Nothing serious here today
Today is the operative word: we check Postcodecontext every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

data
get_data_attribution
$0.00 USDC reference tool (no payment or authentication required; subject to Terms of Service): Retrieve official statutory attribution statements, Crown copyright notices, Royal Mail Gridlink sublicence details, and Open Government Licence v3.0 metadata across all 19 contributing data providers (ONS, OS, Royal Mail, HM Land Registry, Registers of Scotland, MHCLG, Ofcom, Scottish Government, Welsh Government, DfE, CQC, PHS, NWSSP, DfT, ORR).
get_data_dictionary
$0.00 USDC reference tool (no payment or authentication required; subject to Terms of Service): Retrieve exact field specifications, mathematical calculation formulas, statistical scales, and data sources for any metric across Great Britain in the Postcode Context database.
compare
compare_postcodes
Use when you need to directly contrast 2 to 5 Great Britain postcodes across affluence, safety, housing cost per m², broadband, and family suitability. Returns full profiles by default; use view="brief" (~80 tokens per postcode) to keep context compact alongside the comparison ranking. Do not use for single postcode inspection (use lookup_postcode) or bulk batches of >5 postcodes (use enrich_postcodes).
demographics
get_demographics_and_deprivation
Retrieve Census demographic breakdown (ONS Census 2021 / NRS Scotland Census 2022 income estimate, qualifications, tenure, employment, age) and statutory IMD deprivation deciles (IoD 2025, WIMD 2025, SIMD 2020 crime safety, education, living environment) for any Great Britain postcode. Covers England, Scotland, and Wales.
enrich
enrich_postcodes
Bulk demographic, economic, and spatial lookup for 1 to 50 Great Britain postcodes. Returns brief profile by default (~80 tokens per postcode) to prevent context blow-up; use view="full" when all 113 metrics are needed. Cost-effective for 6 to 50 postcodes ($0.050 flat fee). For 1 postcode use lookup_postcode ($0.005); for 2 to 5 postcodes use compare_postcodes ($0.010). Do not use when detailed side-by-side comparative rankings are required (use compare_postcodes).
lookup
lookup_postcode
Use when you need demographic, property, EPC energy efficiency, broadband, or socio-economic context for a Great Britain unit postcode (England, Scotland, Wales). Returns full profile by default; use view="brief" (~80 tokens) for low-token, concise briefings when managing context budget. Do not use for non-GB postcodes (e.g. Northern Ireland BT) or when comparing multiple postcodes simultaneously (use compare_postcodes instead).
postcode
get_postcode_ai_brief
Retrieve an ultra-lightweight, token-efficient natural language briefing, affluence tier, and persona profile (~80 tokens) for fast autonomous agent decision-making across Great Britain. Covers England, Scotland, and Wales (excludes Northern Ireland BT postcodes).
property
get_property_and_energy_profile
Retrieve real estate valuation (HM Land Registry / Registers of Scotland median house price, price per sqm, 3yr sales volume), EPC energy efficiency (current/potential band, retrofit upside), and Ofcom gigabit broadband connectivity for any Great Britain postcode. Covers England, Scotland, and Wales (excludes Northern Ireland BT postcodes).
screen
screen_postcodes
Rank and screen 2 to 10 Great Britain postcodes by a specific target metric (affluence, house price, crime safety, broadband speed, family suitability, or connectivity). Returns a sorted leaderboard. For 11 to 50 postcodes use enrich_postcodes; for full cross-metric comparison of 2 to 5 postcodes use compare_postcodes.
summarise
summarise_outcode
Use when you only have an outward code / district (e.g. SW1A, BB7, EH1, CF10) and need high-level district demographic and property statistics (~150 tokens). Do not use when an exact full unit postcode is available (use lookup_postcode).

Postcodecontext — questions
Answers built from our own checks of this server.
What can Postcodecontext do?
It exposes 10 tools, read directly from the server on our last check. Among them: compare_postcodes, enrich_postcodes, get_data_attribution, get_data_dictionary, get_demographics_and_deprivation, get_postcode_ai_brief and 4 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is Postcodecontext working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 24 of 24 checks got a reply (100.0%), average response time 361 ms. The bar chart above shows every period we have measured.
How do I connect Postcodecontext?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Postcodecontext need an API key?
No. Postcodecontext completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Postcodecontext?
It answers our handshake in 361 ms on average, which is faster than 37% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Postcodecontext open source?
We cannot say either way: written in JavaScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
