Setup

First, ask the user: local server or remote server?

• Local — install and run demarkus on this machine (default)
• Remote — connect to an existing demarkus server (the user must provide the server URL and a write token)

Option A: Local Server

Check if already installed:

which demarkus

If not found, install the full stack (client, server, MCP binary, daemon):

curl -fsSL https://raw.githubusercontent.com/latebit-io/demarkus/main/install.sh | bash

Store the token and register demarkus-mcp with mcporter:

if [ "$(uname)" = "Darwin" ]; then
  TOKEN=$(cat ~/.demarkus/initial-token.txt)
else
  TOKEN=$(sudo cat /etc/demarkus/initial-token.txt)
fi

demarkus token add mark://localhost "$TOKEN"

mcporter config add demarkus \
  --command demarkus-mcp \
  --arg -host --arg "mark://localhost" \
  --arg -insecure \
  --scope home

Option B: Remote Server

Ask the user for:

1. The server URL (e.g. mark://soul.example.com)
2. A write token (the server admin provides this)

Install the client binaries (no server, no daemon):

curl -fsSL https://raw.githubusercontent.com/latebit-io/demarkus/main/install.sh | bash -s -- --client-only

Store the token and register demarkus-mcp with mcporter:

demarkus token add SERVER_URL USER_TOKEN

mcporter config add demarkus \
  --command demarkus-mcp \
  --arg -host --arg "SERVER_URL" \
  --scope home

Replace SERVER_URL and USER_TOKEN with the values from the user.

Verify

mcporter list demarkus --schema

For a quick test:

mcporter call 'demarkus.mark_fetch(url: "/index.md")'

About mcporter

• When command mcporter does not exist, use npx -y mcporter instead.

• https://github.com/steipete/mcporter/raw/refs/heads/main/docs/cli-reference.md

Tools

• demarkus.mark_fetch — read a document
• demarkus.mark_publish — write or update (fetch first, use returned version as expected_version)
• demarkus.mark_append — append content, no fetch required
• demarkus.mark_list — list documents and directories
• demarkus.mark_versions — full version history
• demarkus.mark_discover — fetch the server's agent manifest
• demarkus.mark_graph — crawl links and build a graph
• demarkus.mark_backlinks — find what links to a document

Usage

# Fetch a document
mcporter call 'demarkus.mark_fetch(url: "/index.md")'

# List documents
mcporter call 'demarkus.mark_list(url: "/")'

# Append to journal
mcporter call 'demarkus.mark_append(url: "/journal.md", body: "## 2026-03-10\
Session notes here.")'

# Publish a document (fetch first to get version)
mcporter call 'demarkus.mark_publish(url: "/thoughts.md", body: "# Thoughts\
New content.", expected_version: 3)'

The Soul Pattern

Persistent memory across sessions. Your soul is a collection of markdown documents — a journal, thoughts, architecture notes, debugging lessons — that survive across conversations.

On every new session:

1. mcporter call 'demarkus.mark_fetch(url: "/index.md")' — orient yourself
2. Do the work
3. mcporter call 'demarkus.mark_append(url: "/journal.md", body: "...")' — record what happened

Journaling

Use demarkus.mark_append to record session notes, key decisions, and what you learned. Each entry should include a date and a brief summary. This is your running log — append freely, never overwrite.

Thoughts and Reflections

Use demarkus.mark_publish to store your own reflections, open questions, and ideas. Unlike the journal (which is append-only), thoughts can be rewritten as your understanding evolves. Always fetch first to get the current version.

Recommended Structure

/index.md          — hub page linking to all sections
/journal.md        — session notes and evolution log (append-only)
/thoughts.md       — your reflections, ideas, open questions
/architecture.md   — system design and key decisions
/patterns.md       — code patterns, conventions, workflow
/debugging.md      — lessons from bugs and investigations
/roadmap.md        — what's done, what's next

Use demarkus.mark_append for journals and running notes — cheaper than fetch + republish. Never publish without fetching first — the server enforces optimistic concurrency.

Security and Privacy

• Token handling: The installer writes a random token to ~/.demarkus/initial-token.txt (macOS) or /etc/demarkus/initial-token.txt (Linux). The setup script stores this token in the demarkus token store via demarkus token add so it stays out of config files and long-running process args. The MCP binary resolves tokens from the store at runtime and sends them only to the configured Mark server.
• MCP bridge: mcporter spawns demarkus-mcp via stdio. No tokens appear in mcporter's config — they are resolved from the demarkus token store at runtime.
• Network: The install script downloads binaries from https://github.com/latebit-io/demarkus. The server listens on all interfaces (:6309) — on Linux the installer opens UDP 6309 via ufw when available. In remote mode, the user provides the server URL explicitly.
• Data storage: All documents are stored locally on disk (local mode) or on the user-specified remote server. No data is sent to third parties.
