Bridge accepts an optional default probe URL via `--connect <url>` (or `GAMMARAY_PROBE_URL` env). At runtime the connection is driven by `connectProbe`/`disconnectProbe` MCP tools; the URL is remembered so tools can auto-reconnect after a probe restart. The bridge's `GammaRaySession` state machine (`Disconnected → Connecting → Ready`, with `→ Failed` on persistent error) is the single source of truth; `probeStatus()` reports it to the client.
The bridge acts as an MCP server on stdio. The LLM host (e.g. Claude Desktop, opencode) launches the bridge as a subprocess and communicates via JSON-RPC over stdio.

## Key gotchas to remember
1. **Protocol version lock**: probe and client must be same GammaRay build. System package too old → build from 3.4.0 source. (`common/protocol.h:141`)
2. **GPL-2.0-or-later**: bridge linking gammaray_client must be GPL-compatible. Accepted. qtmcp offers GPL-2.0-only option — compatible.
2. **GPL-2.0-or-later**: bridge linking gammaray_client must be GPL-compatible. Accepted. qtmcp offers LGPL-3.0-only / GPL-2.0-only / GPL-3.0-only — we comply under GPL-2.0-only.
3. **Qt private headers**: GammaRay build needs `qt6-base-private-dev`, `qt6-declarative-private-dev`. The bridge itself only needs public Qt + installed GammaRay headers. **qtmcp requires Qt 6.8+** (newer than GammaRay's 6.5+ floor); ensure build environment Qt >= 6.8.
4. **C++20**: qtmcp requires C++20. Bridge project set to C++20; GammaRay C++17 libs link fine.
5. **Models only available after `ClientConnectionManager::ready()`** — do not call `ObjectBroker::model()` before handshake completes. MCP tool calls arriving before probe connection should return an error or wait.

The bridge is a GammaRay **client**: it connects to a probe injected into a target Qt app, reads the same models the GammaRay GUI uses, and translates them into MCP JSON-RPC tool calls over stdio. Supports both QML Quick apps (SceneGraph, QML items) and Qt Widget apps (widget hierarchy, properties, attributes).
