How to Use the Channels MCP in Pydantic AI

Q: How do I load Channels tools into my Pydantic AI agent?

Import MCPToolset from pydantic-ai-slimmcp and initialize it with your Vinkius HTTP endpoint. Pass the toolset directly into the toolsets argument of your Agent constructor to auto-discover all 12 tools, including listcontacts.

Q: Does Pydantic AI support SSE transport for Channels?

Yes, MCPToolset natively supports both SSE and Streamable HTTP transports. You can connect to your hosted server on Vinkius using whichever protocol fits your application architecture best.

Q: Can I retrieve call recording links safely using this MCP Server?

Yes. The agent uses getcallrecording to fetch the recording URL. Pydantic AI validates that the returned payload contains a correctly formatted URL string before your application attempts to download it.

Perplexity

Enforce strict schemas on customer contact updates

Never worry about your agent passing bad phone numbers or corrupted emails. When your agent calls `create_contact` or `update_contact`, Pydantic AI validates the inputs against strict schemas before sending them to the API. If the agent tries to pass an invalid string format to `delete_contact` or `get_contact`, the framework raises a validation error immediately. This stops corrupted data from breaking your production database.

Validate call metrics at runtime with this MCP Server

When pulling call analytics with `get_call_stats` or `list_calls`, you need to know the data matches your internal models. This MCP Server outputs clean JSON that Pydantic AI parses directly into typed Python objects. If a call record is missing a required timestamp, the validation layer catches it instantly. You get deterministic behavior when processing call recordings via `get_call_recording`, making your reporting pipelines highly reliable.

Type-safe webhook management using Pydantic AI

Webhook payloads are notoriously fragile. By using `create_webhook` and `list_webhooks` within Pydantic AI, you ensure that every registered URL and event subscription complies with your system's strict type definitions. This setup lets you query active webhooks or account details via `get_account_info` and `list_users` without worrying about unexpected null fields. The framework guarantees that what your agent receives matches your code's expectations.

Setup guide

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

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

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