Common questions

Is Paqtra safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: PAQTRA_URL, PAQTRA_TOKEN, PAQTRA_PASSWORD

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.2.3) reached the registry 24 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Docker on your computer.

What can I use instead?

Paqtra

Why can't A reach B? Paqtra traces every flow and shows Cilium's verdict.

Cilium-native network observability and operations for Kubernetes. Every Hubble flow stored and searchable, drops explained by Cilium reason, CiliumNetworkPolicy changes simulated before you apply them, and enforcement left with Cilium.

Web dashboard · REST API · Terminal TUI · Why denied? on any flow · Read-only toward the datapath · Free, Apache 2.0

📖 [Read the full docs](https://zyvorai.github.io/zyvor-paqtra/): quickstart, architecture, the Cilium boundary, and a product tour.

What's new


Per-second metrics platform (Unreleased)	Every agent streams host, network, disk, pod, process-group and app metrics each second; the API keeps them in 1 s / 1 min / 1 h tiers, adds Hubble flow, verdict, drop, HTTP and DNS series, flags anomalies per dimension, runs 45 built-in metric alerts and exports to Prometheus remote write, OTLP or Graphite. docs/metrics.md
MCP server (2.2.3)	`paqtra-mcp`, a read-only stdio MCP server with 39 tools, lets an AI agent query a Paqtra deployment with the caller's own credentials. Published from the v2.2.3 release as `ghcr.io/zyvorai/paqtra-mcp:2.2.3` and to the MCP Registry as `io.github.zyvorai/paqtra`. docs/mcp-integration.md
Installs like `cilium-cli` (2.2.0)	The Helm chart is compiled into the `paqtra` binary: `install`, `upgrade`, `status --wait`, `--with-cilium`, prerequisite checks, `doctor`.
Signed releases (2.2.0)	Static musl Linux and macOS binaries with `sha256sums.txt`, a cosign keyless signature, an SBOM and a Homebrew formula.
Rule-level policy editing (2.2.0)	Add, replace or delete one rule of a `CiliumNetworkPolicy`, with `?dry_run=true`, conflict detection and audit entries.
Cilium Insights (2.2.0)	Read-only views of Cilium features, Hubble nodes, BGP, LB-IPAM, L2, pod IP pools, CIDR groups and Gateway API resources.
Change impact and shareable investigations (2.2.0)	Before/after flow correlation for a change, and investigation bundles with a time-limited, redacted share link.
Why denied? (2.1.0)	From any dropped flow: identities, candidate CNP/CCNP, the drop reason and a draft allow.
Large flow stores stay fast (2.2.1, 2.2.2)	Reads never block ingest, every read has a deadline, and recent-window queries go through the time index.

Full history: CHANGELOG.md.

Why Paqtra

When this happens…	Paqtra gives you…
A request fails and nobody knows why	Path explain and Why denied? on any flow, with confidence-tagged evidence
Cilium drops packets and the reason is buried	Drop analytics by Cilium reason, plus a per-packet explanation
You want to change policy without breaking things	Simulate a `CiliumNetworkPolicy` against indexed flows before you apply it
The flow you need scrolled out of Hubble minutes ago	A continuous Hubble follow-stream into a local SQLite flow store, queried by time window
Network tooling that touches the datapath is a non-starter	Read-only toward Cilium: no BPF map writes, no program attach, not a second CNI
Every Cilium add-on needs its own install story	`paqtra install` with the Helm chart built in, `paqtra status --wait`, `paqtra doctor`

Paqtra is observe-first. Flows come from Hubble; node-local enrichment may read the BPF map inventory. Enforcement stays with Cilium: policy changes go through CiliumNetworkPolicy (CNP), never through Paqtra's own datapath.

Paqtra vs Hubble UI

Paqtra does not replace Hubble; it reads Hubble's flows through Hubble Relay and builds on them.

	Paqtra	Hubble UI (ships with Cilium)
Flow source	Hubble Observer gRPC follow-stream	Hubble Relay
Flow history	Local SQLite flow store, queried by time window	Live flows from Hubble's in-memory buffers
Service map	Service map and observed-traffic topology	Service map per namespace
"Why can't A reach B?"	Path explain with observed / inferred / unavailable evidence	Inspect the flows yourself
Drops	Drop analytics by Cilium reason, Why denied? per flow	Verdict and drop reason on each flow
Policy	Rule builder, YAML editor, AutoPolicy, simulate, apply as CNP	Not a policy editor
Interfaces	Web dashboard, REST API, terminal UI, CLI	Web UI (plus the `hubble` CLI)
Choose Hubble UI when		Live flows and a service map are all you need and you want only what ships with Cilium

Observe

Live Hubble flows with verdict coloring and WebSocket streaming, a service map and an observed-traffic topology built from real flows. Real L7 DNS query/rcode/latency when Cilium DNS visibility is on; L4-only never invents SERVFAIL. Capabilities →

Per-second node metrics next to the flows: CPU, memory, disks, interfaces, TCP, conntrack, pod cgroups, process groups (by comm only) and annotated apps (nginx, Redis, Envoy, CoreDNS, etcd, any Prometheus endpoint), with live canvas charts, per-dimension anomaly detection, "what changed here?" correlation and Netdata-style metric alerts that notify but never apply policy. paqtra metrics … covers the same from the terminal. Metrics → · Alerts → · Anomalies → · Apps →

Investigate

Ask "why can't A reach B?" and get an answer with observed, inferred or unavailable evidence labels. Click Why denied? on any dropped flow. Investigate → · Root cause →

The dashboard also includes real kernel eBPF data views powered by bpftool: conntrack tables, policy maps, IP cache, LB maps and drop analytics. All read-only. eBPF integration →

Secure

A visual rule builder, a YAML editor, ML-powered AutoPolicy and an evidence-backed simulator, all applied as CiliumNetworkPolicy through the Kubernetes API. Cilium enforces. AutoPolicy → · Simulator →

Also included: compliance audits (CIS, NIST, SOC 2), anomaly detection, chaos engineering, canary deployments and multi-cluster views. Everything Paqtra does →

MCP

paqtra-mcp is a stdio Model Context Protocol server that lets an AI agent (Claude Desktop, Hermes Agent, any MCP client) read a running Paqtra deployment. It exposes 39 tools, all read-only with respect to the cluster: no policy apply, edit or delete, no chaos, no healer fix, no cluster sync, no flow-store purge. The two investigate tools store an evidence bundle in the API and nothing else. Every call is made with your own API credentials, so RBAC and namespace scoping apply.

Registry name: io.github.zyvorai/paqtra (published from the v2.2.3 release)
Image: ghcr.io/zyvorai/paqtra-mcp:2.2.3
Configuration: PAQTRA_URL, plus PAQTRA_TOKEN or PAQTRA_USERNAME / PAQTRA_PASSWORD; use a viewer-role account.

Setup, tool scope and the protocol: docs/mcp-integration.md.

How it fits together

Component	Port	Role
API (`ghcr.io/zyvorai/paqtra-api`)	`9191`	Rust + Axum REST API: Hubble ingest into the flow store, investigate, drops, policy, JWT auth
UI (`ghcr.io/zyvorai/paqtra-ui`)	`8443`	React dashboard, served over TLS by default
Node agent (`ghcr.io/zyvorai/paqtra`)	`9192`	DaemonSet on every node: health and read-only map and program inventory
`paqtra` CLI	—	Install, upgrade, status, doctor, `ui`, `hubble enable`; the Helm chart is built in

Ports are the Helm chart defaults in chart/values.yaml. Architecture in depth: docs/architecture.md · docs/web-architecture.md.

What Paqtra never does

Hard boundaries, enforced by review and repeated in AGENTS.md:

Never writes Cilium BPF maps or pins over cil_* programs.
Never attaches, detaches or replaces Cilium (or Netra) programs. Attachment inventory is read-only classification (cil_* / netra_* / other).
The agent observes, reports health and inventories. Policy apply goes through Cilium CRDs.
Does not collect application payloads, argv/cmdline, or Secret contents.
Does not introduce a second CNI or compete with Cilium's datapath.
Prefers Hubble for flows; uses maps for node-local enrichment only.

Details: docs/cilium-brotherhood.md and docs/ebpf-integration.md.

Quickstart

Prerequisites: a Kubernetes cluster and a kube-context. Cilium with Hubble Relay is required too; paqtra install --with-cilium sets it up if it is missing.

# Install the CLI (downloads, verifies and installs the latest release)

curl -fsSL https://raw.githubusercontent.com/zyvorai/paqtra/main/install.sh | sh # or: brew install zyvorai/tap/paqtra

Install Paqtra into the current kube-context (the Helm chart is built in)

paqtra install # add --with-cilium if the cluster has no Cilium yet paqtra status --wait paqtra ui # open the console

Something wrong?
