    How to connect

    How to connect acuris-mcp to Claude

    The server address to paste into Claude settings:

    https://api.acuris-geo.com/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    How to connect acuris-mcp to ChatGPT

    The server address to paste into ChatGPT settings:

    https://api.acuris-geo.com/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).

    6. In a new chat open + → Apps/Connectors and enable the connector.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    Authorization

    On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

    validate_addressValidate and standardize one postal address (240+ countries; UK via the official Royal Mail PAF with UDPRN + UPRN). Give `country` as ISO-3 lowercase (e.g. usa, can, deu, gbr) plus EITHER a free-text `address_line` OR fielded parts (street, house_number, city, state, postcode). Returns an honest verdict — status "verified" (exact) or "corrected" (fixed), or partial_match with reasons — plus the standardized form, confidence, coordinates with an explicit accuracy_type, and, for street-accurate USA/Canada matches, a FREE `enrichment` block (census tract, block group, FIPS, CBSA/MSA, congressional district, school district / Canadian equivalents). Cost: 1 validation credit per successful lookup; no-match and errors are refunded automatically (you pay for results, not attempts).
    validate_addresses_batchValidate up to 50 addresses in one call (mixed countries allowed). `addresses` is a list where each entry is either a free-text string, or an object {"input": <string or fielded object>, "country": "iso3"}. Entries without their own country use the `country` parameter. UK (gbr) rows are routed individually to the Royal Mail PAF service; everything else goes through the batch endpoint. Results come back in the same order, each with the same shape as validate_address. Cost: 1 validation credit per successfully validated row; failed rows are refunded. For files bigger than 50 rows, call this tool repeatedly.
    enrich_us_ca_addressAddress → census & geographic codes (USA + Canada), FREE with validation. USA: state & county FIPS, census tract (11-digit GEOID), block group, CBSA/MSA, congressional district (119th Congress), school district. Canada: province, census division, dissemination area, census subdivision, census tract, CMA/CA, federal electoral district. Sources: US Census Bureau TIGER/Line; Statistics Canada (open data). The enrichment is attached when the address resolves to a house-number- or street-accurate match; centroid-only matches return no enrichment (the point could fall in the wrong area). `country` must be "usa" or "can". Cost: 1 validation credit (the enrichment itself is free); failed lookups are refunded.
    geocode_addressForward-geocode an address to coordinates (lat/lng) with an explicit accuracy_type — you always know what you got. accuracy_type is an OPEN set; new tiers are added as reference data improves. Do NOT write code that treats an unrecognised value as a failure. Branch on the boolean `point_coordinate` instead, which is true when the coordinate identifies one address. Current values: rooftop and arrival_point (both point coordinates — a point on the building, or the property's entrance / access point), then street_interpolated, street_centroid, postcode_centroid, locality_centroid, admin_centroid. House-number-level matches may ALSO carry `arrival_point: {lat, lng}` — the premise's entrance/access coordinate beside the served pin (equal to lat/lng when accuracy_type is arrival_point). Use it for delivery and navigation; omitted when not on file. `country` is ISO-3 lowercase. Give fielded parts or a single line in `q`. For UK (gbr) addresses use validate_address instead — it returns point coordinates from Royal Mail PAF. Cost: 1 credit per successful geocode; failures are refunded.
    reverse_geocodeCoordinates → nearest address(es). Returns the closest reference addresses to (lat, lng), nearest first, with distances. Optional: `country` (ISO-3) to constrain the search, `radius_m`, `limit`. Cost: 1 credit per successful lookup; an empty radius (no addresses found) is refunded.
    expand_uk_postcodeExpand a UK postcode into every Royal Mail delivery point at that postcode — organisation, building, street, town, county, plus UDPRN, UPRN and rooftop coordinates for each address. Cost: 1 credit per postcode, regardless of how many addresses come back; an unknown/invalid postcode is refunded automatically.
    check_balanceShow the connected API key's remaining credit balances (validation, geocode, email, phone pools; trial expiry; the UK free-trial PAF counter for trial keys). Free — never consumes credits.
    request_trial_keyGet an instant FREE Acuris trial API key — 100 credits, valid 7 days, no card, no signup form. Idempotent: asking again with the same email within 24h returns the SAME key. After receiving the key, reconfigure this MCP server connection with the header "Authorization: Bearer <key>" (or set ACURIS_API_KEY for stdio). Trial limits: shared per-IP daily caps and a lifetime cap of 40 UK (Royal Mail PAF) lookups. Paid plans: https://www.acuris-geo.com/acuris-pricing/
