How to Use the AbstractAPI MCP in Pydantic AI

Q: How do I add AbstractAPI to my Pydantic AI project?

Install pydantic-ai-slimmcp and initialize an MCPToolset with your Vinkius HTTP endpoint. Pass this toolset array to your Agent constructor. Do not use the deprecated MCPServerHTTP class.

Q: Does Pydantic AI support live currency conversions via AbstractAPI?

Yes. The exchangerate tool fetches real-time base-to-target currency data. The framework ensures the returned rate is a valid float before your application processes the transaction.

Q: Can the AbstractAPI MCP Server capture web pages?

Your agent calls the websitescreenshot tool to render a full-page headless browser view. It returns a permanent URL that you can store or pass to a multimodal model for further analysis.

Enforce strict type validation on AbstractAPI responses using Pydantic AI to guarantee accurate data enrichment.

Validate contact fields with Pydantic AI

Deliverability scores come from the `validate_email` tool after checking MX records. Runtime validation checks this numeric score against your schema, failing loudly on bad types instead of silently corrupting your database. Telecom data routes through the `validate_phone` tool to identify carriers. The framework blocks execution if the agent expects a mobile designation but gets an unknown format.

Type-safe company enrichment MCP Server

Extracting industry and employee counts happens via the `enrich_company` tool. Model-agnostic frameworks let you use local LLMs to trigger this lookup while guaranteeing the output structure matches your strict models. The `validate_vat` tool confirms EU tax numbers for financial pipelines. Registered legal addresses return to your billing system for verification before generating invoices.

Parse location and holiday data

Network addresses map to specific ISPs and timezones using the `geolocate_ip` tool. Tagging user sessions with this endpoint guarantees the location fields perfectly match your expected types. Official public dates output from the `list_holidays` tool based on an ISO country code. Exact UTC offsets arrive via the `get_timezone` tool so your agent can properly validate date formats.

Setup guide

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

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

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

Your agent calls the website_screenshot tool to render a full-page headless browser view. It returns a permanent URL that you can store or pass to a multimodal model for further analysis.

Pydantic AI throws a validation error immediately. If the generate_avatar tool fails to return a valid URL string, the agent catches the failure rather than passing a broken link to your frontend.

Every request passes through a V8 Isolate Sandbox on Vinkius. When your agent queries an email address or domain name, the ephemeral environment handles the network call and instantly terminates. We do not store the payloads your MCP Server validates.
