Key features
- The sentinel never asks the user to configure MCP servers of its own.
- mcp-sentinel moves the polling loop out of the agent and into the plugin runtime — 2 inference calls regardless of task duration.
- MCP config discovery is the harness's job — different hosts fetch it differently (OpenCode via client.config.get().data mcp.
- Installing the plugin is the whole setup — it discovers and reuses the MCP servers the harness already has, in whichever way that harness exposes them
- From the host's MCP config — OpenCode.
