laeka-brain 0.2.1

MCP server — Laeka Brain cognitive layer for Claude Code

laeka-brain

A cognitive layer for the AI you already use.

This MCP server connects your Claude Code environment to Laeka Brain — the OmniQ protocol made available through six tools. It is a context provider. It does not call an LLM. It does not store your conversations. It returns context that Claude uses natively.

What it is

Six tools, added to Claude Code via a single entry in ~/.claude/.mcp.json:

• query — ask what Laeka Brain says about a concept or question
• reflect — share a situation; Brain holds the mirror and asks the question you haven't asked yourself
• consolidate — save a session insight to your personal mini-brain
• recall — semantic search across your personal mini-brain — find patterns and insights by natural language query
• list_brain_skills — browse the skill marketplace of an auxiliary brain (default: laeka-code)
• get_brain_skill — retrieve and apply a specific skill by name (e.g. systematic-debugging, verification-before-completion)

The four OmniQ lenses — MONADE, SYMBIOTE, ARCHITECT, EMPATH — operate through all six tools. You will feel them before you name them.

v0.2.1 — X-User-UUID header on brain skills calls

v0.2.1 passes the X-User-UUID header on list_brain_skills and get_brain_skill calls for tier-gated access compatibility. Users on paid tiers no longer receive 403 when accessing auxiliary brain skills.

v0.2.0 — brain skills marketplace

v0.2.0 adds two new tools (list_brain_skills, get_brain_skill) that expose the Laeka Code skill marketplace — 28 rebranded engineering protocols available directly in Claude Code. Query, list, and apply skills from auxiliary brains like Laeka Code.

How to install

Requirements: Python 3.12+, Claude Code.

pip install laeka-brain

Or without installing permanently:

uvx laeka-brain

---

How to configure

Add this to ~/.claude/.mcp.json:

{
  "mcpServers": {
    "laeka-brain": {
      "command": "laeka-brain",
      "env": {
        "LAEKA_BRAIN_API_URL": "http://172.105.0.134:8822"
      }
    }
  }
}

If you installed via uvx, replace "command" with "uvx laeka-brain" or use the full uvx path.

Environment variables:

Variable	Default	Description
LAEKA_BRAIN_API_URL	http://172.105.0.134:8822	Seahorse API base URL
XDG_CONFIG_HOME	~/.config	Override config dir location

Your user_uuid is generated on first run and stored at ~/.config/laeka-brain/user_uuid. It is the key to your personal mini-brain. Keep it — it cannot be recovered if lost.

The 4 tools

query

Ask what Laeka Brain says about something.

Use query with question="What does the ARCHITECT lens say about naming things in code?"

Returns the canonical Brain context framed around your question. Claude uses it as a cognitive lens — no LLM call happens inside this server.

reflect

Share a situation. Brain holds the mirror.

Use reflect with situation="I've rewritten this module three times and I still don't like it."

Returns the canonical context plus a mirror directive. Claude applies the four lenses and asks the question that helps you see what you're not seeing. No advice. Just the mirror.

consolidate

Persist a session insight to your mini-brain.

Use consolidate with text="Discovered that my naming friction is really a module boundary problem."

Stores the text as a pattern_observation in your personal memory cell. If your mini-brain doesn't exist yet, it is provisioned automatically.

recall

Semantic search across your personal mini-brain.

Use recall with query="What did I learn about naming last week?"

Searches your stored patterns using vector similarity and returns the top matches ranked by relevance score. Each result shows the text snippet (up to 200 chars), sector, doc type, and creation date.

If the search endpoint is not yet available, returns your chunk count as a fallback so you always know where you stand.

How to leave

If you want to remove Laeka Brain from your environment:

1. Remove the laeka-brain entry from ~/.claude/.mcp.json.
2. Delete your local config: rm -rf ~/.config/laeka-brain
3. Optionally, destroy your mini-brain on the server:

curl -X POST http://172.105.0.134:8822/v1/brain/mini/offboard \
  -H "Content-Type: application/json" \
  -d "{\"user_uuid\": \"$(cat ~/.config/laeka-brain/user_uuid)\", \"confirm\": true}"

This destroys your private chunks permanently. Patterns that were anonymized and contributed to the collective remain as collective learning — they are not yours anymore, and they are not reversible.

No cron jobs. No daemons. No leftover files beyond ~/.config/laeka-brain/ (which you just deleted).

Built with gratitude for Anthropic's foundational work. Laeka Brain is an extension that amplifies Claude Code — not a competitor, not a replacement.
