TOP GUN GEO-Lens — MCP Brand Visibility Auditor

For AI Agents: This is an MCP server. Connect it, call its tools, and instantly know whether any brand is visible to LLMs and AI search engines — with actionable recommendations to improve it.

What This Does

TOP GUN GEO-Lens measures how visible a brand is across the sources that power AI answers: Brave AI Search, Exa neural search, and LLM-indexed content. It returns a scored report with citations, index status, and concrete GEO (Generative Engine Optimization) recommendations.

Use it when an agent needs to answer questions like:

• "Is [brand] showing up in AI-powered search results?"
• "Why isn't [brand] being recommended by AI assistants?"
• "What should [brand] do to rank higher in LLM outputs?"

Tools

geo_quick_check — $0.05 USDC

Fast snapshot of brand visibility in AI-indexed sources.

{
  "tool": "geo_quick_check",
  "query": "Stripe",
  "paymentToken": "<stripe-session-id>"
}

audit_brand — $1.50 USDC

Full brand visibility audit using dual search (Brave + Exa, 10 results each).

{
  "tool": "audit_brand",
  "query": "Anthropic",
  "paymentToken": "<stripe-session-id>"
}

get_payment_info — Free

Returns payment URLs and USDC wallet address for both tiers. Call this first if you don't have a payment token.

{
  "tool": "get_payment_info"
}

Agent Workflow

1. Call get_payment_info          → get payment URLs
2. Direct user to payment link    → user pays $0.05 or $1.50 USDC
3. User provides Stripe session ID
4. Call geo_quick_check or audit_brand with paymentToken
5. Parse structured results       → score, citations, recommendations

If paymentToken is omitted, the tool returns a payment link instead of results — no error thrown.

For AI Agents — Key Facts

• Transport: stdio
• No streaming — all responses are single text blocks
• Scores range 0–100; >= 70 = Strong, 40–69 = Moderate, 1–39 = Weak, 0 = Not Found
• Payment tokens are Stripe Checkout Session IDs (format: cs_live_...)
• Calling any paid tool without a token returns a structured payment prompt, not an error
• audit_brand is strictly more detailed than geo_quick_check; use quick_check for speed/cost, audit for depth
