Close API is an MCP server with 10 tools an agent can call, among them blocks_in_area, find_place, get_catalog. It answers at https://mcp.close.city/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 4 September 2026; the last check, on 17 October 2026, succeeded.
Walk, bike, and transit travel times from every US census block to nearby amenities.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
blocks_in_area | Per-block travel times for every census block in an area (metered: 1 token per returned row). Give place_geoid (from find_place) for a whole city, or center {lat, lon} + radius_m. Rows carry a numeric mode_id. Inputs: place_geoid, lat, lon, radius_m, type, mode |
find_place | Look up a US city or town by name (free, no key). Returns matches with their census place GEOID and centre point (lon/lat). The entry point: feed a GEOID to blocks_in_area, or a centre to walkability_summary. Inputs: query, limit |
get_catalog | List the travel modes and the destination-type taxonomy (free, no key). Use it to resolve type names to the numeric ids the other tools take. Modes are walk, bike, transit — there is no drive mode. |
get_token_balance | Check the token balance of the API key in use, without spending any tokens. Works even at a zero balance. Requires the Authorization bearer key. |
isochrone | The area reachable from a location within a time budget, as GeoJSON contours (metered: 10 tokens per contour). Give block_geoid or lat+lon. Defaults to a single 30-minute contour; ask for more only when needed (bodies can be large). Inputs: block_geoid, lat, lon, mode, minutes, contours |
join_close_plus | Get a Stripe Checkout URL for the Close+ membership ($10/month: 5,000 API tokens granted monthly plus member features on the close.city map). The user pays in their own browser: give them the returned URL and stop. Needs a fresh six-digit c Inputs: email, code |
nearby_pois | Nearby points of interest and the travel time to each, from a location (metered: 1 token per returned row). One origin: block_geoid or lat+lon; keep limit small to control spend and context size. Many origins (up to 250): block_geoids or po Inputs: block_geoid, lat, lon, block_geoids, points, type |
redeem_code | Complete sign-up with the six-digit code the user received, and return a new API key (shown once). Call request_sign_in first. The key grants 5,000 free tokens; store it and pass it as the Authorization bearer on future calls. Inputs: email, code, label |
request_sign_in | Start free sign-up for the user: email them a six-digit code. The user must read the code from their own inbox and give it to you, then call redeem_code. This is how an agent gets the user an API key (5,000 free tokens, no card). Inputs: email |
walkability_summary | Fastest travel time from a location to each destination category, by mode (metered: 1 token per returned row). One origin: block_geoid or lat+lon. Many origins (up to 250): block_geoids or points — one batch call and one rate-limit request, Inputs: block_geoid, lat, lon, block_geoids, points, mode |

It answered our last check on 17 October 2026 in 117 ms. Over 10 checks since 4 September 2026 it answered 10. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by close.city and served from mcp.close.city, the vendor's own domain: https://mcp.close.city/mcp.
10, as returned by the server's own tools/list on 9 September 2026: blocks_in_area, find_place, get_catalog, get_token_balance, isochrone, join_close_plus, nearby_pois, redeem_code, and 2 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.close.city/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
