How to Use the CData Connect Cloud MCP in Pydantic AI

Q: Can I test database connections programmatically using Pydantic AI?

Yes. Your agent runs cdatatestconnection to ping the target proxy. You can write a validation loop that ensures the connection is healthy before executing any agent steps.

Q: How do I handle schema drift in my database?

Your agent runs cdatagettablecolumns to inspect table layouts dynamically. If a column type changes, your Pydantic AI validation catches the mismatch immediately, allowing you to handle the error gracefully.

Run type-safe SQL queries and inspect database schemas directly from your Pydantic AI agents.

Type-safe schema inspection in Pydantic AI

`cdata_execute_query` is the tool your agent uses to run raw SQL statements against your connected databases. Because you are using this MCP Server with Pydantic AI, the returned data structures are validated against your Python schemas at runtime to prevent silent data corruption. If the database returns unexpected null values or altered column types, your agent catches the validation error instantly. This guarantees that only clean, structured data enters your downstream application logic.

Runtime Schema Auditing

`cdata_get_table_columns` is the tool your agent uses to fetch precise schema fields and definitions for a target database table. Before running any queries, your agent verifies column definitions against your Pydantic models to ensure complete structural alignment. This discovery phase is backed by `cdata_get_schema_metadata`, which exposes the interaction limits of your backend graph. Your agent adapts its queries dynamically based on the exact limits returned by the server.

Discover active workspaces and connections

`cdata_list_workspaces` is the tool that lists all active organizational data groups configured in your account. Your agent uses this to find the correct logical segment before querying individual connections. To map out available data sources, the agent runs `cdata_list_connections` and verifies their health with `cdata_test_connection`. This proactive checking prevents runtime execution failures when databases go offline.

Setup guide

Set up CData Connect Cloud 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": {
        "cdata-connect-cloud-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent CData Connect Cloud transactions")
print(result.output)

Common questions about CData Connect Cloud MCP in Pydantic AI

You instantiate the MCP Server toolset with your Vinkius URL and pass it to your Pydantic AI agent. The agent instantly gains access to tools like `cdata_execute_query` for database interactions.

Yes. You can define a Pydantic model for your expected query results. The agent executes `cdata_execute_query` and parses the output directly into your typed model, raising errors on schema mismatches.

Yes. Your agent runs `cdata_test_connection` to ping the target proxy. You can write a validation loop that ensures the connection is healthy before executing any agent steps.

Your agent runs `cdata_get_table_columns` to inspect table layouts dynamically. If a column type changes, your Pydantic AI validation catches the mismatch immediately, allowing you to handle the error gracefully.

The MCP Server manages connection strings entirely on the backend, away from the client. Your Pydantic AI code only interacts with the safe proxy tools, ensuring sensitive database credentials never leak into your application logs or model prompts.
