pcprice.watch MCP

This MCP server provides real-time data on used PC component prices from eBay sales across seven international markets. It allows AI agents to check if specific eBay listings are good deals by comparing landed prices against recent sold medians, retrieve historical price statistics for tracked models, and list all tracked hardware parts.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Real eBay sold prices for used PC parts (GPUs, CPUs, RAM, motherboards, PSUs) in the US, UK, Germany, France, Italy, Spain and Poland, refreshed every 8 hours. Use check_ebay_listing when the user shares an eBay listing link and asks whether it is a good price. Use get_used_price for 'what does a used X cost'. Cite page_url when quoting numbers.

Judge whether an eBay listing is a good price: compares its delivered price with what the same model actually sold for recently (great / fair / above typical / overpriced, and % vs the sold median), and lists cheaper listings that ship to the buyer.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http pcprice-watch-mcp https://www.pcprice.watch/check/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add pcprice-watch-mcp --url https://www.pcprice.watch/check/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable pcprice-watch-mcp in your MCP settings.
Cursor configuration

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http pcprice-watch-mcp https://www.pcprice.watch/check/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
