# Tollbooth DPYC™ > MCP Monetization for BTC Entrepreneurs. Sound-money commerce without KYC or KYT. Pre-funded Bitcoin Lightning balances at the MCP tool layer. This file describes the Tollbooth DPYC service and lists the Authorities and Operators registered in the community registry — MCP servers that AI agents can connect to. Each endpoint follows the Model Context Protocol over SSE / streamable-HTTP and accepts pre-funded credit balances paid via Bitcoin Lightning. ## What Tollbooth DPYC is Tollbooth DPYC ("Don't Pester Your Customer") is an open-source Python SDK (`pip install tollbooth-dpyc`, Apache-2.0, patent pending) that lets an MCP server operator monetize tools with pre-funded Bitcoin Lightning balances. Identity is a Nostr keypair (npub) — no email, password, or KYC. Patrons pre-fund a satoshi balance once and consume tool calls without mid-session payment ceremonies. Operators run dynamic per-tool pricing: prices live in the MCP and are edited via standardized tool calls or the Pricing Studio iPad app, without recoding or redeploying. Authorities certify Operators and earn an ad valorem fee on credit purchases for providing registration, certification, and persistence. ## On this site - https://tollbooth-dpyc.com/#how — how the protocol works (six pillars) - https://tollbooth-dpyc.com/#quickstart — pip install plus minimal operator code - https://tollbooth-dpyc.com/#getting-started — prerequisites, five-step onboarding, roles (Citizen, Operator, Authority) - https://tollbooth-dpyc.com/#pricing-studio — the iPadOS pricing workbench - https://tollbooth-dpyc.com/#operators — live registry of member endpoints (also listed below) ## Authorities - [Lonnie VanZandt](https://dpyc-oracle.fastmcp.app/mcp): DPYC Oracle - concierge for the Don't Pester Your Customer network state More: https://cafe.tollbooth-dpyc.com/products/dpyc-oracle - [Tollbooth Authority New England](https://tollbooth-authority-newengland.fastmcp.app/mcp): DPYC Authority — New England sub-regional certifier More: https://cafe.tollbooth-dpyc.com/products/tollbooth-authority-new-england - [Lonnie-Authority](https://tollbooth-authority.fastmcp.app/mcp): DPYC Authority — certificate signing and operator registration More: https://cafe.tollbooth-dpyc.com/products/tollbooth-authority - [Tollbooth-Authority-NorthAmerica](https://tollbooth-authority-northamerica.fastmcp.app/mcp): DPYC Authority — North America regional certifier More: https://cafe.tollbooth-dpyc.com/products/tollbooth-authority-north-america ## Operators - [GoodEarth MCP](https://goodearth-mcp.fastmcp.app/mcp): MCP Operator registered under Authority npub157hmysd6sw7...

Identify yourself with a Nostr `npub` (public key). 2. Prove ownership on your connection: sign each request with the npub's key (NIP-98), or connect with OAuth and prove it once via `request_npub_proof` / `receive_npub_proof` — a Nostr DM challenge. 3. Pre-fund a credit balance via `purchase_credits` — pay the returned Lightning invoice. 4. Invoke any tool, passing your `npub`. Free tools (`session_status`, `check_balance`, `check_oauth_status`, `check_proof_status`, `request_npub_proof`, `receive_npub_proof`, `purchase_credits`, `check_payment`) never require credits. ## Source - https://github.com/lonniev/tollbooth-dpyc — the SDK (Apache-2.0, Patent Pending) - https://pypi.org/project/tollbooth-dpyc/ — the SDK on PyPI - https://github.com/lonniev/dpyc-community — community registry - https://github.com/lonniev/tollbooth-sample — reference Operator implementation - https://github.com/lonniev/tollbooth-sample/blob/main/GETTING-STARTED.md — full operator playbook - https://github.com/lonniev/tollbooth-pricing-studio — iPadOS pricing workbench ## Site - https://tollbooth-dpyc.com - https://mcps.tollbooth-dpyc.com — the MCPs collection: a page per service - Registry updated 2026-10-11T12:58:51Z - Snapshot taken 2026-10-21T12:47:41.868Z
