Orlog — Decision Reasoning Engine

Orlog MCP Server

Multi-perspective decision reasoning for Claude. When you're facing a real choice — career, money, relationships, strategy — Orlog examines the competing angles and takes a clear position, not a hedge.

What it does

Two tools Claude can call:

Tool	When Claude uses it
orlog_decide	User has a clear decision with real tension
orlog_explore	User is stuck or unsure what they're actually deciding

Orlog doesn't hedge. It reasons through competing angles — what each side actually costs, what's really at stake, what the person is avoiding saying — and takes a position.

Install

Step 1 — Get an API key

Sign up at orlog.fyi and get your key from the Developers page.

Step 2 — Add to Claude config

For Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json on Mac, %APPDATA%\Claude\claude_desktop_config.json on Windows):

{
  "mcpServers": {
    "orlog": {
      "type": "sse",
      "url": "https://tomsem77--mimir-mcp-serve.modal.run/sse",
      "headers": {
        "X-API-Key": "your-api-key-here"
      }
    }
  }
}

For Claude Code (add to your project or global .claude/settings.json):

{
  "mcpServers": {
    "orlog": {
      "type": "sse",
      "url": "https://tomsem77--mimir-mcp-serve.modal.run/sse",
      "headers": {
        "X-API-Key": "your-api-key-here"
      }
    }
  }
}

Step 3 — Restart Claude

Orlog appears automatically. Claude will call it when you bring a real decision.

---

Usage

You don't need to invoke Orlog manually. Just talk to Claude. When the conversation surfaces a real decision, Claude calls orlog_decide or orlog_explore automatically.

Or prompt it directly:

"Use Orlog to help me think through whether to take this job offer."

About

Orlog is built on Mimir — a fine-tuned reasoning model trained specifically on decision quality, not general knowledge. The reasoning framework draws from multiple deliberative perspectives to surface what's actually at stake before taking a position.
