AgentPay Gateway MCP

One MCP installation gives your agent access to 42 backend servers — web search, legal analysis, domain intelligence, QR codes, email verification, SEC filings, patent lookup, and more — with per-call credit billing and one API key instead of 42.

What your agent can do

• Call any of the 90+ tools across 42 specialized backend servers through a single MCP endpoint — no separate accounts or API keys per service
• Pay per call using a credit system: most tools cost 1–3 credits, compute-heavy tools (contract analysis, SEO audit, legal contract generation) cost 5–8 credits
• Check remaining daily credits and account status at any time via gateway_info
• Get a Stripe checkout link to upgrade when credits are exhausted — the server returns the URL directly
• Run in demo mode locally (no database) or full mode with Supabase-backed credit ledger and Stripe billing
• Deploy via Docker with environment variables for a production-ready self-hosted gateway

Installation

Requires: Python 3.10+, mcp, httpx, anyio packages.

pip install mcp httpx anyio

The gateway runs as an HTTP server (not stdio). It must be started separately before connecting your MCP client.

# Demo mode — no database required
python server.py --port 8000

# Production mode — set env vars first
export SUPABASE_URL=https://your-project.supabase.co
export SUPABASE_SERVICE_KEY=your-service-key
export STRIPE_API_KEY=sk_live_...
export STRIPE_CHECKOUT_LINK=https://buy.stripe.com/...
python server.py --port 8000
