How to Use the Code Integrity Prover MCP in Pydantic AI

Q: How does Code Integrity Prover enforce type safety in Pydantic AI?

It exposes the validatecodeintegrity tool to your agent. The tool performs static analysis on the generated code, rejecting any instances of any, unsafe, or ignored types before the agent can output the result.

Q: How do I register the Code Integrity Prover MCP Server in my Pydantic AI agent?

Instantiate MCPToolset with your Vinkius server URL and pass it to the agent's toolsets argument. The agent will automatically discover and use the validation tool during runtime.

Hardline code validation for Pydantic AI agents that demand strict type safety and zero workarounds using this MCP Server.

Perplexity

Fail loudly on lazy code in Pydantic AI

Pydantic AI is built for developers who hate silent failures. The `validate_code_integrity` tool fits this philosophy by rejecting any code that uses `any` types, empty catch blocks, or placeholder stubs. If your agent tries to cheat, the tool triggers a loud validation error. This prevents your agent from passing corrupt or incomplete code blocks downstream. You get strict, deterministic checks on every single line of generated code before it can bypass your runtime schemas.

Connect the MCP Server using unified toolsets

Forget deprecated HTTP server classes. Use the modern `MCPToolset` class to point your Pydantic AI agent directly to the Vinkius endpoint over streamable HTTP or SSE transports. Once registered, your agent gains immediate access to the integrity checker. It can run automated checks on Python, TypeScript, or any other target language to verify that no magic numbers or duplicated code segments exist.

Enforce code quality across any LLM backend

Your Pydantic AI agent code quality can vary wildly depending on the model you use. This MCP Server acts as an external, model-agnostic gatekeeper that keeps code generation consistent across all your LLM backends. It forces the model to rewrite code until it passes all five integrity checks. This removes the need to write complex system prompts begging the model to avoid TODOs and placeholder functions.

Setup guide

Set up Code Integrity Prover 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": {
        "code-integrity-prover-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent Code Integrity Prover transactions")
print(result.output)

It exposes the `validate_code_integrity` tool to your agent. The tool performs static analysis on the generated code, rejecting any instances of `any`, `unsafe`, or ignored types before the agent can output the result.

Instantiate `MCPToolset` with your Vinkius server URL and pass it to the agent's `toolsets` argument. The agent will automatically discover and use the validation tool during runtime.

The validation fails immediately. The tool returns a structured error pointing out the placeholder, forcing your Pydantic AI agent to write the actual implementation instead of leaving a stub.

Yes. You can connect to the Vinkius hosted server using either Streamable HTTP or SSE transports depending on your network requirements.

Yes. Your source code and abstract syntax trees are processed in real-time inside a secure, zero-trust V8 sandbox. The data is analyzed in memory and immediately discarded, meaning your code is never saved or used for training.
