How to Use the GetResponse MCP in Pydantic AI

Q: How do I connect the GetResponse MCP Server to Pydantic AI?

Install pydantic-ai-slimmcp. Create an MCPToolset pointing to your server URL, and pass it into the toolsets array of your Agent.

Q: Does Pydantic AI validate GetResponse custom fields?

Yes. The agent uses listcontactfields to fetch the available definitions. The framework then ensures any data written to those fields matches the expected types.

Q: How does the agent find a specific subscriber in GetResponse?

It triggers the findcontactbyemail tool. The framework parses the JSON response into your defined Python models for immediate use.

Type-safe GetResponse MCP Server tools

This GetResponse MCP Server enforces strict runtime validation on every single API response. Marketing APIs change, and silent failures corrupt your subscriber database. If the data does not match your exact Pydantic models, the agent crashes loudly instead of hallucinating. When your agent calls `get_contact_details`, the framework validates the returned fields against your schema. If a custom field is missing or incorrectly typed, you know immediately. You can also run `get_api_status` to ensure the upstream connection is stable before executing complex flows.

Strict subscriber management

Managing GetResponse subscribers requires absolute certainty. Adding users to the wrong email list breaks compliance and ruins your engagement metrics. Type validation guarantees your inputs are perfectly formatted before they ever hit the network. The agent prepares an `add_new_subscriber` request using strictly typed arguments for the email and list ID. If it needs to clean up old data, it uses `remove_subscriber` with the exact contact ID format required. There is no guessing.

Validate marketing infrastructure

Your agent can audit your entire GetResponse infrastructure and map it to Python objects. Complex marketing setups rely on interconnected webhooks and autoresponders. You get a fully typed representation of your marketing backend. The agent executes `list_active_webhooks` to pull your event configurations, then grabs your autoresponders via `list_active_sequences`. It parses everything through Pydantic, ensuring your automation triggers align perfectly with your internal application logic.

Setup guide

Set up GetResponse 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": {
        "getresponse-alternative-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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