For agents — source-of-truth: This skill is authored in roboflow/computer-vision-skills and shipped with the Roboflow plugin. If your client has loaded the plugin (you'll see roboflow:<name> skills in your available skills list), use those local skills — they're read fresh from disk every session. The same content served as MCP resources at roboflow://skills/<name>/... is a fallback for clients without the plugin and may lag this repo. Don't call ReadMcpResourceTool for roboflow://skills/... URIs when a local roboflow:<name> skill is available.

Roboflow Universe

Open repository of 1M+ computer vision datasets and 50K+ pre-trained models at universe.roboflow.com.

URL Patterns

Page URL Content
Home universe.roboflow.com Search, trending projects, categories
Project universe.roboflow.com/{owner}/{project} Overview, classes, metrics, license, fork
Images universe.roboflow.com/{owner}/{project}/browse Browse images with annotations
Dataset version universe.roboflow.com/{owner}/{project}/dataset/{version} Version details, splits, download
Model universe.roboflow.com/{owner}/{project}/model/{version} Try model, metrics, deploy snippet

Searching Universe

MCP app (universe_search_app)

Use when someone must choose a dataset after seeing it: previews, classes, license, image counts, etc. Pure MCP JSON hits from universe_search are not a substitute for that UX — open the app when the decision needs eyes on the listings.

MCP Tool

Use universe_search to find datasets/models programmatically. Pass a descriptive query (e.g. "hard hat detection construction site").

Web Search

Search is hybrid — combines semantic similarity with keyword matching. Use specific, descriptive queries for best results.

Query Operators

All operators can be mixed with free-text: fire smoke class:fire,smoke images>200 model

Operator Example Effect
model waste detection model Only datasets with a trained model
object detection helmet object detection Filter by project type (also: classification, instance segmentation, keypoint detection)
class:X class:helmet,person Must contain these classes
tag:X tag:safety Filter by Universe tag
model:X model:yolov8 Filter by trained model architecture
images>N images>500 Min image count (also >=, <, <=, =)
stars>=N stars>=5 Min star count
views>N views>1000 Min view count
downloads>N downloads>100 Min download count
updated:Nd updated:30d Updated within N days (also h, w, mo, y)
sort:X sort:stars Sort by field (stars, images, updated, downloads, views)
like:dataset-url like:coco Find similar datasets

Tips for Effective Queries

  • Combine free-text with operators: pothole road damage class:pothole images>100 sort:stars
  • Add model to only get inference-ready datasets
  • Include project type keywords to filter: helmet instance segmentation
  • Use class: when you know exactly what classes you need
  • Use specific object names, not generic terms ("forklift in warehouse" > "vehicle")

Evaluating a Dataset

Before forking, check these signals:

Criterion Where to Look Good Sign
Class coverage Classes list on project page All your target classes present
Image count Project overview 500+ images per class for detection
Annotation quality Browse > click individual images Tight bounding boxes, consistent labels
Class balance Project overview / health No extreme class imbalance
Image diversity Browse images Varied lighting, angles, backgrounds
License "Cite this Project" section Compatible with your use case (see below)
Model metrics Model tab (if available) mAP > 70% suggests decent annotations

Licenses

Found in the "Cite this Project" section on the project page. No license listed = all rights reserved.

License Commercial Use Modify Attribution Required
Public Domain Yes Yes No
CC BY 4.0 Yes Yes Yes
MIT Yes Yes Yes (in license copy)

Forking a Dataset

Fork = copy a Universe dataset into your workspace (no download/re-upload needed).

  1. Open dataset on Universe
  2. Click Download Dataset button
  3. Choose Train a model with this dataset (full fork) or Train from a portion of this dataset (partial clone)
  4. Dataset copies into your workspace

After forking you can: rename classes, add/remove images, generate versions, train models.

Requires: Logged-in Roboflow account.

Downloading a Dataset

For local/notebook training instead of Roboflow cloud training.

Method When to Use
Train a model with this dataset (fork) Training on Roboflow, want full data in workspace
Train from a portion (clone) Want a subset or to combine with other data
Download dataset Local training via code snippet or ZIP file

Supports all standard export formats (COCO, YOLO, VOC, CreateML, TFRecord, etc.).

Path: Project page > Download Dataset button > choose method.

Using a Universe Model

Direct Inference via Workflows

  1. Create a Workflow in Roboflow
  2. Add a model block
  3. Switch to Public Models tab
  4. Paste the model ID from the Universe model page (copy icon at top)
  5. Click Use model ID

Model ID format: {owner}/{project}/{version} (shown on Universe model page).

Checkpoint Training

Fork the dataset, then train your own model using the forked data. Use a Universe model's architecture as a starting point via Roboflow Train.

Inference Metrics (shown on model page)

Project Type Metrics Shown
Object Detection mAP, precision, recall
Classification Accuracy
Segmentation mAP, precision, recall

MCP Tool Reference

universe_search — Search Universe for datasets/models.

Param Type Default Notes
query str (required) Search query text
result_type "dataset" | "model" | null null Filter by result type
limit int 12 Max results per page
page int 1 Page number (1-indexed)

Returns: name, url, type, classes, classCount, images, description, tags, license, stars, views, downloads, modelCount, latestVersion.
