The final runtime image (used by langbot/plugin_runtime/box) shipped uv and
docker-cli but no node, so any npx-launched stdio MCP server inside the box
sandbox exited with return_code=127 (command not found). Install Node.js 22
LTS via NodeSource; node/npx land in /usr/bin, which is on the nsjail
read-only mount whitelist (_READONLY_SYSTEM_MOUNTS) and is bound into the
sandbox chroot automatically.
* 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.
Build Dev Image / build-dev-image (push) Has been cancelled
The langbot_box service drives sandbox containers through the docker CLI
(CLISandboxBackend shells out to `docker run`/`docker exec`), but the
image shipped without a docker client, so DockerBackend.is_available()
was always false and the Box sandbox backend was unavailable in Docker
deployments — disabling native tools, skill execution and stdio MCP.
Install docker-ce-cli (client only) in the image, arch-aware so
multi-arch builds work.
Also bump langbot-plugin pin to 0.4.1, which disables proxy
auto-detection on internal control-plane WebSocket connections (the
langbot<->plugin_runtime / langbot<->box handshakes were failing on
hosts that inject a proxy into containers).
Bumps version to 4.10.0-beta.3.
