How to Use the Groq MCP in Pydantic AI

Q: Can I use Groq models with Pydantic AI safety guardrails?

Yes, you can run moderatecontent to check user inputs before passing them to the chatcompletion tool. Pydantic AI validates the moderation response structure at runtime. This ensures your safety checks are always executed reliably.

Q: How does listmodels help with type-safe routing?

The listmodels tool returns the active hardware endpoints, which are validated against a Pydantic model. Your agent can inspect this list to ensure it only routes requests to supported Llama or Mixtral models. This prevents runtime errors caused by deprecated model IDs.

Run type-safe, ultra-fast Groq LPU inference with strict Pydantic AI runtime validation using this MCP Server.

Enforcing schemas with Pydantic AI and Groq

The `structured_output` tool forces the Groq LPU to return data matching your exact Pydantic AI schemas. If the model returns a missing field or incorrect type, the framework raises a validation error immediately. This prevents corrupt data from entering your production databases. You get the speed of LPU inference combined with the safety of runtime type checking.

Type-safe audio processing via this MCP Server

The `transcribe_audio` and `translate_audio` tools convert voice files to text, which the agent immediately validates. Pydantic AI ensures the resulting transcription conforms to your structured data models. If the audio translation fails to meet your quality criteria, the agent catches the error at runtime. This guarantees that only valid, well-formed text enters your downstream processing pipelines.

Validated vector generation for Pydantic AI

The `create_embedding` tool generates precise vector arrays that are instantly checked against Pydantic's float list models. This ensures your vector database never receives corrupted or malformed embeddings. If the LPU returns an unexpected array size, the framework halts the execution block. This protects your search index from indexing faulty dimensional data.

Setup guide

Set up Groq 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": {
        "groq-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to Groq tools.",
)

result = await agent.run("List recent Groq transactions")
print(result.output)

Common questions about Groq MCP in Pydantic AI

Install the slim package with MCP support, then create an MCPToolset pointing to the server HTTP endpoint. Pass this toolset object directly into your Agent's toolsets list. Note that the older MCPServerHTTP class is deprecated.

The framework raises a validation error immediately, causing the agent to fail loudly instead of passing corrupt data. This is particularly useful when using `structured_output` for complex data extraction. You can catch these errors in standard try-except blocks.

Yes, you can run `moderate_content` to check user inputs before passing them to the `chat_completion` tool. Pydantic AI validates the moderation response structure at runtime. This ensures your safety checks are always executed reliably.

The `list_models` tool returns the active hardware endpoints, which are validated against a Pydantic model. Your agent can inspect this list to ensure it only routes requests to supported Llama or Mixtral models. This prevents runtime errors caused by deprecated model IDs.

All text prompts and audio files are processed in memory within an ephemeral V8 sandbox. The server does not write any data to persistent storage. Your API credentials are encrypted and injected dynamically at runtime.
