How to Use the Autobound MCP in Pydantic AI

Q: Does Pydantic AI validate the email outputs from Autobound?

Yes. Every cold email generated via generateemail is checked against your defined Pydantic models, stopping malformed copy from ever reaching a prospect.

Q: How do I check if the sales server is online?

Call checkautoboundstatus at the start of your script. This verifies the MCP connection before your agent attempts to run complex data enrichment tasks.

Type-safe lead enrichment with Pydantic AI

`enrich_contact` pulls prospect profiles and validates every returned field against strict Pydantic schemas at runtime. Avoid silent data corruption in your CRM. Unexpected data types cause the framework to raise a validation error immediately. This keeps your pipeline clean and prevents bad data from breaking downstream tools.

Validate outbound copy before sending

`generate_email` drafts messages, ensuring the output matches your exact structural requirements before it leaves the server. Sending broken templates is highly embarrassing, but validation prevents it. Executing `generate_linkedin` writes social messages with the same safety guarantees. Because every response is validated, you can trust that variables like prospect names are always formatted correctly.

Track and execute campaigns with zero runtime errors

`list_campaigns` and `get_campaign` find the right outbound track without risking runtime crashes. Managing active sequences requires absolute precision. Enrolling the prospect occurs once `execute_campaign` runs. The type-safe schema guarantees that you never pass missing fields to your sales platform.

Setup guide

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

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

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