Type-Safe User Provisioning

This MCP server exposes user creation tools like `create_new_user` directly to your Pydantic AI agent. Every user profile returned is validated against strict Pydantic models at runtime to ensure no null fields or corrupted schemas slip through. If the Crowd API returns an unexpected payload format, the system fails loudly and immediately. This strict validation prevents your agent from acting on corrupt data or writing malformed schemas to your database.

Validate memberships with this MCP Server

This tools suite exposes group mapping tools like `list_user_memberships` and `get_group_details`. Your agent verifies user access rights, ensuring that every group object returned matches your defined Python types. By avoiding silent failures, you ensure that security audits are 100% accurate. The model-agnostic framework lets you run these strict checks using any LLM provider while keeping validation logic local.

Search and validate directory profiles

The server queries directories using `search_users_by_attribute` and `get_user_details`. Our agent parses the resulting user profiles, stripping out unvalidated fields before they reach your application logic. You configure this by passing the MCPToolset directly to your agent's toolsets parameter. It guarantees that every search result matches your strict type definitions before the agent can proceed.

Setup guide

Set up Atlassian Crowd 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": {
        "atlassian-crowd-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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

Common questions about Atlassian Crowd MCP in Pydantic AI

The framework intercepts the incoming JSON payload from the tool execution. It validates the fields against a strict internal schema, throwing a validation error if any directory attribute is missing or malformed.

Yes, the framework is completely model-agnostic. You can swap between OpenAI, Anthropic, Gemini, or local models without modifying your Crowd tool configurations.

You wrap your agent execution block in a standard Python try-except block catching ValidationError. This lets you handle API discrepancies or schema changes gracefully in your application code.

No, you should use the unified MCPToolset class pointing to your Vinkius HTTP endpoint. The older MCPServerHTTP class is deprecated and should be avoided in new deployments.

Your directory credentials and user profiles are handled strictly inside a secure, ephemeral runtime. The server executes commands directly against your Crowd API, ensuring that no sensitive user data persists after the tool call completes. Vinkius maintains a strict zero-trust posture with zero storage of your data.
