doction

doction

A self-hosted, markdown-first wiki and knowledge base built for humans and AI agents. Markdown pages with per-page git history, PostgreSQL full-text search plus optional local semantic search, a REST API, and a native MCP server to plug agents in. Runs as an app container + a Postgres container — no API keys, no SaaS, no LLM inside doction itself.

Why doction? Unix-style and boring by design. Your notes are plain markdown in a git repo; search runs locally; agents talk to it over a standard MCP interface. doction does retrieval — the language model lives in your agent, not here.

Every save is a git commit, so any page's history is a real diff:

---

Quick start

cp .env.example .env   # edit POSTGRES_PASSWORD and SECRET_KEY
mkdir -p data/logs     # the container runs non-root as uid 1000
docker compose up      # then open http://localhost:8000 and register

Sign-up is open by default: register your own account, then set DISABLE_REGISTRATION=1 and restart. Connecting an agent is one command with a personal access token:

claude mcp add --transport http doction $DOCTION/api/mcp \
  --header "Authorization: Bearer doction_..."

Documentation

Features, how it works and the map of every page are in docs/, which is published at doction.site. Development setup and the check gate are in CONTRIBUTING.md, the security model and reporting channel in SECURITY.md, and release notes in CHANGELOG.md.
