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.
A heredoc (<<<) closes stdin at once, so websocat dropped the WebSocket
before the device's reply arrived. Add --no-close to the node_console usage
examples and the returned command field so the connection stays open while
output is read.
Token revocation is a strict version check (token_data.token_version !=
user.token_version). create_access_token defaults token_version to 0, so the
short-lived JWTs minted for the console WebSocket URL (nodes) and the download
URLs (symbols, links) carried ver=0. Any user who had logged out at least once
(token_version >= 1, e.g. the default admin) got tokens rejected as "revoked"
on first use.
e433991cf fixed this in _resolve_token's API-key branch but missed these three
independent minting sites. Now resolve token_version during _resolve_token (the
JWT branch decodes it, the API-key branch reads user.token_version), carry it
through gns3_ctx, and pass it at every minting call.
- Batch mode now inherits top-level template_id as default per-node
- Both single and batch modes filter response to minimal fields by default
(node_id, name, node_type, status, console)
- Optional 'fields' parameter overrides the default field set
_ jw t_username_var set in _resolve_token for both JWT and API key auth.
Passed to handlers via gns3_ctx['jwt_username']. No raw key exposure,
no fake-user fallback.
- Each tool accepts either node_id (single) or node_ids (batch)
- Batch mode runs actions in parallel via ThreadPoolExecutor
- Useful for starting/stopping nodes by topology region
- node_create accepts nodes=[{template_id, x, y, name?}] for batch creation
- link_create accepts links=[{nodes, link_type?, filters?}] for batch creation
- Uses ThreadPoolExecutor for parallel REST API calls
- Max 10 concurrent workers per batch, backward compatible with single mode
- Move node file operations (list_files, delete_file) from Gns3Connector to Node class
- Add link capture/reset operations (reset, start_capture, stop_capture) to Link class
- Convert all MCP handlers to use conn.http_call() directly instead of
Gns3Connector/Node/Link abstraction methods
- Register 4 new MCP tools: reset_link, start_capture, stop_capture,
download_capture_file
- Add list_node_files, get_node_file, write_node_file, delete_node_file methods to Gns3Connector
- Add MCP handlers with offset/limit line-based reading for get_node_file
- Auto-truncate files >50KB with truncated flag in response
- Rich metadata returned (total_lines, total_bytes, has_more, etc.)
- Tool docstrings guide AI to check file sizes before reading chunked
Extended the kwargs parameter handling fix to nodes and links MCP tools,
which had the same nested kwargs structure issue as templates.
Changes:
- Modified update_node_handler to extract params from nested kwargs
- Modified update_link_handler to extract params from nested kwargs
This ensures that node and link updates through MCP tools work correctly,
allowing proper modification of node and link properties.
