Type-safe project operations with Pydantic AI

Every tool response from Nifty is validated against your Pydantic models. If the API returns garbage, your agent throws an error before it can act on it. This keeps your project data clean. Use `update_task_metadata` with confidence, knowing the schema matches your local requirements exactly.

Reliable task management via MCP Server

Stop worrying about silent API failures. Your agent uses `mark_task_as_complete` and verifies the result against a schema before moving to the next step. It prevents state corruption in your project board. You get a stable, predictable interface for all your task-related automation.

Granular data retrieval for Pydantic AI

Fetch exactly the data your agent needs to make decisions. It uses `get_project_details` to pull board configuration and `get_task_info` for specific task details. Everything is strictly typed. This ensures your code doesn't break when the Nifty API evolves or returns unexpected fields.

Setup guide

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

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

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