Arkon is a self-hosted, enterprise-grade knowledge management layer that bridges organizational data and AI clients. It runs as a centralized MCP Server (Model Context Protocol), compiling your SOPs, policies, and internal docs into a structured, traceable knowledge wiki - then serving that wiki to Claude and other LLMs through a single permission-scoped endpoint.

In most organizations, AI adoption is fragmented. Employees copy-paste documents into chatbots, producing inconsistent context, security risks, and duplicated work.

Arkon treats AI as a managed organizational resource. Every employee gets the right context, automatically and securely - filtered by their department, project membership, and role.

Unlike a vector database that just chunks and indexes, Arkon's MRP pipeline (Map → Reduce → Plan-review → Refine → Verify → Commit) actually compiles documents into a coherent wiki of interlinked pages.

• Plan review before write: every ingestion produces a human-reviewable plan listing which wiki pages will be created or updated. Editors can regenerate the plan with feedback before any page is written.
• Page merge instead of overwrite: when a new source touches an existing wiki page, content is LLM-merged so prior knowledge is never lost.
• Traceable claims: every page records the source documents it was compiled from.
• Image-aware: vision captions are baked into source text before compilation, so wiki pages reference the right images in the right places.
• Resumable: drafts persist mid-pipeline; a crashed run resumes without re-doing the expensive LLM work.

• Three-panel layout: page tree, content, backlinks & outlinks.
• Full-text + semantic (pgvector) search.
• Interactive knowledge graph visualization (per-scope or global).
• Wikilink-style cross-references between pages.
• Version history and rollback on every page.
• Draft proposal → editor review → approval workflow.

Cross-functional contexts with their own scoped wiki, document set, and member roster.

• Department-level isolation for HR, Legal, Engineering, etc.
• Project workspaces for cross-functional initiatives or clients.
• Hard scope enforcement: members only see knowledge from their assigned scopes - at the API, MCP, and search layers.

Role-based access control at department + workspace level.

• Built-in roles: Viewer · Contributor · Editor · Admin (and admin-defined custom roles).
• Granular permissions (doc:read:own_dept, wiki:edit:all, org:settings:manage, ...).
• Audit log for every privileged action - settings changes, plan approvals, role updates.

Employees connect Claude Desktop or Claude.ai to Arkon via OAuth 2.1 + PKCE — just add the server URL and sign in through the browser. No manual token copying required. The MCP server exposes:

• Wiki tools - search_wiki, read_wiki_page, list_wiki_pages, read_wiki_index.
• Source drill-down - get_source, get_source_outline, get_source_pages, list_sources.
• Edit workflow - propose_wiki_edit, edit_wiki_page, list_pending_drafts, review_draft, approve_draft, reject_draft.
• Discovery - list_knowledge_types, get_knowledge_type_docs.

All tools enforce per-token scope (department, knowledge type, source list).

Upload custom agent packages once and distribute them across the org.

• Versioned skill packages (.zip with SKILL.md).
• Department-scoped visibility.
• Contribution workflow for end-user updates.

Catalog-driven selection - admins pick from a curated list with context window, cost, and capability metadata on display.

• LLM: Anthropic Claude (Opus / Sonnet / Haiku 4.x), Google Gemini (3.x Pro / Flash / Flash-Lite, 2.5), OpenAI (GPT-5.x, GPT-4.x).
• Embedding: Google gemini-embedding-*, OpenAI text-embedding-3-* - switchable with online re-embed migration (active model atomically flipped on completion, no zero-result search window).
• Vision: Google Gemini Flash, OpenAI GPT-4o family.

• Self-hosted. Deploy on-prem or in your private cloud via Docker.
• No telemetry. Outbound traffic goes only to the AI provider you choose.
• Encrypted at rest. API keys stored with Fernet encryption in PostgreSQL.

• Backend: FastAPI · PostgreSQL + pgvector · Redis (arq workers) · MinIO
• Frontend: Next.js · Tailwind CSS
• AI integration: Model Context Protocol via FastMCP
• Document parsing: PDF, DOCX, DOC, plain text, URLs, embedded images

Arkon runs 7 Docker containers (PostgreSQL + pgvector, Redis, MinIO, FastAPI API, 2 ARQ workers, Next.js frontend). The table below provides recommended configurations based on team size:

Prerequisites: Docker & Docker Compose, plus an API key from your preferred AI provider (Anthropic, Google, or OpenAI).

1. Clone the repository:

   git clone https://github.com/nduckmink/arkon.git
   cd arkon

2. Configure environment:

   cp .env.docker.example .env.docker
   # Edit .env.docker - set SECRET_KEY, admin credentials, and Postgres/MinIO secrets

3. Launch:

   docker compose --env-file .env.docker up -d --build

4. Access the portal at http://localhost:3119, sign in as admin, then go to Settings to pick your embedding / LLM / vision models and paste API keys.

→ See Setup Guide for development mode and the full env reference.

In Claude Desktop or Claude.ai → Settings → Connectors, add a custom connector:

• Name: Arkon
• URL: https://your-arkon-server/mcp

Click Connect → a browser window opens with the Arkon login form → sign in with your Arkon credentials → done. Arkon uses OAuth 2.1 + PKCE so no manual token setup is required.

To make Claude consistently use Arkon, add this to Claude's Custom Instructions (Settings → Custom Instructions):

Whenever answering questions related to the company — its processes, products,
people, departments, policies, or projects — always search Arkon first using
the search_wiki tool before relying on general knowledge.

For stronger enforcement, create a Project in Claude Desktop, attach Arkon as a connector, and paste the same text as Project Instructions.

→ See MCP & Claude for the complete tool reference.
