Validate application schemas with Pydantic AI

The `create_new_application` tool registers a new application while enforcing strict structure on every field. If your agent tries to submit a draft with missing or malformed fields, the system fails loudly before hitting the network. This MCP Server integration prevents silent failures. By using `MCPToolset`, your Python code ensures that any payload sent to the API matches the expected schema exactly.

Query grant opportunities with strict type-safety

The `list_grant_funds` and `list_grant_categories` tools fetch active funding options directly into your type-safe agent. Your system parses these records into structured models, guaranteeing your application logic never breaks on unexpected null values. This type validation is model-agnostic, meaning you can swap your underlying LLM without rewriting your data extraction code. Your agent always receives predictable, clean data from the funding database.

Audit application reviews and user access safely

The `list_application_reviews` and `list_account_users` tools retrieve evaluator scores and user permissions. Your agent reads these records to build internal compliance dashboards that are guaranteed to match your local Python types. Because `MCPToolset` handles the connection to Vinkius externally, your code remains clean. You get instant access to these audit logs without writing custom API wrapper classes.

Setup guide

Set up Good Grants 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": {
        "good-grants-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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