Bolor Brain

Pure intelligence for Claude Code. Reasoning, memory, and learning -- nothing else.

What Is This?

Bolor Brain is an MCP server that gives Claude Code a brain: structured reasoning, persistent memory, and learning from experience.

User --> Claude Code (Gateway + Executor)
              |
         +----+----+
    Bolor Brain   NSAF
      (MCP)       (MCP)
      THINK       EVOLVE

• Claude Code = Gateway + tool execution + sessions + permissions
• Bolor Brain = Reasoning engines + memory + learning + persistence
• NSAF = Strategy evolution + self-improvement (separate MCP server)

Bolor Brain does NOT execute anything. No file ops, no scheduling, no autonomous loop. Claude Code already does all of that. Bolor Brain only thinks.

Quick Start

1. Install

git clone https://github.com/photoxpedia/bolor-brain-mcp.git
cd bolor-brain-mcp
pip install -e .

2. Configure Claude Code

Add to ~/.claude/mcp-config.json:

{
  "mcpServers": {
    "bolor-brain": {
      "command": "python",
      "args": ["-m", "mcp_server"],
      "cwd": "/path/to/bolor-brain-mcp"
    }
  }
}

3. Use

/reason Why is Python popular for data science?
/debug API returns 500 errors under load
/decide PostgreSQL or MongoDB for our app?
/learn-from We fixed the memory leak by increasing connection pool

MCP Tools (11)

Reasoning (6)

Tool	What It Does
reason_hybrid	Auto-selects best reasoning approach for any query
reason_symbolic	Forward/backward chaining with facts and rules
reason_knowledge_graph	Graph traversal, path finding, relationship exploration
reason_case_based	Find similar past problems and their solutions
reason_hypothesis	Generate and test hypotheses from observations
reason_analogical	Cross-domain pattern transfer (atom ~ solar system)

Memory (4)

Tool	What It Does
remember	Store a case, fact, node, or edge
recall	Retrieve matching cases or facts
learn	Store problem/solution/outcome (shortcut for remember)
forget	Delete a case or fact by ID

Utility (1)

Tool	What It Does
brain_stats	Cases, facts, nodes, edges count

---

Skills (6)

Skill	When To Use
/reason	Deep analysis of any complex problem
/debug	Systematic bug hunting with hypothesis testing
/decide	Evidence-based technical decisions
/learn-from	Store experiences for future use
/nsaf	NSAF evolution integration (requires NSAF MCP)
/orchestrate	Meta-orchestration combining Bolor Brain + NSAF

---

Persistence

Brain state persists to ~/.bolor-brain/ as JSON:

~/.bolor-brain/
  cases.json       # Problem -> solution -> outcome
  facts.json       # Symbolic reasoning facts
  knowledge.json   # Knowledge graph (nodes + edges)

Knowledge compounds over time. Solve a bug once, recall the solution instantly next time.

With NSAF

Add NSAF to get evolution capabilities:

{
  "mcpServers": {
    "bolor-brain": {
      "command": "python",
      "args": ["-m", "mcp_server"],
      "cwd": "/path/to/bolor-brain-mcp"
    },
    "nsaf": {
      "command": "python3",
      "args": ["nsaf_mcp_server.py"],
      "cwd": "/path/to/nsaf",
      "env": { "PYTHONPATH": "/path/to/nsaf" }
    }
  }
}

Together: Bolor Brain reasons about WHAT to do. NSAF evolves HOW to do it better. Claude Code executes.

See skills/nsaf.md and skills/orchestrate.md for combined workflows.
