Built on the Model Context Protocol (MCP) for Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This connection provides 19 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.
Manual data preparation kills momentum.
Think about it: You get a client PDF. First, you have to download it and open it in Acrobat. Then, you copy the text into Notion, paste it into an analysis tool, and manually highlight sections you want analyzed. If it's audio, you record it, then use another service just to transcribe the speech before you can even start summarizing.
With this MCP, your agent handles all that friction. You upload the file once, and the system automatically prepares everything—it extracts the text, finds key data points with `extract_entity`, and gives you a clean summary without any copy-pasting or switching tabs. The result is immediate, structured output.
Structured knowledge retrieval via embeddings
Before this MCP, finding related information meant keyword matching—a simple search that only worked if the user remembered the exact right word. If the document used synonyms or was poorly indexed, you failed.
Now, by running `generate_embeddings`, your system converts text into mathematical vectors. This means it finds documents based on *meaning* and *concept*, not just keywords. It's a massive difference for search accuracy.
What your AI can actually do with this
Think of this MCP as an entire MLOps stack that talks to your agent. Instead of just asking a large language model a question, you run a whole workflow. You feed it raw documents or audio, and the system handles all the prep work: transcribing files, extracting structured data points, and figuring out what's important enough to index for advanced search.
If you’re building anything that needs to be accurate, grounded in specific corporate knowledge, or highly specialized (like diagnosing niche medical texts), this is your kit. It lets you manage model versions and train models on proprietary datasets so the AI doesn't just guess—it knows your business rules. When connecting through Vinkius, it means all these deep data operations are accessible to any MCP-compatible client, letting you build complex logic without writing boilerplate API calls.
019e5d21-f4bb-72b3-a1a2-62ab4fb1276d Here's how it actually works
The bottom line is that your agent gains a dedicated MLOps pipeline, letting you move from raw documents to deployable AI features without leaving your chat interface.
Subscribe to this MCP and input your specific Gradient API Key and Workspace ID into your AI client.
Your agent gains access to the full suite of model management tools, allowing you to list foundational models or initiate a fine-tuning job.
You use the specialized functions—for example, running extract_entity on an uploaded file—and receive structured data outputs ready for application integration.
Who is this actually for?
This stack is built for technical teams who deal with proprietary data and require highly accurate, specialized AI. It's for the Data Scientists running complex research pipelines or the ML Engineers building production-grade LLM apps.
They use this MCP to quickly iterate on fine-tuning experiments and test model completions against new data sources.
They generate embeddings and perform NLP analysis—like running analyze_sentiment—without needing complex local server setups or multiple APIs.
They integrate advanced LLM capabilities into applications, using tools like create_rag_collection to ground answers in user-uploaded documents.
What Changes When You Connect
When you need to understand user feelings, use analyze_sentiment to instantly gauge the tone of feedback or communications.
Don't just ask for a summary; upload a PDF using upload_file, then use extract_pdf and summarize_document to get both text and key data points in one go.
Stop losing context. By generating embeddings with generate_embeddings, your agent can find relevant information across millions of documents, even if the keywords don't match.
Build specialized bots that speak your language. Use fine_tune_model to train a model on your specific documentation, making it an expert in your domain.
Manage knowledge with create_rag_collection. This process keeps your answers grounded in verifiable sources, minimizing hallucinations and improving trust.
See it in action
Customer Support Chatbot Build
A developer needs a chatbot that only answers questions based on the company's internal policy manuals. They use upload_file to ingest all PDFs, then call create_rag_collection. Finally, they let their agent ask questions using the collection, ensuring accurate, source-backed responses.
Legal Document Review
A paralegal needs to review dozens of contracts. They use extract_entity repeatedly on each document to pull out all dates, client names, and contract values into a single structured spreadsheet for quick comparison.
Market Research Analysis
A marketing team analyzes social media comments. They run analyze_sentiment on thousands of posts and then use summarize_document to quickly group the findings by topic, identifying both positive buzz and critical pain points.
Historical Data Indexing
A researcher has old archives. They first transcribe audio records using create_transcription, then use extract_entity on the resulting text to pull out names, dates, and locations for a searchable database.
The honest tradeoffs
Asking the model directly about proprietary data
The user simply pastes a chunk of internal code into the chat and asks, 'What does this mean?' The LLM answers using general knowledge, ignoring company-specific context.
Instead, first upload the file using upload_file, then use create_rag_collection to index it. Finally, ask your agent questions that reference the collection; the answer will be grounded in the document.
Treating embeddings like answers
The developer assumes running generate_embeddings is enough. They see a list of numbers and think they have actionable insights, but the output is meaningless to an end-user.
Use generate_embeddings to find similar documents, then pass those retrieved documents into a tool like answer_question. The embeddings help find the data; the tools use it.
Forgetting to structure input files
Trying to run complex analysis on raw, un-uploaded text that might contain mixed formats (images, tables, text). The tool will fail or only process simple strings.
Always start by using upload_file to ingest the source material. If it's a PDF, use extract_pdf; if it's audio, use create_transcription before any other analysis.
When It Fits, When It Doesn't
Use this MCP if your AI project requires more than just talking to an LLM; it needs data plumbing. If you are building a system that must interpret PDFs, analyze sentiment at scale, or answer questions based on documents the model has never seen before, this is for you. You absolutely need generate_embeddings and RAG capabilities (create_rag_collection). Don't use this if your goal is simple text generation—just running complete_model might be enough. If all you need is to chat with a large language model about general topics, you don't need the complexity of fine-tuning or document extraction.
Questions you might have
How do I use the `analyze_sentiment` tool? +
You run it by providing the text or document you want checked. The tool returns a specific sentiment classification (positive, negative, neutral) and a confidence score for that rating.
What is the difference between `summarize_document` and `answer_question`? +
Summarize_document creates an overview of everything in a file. Answer_question narrows the focus, giving you a direct answer to one specific query based on that same source document.
How do I begin building with RAG using `create_rag_collection`? +
Start by uploading all your foundational documents. Then call create_rag_collection, which indexes those files, making them available for retrieval-augmented questioning.
Can I use `extract_entity` on PDFs? +
Yes. You first need to run extract_pdf on the file to get the raw text and data out of the document format, which then feeds into extract_entity for structured parsing.
Do I need to use `list_models` before running `fine_tune_model`? +
It's good practice. Use list_models first to confirm the foundational model ID you want to base your training on, ensuring you select the correct starting point.
When I use `upload_file`, what file formats does it support for processing? +
It handles a wide variety of files, including PDFs, images, and raw documents. After the upload completes, you must pass the resulting unique file ID to another tool like extract_entity or answer_question so it knows which data source to reference.
How does using `create_model` affect my API usage quotas? +
Creating a model reserves the infrastructure and associated weights for your custom instance. The act of creation itself doesn't consume run-time quota, but subsequent calls to that model will count toward your usage limits.
If I no longer need an instance, how does the `delete_model` tool work? +
The delete_model tool permanently removes the fine-tuned model and its weights from your workspace. Use this when you are sure the model is obsolete; running it is irreversible.
How can I start training a custom model with my own data? +
You can use the fine_tune_model tool. Simply provide the model ID and an array of training samples. The agent will handle the submission to Gradient's training infrastructure.
Can I use RAG (Retrieval Augmented Generation) with this server? +
Yes! The complete_model tool includes an optional rag parameter, allowing you to provide context or collection IDs to ground the model's responses in specific data.
How do I generate vector embeddings for my documents? +
Use the generate_embeddings tool by specifying a model slug (like 'bge-large') and a list of text inputs. It will return the high-dimensional vectors for your text.
