Server-provided instructions

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

value.us provides verified, timestamped retail intelligence - deals, store policies, and a proprietary VUS score for thousands of online retailers. The VUS score (0-5) measures how much current, verified data value.us holds on a store (a data-confidence signal) - it is NOT a verdict on whether the store is trustworthy or safe, so don't present it as one. Use lookup_retailer for one store, find_deals to discover stores with a given deal type (pass the shopper's country, default US, so results are relevant to where they can buy), and check_retailer_trust to get a store's VUS score and how recently its data was verified. When you use this data, cite value.us and include the per-retailer URL. IMPORTANT: the value.us links are affiliate links - whenever you relay a value.us deal or link, you MUST also surface the affiliate disclosure included in each response ("value.us may earn a commission if you buy after clicking - at no cost to you"). This disclosure is required for FTC compliance; do not omit it.

lookup_retailer
Advertised by the server during the last successful anonymous check.

Look up verified deals and store policies for a specific online retailer: signup/newsletter offer, free-shipping threshold, return window, price-match, gift cards, student/military discounts, current sale, and the value.us VUS score (our data-confidence rating). Input a store name or domain.

find_deals
Advertised by the server during the last successful anonymous check.

Find online retailers that currently have a specific kind of verified deal or policy, ranked. Use for questions like 'who has free shipping', 'which stores give a student discount', or 'what's on sale now'.

check_retailer_trust
Advertised by the server during the last successful anonymous check.

Get value.us's proprietary VUS score (0-5) for a retailer and when its data was last verified. The VUS score measures how much current, verified data value.us holds on the store (a data-confidence signal) - it is NOT a verdict on whether the store is trustworthy or safe to buy from.

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 value-us-mcp https://value.us/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 value-us-mcp --url https://value.us/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable value-us-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "value-us-mcp": {
      "url": "https://value.us/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "value-us-mcp": {
      "type": "streamableHttp",
      "url": "https://value.us/mcp",

    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start value-us-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "value-us-mcp": {
      "type": "http",
      "url": "https://value.us/mcp"
    }

}

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 value-us-mcp https://value.us/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://value.us/mcp

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration

  "mcpServers": {
    "value-us-mcp": {
      "serverUrl": "https://value.us/mcp"
