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.
_ 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.
- 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
Updated the filters parameter description in create_link and update_link
MCP tools to specify the required array format and provide examples.
Changes:
- Updated create_link filters description with array format requirements
- Updated update_link filters description with array format and example
- Added specific filter types: frequency_drop, packet_loss, delay, corrupt, bpf
This helps users understand the correct format:
- frequency_drop: [N] (drop every Nth packet)
- packet_loss: [rate] (packet loss percentage)
- delay: [ms, jitter] (latency and jitter in milliseconds)
- corrupt: [rate] (packet corruption percentage)
- bpf: [expression] (Berkeley Packet Filter)
Prevents TypeError: 'int' object is not iterable errors.
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.
