link_capture_download and get_symbol embedded a 10-min JWT in the
Authorization header of the curl command they return; LLM clients
retyping that command corrupted the long token — the same failure
class as the console WebSocket URLs fixed in the previous commit.
Generalize the ticket store (console_tickets.py -> access_tickets.py,
ConsoleTicketService -> AccessTicketService): a ticket now binds to
either a node's console endpoints (WebSocket, matched against route
path params) or one exact REST resource path (capture file, symbol
image). The two binding modes are isolated — a node-bound ticket
cannot authenticate a REST resource and vice versa.
get_user_from_token redeems path-bound tickets through the existing
token parameter / Bearer header, matched exactly against
request.url.path, then reuses the shared user lookup and token_version
revocation checks. Download URLs embed ?token=<ticket> and the curl
commands no longer carry a Bearer header.
LLM clients transcribing the console WebSocket URL into shell commands
reliably corrupted the ~200-char JWT embedded in it (dropped header
segment -> "MissingAlgorithmError: Missing 'alg' value in header" on
every connection attempt). The node_console tool now mints a short
random ticket ("gns3t_" + 16 urlsafe chars, 10 min TTL, multi-use)
stored server-side and bound to the node's console endpoints:
- new ConsoleTicketService (gns3server/services/console_tickets.py),
in-memory store with lazy expiry sweeps
- get_current_active_user_from_websocket redeems tickets through the
existing "token" query parameter, gated on websocket.path_params so a
ticket only authenticates the console/ws and console/vnc routes of
the node it was minted for; the JWT path is unchanged
- redemption reuses the existing user lookup, token_version revocation
and is_active checks, so logging out invalidates outstanding tickets
- vnc_url no longer embeds the full session JWT
- the tool docstring now tells clients to run the returned command
verbatim instead of reconstructing the URL
The controller assigns default names (R-1, R-2, ...) and console ports
in request arrival order. A parallel batch fan-out lets thread scheduling
decide that order, so the first submitted node could end up as R-2.
Batches that rely on default naming (any node without a name) are now
created sequentially; batches with explicit names stay parallel. The
node_create tool description documents the ordering semantics and tells
callers to correlate nodes by node_id.
Splitting the file with keepends=False and rejoining with newlines
dropped the trailing newline of the last line (and every \r of CRLF
files), so returned content was shorter than the file on disk and did
not round-trip. Split with keepends=True and join the selected lines
verbatim; pagination semantics are unchanged.
Batch node/link creation collected results with as_completed, so the
response order followed completion rather than the submitted array and
callers could not correlate entries. Collect in submission order via
pool.map, and report batch deletes as status=success like every other
batch action (the message still says what was deleted).
Per-link markers on serial links need the WAN encapsulation (e.g.
DLT_C_HDLC) so the BPF compiles against the right link layer — the
REST API already accepts it, but the MCP tool never forwarded it.
Create passes it through; update ignores it (changing it would
invalidate the capture file), matching the REST schema semantics.
- Slim custom_gns3fy.py to connector-only Gns3Connector and rename to
connector.py; delete the unused Node/Link/Project dataclasses and
endpoint wrapper methods (~3000 lines)
- Move the MCP node/link handler implementations into
gns3_client/api_handlers.py as the shared REST client layer consumed
by both the MCP service and copilot tools; add available_filters
handler (exposed as link_available_filters MCP tool) and
build_gns3_ctx() for copilot callers
- Rewrite the tools_v2 node/link tools on top of the handlers: batch
lifecycle actions now run in parallel, node creation is a single
POST, project-wide status reads replace per-node GETs
- Port Project.nodes_inventory/links_summary aggregation into
project_inventory.py (output shape preserved) and rewrite the
topology reader / project info tools on it, dropping the unused
stats/snapshots/drawings calls
- Delete the dead mcp/nodes.py and mcp/links.py (NODE_TOOLS/LINK_TOOLS
had no consumers; __init__ imports handlers from api_handlers)
- Retarget mcp handler tests to patch api_handlers._get_connector and
replace test_custom_gns3fy.py with inventory contract tests
