
+  configuration.
