Environment Agency Flood Monitoring MCP Server

A Model Context Protocol (MCP) server that provides access to the UK Environment Agency's Real Time Flood Monitoring API. This server allows you to access near real-time flood warnings, water level measurements, flow data, and monitoring station information.

🌊 Features

• 🚨 Flood Warnings & Alerts: Get current flood warnings and alerts with severity levels
• 📍 Flood Areas: Access information about flood alert and warning areas
• 🏭 Monitoring Stations: Find water level and flow monitoring stations across the UK
• 📊 Real-time Measurements: Access water levels, flows, and other measurements updated every 15 minutes
• 📈 Historical Data: Retrieve historical readings and measurements
• 🗺️ Geographic Filtering: Filter data by location using latitude, longitude, and distance
• 🔓 No API Key Required: Uses open government data with no registration needed

📄 Data Attribution

This server uses Environment Agency flood and river level data from the real-time data API (Beta), provided under the Open Government Licence.

🔄 API Updates and Reliability

• Data is updated every 15 minutes
• The API may redirect during high load - the client follows redirects automatically
• Responses may be cached for short periods
• No service level guarantee - not suitable for safety-critical applications

📋 Rate Limits and Best Practices

• For tracking all measurements, use a single call every 15 minutes
• Use geographic and parameter filters to reduce response sizes
• The API has built-in limits: default 500 items, maximum 10,000 for readings
• Use pagination with limit and offset parameters for large datasets
