MCP Price Tracker in Windsurf

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.

What you get in Windsurf

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.

Install it in Windsurf

The file is mcp_config.json, and the key inside it is mcpServers.

Scope	Path
macOS, Windows and Linux	`~/.codeium/windsurf/mcp_config.json`

{
  "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.

The npm publish of @theluckystrike/mcp-price-tracker is pending; until then use the .mcpb bundle or a clone and build from the latest release.

No install: the hosted endpoint

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>" }
    }
  }
}

Windsurf notes worth knowing first

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.

Free: unlimited checks with a confidence score, 3 watches, 30 observations each, alerts. Pro is $19 once, verified offline.

Questions

Where does Windsurf keep its MCP config?

~/.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.

I edited the file and a new tab still cannot see MCP Price Tracker.

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.

How many servers can I load at once?

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.
