Find the tenant-isolation gap in your self-hosted, multi-tenant AI-agent platform before an auditor, or an attacker, does.
npm install -g tenantguard-cli
This is the recommended install. The tenantguard-cli npm package (currently 0.2.0, renamed from the old plain tenantguard, which is deprecated) pulls in the matching platform binary as an npm optionalDependency (cosign-verified at publish time, so there's no separate verification step for you) and puts a tenantguard command on your PATH.
Platform coverage: macOS on Intel and Apple Silicon, Linux on x64 and arm64, and Windows on both x64 and arm64.
go install github.com/RudrenduPaul/TenantGuard/cmd/tenantguard@v0.2.0
go install works on every platform Go supports and doesn't depend on any registry publish state, so it's the fallback if your platform isn't covered above.
You can also skip the top-level package and install a single platform binary package directly:
npm install tenantguard-darwin-arm64 # swap for your platform: darwin-x64, linux-x64, linux-arm64, win32-x64, win32-arm64
./node_modules/tenantguard-darwin-arm64/bin/tenantguard scan --demo
pip install tenantguard-cli
uvx --from tenantguard-cli tenantguard scan --demo
The PyPI package, tenantguard-cli, lives in this repo under python/ and is built and tested in CI. Its current version is 0.1.6, which downloads and runs the v0.2.0 build of the same GitHub Releases binary the npm packages use, verifying the release's SHA-256 checksums.txt on first run (itself Sigstore-signature-verified before any digest inside it is trusted) and caching the verified binary locally after that. That's a different trust boundary than the npm packages, which embed a cosign-verified binary at publish time and need no runtime download at all; the PyPI wrapper's checksum check is the equivalent guarantee for a path that has to fetch the binary on the end user's machine instead.
PyPI versions up to and including 0.1.2 shipped a bug that made pip install tenantguard-cli succeed but tenantguard scan --demo fail on first run with could not parse checksums.txt.pem as a PEM certificate (the wrapper wasn't base64-decoding the cosign-produced certificate/signature release assets before parsing them). That is fixed in tenantguard-cli 0.1.3, published to PyPI on 2026-08-03; pip install tenantguard-cli now installs a working tool with no extra steps.

[PASS] 1 check(s) clear
Summary: 14 FAIL, 1 PASS Findings map to confirmed open goclaw issues where applicable. HIPAA citations are provisional, see README.
The bundled fixture is deliberately noisy: it exists to exercise nearly every rule at once. TA08 (credential-storage encryption) and TA14 (per-agent resource-profile isolation) are per-entry checks that only fire against providers and resource_profiles entries in the scanned config, and this fixture declares zero entries of either kind, so both rules have nothing to evaluate and produce no finding at all, neither PASS nor FAIL. TA16 (provider connection SSRF) is the same kind of per-entry check against providers entries, so it also produces nothing on this fixture. The one line shown as passing, "1 check(s) clear," is TA12 (owner/sysadmin recovery), which the fixture's owner_ids and has_recovery_command values are deliberately set to satisfy. Exit code is 1, since findings are present; see CLI Reference for the full exit-code contract.
Scan a real deployment and emit SARIF for code scanning instead:
tenantguard scan --target ./deployment --format sarif --sarif-out tenantguard-report.sarif
Or emit plain JSON, for a script or agent that would rather parse a flat findings array than a SARIF document:
tenantguard scan --target ./deployment --format json
TenantGuard scans a self-hosted, multi-tenant AI-agent deployment's configuration against 16 rules, each derived from a real, confirmed tenant-isolation failure mode. Every rule is fail-closed: an undeclared or ambiguous setting is a violation, not a silent pass.
| Rule | What it catches |
|---|---|
| TA01 | A sandbox/workspace mount is a violation unless its path carries the ${TENANT_ID} scoping placeholder or scoped_per_tenant is explicitly declared true. Maps to goclaw#1163. |
| TA03 | A cron binding's target_agent must belong to the tenant that declared the binding; a dangling or cross-tenant reference fails closed. Maps to goclaw#1217. |
| TA11 | Flags two channel_instances entries that share the same device_session_id but declare different tenants (e.g. a shared WhatsApp device row). Maps to goclaw#1064/#1065. |
| TA14 | A per-agent resource profile (browser/container) is a violation unless its path contains the ${TENANT_ID} placeholder. Maps to goclaw#778. |
| TA15 | Flags a channel_instances entry that doesn't explicitly declare reload_strategy: differential; an undeclared value or full both mean any single create/update/delete on that entry triggers a destructive full stop/restart of every running channel instance across every tenant. Trusts the deployment's own declaration (TenantGuard cannot verify the real loader actually diffs by fingerprint). Maps to goclaw#1147. |
| Rule | What it catches |
|---|---|
| TA02 | Flags a saved MCP tool URL targeting a private/loopback/reserved address, using real net.cidr_contains on a literal or DNS-resolved IP (not string matching), unless the deployment declares both validates_private and pins_resolved_ip (or the host is explicitly allowlisted). Documents the DNS-rebinding/TOCTOU limitation explicitly. Maps to goclaw#1070. |
| TA04 | Flags an exec tool that denies direct env-dump reads but not indirect reads (e.g. jq $ENV), and independently flags any tool with allow_chain_exec: true, since cr
