Fiftyone tools (18, 1 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • clear_view

    Clears the current view from the session, showing all samples.

  • close_app

    Closes the active FiftyOne App session and stops the server.

  • dataset_summary

    Get detailed summary statistics and metadata for a dataset

  • disable_plugin

    Disables a FiftyOne plugin, removing its operators from availability.

  • download_plugin

    Downloads and installs a FiftyOne plugin from GitHub. Plugins immediately add new operators to the system (accessible via list_operators and execute_operator). Common repo: 'voxel51/fiftyone-plugins' contains all official plugins. After installation, use enable_plugin to activate the plugin's operators.

  • enable_plugin

    Enables a downloaded FiftyOne plugin, making its operators immediately available through list_operators and execute_operator. Required after download_plugin to activate the plugin's functionality.

  • execute_operatorwrite action

    Execute any FiftyOne operator with the current execution context. This provides access to 80+ operators from the plugin ecosystem. WORKFLOW: (1) Call list_operators to discover available operators, (2) Call get_operator_schema to see required parameters, (3) Call execute_operator with the operator URI and params. Common examples: '@voxel51/brain/compute_similarity' for image similarity, '@voxel51/

  • get_context

    Get the current execution context state including dataset, view, and selection information.

  • get_operator_schema

    Get the dynamic input schema for a specific operator. Schemas are context-aware and change based on the current dataset/view/selection. Use this AFTER list_operators to understand what parameters an operator accepts. Requires context to be set via set_context first.

  • get_plugin_info

    Gets detailed information about a specific FiftyOne plugin including its operators, version, and metadata.

  • get_session_info

    Gets information about the current FiftyOne App session, including whether it's active and what dataset is loaded.

  • launch_app

    Launches the FiftyOne App server. Required for executing delegated operators that need background execution (e.g., brain operators like find_near_duplicates).

  • list_datasets

    List all available FiftyOne datasets with metadata

  • list_operators

    Discover all available FiftyOne operators (80+ built-in operators from plugins). Returns operators from installed plugins including: @voxel51/operators (50+ core operators like tag_samples, clone_samples), @voxel51/brain (similarity, duplicates, visualization), @voxel51/utils (create_dataset, delete_dataset, clone_dataset), @voxel51/io (import/export), @voxel51/evaluation, @voxel51/annotation, @vo

  • list_plugins

    Lists available FiftyOne plugins and their operators. Plugins extend functionality by providing additional operators. Key plugins: @voxel51/brain (16 operators for similarity/duplicates/visualization), @voxel51/utils (12 operators for dataset CRUD), @voxel51/io (5 operators for import/export), @voxel51/evaluation (5 operators), @voxel51/annotation (6 operators), @voxel51/zoo (2 operators). Use thi

  • load_dataset

    Load a FiftyOne dataset by name and return basic information

  • set_context

    Set the execution context for FiftyOne operators. REQUIRED before executing operators or getting schemas. This defines what dataset, view, and selection subsequent operators will work with. The context persists across multiple operator executions until changed.

  • set_view

    Sets a filtered view in the FiftyOne App. Use this to filter samples by field values, tags, existence of fields, or load saved views. The view updates immediately in the App UI.

What is the FiftyOne MCP Server?

Enable Agents to explore datasets, execute operators, and control the FiftyOne App through natural language. This server exposes 45+ MCP tools across data operations, App UI control, and the full operator/plugin ecosystem.

"List all my datasets"
"Load quickstart dataset and show summary"
"Find similar images in my dataset"

The server starts with 50 built-in operators. Install plugins to expand functionality - the AI can discover and install plugins automatically when needed (brain, zoo, annotation, evaluation, and more).
