Type-safe voice transcription for Pydantic AI

`speech_to_text` converts audio files into text strings with rigorous runtime type checking. When your Pydantic AI agent calls this tool, the framework validates the iFLYTEK transcription output against strict Python schemas before continuing. If the iFLYTEK API returns an unexpected data format, the Pydantic AI framework raises a validation error immediately. This prevents malformed transcripts from corrupting your application state or causing downstream logic failures.

Structured keyword extraction via this MCP Server

`keyword_extraction` parses text blocks and returns a list of high-value terms. This MCP Server makes it easy for your Pydantic AI agents to analyze articles, feedback, or chat logs and get validated Python lists in return. Your Pydantic AI agent can feed these keywords directly into other typed tools. Because every step is validated, you don't have to write manual parsing code to handle missing fields or bad types.

Convert text to speech with verified outputs

`text_to_speech` synthesizes audio files from your agent's text responses. Pydantic AI validates the resulting audio path or binary payload, ensuring your application always receives a valid file reference. You can pair this with `translate` to build a type-safe iFLYTEK localization engine. The Pydantic AI agent translates the text, validates the output schema, and then synthesizes the voice, keeping the entire pipeline completely safe.

Setup guide

Set up iFLYTEK Open Platform / 讯飞开放平台 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": {
        "iflytek-open-platform-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to iFLYTEK Open Platform / 讯飞开放平台 tools.",
)

result = await agent.run("List recent iFLYTEK Open Platform / 讯飞开放平台 transactions")
print(result.output)

Common questions about iFLYTEK Open Platform / 讯飞开放平台 MCP in Pydantic AI

Initialize an `MCPToolset` with the server's HTTP URL. Pass this toolset instance inside the `toolsets` argument when defining your Pydantic AI `Agent`.

Yes, this server supports both SSE and Streamable HTTP transports. You can configure your Pydantic AI `MCPToolset` to connect using either protocol depending on your network topology.

If the tool returns data that violates your Pydantic model, the framework throws a validation error. You can catch this exception in your Pydantic AI agent loop and instruct the model to correct its input parameters.

The server is completely model-agnostic. You can use it with OpenAI, Anthropic, Gemini, or even a local Ollama instance running through Pydantic AI.

Your text payloads are transmitted over a secure HTTPS connection directly to the iFLYTEK translation service. The server acts as a clean proxy, retaining zero log history or cached copies.
