What your AI can do with Close API
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “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:.”
“Use “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.”
“Use “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 la.”
“Use “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+l.”
How secure is the Close API MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Close API holds up.
Official endpoint
Operated by Close API (close.city) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Close API adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Pick Close API
Choose Close API in the gate directory. No sign-in needed.
Use it anywhere
Close API's tools are live in every AI client you've connected — with rules and logging built in.

The actual tools Close API exposes
Fetched live from the official endpoint and re-checked daily by gate — not marketing copy.
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:
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
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 la
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+l
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.
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
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
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

Who runs the Close API MCP server?
The Close API MCP server at a glance
https://mcp.close.city/mcpQuestions, answered
Is there an official Close API MCP server?
Yes — Close API operates its own remote MCP server at mcp.close.city. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Close API to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Close API in the directory. No account or sign-in is needed. From then on, Close API's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Close API runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Close API MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect Close API in minutes. No credit card required.
