Validate Celigo integrator.io data with Pydantic AI

Silent data corruption can break downstream databases before you even notice. This MCP Server ensures that every response from `get_flow_details` is validated against strict Pydantic models before your Pydantic AI agent acts on it. If Celigo's API returns unexpected fields or missing data, Pydantic AI halts execution immediately. This keeps your automated Celigo pipelines safe from malformed payloads.

Type-safe error tracking with this MCP Server

Monitoring Celigo flows shouldn't rely on guesswork. Your Pydantic AI agent calls `list_integration_errors` to get structured, type-checked lists of active failures. The Pydantic AI framework parses the Celigo error payloads directly into typed Python objects, making it easy to route issues to the correct slack channel or on-call engineer.

Reliable flow control in Pydantic AI pipelines

Before executing a write operation, your Pydantic AI agent needs absolute certainty about the target state. It uses `list_integration_flows` to verify which Celigo pipelines are active. Once verified, the Pydantic AI agent safely calls `run_integration_flow` knowing the input parameters strictly match your defined schema.

Setup guide

Set up Celigo integrator.io 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": {
        "celigo-integratorio-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent Celigo integrator.io transactions")
print(result.output)

Common questions about Celigo integrator.io MCP in Pydantic AI

Use the unified `MCPToolset` with your Vinkius HTTP URL. Pass this toolset directly into your `Agent` constructor's `toolsets` argument to expose tools like `list_integrations` to your model.

The Pydantic AI framework intercepts the response. If the error schema doesn't match the expected type, it raises a validation error, preventing your agent from processing bad API data.

Yes, Pydantic AI is model-agnostic. You can use this server to trigger `run_integration_flow` using OpenAI, Anthropic, or local models running on your own machine.

Yes, Pydantic AI supports both Streamable HTTP and SSE transports. You can configure the unified `MCPToolset` to connect to your Vinkius endpoint using either protocol.

The connection runs through Vinkius's zero-trust gateway, which handles all authentication tokens securely. Your flow schema and integration credentials are never stored, keeping your corporate automation setup private.
