refactor(mcp): make MCP test reuse the shared Box session (near-instant tests) (#2304)
* refactor(mcp): make MCP test reuse the shared Box session instead of a per-test session Testing an MCP server (config-page "test" button) previously spun up a fresh isolated mcp-test-<uuid> Box session every time: cold-start the container, run the dependency bootstrap, probe, then tear the whole session down. That is slow (tens of seconds) and, on an already-hosted server, wasteful — the server is already running in the shared session. Change the test to reuse the shared session / live process: - _build_box_session_id: transient tests now use mcp-shared, the same Box session as live servers, so a test reuses the running container (and, for an existing server, its live managed process) instead of a cold per-test session. - cleanup_session: a transient test no longer deletes the whole session (which under the shared model would kill every other MCP server in the container). It stops only its own process_id, exactly like a live server. Isolation is now at the process level (distinct process_id per server/test), not the session level. - test_mcp_server (persisted server): reuse the live connection with a real list_tools refresh/probe; only fall back to a full start() when there is no live connection to probe or the refresh fails, instead of an ERROR->start() rebuild. Trade-off: a failing test now shares the container with live servers rather than a throwaway session. Accepted deliberately in favour of near-instant tests; process-level isolation keeps a test from stopping another server's process. * chore(deps): pin langbot-plugin 0.4.9 for the nsjail RLIMIT_AS node/npx MCP fix --------- Co-authored-by: dadachann <185672915+dadachann@users.noreply.github.com> |

feat(mcp): simplify external MCP server config to local/remote modes
Replace the three-way transport choice (stdio / sse / httpstream) for connecting LangBot to external MCP servers with two modes: local (stdio) and remote. Remote servers only require a URL; the runtime auto-detects the transport (tries Streamable HTTP, falls back to SSE). - provider/tools/loaders/mcp.py: add _init_remote_server() with Streamable-HTTP-then-SSE probing; dispatch 'remote' lifecycle, keep legacy sse/http branches for back-compat - plugin/connector.py: normalize legacy http/sse marketplace modes to 'remote' on Space install, preserving connection params - entity/persistence/mcp.py: document mode as stdio, remote (legacy: sse, http) - alembic 0006: idempotent data migration mapping existing sse/http rows to remote (downgrade maps back to http) - api/http/service/mcp.py: stash runtime_info (status + tool list) into test task metadata before tearing down the temp session - web: collapse mode dropdown to local/remote, remote renders URL+timeout only, edit auto-maps legacy sse/http to remote; show tools after test in create mode from task metadata; remove dead plugins/mcp-server/ tree - i18n: local/remote labels + mode/url hints across 8 locales |

Feat/saas sandbox adaptation (#2234)
* fix(box): trust Box-reported skill paths when filesystem is not shared
In separated deployments (Docker Compose, k8s sidecar, --standalone-box,
remote runtime.endpoint) the Box runtime owns its own filesystem, so the
skill package_root it reports via list_skills is not resolvable on the
LangBot side. LangBot's reload_skills and build_skill_extra_mounts
validated those paths with os.path.isdir() against its own filesystem,
which silently dropped every skill in such deployments — breaking the
sandbox skill feature for the nsjail/SaaS backend.
Add BoxService.shares_filesystem_with_box, derived from the connector
transport (stdio = shared, WebSocket = separated), with an explicit
override seam for tests/embedders. Gate both isdir() guards on it: keep
local validation in shared-fs stdio mode, trust Box-reported paths
otherwise. The Box runtime only reports skills found on its own
filesystem, so those paths are valid there by construction.
Adds topology-derivation tests (real connector, no mocks) and
skill-retention tests for both shared and separated filesystems.
* build(docker): ship a self-contained nsjail sandbox backend in the image
Compile nsjail 3.6 from source in a dedicated multi-stage build and carry
only the binary plus its runtime libs (libprotobuf32, libnl-route-3-200)
into the final image. This lets the Box runtime isolate sandboxed code via
nsjail user/mount/pid/net namespaces without a host Docker socket — the
prerequisite for running Box on LangBot Cloud (k8s), where mounting
docker.sock would grant node root and is not acceptable for multi-tenant.
The build toolchain (build-essential/bison/flex/protobuf-dev/libnl-dev)
stays in the nsjail-build stage and is not present in the shipped image.
Verified: image builds (583MB), nsjail --help exits 0, libraries resolve,
and the real NsjailBackend executes an isolated command end-to-end on a
v6.1/cgroup2 host matching LangBot Cloud prod (rlimit fallback path, since
container /sys/fs/cgroup is read-only; PID-namespace isolation confirmed).
* feat(box): SaaS guard to force a single global sandbox scope
Add system.limitation.force_box_session_id_template: when non-empty it
overrides every pipeline's box-session-id-template at resolve time, pinning
all queries to one shared sandbox (e.g. {global}). This is the authoritative,
unbypassable guard — it runs on every exec call, so editing the pipeline
config via API cannot escape it. The web UI locks the Sandbox Scope selector
via a combined box_scope_editable flag (box available AND not forced).
* build(deps): pin langbot-plugin==0.4.2b1 (nsjail cgroup container-safety beta)
* fix(web): show forced sandbox scope + make disabled tooltip tap-friendly
When a SaaS deployment pins every pipeline to a fixed sandbox scope via
system.limitation.force_box_session_id_template, the Sandbox Scope selector was
correctly locked but still displayed the pipeline's stored value (e.g. the
per-chat default), misrepresenting the scope that the runtime actually enforces
on every exec. Coerce the displayed/saved value to the forced template so the
locked selector truthfully shows the active scope (e.g. Global).
Also fix the disabled_tooltip being invisible on touch devices: hover-only Radix
tooltips never open without a pointer, so the explanation of why the field is
locked could not be read on mobile. Wrap the info icon so a tap toggles the
tooltip while desktop hover still works.
* feat(web): hide sidebar new-version prompt for edition=cloud
Cloud instances are upgraded centrally by the operator, so surfacing a GitHub
'new version available' badge to tenants is misleading and actionable only by
the operator. Skip the release check entirely when edition=cloud.
* style(web): prettier formatting for DisabledTooltipIcon ternary
* chore(deps): bump langbot-plugin to 0.4.2b2
Picks up the SDK fix that creates a read-write host_path before the
nsjail bind-mount, fixing the SaaS MCP shared-workspace sandbox failure
(exec exit 255 with empty output when host_path didn't exist).
* chore(deps): bump langbot-plugin to 0.4.2b3
Picks up the nsjail /dev-node fix so stdio MCP servers (uvx-launched) can
start under force_global_sandbox instead of failing with 'Connection closed
/ please check URL'.
* fix(web): show real MCP runtime status on installed extensions list
The installed-extensions list badge keyed solely off the enable flag, so a
server that was still CONNECTING (or in ERROR) was shown as 'Connected'.
Reflect the actual runtime_info.status (connecting/connected/error/disabled)
with matching colors, and poll quietly every 3s while any MCP server is
connecting so the badge transitions without a manual refresh.
* chore(deps): bump langbot-plugin to 0.4.2b4
Picks up the 30s start_managed_process timeout so cold uvx MCP bootstraps
don't get torn down mid-install.
* style(web): satisfy prettier — parenthesize nullish-coalescing in ternary
* fix(mcp): isolate transient test sessions from the shared Box session
A config-page 'test' (server_name='_', no persisted UUID) ran in the same
shared 'mcp-shared' Box session as live MCP servers. A failing test (e.g.
empty args) churned that shared session and tore down healthy, already-
connected servers — leaving them stuck after exhausting their retries.
Mark UUID-less sessions as transient, give them their own isolated Box
session ('mcp-test-<uuid>'), and fully delete that session on cleanup so
tests can never disturb live servers and don't leak sessions.
* fix(mcp): tear down transient test session after test completes
A successful config-page test left its isolated 'mcp-test-<uuid>' Box
session running (the lifecycle task blocks until shutdown). Wrap the
transient test coroutine so it always shuts the session down afterward,
preventing isolated test sessions from leaking.
