What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

  • search_library

    Find public-records sources (datasets, portals, registers, reports) by question or keywords. Use `place` to include everything covering a place, from the city up to federal and global sources. Returns the publisher, how to get the data (API endpoint or page), update rate, last up

  • get_source

    Full details of one source by id: publisher, original link, API endpoint, formats, update rate, last update, licence, location detail, check status and notes.

  • list_places

    The atlas: world, countries, states, counties and cities, with their ids. Filter by parent id (e.g. 'us' for US states) or kind.

  • list_departments

    The 15 departments (shelves) every source sits on, with what each covers.

  • list_gaps

    Records people need that the library doesn't hold yet, or that no agency publishes. Check this before telling a user a record doesn't exist.

  • search_records

    The records SOS.city reads from agencies' open data, one row each: building permits, code-enforcement cases, inspections, certificates of occupancy, new business registrations, grants, weather alerts, earthquakes, US wildfires (NIFC) and SCE power shutoffs. Filter by place, kind,

  • request_record

    Ask SOS.city to find a public record that isn't in the library. It joins the gap board; give an email to hear back. Never for locating or profiling a person.

  • get_store

    The SOS.city data store: what's free, what costs credits (1 credit = 1 cent), credit packs, city data packs, building records and deep searches, and every way to pay (credits with an API key, x402 USDC, or a Stripe link for a person). Shows the caller's credit balance when an API

  • buy

    Starts a one-time purchase and returns a Stripe Checkout link for the person who pays, plus a status_url to poll. product: credits_1k ($10), credits_10k ($79) or city_pack ($29, needs place). The person must agree to the data-use terms (no screening or profiling people): pass agr

  • get_city_pack

    Every source that covers one place (with publisher, original link, licence and reuse terms) plus a year of records whose sources allow reuse. Costs 2900 credits from the API key's balance. Without credits, use buy (product city_pack) or the REST URL with x402.

Common questions

Is SOS.city public record safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?
