How to Use the UK Environment Agency MCP in Pydantic AI

Q: How does Pydantic AI ensure data integrity when pulling flood warnings from the UK Environment Agency?

It validates every field returned by listfloods and getflood. If the structure changes or a critical field is missing, your agent throws an explicit validation error. You never get bad data.

Q: What specific tools does Pydantic AI use for monitoring stations from the UK Environment Agency?

You start with liststations to map all available sites. Then you call getstation, knowing that every piece of resulting data will pass through strict schema validation.

Q: Can Pydantic AI reliably pull real-time sensor readings from the UK Environment Agency?

Yes. The liststationreadings tool fetches the live numbers, and Pydantic guarantees that these values fit the expected data types. This prevents runtime errors in your production code.

Q: How is hydrology station data handled when using Pydantic AI with the UK Environment Agency?

The agent can use listhydrologystations for a global list view, and then gethydrologystation to pull parameters. Every resulting object adheres strictly to your defined schema.

Validating Flood Warnings via MCP Server

The tool `list_floods` lets you get a list of all active warnings from the UK Environment Agency. Since Pydantic validates every field, you'll know exactly which fields are present and correct. When you call `get_flood`, if the API sends unexpected data for a specific warning ID, your agent fails loudly. No silent corruption.

Handling Monitoring Station Details with Pydantic AI

Need to know about all monitoring sites? Use `list_stations` first. This gives you the list of identifiers for every active station. When you run `get_station`, the resulting data is validated against a model. If any field is missing or formatted wrong, your agent stops and tells you exactly what's broken.

Getting Specific Sensor Readings with Pydantic AI

To check current water levels, use `list_station_readings`. This pulls the actual sensor readings for a station ID. Every value here is checked by Pydantic before your agent uses it. If you're scoping out available metrics, run `list_measures` to see all tracked measures across the EA.

Setup guide

Set up UK Environment Agency 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": {
        "uk-environment-agency-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent UK Environment Agency transactions")
print(result.output)
