Validate scripture data schemas in Pydantic AI

The `get_bible_verse` tool returns specific verses, while `get_bible_details` delivers translation metadata. Pydantic AI validates every field against your schema at runtime, catching formatting errors before they hit your application. If the API returns unexpected null values or altered structures, your system raises a validation error immediately. This prevents corrupted text from silently leaking into your production UI.

Map translation structures safely

The `list_bible_books` tool outputs the books of a version, and `list_bibles` lists all available translations. This lets your agent build dynamic dropdowns or menus that you know are backed by valid data. You don't have to write manual parsing code. The framework handles the JSON conversion and ensures the output matches your exact Python models.

Search texts using this validated MCP Server

The `search_bible_text` tool searches translations for keywords, and `get_bible_chapter` retrieves entire chapters. Your agent can search and compile passages with the confidence that every string is typed. This MCP Server keeps your code clean, readable, and easy to test.

Setup guide

Set up Bible API 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": {
        "bible-api-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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