How to Use the Gripr MCP in Pydantic AI

Q: How do I integrate the Gripr MCP server into a Pydantic AI agent?

Install pydantic-ai-slimmcp and initialize MCPToolset with your Vinkius HTTP endpoint. Pass this toolset to your agent to immediately access all eleven construction management tools.

Q: How does this MCP server handle project details?

The server uses getprojectdetails to return structured metadata about your projects. Your agent can use this information to determine budget burn rates and timeline compliance.

Q: How does this server protect my task lists and workspace user data?

All interactions with listtasks and listworkspaceusers run through an isolated V8 sandbox on the Vinkius MCP network. Your credentials and project data are never written to disk, ensuring complete execution privacy.

Enforce type-safe hours registration with Pydantic AI

The `register_hours` tool writes hours to your project database, and this SDK validates the inputs at runtime. Your Pydantic AI agent cannot submit broken payloads or malformed timestamps, preventing database corruption. If the agent attempts to log invalid data, the framework fails loudly with a validation error. This strict enforcement over the MCP Server connection guarantees that all Gripr labor data matches your exact structural requirements.

Validate safety compliance forms without silent failures

The `list_forms` tool retrieves critical HSE and QA records from your construction sites using the secure MCP. Your Pydantic AI agent parses these forms using Pydantic models to guarantee that every required safety field is present and correctly formatted. Because the framework is model-agnostic, you can use any LLM to analyze Gripr safety risks while maintaining strict programmatic guardrails. This setup ensures that missing safety data is caught instantly.

Manage tasks and projects with absolute structural integrity

The `create_task` tool lets your agent assign action items to resolve safety hazards or operational delays. The Pydantic AI agent uses `list_tasks` to verify existing workloads, ensuring no duplicate tasks are generated. When establishing new accounts, the agent uses `create_customer` to set up client profiles. Every Gripr field is verified against your Pydantic schemas before the request hits the API.

Setup guide

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

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

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