# C14-MMS

> Star Wars Galaxies auction market data. Humans use the Price Checker, Market Analysis chatbot, and Historical Data viewer. Agents talk to the same SQLite database over MCP — deterministic tools, no second LLM.

C14-MMS (Market Messaging Service) is at https://pricecheck.c14.software. REST and MCP are public. The database is read-only. Price-per-unit is BuyNowPrice / Quantity. Item names are fuzzy (LIKE).

## Pages

- [Home](https://pricecheck.c14.software/): Price Checker, Market Analysis, Historical Data.
- [Add this to your agent](https://pricecheck.c14.software/agents): How to connect Cursor, Claude Code, or any MCP client. Human-readable.
- [Price Checker](https://pricecheck.c14.software/pc.html): Fast current + historical price lookup.
- [Market Analysis](https://pricecheck.c14.software/mms.html): Natural-language chat that writes SQL (OpenRouter). Agents should use MCP tools instead of this page.
- [Historical Data](https://pricecheck.c14.software/historical.html): Monthly aggregates from AuctionHistoricalData.
- [About](https://pricecheck.c14.software/about.html): Dataset coverage.

## For agents

- [MCP server](https://pricecheck.c14.software/mcp): Model Context Protocol, stateless Streamable HTTP (`2026-07-28`). POST JSON-RPC only. GET/DELETE return 405 (no SSE, no sessions). Dual-stack: modern clients use `server/discover` plus `MCP-Protocol-Version` / `Mcp-Method` / `Mcp-Name` headers; current Cursor may send `initialize` (no `Mcp-Session-Id` is minted).
- Auth: none. Anonymous. Same as REST.
- Tools (read-only, same SQL as the web app, no OpenRouter hop): `price_check` (prefer this for “what does X cost”), `historical_search`, `historical_months`, `query_auctions` (SELECT/WITH only, 1000-row cap), `health`.
- Tables: `Auctions` (live/seen listings: ItemName, Location, OwnerName, MinBid, HighBid, BuyNowPrice, Quantity, ExpiryTime, FirstSeenUtc, LastSeenUtc, …) and `AuctionHistoricalData` (monthly aggregates: ItemName, MonthYear, AvgPrice, MinPrice, MaxPrice, NumAuctions, DistinctSellers). `price_check` filters BuyNowPrice < 555555555 and uses a 6-month “current” window.
- Do not wrap `/api/chat` or the SSE price-check chatbot. Call the tools.
