sightvane-mcp

An MCP server that turns any AI assistant into an SEO + GEO measurement instrument.

Sightvane measures the two ways buyers find you now: classic search (technical site health, keywords, rankings, performance) and generative engines (whether ChatGPT, Claude, Perplexity, and Google AI Overviews mention your brand and cite your pages). This server exposes the full instrument as 16 Model Context Protocol tools, so an assistant like Claude can run complete SEO sessions: crawl a site, research keywords, sample AI-answer panels, and report visibility scores, in one conversation.

Why this exists

• Zero fixed cost. The crawler, keyword engine (live autocomplete graph), and assistant-driven GEO sampling need no API keys at all. Optional free/cheap keys unlock PageSpeed, domain authority, SERP snapshots, and multi-engine sampling.

• The assistant IS the answer engine. The claude-session loop lets the assistant answer realistic buyer prompts naturally, record its own answers, and measure the brand mentions inside them. One sampling engine, effectively free.

• Local-first. Your data and keys stay in a local JSON store. Nothing syncs anywhere.

Quickstart

git clone https://github.com/BaseHoss/sightvane-mcp.git
cd sightvane-mcp && npm install

Register with Claude Code:

claude mcp add sightvane -- node /path/to/sightvane-mcp/src/index.js

Or in any MCP client config:

{
  "mcpServers": {
    "sightvane": { "command": "node", "args": ["/path/to/sightvane-mcp/src/index.js"] }
  }
}

Then ask your assistant: "run an SEO session on example.com".

The 16 tools

The honest-sampling rule

GEO numbers are only meaningful if the sampling is unbiased. When an assistant answers panel prompts for sightvane_geo_record, it must answer exactly as it would for any user, never deliberately mentioning the measured brand. A flattering panel is a false map.

Optional keys (environment or the Sightvane app's Settings)

All engines degrade gracefully with zero keys. Optional: Google PageSpeed, OpenPageRank (free), serper.dev (free tier), OpenAI / Anthropic / Perplexity / Gemini for multi-engine GEO sampling.

Data lands in ./data by default; set SIGHTVANE_DATA to point elsewhere (for example, at the Sightvane dashboard's data directory so results appear there live).
