For Docker nodes, reload bottoms out as a raw POST /containers/{id}/restart
to the Docker daemon, bypassing GNS3's start/stop lifecycle (uBridge
re-attach, console servers, NIC setup). The container restarts at the
Docker level but GNS3's plumbing goes out of sync, and the daemon call can
block up to the controller's 240s timeout — manifesting as "reload hangs /
no response". stop+start runs the full lifecycle and is reliable.
Remove the node_reload and node_reload_all MCP tools (tool functions,
handlers, NODE_TOOLS entry, tests, docs). The underlying REST endpoints
(POST /nodes/{id}/reload, POST /nodes/reload) are kept for native API
users. MCP callers should use node_stop + node_start (partial) or
close/open project (full restart) instead.
The name device_command_run was ambiguous and easily confused with
device_config_send. device_show_run makes the read-only intent explicit,
forming a clear pair: config_send (write) vs show_run (read).
Add documentation explaining how _server_url() resolves the host
when Server.host is 0.0.0.0 or :: — using the default route
interface IP instead of hardcoding 127.0.0.1.
Added Transport Security section to MCP service documentation covering:
- Default behaviour (disabled, allow all hosts)
- How to enable protection via gns3_server.conf
- Protection mechanism (Host header validation)
- DNS rebinding attack prevention explanation
- Behaviour summary table
