Lunoo MCP

An MCP server that provides access to Lunoo's evidence-aware rankings for over 230,000 products and services. It allows AI agents to resolve topics to ranking slugs, retrieve top-ranked items with scores and citations, and fetch structured item data including pros, cons, and FAQs.

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.

Lunoo is a public, read-only rankings service. Resolve a natural-language request with find_niche first when possible, select the closest verified niche slug using its match explanation and confidence, then call get_rankings with that slug. get_rankings can resolve natural language itself when needed. Return ranked results using only the scores and descriptions from the tool response, include the returned Lunoo URLs, and never invent items, scores, slugs, or citations. Use get_item only when the user asks for details about a ranked item.

Tools

3 advertised

find_niche
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Resolve a natural-language ranking request to one or more verified Lunoo niche slugs. Pass the user's request instead of guessing a slug. It handles common aliases, typos, and use-case terms, and returns item counts, match explanations, confidence, and tracked Lunoo URLs. Unsupported or unclear requests return an error instead of an unrelated fallback. Choose the closest returned slug, then call get_rankings with that exact slug. Never invent a niche slug or ranking.

get_rankings
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Fetch ranked Lunoo results for a verified niche slug or natural-language request. It returns rank, score, description, confidence, and a canonical Lunoo URL for every item, plus the selected niche and resolution explanation. Prefer calling find_niche first, but this tool can resolve natural language itself. Cite the returned ranking URL and do not invent items, scores, or slugs.

Use this after a ranking result when the user wants details about one item. Pass the exact item slug from a Lunoo result or URL. It returns the canonical Lunoo URL for the item and public structured metadata. This is read-only and must not be used to invent rankings that were not returned by get_rankings.

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 lunoo-mcp https://lunoo.com/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 lunoo-mcp --url https://lunoo.com/mcp

Cursor

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

VS Code

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

Windsurf

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