What is the Nyckel ML MCP Server?
Connect your Nyckel machine learning account to your AI agent and leverage powerful automated classification and semantic search through natural conversation.
What you can do
- Automated Classification — Send text or image URLs to your trained ML functions to get instant predictions and confidence scores.
- Semantic Search — Query your search function galleries to find semantically similar samples based on input data.
- Function Management — List all ML functions in your account and retrieve detailed configuration and metadata.
- Training Oversight — Access the data samples used to train your functions and monitor assigned labels.
- Sample Annotation — Upload new training samples and manually assign or update classification labels.
- Label Discovery — Retrieve the set of all available labels and categories defined for your ML models.
- Account Insights — Access profile and workspace metadata for your authenticated Nyckel account.
How it works
- Subscribe to this server
- Enter your Nyckel Client ID and Client Secret
- Start processing data with AI from Claude, Cursor, or any MCP client
Who is this for?
- AI Developers — quickly test classification models or search galleries without writing custom integration code.
- Data Scientists — monitor training samples and prediction accuracy directly from your workspace.
- Content Moderators — automate the classification of user-generated content using custom-trained ML functions.

Why Cursor?
Cursor's Agent mode turns Nyckel ML into an in-editor superpower. Ask Cursor to generate code using live data from Nyckel ML and it fetches, processes, and writes. all in a single agentic loop. 10 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.
- —
Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context
- —
Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards
- —
MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment
- —
VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

Frequently asked questions
How do I get my Nyckel credentials?
Log in to your Nyckel dashboard, navigate to your profile or settings, and look for the 'API Keys' section to find your Client ID and Client Secret.
Does this support image classification?
Yes! You can pass a publicly accessible image URL to the invoke_ml_function or semantic_search tools to classify or search based on visual content.
How accurate are the predictions?
Accuracy depends on the quality and quantity of training samples provided to your Nyckel function. The invoke_ml_function tool returns a confidence score for each prediction.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
Server shows as disconnected
Check Settings → Features → MCP and verify the server status. Try clicking the refresh button.
