Perplexity

Type-Safe Federal Contract Parsing

Government data structures change constantly, but your Pydantic AI agent catches anomalies before they corrupt your database. When the agent calls `get_contract`, the framework validates the response against your exact Pydantic models. If the HigherGov API returns a string where you expected a float for the award value, the agent fails loudly. You get a clear validation error instead of a silent failure, keeping your downstream pipeline perfectly clean.

Model-Agnostic Government Research

You might use Claude for reading solicitations and a local model for drafting compliance matrices. This MCP Server integration works flawlessly across both. You pass MCPToolset to your agent, and it maps tools like `list_opportunities` into the specific format required by your chosen LLM. The framework handles the translation. Your agent executes `get_documents` to grab the RFP files, regardless of whether you are running a massive frontier model or a small local instance.

Strict Awardee Intelligence via MCP Server

Tracking competitor wins requires exact data. Your agent runs `list_awardees` to find a specific vendor, then loops through `get_awardee` to build a profile of their recent federal work. Because you built this with Pydantic AI, every single field from the UEI number to the NAICS code gets type-checked at runtime. Your business development team receives an intelligence brief built entirely on verified, structured data.

Setup guide

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

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

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

Common questions about HigherGov MCP in Pydantic AI

You instantiate MCPToolset with your Vinkius HTTP endpoint. Assign that toolset to your agent constructor, and the framework automatically discovers the twelve available endpoints.

The framework throws a ValidationError immediately. Your agent will not process a list_grants response if it violates the schema you defined in your Python code.

Any model supported by the framework can execute these tools. You can run a local Llama instance and still fetch federal spending data via get_agency.

Standard requests leave you vulnerable to silent schema changes. This MCP setup guarantees that every byte pulled from get_opportunity matches your strict type definitions before execution continues.

Your agent retrieves public contract award values and agency budgets. Vinkius strips all authentication headers at the sandbox boundary, ensuring your local model state stays completely separate from the external API call.
