Type-safe Beamer post creation via MCP Server

The `create_post` tool allows your Pydantic AI agent to publish new announcements to your Beamer feed. Because Pydantic AI validates all inputs at runtime, you can guarantee that fields like titles and body content never contain malformed data. That's how you avoid public-facing typos. If your model tries to send an invalid payload to `update_post`, the framework catches the validation error immediately before making the API call. This prevents broken formatting or empty announcements from ever reaching your users.

Validated feedback parsing with Pydantic AI

The `list_feedback` tool retrieves user reviews and feature requests from Beamer, which are then parsed directly into strongly-typed Pydantic models. Your agent can safely inspect user sentiment without worrying about unexpected null fields or missing keys. It makes handling raw user input highly predictable. For deeper analysis, the agent uses `get_feedback_details` to inspect specific comments. If the API response doesn't match your defined schema, the agent raises a clear validation error rather than silently failing.

Strict analytics reporting and user audits

The `get_analytics` tool fetches engagement metrics from your Beamer dashboard to track how users react to your updates. Pydantic AI validates these metrics against your internal schema to ensure your reporting pipelines get clean numbers. When auditing your audience with `list_users`, the framework verifies that every user record contains valid email addresses and registration dates. This strict validation keeps your downstream databases clean and free of corrupted records.

Setup guide

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

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

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