Perplexity

Validate employee profiles at runtime

The `get_user_details` tool fetches contact information, department mappings, and employment status. Pydantic AI validates this payload against strict schemas immediately, stopping dirty or incomplete data from corrupting your database. We use `list_users` to scan your entire employee directory with the same level of type safety. If an API response contains an unexpected null value or an invalid email format, your agent fails loudly before executing bad logic.

Type-safe catalog parsing with this MCP Server

The `list_catalog` tool resolves learning object IDs, titles, and training types. Your agent uses these validated objects to build structured training recommendations that perfectly match your internal schemas. Pair this with `get_course_details` to enforce strict rules around course availability and durations. If a training module lacks a required duration field, the validation layer catches it before your agent presents it to a user.

Track performance reviews safely

The `list_performance_reviews` tool pulls active evaluation cycles, manager-employee pairs, and review statuses. This keeps your HR pipelines accurate by ensuring every retrieved review matches your defined Python models. Use `list_departments` to map these reviews to specific organizational units. The agent builds clean, nested department trees that you can safely pass to downstream analytics tools.

Setup guide

Set up Cornerstone OnDemand 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": {
        "cornerstone-ondemand-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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