How to Use the WordPress MCP in Pydantic AI

Q: Can I manage my WordPress site using Pydantic AI?

Yes. The agent can create posts (createnewpost) and list categories (listblogcategories). All actions are governed by strict, predictable data types.

Q: What data types are exposed for privacy checks with WordPress and Pydantic AI?

The server exposes site user data (usernames/emails via listsiteusers), as well as post titles and slugs. The agent treats these specific data fields as strongly typed objects.

Ensure absolute data type correctness when managing WordPress content using the Pydantic AI framework.

Create Validated WordPress Posts with MCP Server

The `create_new_post` tool ensures that any new blog post you write conforms to a strict, predefined data schema. If the content is malformed, the agent fails immediately. It's great for making sure your generated articles always have required fields.

Audit and Read WordPress Content using MCP Server

Use `list_blog_posts` to get a list of existing posts, but then use `get_post_details` if you need the full data object. This guarantees that every field you read has a defined type. You can also check all site pages using `list_static_pages`.

Manage Site Users and Delete Content via MCP Server

If you need to clean up old entries, the `delete_post` tool handles removal. Before that, run `list_site_users` to get a validated list of every account. This helps keep your site's asset registry clean.

Setup guide

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

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

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

Common questions about WordPress MCP in Pydantic AI

The framework validates every single response the MCP Server sends back. If `list_blog_posts` returns an unexpected field, your agent fails loud and clear—no silent data corruption.

It forces type-safe interactions. You care more about correctness than speed, and this framework guarantees that every piece of content metadata you handle has a valid schema.

Yes. The agent can create posts (`create_new_post`) and list categories (`list_blog_categories`). All actions are governed by strict, predictable data types.

The server exposes site user data (usernames/emails via `list_site_users`), as well as post titles and slugs. The agent treats these specific data fields as strongly typed objects.

It's extremely reliable because of runtime validation. If the underlying MCP Server returns bad data, your agent won't proceed with it; it will throw a specific error.
