Propbar MCP Server

MCP server providing UK property research tools for AI assistants. Enables Claude, GPT, and other LLMs to search properties, analyse area safety, find nearby schools, explore demographics, and build automated valuation models (AVMs).

Powered by Propbar's comprehensive UK property database covering 30+ million properties.

Use Cases

Build Your Own AVM

The get_comparables tool provides access to a comprehensive property search with 50+ filterable fields - perfect for building automated valuation models:

- Transaction Data: Sale history with dates and amounts, current asking prices
- Market Status: For sale, SSTC, under offer, reserved, back on market dates
- Property Attributes: Type, beds, baths, floor area, construction age
- EPC Data: Energy ratings (A-G), efficiency scores, potential ratings
- Tenure & Charges: Freehold/leasehold, lease years remaining, service charges, ground rent
- Pricing Metrics: Price per sqm, price per sqft, price changes over time
- Listing Intelligence: Days on market, price reductions, portal links

Example AVM workflow:

1. get_comparables({ latitude, longitude, propertyType: "flat", bedrooms: 2 })

2. Filter by sale date (last 12 months) and distance

3. Adjust for differences (floor area, EPC rating, condition)

4. Calculate £/sqft and apply to subject property

Property Research for Buyers

Help users make informed decisions with comprehensive area data:

- Crime & Safety - Is this area safe? How does it compare?
- Schools - What schools are nearby? Ofsted ratings?
- Demographics - Who lives here? Age, tenure, household types?
- Market Analysis - What are similar properties selling for?
