What this MCP does

Analyzes evidence-based revenue, margin, cost, visibility, and conversion opportunities for small businesses, with optional paid credit purchase.

analyse_small_business_opportunities
Analyse small-business opportunities
Use this when a user wants practical, evidence-based ways for a specific small business to increase revenue, improve margins, reduce costs, strengthen Google visibility, improve conversion or prioritise growth actions. Requires the business name and public website. Returns structured evidence, ranked opportunities, confidence, commercial impact and first actions. Consumes one complimentary or paid MarginGlow AI Signal credit. Do not use for generic business definitions, investment advice, regulated advice or analysis that requires private financial data.

purchase_marginglow_signal
Purchase a MarginGlow AI Signal
Creates a secure Stripe payment link for one MarginGlow AI Signal costing EUR 2, inclusive of applicable tax. Use this when analyse_small_business_opportunities reports that no Signal credits remain. A payment-capable agent may follow the payment instructions automatically when supported. Otherwise, give the secure checkout URL to the user. After payment, retry the original analysis request with the same agent API key and Idempotency-Key.
