/**
 * Per-agent MCP availability endpoints, mirroring the per-workflow ones on
 * `McpSettingsController` (`/mcp/workflows`). They live in the agents module
 * so they only exist when the module is active.
 *
 * No `@ProjectScope` decorators: these routes carry no project in their URL,
 * so `AgentMcpAccessService` enforces the `agent:update` scope per project
 * instead — same reasoning as the workflow toggle endpoint.
