weknora — WeKnora CLI

A command-line interface for the WeKnora RAG knowledge-base server. Lets you authenticate, manage knowledge bases and documents, run hybrid search, and ask streaming RAG questions from your terminal or from an AI agent.

$ weknora --help
Command-line client for the WeKnora RAG server. Manage knowledge bases
and documents, run hybrid search, chat with grounded answers, or expose
a curated read-only MCP tool surface for AI agents.

Available Commands:
  agent       Manage custom agents (CRUD + status/check)
  api         Make a raw API request to the WeKnora server
  auth        Manage authentication credentials and profiles
  chat        Ask a streaming RAG question against a knowledge base
  chunk       Manage document chunks (RAG retrieval debug)
  completion  Generate the autocompletion script for the specified shell
  profile     Manage CLI profiles (named connection targets)
  doc         Manage documents in a knowledge base
  doctor      Run 4 self-checks: base URL, auth, server version, credential storage
  help        Help about any command
  kb          Manage knowledge bases
  link        Bind the current directory to a knowledge base
  mcp         Run weknora as a Model Context Protocol server
  search      Search across chunks, knowledge bases, documents, or sessions

Install

From source

Requires Go 1.26+.

git clone https://github.com/Tencent/WeKnora.git
cd WeKnora/cli
go build -o weknora .
sudo mv weknora /usr/local/bin/   # or anywhere on $PATH

Pre-built binaries

Pre-built binaries for Linux / macOS / Windows are produced by CI on each release. Grab the latest from the Releases page.

---

5-minute quickstart

# 1. Log in to your WeKnora server (interactive password prompt)
weknora auth login --host https://kb.example.com

# 2. Or pipe an API key from stdin (for CI / AI agents)
echo "sk-..." | weknora auth login --host https://kb.example.com --with-token

# 3. List knowledge bases
weknora kb list

# 4. Bind this directory to a knowledge base — subsequent commands auto-resolve --kb
weknora link --kb my-knowledge-base

# 5. Upload a document, then block until parsing finishes
weknora doc upload notes.md
weknora doc wait doc_abc                          # exit 0 completed, 1 failed, 124 --timeout, 130 ^C

# 6. Search
weknora search chunks "what is reciprocal rank fusion?"

# 7. Ask the LLM (streams to terminal)
weknora chat "summarise the design doc"

# 8. Manage custom agents and run them (see `weknora agent --help` / `weknora session --help`)
weknora agent list
weknora session ask --agent ag_abc "what's our q4 retention plan?"

# 9. Inspect a document's chunks for RAG retrieval debug
weknora chunk list --doc doc_xyz

# 10. Health & verification verbs
weknora kb status kb_abc       # fast snapshot: reachable / counts / processing flag (1 HTTP)
weknora kb check kb_abc        # deep verify: also aggregates failed_count via doc list (1+N HTTP)
weknora agent status ag_abc    # fast: reachable / model_id
weknora agent check ag_abc     # deep: probes every KB in the agent's scope

Agent quick start

For AI agents (Claude Code, Cursor, Gemini CLI, etc.) integrating WeKnora:

1. Install: brew install weknora or go install github.com/Tencent/WeKnora/cli@latest
2. Authenticate (background; extract login URL for the user):

   weknora auth login --host <server-url>
   

3. Register MCP in the host's MCP config:

   {"mcpServers": {"weknora": {"command": "weknora", "args": ["mcp", "serve"]}}}
   

4. Read the wire contract before parsing --format json output.
5. Read the exit-10 anti-patterns before any destructive call.

---

Multi-profile

Switch between several WeKnora servers (or several tenants on the same server) without re-logging in:

weknora auth login --host https://prod.example.com    --name prod
weknora auth login --host https://staging.example.com --name staging --with-token < .staging-key
weknora auth list
weknora profile use prod

Credentials are persisted to your OS keyring (Keychain on macOS, libsecret on Linux, Wincred on Windows) when available, otherwise to a 0600-mode file under $XDG_CONFIG_HOME/weknora/secrets/. The active profile lives in ~/.config/weknora/config.yaml.

To remove a profile's stored credentials:

weknora auth logout                  # current profile
weknora auth logout --name staging   # specific
weknora auth logout --all

Wire contract

Designed to be AI-agent-first. Stable across minor releases; breaking changes announced in the changelog and the corresponding weknora --version bump.

Streams

• stdout is the data channel: bare JSON with --format json, or human-formatted output. Never carries error text.
• stderr is logs, progress, warnings, and errors. A non-empty stderr does not mean failure — read the exit code.

JSON output

Every command supports --format json, emitting bare JSON for the resource it produces — an array for list / search, a single object for view and write outcomes:

weknora kb list --format json                              # [{ "id": "kb_x", "name": "Eng" }, …]
weknora kb view kb_x --format json                         # { "id": "kb_x", "name": "Eng", … }
weknora kb list --format json --jq '.[] | {id, name}'      # project to listed fields
weknora kb list --format json --jq '.[].id'                # jq over the bare data

--format ndjson is also accepted for streaming list commands; each element is emitted as its own JSON line. --format json is the default regardless of TTY — running weknora kb list | jq works without an explicit flag. Use --format text for human-readable output.

Errors

On failure, stdout stays empty and the typed error goes to stderr in this format:

<code.namespace>: <message>[: <wrapped cause>]
hint: <actionable next-step>

Example:

auth.unauthenticated: fetch current user: HTTP error 401: ...
hint: run `weknora auth login`

The full code registry is in cli/internal/cmdutil/errors.go (AllCodes()). Code namespaces: auth.* / resource.* / input.* / server.* / network.* / local.* / mcp.* / operation.* (CLI-level wait/poll outcomes: operation.timeout, operation.failed, operation.cancelled).

Exit codes

Code	Meaning	Agent action
0	success	continue
1	typed local.* / operation.failed / unclassified	read stderr, decide retry/abort
2	flag / argument validation error	re-check weknora <cmd> --help
3	auth.* (token missing / expired / forbidden)	re-auth, then retry
4	resource.not_found	verify the resource id
5	input.* (other than confirmation_required)	adjust args, retry
6	server.rate_limited	back off, retry
7	server.* / network.*	transient — retry with backoff
10	input.confirmation_required (high-risk write)	ask the human, retry with -y only after explicit approval
124	operation.timeout (e.g. doc wait --timeout reached)	raise --timeout or check the underlying job
130	operation.cancelled (SIGINT / SIGTERM)	stop, do not retry

Exit 10 is the wire-level signal for "destructive write needs explicit confirmation". Pass -y/--yes on kb delete / doc delete (including --all --kb=<id>) / session delete / profile remove (on the current profile) / agent delete / chunk delete when running headless. Never auto-add -y without the user's explicit go-ahead — exit 10 is the guard against unintended writes.

Other AI-agent ergonomics

• For chat / session ask in AI-agent contexts, pass --format json — streaming tokens to stdout makes JSON parsing impossible.
• --format json composes with the global --profile <name> for single-shot profile overrides without disk writes.
• weknora mcp serve exposes a curated read-only tool surface over stdio MCP for any MCP-compatible client.

Advanced operations not exposed as flags

WeKnora CLI exposes top use cases as polished commands; deep configuration goes through the raw HTTP passthrough. CLI flag coverage targets common workflows, not 1:1 API parity. Examples of deep operations that intentionally go through weknora api:

• Tuning a KB's nested config — chunking strategy, summary model, multimodal extraction defaults, FAQ thresholds, VLM model. Use weknora api PUT /api/v1/knowledge-bases/<id> --input - with a JSON body matching the server's UpdateKnowledgeBaseRequest. (Note: the storage provider is set once at create time via kb create --storage-provider <name> and is not updatable.)
• Per-request chat parameters — multi-KB scope, summary model override, image attachments, web search toggle. Use weknora api POST /api/v1/knowledge-chat/<session-id> --input -.
• Per-request session ask --agent overrides — same shape via weknora api POST /api/v1/agent-chat/<session-id> --input -.
• Operations without a CLI verb — register / change-password / OIDC flows, organization / sharing endpoints, tenant management.

weknora api --help documents the raw passthrough. Run weknora doctor first to verify auth and base URL.

---

Health check

Run weknora doctor for a 4-status diagnostic (OK / warn / fail / skip) covering base URL reachability, authentication, server-CLI version skew, and credential storage backend. Add --format json for machine-readable output, --offline to skip network checks.

For per-resource verification, the status / check verb pair gives a fast vs deep choice:

Verb	Cost	Use
weknora kb status <kb-id>	1 HTTP	live counts / processing flag
weknora kb check <kb-id>	1+N HTTP	adds failed_count via doc-list page-walk
weknora agent status <agent-id>	1 HTTP	reachable / model_id
weknora agent check <agent-id>	1+N HTTP	also probes every KB in the agent's scope

weknora doc wait <doc-id> [<doc-id>...] blocks until each document reaches a terminal parse_status (completed or failed). Exit codes: 0 (all completed), 1 (any failed), 124 (--timeout reached), 130 (Ctrl-C / SIGTERM). Multi-target is polled concurrently (max 5 in flight; pipe through xargs -P for more).
