videre-mcp 0.2.0

MCP server that bridges vision models to text-only coding models using Florence-2

videre-mcp

MCP server that bridges vision models to text-only coding models using Florence-2.

Non-vision LLMs can't see images — videre-mcp fixes that. It loads a Florence-2 vision model locally and exposes four MCP tools that convert images (including SVGs) and screenshots into structured text descriptions that any text-based model can consume.

Screenshot tool → videre-mcp (Florence-2) → Text description → Coding model

Installation

pip install videre-mcp

Or with uv:

uv pip install videre-mcp

Requires Python 3.11+ and ~300MB disk space for the Florence-2-base model weights (downloaded automatically on first use).

Usage

Add to your OpenCode configuration:

{
  "mcpServers": {
    "videre-mcp": {
      "command": "videre-mcp"
    }
  }
}

Or run directly:

videre-mcp
# or
python -m videre_mcp

Tools

describe_image

Generate a natural language description of an image.

Parameters:

• image_path (str) — Path to the image file (supports PNG, JPEG, SVG)
• detail_level (str, optional) — "normal" (default) for brief caption, "high" for detailed description

Example:

result = describe_image("/path/to/photo.png", detail_level="high")
# Returns:
# {
#   "description": "A sunlit meadow with wildflowers in bloom...",
#   "model": "Florence-2-base",
#   "prompt_used": "<MORE_DETAILED_CAPTION>"
# }

ocr_image

Extract text from an image using optical character recognition.

Parameters:

• image_path (str) — Path to the image file (supports PNG, JPEG, SVG)
• detail_level (str, optional) — "normal" (default) for plain text, "high" for text with bounding regions

Example:

result = ocr_image("/path/to/document.png", detail_level="high")
# Returns:
# {
#   "text": "Invoice Number 12345",
#   "regions": [
#     {"label": "Invoice Number 12345", "bbox": [10, 20, 30, 40, 50, 60, 70, 80]}
#   ]
# }

describe_screenshot

Describe UI regions in a screenshot — designed for coding agents that need to understand screen layouts.

Parameters:

• image_path (str) — Path to the screenshot file (supports PNG, JPEG, SVG)
• detail_level (str, optional) — "normal" (default) for dense region captions, "high" for per-region descriptions

Example:

result = describe_screenshot("/path/to/screenshot.png")
# Returns:
# {
#   "regions": [
#     {"bbox": [10, 20, 30, 40], "label": "search bar"},
#     {"bbox": [100, 200, 300, 250], "label": "submit button"}
#   ],
#   "model": "Florence-2-base"
# }

take_screenshot

Capture a screenshot and optionally describe it using Florence-2. Supports multi-monitor setups via the monitor parameter.

Parameters:

• output_path (str, optional) — Path to save the screenshot PNG. If None, saves to a temp file.
• monitor (int, optional) — Monitor index: 0 = all monitors combined, 1 = primary, etc. (default: 0)
• describe (bool, optional) — If True, also run describe_screenshot on the captured image (default: True)

Example:

result = take_screenshot(monitor=1, describe=True)
# Returns:
# {
#   "path": "/tmp/tmpxxxxxx.png",
#   "width": 1920,
#   "height": 1080,
#   "monitor": 1,
#   "regions": [
#     {"label": "search bar", "bbox": [10, 20, 30, 40]},
#     ...
#   ]
# }

Supported Formats

Format	Support
PNG	✅ Native
JPEG	✅ Native
SVG	✅ Via cairosvg rasterization

Requirements

• Python 3.11+
• ~300MB disk for model weights (auto-downloaded on first inference)
• Works on CPU; GPU (CUDA) is auto-detected and used if available

Continuous Integration

The Florence-2 slow tests (real model load + inference) run on a nightly schedule via GitHub Actions. See .github/workflows/slow-tests.yml.
