The full upstream README, mirrored here for reference. Install config, tool schemas, adoption signals, and an original overview live on the Onthecheap MCP listing page.
MCP server for the On the Cheap network — local guides to free and cheap things to do across 14 US cities. Daily event listings with times, prices and venues, plus a searchable archive of deals and guides.
Developed and maintained by AI (Claude Code). Use at your own discretion.
No credentials required. Every site is public, so the server reads them server-side over plain HTTPS. There is nothing to configure beyond which city you want, and no browser extension involved.
Or as a Claude Code plugin:
One server reads the whole network. Every tool takes a site argument
naming the city to read — there is no default and no configuration step:
| Key | Site | Area |
|---|---|---|
charlotte | Charlotte On The Cheap | Charlotte, NC |
denver | Mile High on the Cheap | Denver, CO |
atlanta | Atlanta on the Cheap | Atlanta, GA |
chicago | Chicago on the Cheap | Chicago, IL |
columbus | Columbus on the Cheap | Columbus, OH |
seattle | Greater Seattle on the Cheap | Seattle–Tacoma |
kansascity | Kansas City on the Cheap | Kansas City |
miami | South Florida on the Cheap | Miami / Broward / Palm Beach |
orlando | Orlando on the Cheap | Orlando, FL |
portland | Portland Living on the Cheap | Portland, OR |
richmond | RVA on the Cheap | Richmond, VA |
southernmaine | Southern Maine on the Cheap | Southern Maine |
triangle | Triangle on the Cheap | Raleigh / Durham / Chapel Hill |
national | Living On The Cheap | US-wide deals (no local events calendar) |
Common aliases work too — milehigh, raleigh, rva, kc, southflorida.
otc_list_sites reports the same list.
site is required rather than defaulted on purpose: a server that quietly fell
back to one city would answer a question about Denver with Charlotte's data and
give no sign anything was wrong. An unknown key is refused with the valid ones
listed.
All tools are read-only. Every tool except otc_list_sites takes a required
site argument. The two event tools reject national, which has no local
events calendar — it is still searchable via the other tools.
| Tool | What it does |
|---|---|
otc_list_events | Everything on a given day — time, price, venue. free_only filters to no-cost listings. Defaults to today. |
otc_events_month_overview | Day-by-day counts for a month, to find the busiest days. Each day's list is a preview; total is the real count. |
otc_search_posts | Search articles by text, category, location and date range. Returns slim summaries by default. |
otc_get_post | One article in full, as readable text or raw HTML. Accepts an id, slug, or URL. |
otc_list_categories | Category ids and post counts, for filtering searches by topic. |
otc_list_locations | Local area ids and post counts, for filtering geographically. |
otc_list_sites | The cities in the network and their site keys. Takes no arguments. |
otc_healthcheck | Confirm one site is reachable. |

Retired deals are excluded by default. Each site parks expired offers in an
expired category, so searches skip them and you don't get deals that no
longer exist. Pass include_expired: true to search the archive. The category's
id differs on every site, so it's resolved by slug at request time — a
hardcoded id silently disables the filter elsewhere.
Category and location ids are per-site. Each site is a separate WordPress
install, so id 13 is a different category on every one of them. Resolve ids
against the same site you then search — an id borrowed from another city will
filter to something unrelated rather than error.
Month overviews are previews, with honest counts. The calendar shows at
most four listings per day. otc_events_month_overview reports each day's
true total alongside the preview — call otc_list_events with a date for the
complete schedule.
None. The city is a per-call site argument, not an environment variable, so
there is nothing to set up before use.
See docs/OTC-API.md for the verified data surface,
including the events calendar's US M-D-YYYY date routing (an ISO date is
silently parsed as 1970), the month-view truncation, and why term ids are never
hardcoded.
