Perplexity

Validate DeepOpinion model lists at runtime

The `list_models` tool queries your DeepOpinion account, and the framework validates the returned metadata against strict Python types. Working with dynamic model lists can introduce bugs if an API changes. If the server returns a field that doesn't match your schema, the framework fails immediately, preventing your agent from attempting to use a broken model ID.

Get type-safe text predictions using this MCP Server

When your agent calls the `predict` tool, the framework inspects the prediction payload and parses it into a strongly-typed model. This eliminates silent data corruption in your production pipeline. Your code can confidently use the classification labels and confidence scores, knowing they have been validated at runtime.

Run batch predictions with strict schema enforcement

Running batch predictions with the `predict_batch` tool requires reliable data handling that the framework validates at runtime. If any item in the batch fails validation, the agent raises a clear error. This guarantees that only clean, structured text data enters your downstream databases and analytics dashboards.

Setup guide

Set up DeepOpinion (No-code NLP & Text AI API) MCP in Pydantic AI

Prerequisites

Python 3.10+ installed
pydantic-ai-slim[fastmcp] package
Active Vinkius subscription with a valid endpoint token

1

Install Pydantic AI with FastMCP
Run pip install "pydantic-ai-slim[fastmcp]". The FastMCP toolset replaces the deprecated MCPServerHTTP class with full protocol support.
2

Configure the FastMCPToolset
Pass a JSON-style config dict to FastMCPToolset with your Vinkius URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports Streamable HTTP, SSE, and Stdio transports.
3

Create and run your agent
Pass the toolset to Agent(toolsets=[toolset]) and call agent.run(). Swap openai:gpt-4o for any supported model — Anthropic, Google, Mistral, or Groq.

agent.py

from pydantic_ai import Agent
from pydantic_ai.toolsets.fastmcp import FastMCPToolset

toolset = FastMCPToolset({
    "mcpServers": {
        "deepopinion-no-code-nlp-text-ai-api-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to DeepOpinion (No-code NLP & Text AI API) tools.",
)

result = await agent.run("List recent DeepOpinion (No-code NLP & Text AI API) transactions")
print(result.output)

Common questions about DeepOpinion (No-code NLP & Text AI API) MCP in Pydantic AI

Install the framework with the mcp extra, then instantiate the MCPToolset with your Vinkius HTTP URL. Pass the toolset directly to your Agent constructor to expose the NLP tools.

Yes, it does. The framework intercepts the raw JSON responses from predict and predict_batch and validates them against your defined Pydantic models before your agent can use the data.

Yes, because the framework is model-agnostic. You can connect your MCP Server to agents running on Anthropic Claude, Gemini, or even local models while maintaining full type safety.

The framework supports both Streamable HTTP and SSE transports. Since Vinkius hosts the server externally, you will use the HTTP transport to connect your local agent.

Your text inputs and classification outputs are processed inside a secure, ephemeral V8 Isolate sandbox. The server does not write any text to disk, and all communication uses secure HTTPS channels.
