How to Use the TrackingTime MCP in Pydantic AI

Q: What happens if I use the Pydantic AI with invalid time entries?

The system won't process it. If addtimeentry receives a payload that doesn't match the required structure (e.g., wrong data type for hours), the agent catches the validation failure instantly.

Q: Can I list projects and clients reliably with Pydantic AI? How does TrackingTime help?

Absolutely. listprojects and listcustomers guarantee structured output. You get reliable project names and client IDs, making cross-referencing for reports foolproof.

Q: Is the data from listtasks always correct when using TrackingTime with Pydantic AI?

Yes. listtasks outputs are validated against your schema. You get reliable task names and associated metadata, so you don't have to worry about mismatched keys in your automation pipeline.

Ensure perfect time tracking data with Pydantic AI's MCP Server validation.

Reliable Time Entry Management

The `list_time_entries` tool pulls all recorded timesheets, and `add_time_entry` lets your agent submit new entries. Because of Pydantic validation, you'll never get a corrupted or unexpected time log field. If the API returns malformed data—say, a date string instead of an integer—the agent fails loudly, telling you exactly where the structure broke.

Type-Safe Project and Client Structure

Agents use `list_projects` to get project lists. They can also call `list_customers` for a reliable client roster. Every time these functions run, the data returned is guaranteed to match your defined Pydantic model. This guarantees that when you build complex reporting logic, the input structure is always correct.

Controlled Task and User Modification

When a task needs adjusting, the `update_task` tool handles it. For new work, `create_task` builds the record. You can also manage team visibility using `list_workspace_users` or checking your own status with `get_user_profile`. Correctness is key here; if a required field for an update is missing, the agent doesn't proceed silently—it flags the error immediately.

Setup guide

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

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

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