Walkability and pedestrian safety for any US address: scores, neighborhoods, deadly roads.

Overview

AI-generated overview

Remote MCP server that scores walkability and pedestrian safety for US addresses, cities and neighborhoods, with crash data and research.

What you can do
  • Score a single US address or coordinates for walkability and walking safety, with components and underlying metrics
  • Compare 2 to 10 locations side by side, or batch-score a list of up to 10 addresses
  • Look up precomputed walkability for a whole city or the most walkable neighborhoods within a city
  • Search 202,000+ US neighborhoods by region, home price, walkability and transit to shortlist places to live
  • Retrieve road corridors with recorded pedestrian deaths from federal crash records, and search published research articles with citable figures
When to use it
Useful when someone asks whether an address or neighborhood is walkable or car-free friendly, is comparing places to live, or needs sourced evidence about a dangerous street for a letter, story or grant application. Coverage is limited to the United States.
Requirements
A remote streamable HTTP endpoint; no sign-in or local runtime needed. Works keyless under a shared daily limit on full address scores, or with a free API key sent as the x-api-key header for 10,000 calls a month. Network access required.
Before you install
Every tool only reads data, but each scored location counts as one call against the allowance, so a list of ten costs ten. Keyless use shares a daily limit with other users. Scores are derived from third-party sources such as OpenStreetMap, NHTSA, Census, EPA and satellite imagery, and are US-only.

Installation

In SourceWeft

  1. Open SafeStreets in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Poseidon-t%2Fsafestreets/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

SafeStreets plugin

Walkability and pedestrian safety for any US address, for Claude and ChatGPT. Made by Streets & Commons.

The plugin connects your assistant to the SafeStreets MCP server at https://safestreets.streetsandcommons.com/mcp and adds three skills that tell the assistant how to use it well. It is free and needs no sign-in.

Tools

Every tool only reads data.

Skills

  • walkability-check: answers "is this address walkable?" with a verdict and the component that holds it back.
  • where-to-live-on-foot: narrows a move by region, budget and transit, then compares a shortlist.
  • street-safety-evidence: builds a sourced case about a dangerous street for a council letter, story or grant.

get_walkability_score

Score an address for walkability

Score a US location on how good and how safe it is to walk, from a street address or from latitude/longitude. Call this when someone asks whether a place is walkable, how safe it is to walk, whether they could live somewhere without a car, how a neighborhood compares to another on foot, or when evaluating a specific address or property for walkability or pedestrian risk. The server geocodes an address itself. Coordinates estimated from memory can land on a different place, which then gets a confident score of its own. When an address is given, the reply carries resolvedFrom with the address that was matched. Returns a JSON object: overallScore 0-100 composite displayScore the same score as 0-10, which is how SafeStreets presents it grade A to F tier plain label, e.g. "Very walkable", "Car-dependent" confidence 0-100, how much underlying data was available for this point reportUrl the full SafeStreets report for this point: map, metrics, PDF dataSources the sources that fed this specific result components four scored sub-dimensions, each with a 0-100 score and the individual metrics behind it: dailyReach errands reachable on foot streetSafety street design and pedestrian crash risk transitReach usable transit access walkingComfort shade, heat, air quality, surface plus networkDesign, which carries its metrics (network density, intersection density, block length, dead-end ratio) but reports score 0 at weight 0, so it does not contribute to the composite. Read its metrics, not its score. The keys safety, environmentalComfort and densityContext are backward-compatibility aliases of streetSafety, walkingComfort and dailyReach. They duplicate those objects

Parameterslatlonaddress

compare_locations

Compare locations for walkability

Score 2 to 10 US locations and say how they differ. Use this for "which of these is the most walkable", choosing between addresses, or any question that puts places side by side. Give addresses or coordinates, and a label for each if you want the results matched back to your own names. Returns every location ranked, the best and worst, the spread between them, and the gap on each component. The per-component gap is usually the answer: two places can reach the same composite for opposite reasons, one with errands close by and dangerous streets, the other the reverse. A location that cannot be resolved is reported in errors and the rest are still scored. Each location counts as one call against your allowance.

Parameterslocationsrequired

score_many

Score a list of locations

Score up to 10 US locations in one request. Use this for a list: properties, branches, listings, sites. Each location counts as one call against your allowance, so a list of ten costs ten. A location that cannot be resolved is reported in errors rather than failing the request.

Parameterslocationsrequired

get_city_walkability

City walkability score

Walkability score for a whole US city, precomputed. Instant, no analysis. Use this for "how walkable is Houston" rather than scoring a point inside it. Returns the 0-100 composite, the same score as 0-10, the tier, and the four components. Covers 203 cities; a city not in the set returns null, which means not covered rather than not walkable.

Parameterscityrequired

find_walkable_neighborhoods

Most walkable neighborhoods in a city

Neighborhoods inside a US city, ranked most walkable first, precomputed. Use this for "which part of Chicago should I live in without a car". Returns up to 25 neighborhoods, each with its 0-10 score, tier and components. Covers 749 neighborhoods across the cities analysed so far, so an empty list means that city has not been broken down yet, not that it has no walkable areas.

Parameterscityrequiredlimit

search_neighborhoods

Search US neighborhoods

Ranked neighborhood search across every US neighborhood (202,000+), for "where should I move" questions. Use this when someone is relocating and has not picked a town yet: filter to a county set, a metro, a state, a home-price ceiling or a walkability floor, then rank by walkability, transit, zero-car share, demand or home value. Each row carries median home value, median income, price-to-income ratio, commute mode shares, zero-car household share, and where available year-over-year home value growth and property tax rate — so walkability can be read alongside what living there costs. Counties are addressed by 5-digit state+county FIPS codes because county names repeat across states (there are Delaware Counties in PA, OH, NY and IN). Example: Chester PA 42029, Delaware PA 42045, Montgomery PA 42091, New Castle DE 10003. walkabilityIndex is the EPA National Walkability Index on its 1-20 scale, with a national percentile beside it, and sort_by "walk" ranks on it. It is a different scale from the 0-100 SafeStreets score, which comes from scoring one address.

get_dangerous_corridors

Roads where pedestrians were killed

Road corridors where pedestrians were actually killed, from federal crash records. Source: NHTSA FARS 2022-2024 (PER_TYP=5, INJ_SEV in 4,6). Each corridor carries the road name, the city, the total pedestrian deaths and a per-year breakdown, so a claim can be checked rather than taken on trust. Give either a city, or a lat/lon with an optional radius. Use this when someone asks which roads are dangerous, where crashes happen, or wants evidence for a specific street. These are recorded deaths, not a model or a prediction: a road absent from the list had no recorded pedestrian fatality in the period, which is not the same as being safe.

ParameterslatloncitylimitradiusKm

search_insights

Search SafeStreets research

Search SafeStreets' published research on walkability, street design and pedestrian safety. Returns the article title, summary, URL and its published questions and answers, so a finding can be quoted and linked rather than paraphrased from memory. 32 articles, each built on named public sources. Use this when someone asks what the evidence says, wants a figure they can cite, or asks a general question about walkability that is not about one specific location.

Score

100% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
