Photographi MCP Server

photographi-mcp

Fast, private, and grounded technical photo analysis for AI applications.

photographi-mcp is an MCP server that enables AI models and LLM-powered tools to perform technical analysis on local photo libraries. It runs computer vision models directly on your hardware (powered by photo-quality-analyzer-core) to evaluate sharpness, focus, and exposure—enabling capabilities like automated culling, burst ranking, and metadata indexing without requiring a cloud upload.

⚡ Why photographi?

• Technical First: Purpose-built for objective metrics (sharpness, lighting, focus). It provides technical data for evaluating image quality.
• Token Efficient: Save model context by pre-filtering technical metadata locally. Only the most relevant insights are sent to the AI application, keeping sessions fast and lean.
• Privacy First: All analysis happens 100% locally on your machine.
• Low Latency: Built for efficient processing, allowing for rapid ranking and technical feedback on local photo folders.

👁️ What It Analyzes

• Smart Focus: Detects subjects and verifies they're sharp
• Exposure: Catches blown highlights and blocked shadows
• Gear-Aware: Knows your lens's sweet spot for optimal sharpness
• Composition: Evaluates framing and subject placement
• Quality Alerts: Flags motion blur, diffraction, high ISO noise

[!NOTE] Technical vs. Artistic: This tool is strictly objective. It evaluates photos based on technical metrics and computer vision (sharpness, exposure, noise, etc.). It does not understand artistic intent, aesthetics, or "vibe." A blurry, underexposed photo may be an artistic masterpiece, but photographi will correctly flag it as technically poor.

For the science and math behind it, see the Technical Documentation.

📸 See It In Action

Here are real examples from actual photo analysis:

Example 1: Excellent Photo

{
  "overallConfidence": 0.89,
  "judgement": "Excellent",
  "keyMetrics": {
    "sharpness": 0.94,
    "exposure": 0.87,
    "composition": 0.85
  }
}

Verdict: Tack sharp on subject, well exposed, strong composition.

---

Example 2: Poor Photo

{
  "overallConfidence": 0.20,
  "judgement": "Very Poor",
  "keyMetrics": {
    "sharpness": 0.30,
    "focus": 0.07,
    "exposure": 0.0
  }
}

Verdict: Missed focus on subject, severe underexposure/black clipping, and excessive headroom.
