Perplexity

Validate Bird contacts at runtime

`create_contact` and `update_contact` require structured JSON strings for identifiers and metadata. Pydantic AI enforces these schemas at runtime, making sure your agent never passes malformed phone numbers or invalid display names to the Bird API. If your agent attempts to write bad data, the framework catches the validation error instantly. This prevents corrupt records from entering your database and stops broken API calls before they leave your environment.

Type-safe message dispatching with Pydantic AI

`send_message` requires a valid channel ID and recipient details to route SMS or WhatsApp messages. Pydantic AI validates these parameters against strict type definitions before the MCP Server processes the request. This runtime validation ensures your agent cannot send messages with missing channel IDs. You get clean, predictable outbound communication with zero silent failures or unhandled API exceptions.

Parse conversation histories without silent errors

`list_messages`, `get_conversation`, and `list_conversations` return complex nested communication data. Pydantic AI parses these payloads into strongly-typed Python models, ensuring your agent reads clean, verified data. If the Bird API structure changes, the framework raises a clear validation error instead of passing corrupted fields to your agent. This guarantees that your agent's decision-making is always based on accurate, well-formed data.

Setup guide

Set up Bird (MessageBird) 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": {
        "bird-messagebird-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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

Common questions about Bird (MessageBird) MCP in Pydantic AI

Install the package using `pip install "pydantic-ai-slim[mcp]"` and initialize `MCPToolset` with the Vinkius HTTP URL. Pass this toolset into the `toolsets` parameter of your Pydantic AI Agent. The agent will auto-discover all 10 tools.

Yes, you can define a Pydantic schema that validates the phone number format before passing it to `create_contact`. The framework will reject any invalid numbers before the tool is even executed. This saves API costs and keeps your contact list clean.

Yes, Pydantic AI supports both Streamable HTTP and SSE transports. You can connect to this hosted server using the unified `MCPToolset` class pointing to the Vinkius endpoint. Vinkius handles the underlying transport details for you.

Pydantic AI will catch the mismatch and raise a validation error rather than letting your agent process corrupted data. This strict type-safety prevents your agent from hallucinating or behaving unpredictably when API payloads change.

Your message logs, contact details, and API keys are processed inside an ephemeral V8 sandbox on Vinkius. Pydantic AI communicates with this sandbox via secure HTTPS. No communication data is persisted on the Vinkius platform, keeping your customer interactions private.
