pub const MCP: &str = "mcp";Expand description
Unified MCP tool (action: search_tools | get_tool_details | list_servers |
connect | disconnect). connect/disconnect are config-gated lifecycle
ops evaluated under the action-qualified policy keys mcp:connect /
mcp:disconnect (default Prompt) so they keep their human-in-the-loop
confirmation even though the base mcp tool is ToolPolicy::Allow.
