MCP support

Provides read-only MCP tools for querying public On the Cheap network sites. Most tools require a site key for the city or national site being queried.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config

Environment variables to set
COTC_BASE_URLOptional override for the Charlotte On The Cheap base URL. The site is public; no credentials are required.

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Details

From the project README

onthecheap-mcp

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.

Install

npx onthecheap-mcp

Or as a Claude Code plugin:

/plugin marketplace add chrischall/onthecheap-mcp
/plugin install onthecheap-mcp

Choosing a city

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:

KeySiteArea
charlotteCharlotte On The CheapCharlotte, NC
denverMile High on the CheapDenver, CO
atlantaAtlanta on the CheapAtlanta, GA
chicagoChicago on the CheapChicago, IL
columbusColumbus on the CheapColumbus, OH
seattleGreater Seattle on the CheapSeattle–Tacoma

portlandPortland Living on the CheapPortland, OR

triangleTriangle on the CheapRaleigh / Durham / Chapel Hill
nationalLiving On The CheapUS-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.

Tools

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.

ToolWhat it does
otc_list_eventsEverything on a given day — time, price, venue. free_only filters to no-cost listings. Defaults to today.
otc_events_month_overviewDay-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_postsSearch articles by text, category, location and date range. Returns slim summaries by default.
otc_get_postOne article in full, as readable text or raw HTML. Accepts an id, slug, or URL.
otc_list_categoriesCategory ids and post counts, for filtering searches by topic.
otc_list_locationsLocal area ids and post counts, for filtering geographically.
otc_list_sitesThe cities in the network and their site keys. Takes no arguments.
otc_healthcheckConfirm one site is reachable; on failure error.kind is edge_blocked, http, timeout or transport.

Two things worth knowing

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.

Configuration

None. The city is a per-call site argument, not an environment variable, so there is nothing to set up before use.

Development

npm install
npm test
npm run build

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.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
