Citadel

A self-hosted Organization Vault — shared, access-controlled memory for your team and its AI agents. Built on Cognee.

Citadel turns approved sources — commits, sessions, docs, issues — into structured, source-linked knowledge, and exposes it to people and agents through a CLI, a hosted MCP endpoint, an HTTP API, and a web UI. Capture is personal-by-default (your private Node); the shared Central vault evolves only through governed promotion and org sync.

Features

• One-command onboarding — citadel onboard wires the seat token, autosync git/session hooks, MCP server, and capture roots. Idempotent, self-contained.
• Autonomous capture — fail-silent git pre-push + Claude Code SessionEnd hooks snapshot work to your private Node. No per-session ceremony.
• Headless by design — every teammate command speaks --json, so Claude / Codex / Cursor and CI can drive it. Token from env, never argv.
• Hosted MCP — agents connect with a URL + token; citadel_search to read, citadel_ingest / citadel_contribute to write. Per-call audit.
• Governed sharing — seat writes stay on your Node; Central updates via org sync and the Promotion Agent. Secrets blocked on every write path.
• Live knowledge graph — Central + all seat Nodes on one canvas, plus a real-time activity timeline in the web UI.
• Zero-dependency client — pip install citadel-archive is pure stdlib; the server stack is an opt-in extra.

Quick start

Teammate CLI

pipx install citadel-archive          # the `citadel` command (zero-dep client)
# upgrade: pipx install --force citadel-archive --pip-args=--no-cache-dir

citadel onboard                       # token + hooks + MCP + capture roots (idempotent)
citadel status                        # connection · identity · local setup  (--json for agents)

No Python yet? The bootstrap installer checks for Python 3.10+, asks before installing it if it's missing, then sets up pipx + the CLI:

curl -fsSL https://raw.githubusercontent.com/masumi-network/Citadel-Archive/main/install.sh | sh

(citadel is a Python tool; pipx keeps its interpreter isolated so you don't manage Python yourself. Add -s -- -y to skip prompts, --dry-run to preview.)

citadel onboard installs the bundled autosync hooks (kb.hooks.* — no vendored skill), writes the seat token to your shell rc (masked), adds the MCP server, and offers Approved Capture Roots. Get a ctdl_… seat token from a vault admin (the Access page or POST /api/access/tokens). One token per person or agent; rotate anything that lands in chat or logs.

Self-host the server

uv sync --dev                         # full server stack (cognee, fastapi, …)
cp .env.example .env                  # set providers, access keys, database
uv run uvicorn kb.server:app --reload --port 8000

Open http://localhost:8000/ for the UI. See docs/operations.md for deployment, environment, and integrations.

How it works

Concept	What it is
Node (seat:{slug})	Your private working memory. Default target for all capture.
Central (masumi-network)	The shared org vault. Read-only for seats; evolves via sync + promotion.
Capture	Approved Capture Roots auto-sync to your Node; everything else needs approval.
Promotion	A Promotion Agent moves qualifying Node knowledge into Central (tag-governed).

Four surfaces sit on the same FastAPI process and the same ctdl_ tokens: the CLI, the hosted MCP endpoint (/mcp/), the HTTP API, and the web UI. The domain language is defined in CONTEXT.md; architecture decisions live in docs/adr/.

Usage

CLI

citadel onboard                       # one-command setup
citadel doctor [--fix]                # diagnose (and repair) your local setup
citadel status [--json]               # health + identity + local setup + knowledge mesh
citadel capture [--dry-run] [--json]  # push summaries of Approved Capture Roots
citadel search "what did we decide about the vault?"   # HTTP-backed via your seat (--json)
citadel ingest "A durable note" --tag decision         # → your seat Node, cognified inline
citadel mcp add cursor                # wire another coding tool to the hosted MCP
citadel seat create "Jane Dev" jane   # admin: mint a seat + its seat-scoped writer token

MCP (hosted)

Agents connect with a URL and a token — no clone, no local Python. Add to a project .mcp.json:

{
  "mcpServers": {
    "citadel": {
      "type": "http",
      "url": "https://citadel-archive-production.up.railway.app/mcp/",
      "headers": { "Authorization": "Bearer ${CITADEL_MCP_ACCESS_TOKEN}" }
    }
  }
}

HTTP API

export CITADEL_BASE_URL=https://citadel-archive-production.up.railway.app

# Read — flat, agent-friendly alias over search
curl -fsS -H "Authorization: Bearer $CITADEL_MCP_ACCESS_TOKEN" \
  "$CITADEL_BASE_URL/api/knowledge?q=payment+flow&limit=5"

# Contribute (writer) — routed through the Learning Process with conflict detection
curl -fsS -X POST "$CITADEL_BASE_URL/api/contribute" \
  -H "Authorization: Bearer $CITADEL_MCP_ACCESS_TOKEN" -H "Content-Type: application/json" \
  --data '{"title":"Decision: deepseek-v4-flash","content":"Standardized on it via OpenRouter.","tags":["decision"]}'

Full endpoint reference: docs/operations.md.

Python

import asyncio
from kb import Citadel

async def main() -> None:
    kb = Citadel.from_env()
    await kb.ingest("Citadel keeps my Organization Vault organized.", tags=["personal"])
    print(await kb.search("What does Citadel do?"))

asyncio.run(main())

Skills & agent discovery

The agent skills live in skills/ and are installable straight from this repo:

npx skills add masumi-network/Citadel-Archive

The hosted /skills index and the discovery manifest publish each skill's sha256 / SRI integrity and the MCP endpoint, token requirements, and public/private boundary — without exposing vault content.

Contributing

Issues and pull requests welcome. Tests run with uv run pytest; lint with uv run ruff check .. Keep the lightweight client free of server dependencies — the base package is stdlib-only (a test guards the import boundary).
