Validate BlackTwist posts with Pydantic AI

The `create_post` tool lets your agent publish updates with guaranteed payload validation. Connecting this MCP server to Pydantic AI intercepts the outgoing data, checking that the BlackTwist provider ID and text content exactly match your defined schemas before hitting the wire. If the agent generates an invalid payload, the Pydantic AI framework triggers a validation error immediately. This prevents malformed drafts from ever reaching your BlackTwist accounts.

Audit BlackTwist queues with Pydantic AI

The `list_posts` and `get_post` tools retrieve active drafts and scheduled content for structural validation. Pydantic AI parses the BlackTwist API response against your strict Pydantic models, weeding out empty fields or corrupted timestamps. This strict validation ensures your agent never acts on corrupted scheduling data. The Pydantic AI framework fails loudly if the BlackTwist MCP Server returns unexpected formats, protecting your downstream automation.

Parse BlackTwist metrics in Pydantic AI

The `get_analytics_metrics` and `get_daily_recap` tools return structured engagement data directly to your type-safe agents. Pydantic AI enforces types on every BlackTwist metric, ensuring that likes, shares, and impressions are cast to strict integers. You can confidently feed these validated figures into financial or reporting pipelines. Because the Pydantic AI framework is model-agnostic, you can switch from OpenAI to a local model without rewriting your BlackTwist validation schemas.

Setup guide

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

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

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