Type-safe LinkedIn publishing with Pydantic AI

The `create_post` tool enforces strict type safety when your Pydantic AI agent publishes updates. LLMs love to hallucinate JSON structures, but Pydantic AI stops them. This MCP Server solves that by forcing every LinkedIn response through strict validation. When your agent calls the tool, the output is verified against precise schemas, catching formatting errors before they hit the live API. If the LLM tries to pass bad arguments to the LinkedIn tool, the Pydantic AI framework raises a validation error immediately. You get clean, predictable execution without worrying about silent post failures or broken links on your feed.

Validate organization metadata before processing

You can fetch and validate your company pages using the `list_organizations` tool in Pydantic AI. Pulling LinkedIn company data shouldn't be a guessing game in your pipeline. Use the tool to get your managed pages, then inspect them with `get_organization` knowing every field is strictly typed. This structure prevents your Pydantic AI pipeline from crashing when LinkedIn returns unexpected null values or modified schemas. The validation layer catches discrepancies instantly, keeping your internal data models clean.

Secure profile verification and email checks

The `get_me` tool retrieves and validates the active user's profile details within your Pydantic AI setup. Before running automated LinkedIn campaigns, verify the user's identity. The agent calls this tool and `get_email` to grab the primary email address, validating both against your strict Pydantic schemas. This ensures your Pydantic AI agent is always acting on behalf of the correct, verified professional. You can easily pipe this validated LinkedIn data into your downstream databases without manual type casting.

Setup guide

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

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

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