Check and watch product prices on ordinary shop pages. It reads the price out of a product page from JSON-LD, microdata, Open Graph or visible markup, normalises 1.299,00 EUR and 1,299.00 USD alike, and keeps a per-watch history.
Cascade browses, so the watch list is the reason to install this rather than the single lookup, and the watch list is the half a browser cannot do.
| You say | Tool |
|---|---|
| What does this cost right now: <product url>? | price_check |
| Watch that page and alert me if it goes under 40. | watch_add |
| Has anything I'm watching hit its target or dropped a lot? | alerts_pending |
One measured limitation: with a general web fetcher available, a client sometimes answers a price question by fetching the page itself, so nothing is stored. Name the tracker in the sentence.
The file is mcp_config.json, and the key inside it is mcpServers.
| Scope | Path |
|---|---|
| macOS, Windows and Linux | ~/.codeium/windsurf/mcp_config.json |
If you also run Claude Desktop, the shortest path there is one click: price-tracker.mcpb
from the bundle catalog opens as an extension, with no JSON and no terminal.
Windsurf reads its own config, so here it is:
The config block:
{
"mcpServers": {
"price-tracker": {
"command": "node",
"args": ["/absolute/path/to/mcp-servers/servers/price-tracker/dist/index.js"]
}
}
}The node command above wants a built file. From a clone, once:
git clone https://github.com/theluckystrike/mcp-servers.git
cd mcp-servers && npm install
npm run build -w packages/mcp-license -w servers/price-trackerThat writes servers/price-tracker/dist/index.js, and its absolute path is the one argument
the config needs.
The npm packages are not published yet, so the form below returns a 404 today. It is here because it is what the entry becomes the day the publish lands, with nothing else changed:
{
"mcpServers": {
"price-tracker": {
"command": "npx",
"args": ["-y", "@theluckystrike/mcp-price-tracker"]
}
}
}Save and reopen the MCP Servers list; Cascade picks it up without restarting the editor.
Nothing is published to npm yet, so the working install paths are the ones above: the .mcpb bundle from the bundle catalog, a clone and build, or the hosted URL.
The same server runs at https://mcp.zovo.one/mcp/price-tracker over MCP streamable HTTP, no install. Mint a free token with curl https://mcp.zovo.one/mcp/token, or use a Pro key. It has no filesystem, so a file comes back as a one-hour download link.
{
"mcpServers": {
"price-tracker": {
"url": "https://mcp.zovo.one/mcp/price-tracker",
"headers": { "Authorization": "Bearer <token>" }
}
}
}Read this first: mcp_config.json applies to the legacy Cascade agent only. The Devin Local agent, the default for new tabs, takes its servers from the Devin CLI config files, so a correct entry here can still be invisible in a fresh tab. The other hard number is a cap: Cascade reaches at most 100 tools at once, and every enabled server spends from it.

~/.codeium/windsurf/mcp_config.json, under mcpServers. Reach it from the MCPs icon at the top right of the Cascade panel, or Devin Settings, Cascade, MCP Servers.
That file applies to the legacy Cascade agent only. The Devin Local agent, the default for new tabs, reads its servers from the Devin CLI config files instead. Check which agent the tab runs.
Cascade reaches at most 100 tools at any one time, and every enabled server spends from that single budget. MCP Price Tracker contributes 10 tools, so keep the enabled list short rather than counting servers.
