Use CityWalk Plan in your AI assistant

CityWalk Plan is a Model Context Protocol (MCP) server, so Claude, ChatGPT, and other AI assistants can build a real day-by-day walking itinerary for you — right inside the chat. Free, public, no API key.

Remote MCP endpoint https://citywalkplan.com/api/mcp
Streamable HTTP · public · no auth · no API key

Listed in the official MCP registry as com.citywalkplan/planner.

What you can ask

The server exposes three tools. Your assistant calls them for you — you just ask in plain language.

list_cities

The cities CityWalk Plan covers, grouped by region.

e.g. “Which walkable cities does CityWalk Plan support in Europe?”
plan_city_walk

A day-by-day walking route for a city — by number of days and pace (easy / balanced / packed), with optional must-see places. Real, hand-curated stops grouped by neighborhood.

e.g. “Plan a 3-day walking trip in Lisbon at an easy pace.”
get_place

Details for one place: type, neighborhood, suggested duration, coordinates, Wikipedia link.

e.g. “Tell me about Sensō-ji in Tokyo.”

Add it to Claude

Custom connectors are available on Claude Free, Pro, and Max (Free is limited to one).

  1. In Claude.ai, open Settings → Customize → Connectors.
  2. Click +, then Add custom connector.
  3. Paste https://citywalkplan.com/api/mcp and click Add. Leave the OAuth fields blank — no authentication is needed.
  4. In a chat, open the + menu → Connectors, enable CityWalk Plan, and ask it to plan a walk.

Add it to ChatGPT

Full MCP connectors run in developer mode on ChatGPT (web) for Plus, Pro, Business, Enterprise, and Edu plans.

  1. In ChatGPT on the web, open Settings → Apps & Connectors → Advanced settings and turn on Developer mode.
  2. In Connectors, choose Create / Add, name it CityWalk Plan, and paste https://citywalkplan.com/api/mcp with No authentication.
  3. Enable the connector in a conversation and ask ChatGPT to plan a walking itinerary with CityWalk Plan.
Any MCP client works the same way — Claude Desktop, MCP-enabled IDEs, and agent frameworks all just need the URL https://citywalkplan.com/api/mcp.

Example prompts

Every itinerary comes with a citywalkplan.com link, so you can open the route on a map, reorder or remove stops, share it, or export an offline copy.

FAQ

Is it free?

Yes — the MCP endpoint is public and free, with no API key, no account, and no sign-up. The planner is supported by optional affiliate booking links.

Which AI assistants can use it?

Any MCP client: Claude.ai (custom connectors), ChatGPT (developer mode), Claude Desktop, MCP-enabled IDEs, and agent frameworks. Add the remote URL https://citywalkplan.com/api/mcp.

Do I need an API key or login?

No. The server uses Streamable HTTP with no authentication, so you only paste the URL — no key, no OAuth, no account.

Is it in the official MCP registry?

Are the places real?

Yes. Every result links back to citywalkplan.com, where you can open it on a map, reorder or remove stops, share a link, or export an offline copy.
