Tollbooth Authority — North America

The North American on-ramp to the Lightning turnpike.

Identity: npub1zummm5awn88kw2hz6deeyjprpw0fzuv9rvzrxf3vu453yyqzvdss49xd2t Parent: DPYC Prime Authority (npub1l94pd…mq8pf) Peer Authorities under Prime: tollbooth-authority (Lonnie-Authority) Sub-Authority: tollbooth-authority-newengland Service: https://tollbooth-authority-northamerica.fastmcp.app/mcp Neon region: aws-us-west-2 (Oregon)

A peer-level Authority under DPYC Prime, serving North American operators. Operators may choose this Authority to keep certification latency and audit trails in-region.

The metaphors in this project are drawn with admiration from The Phantom Tollbooth by Norton Juster, illustrated by Jules Feiffer (1961). We just built the payment infrastructure.

Architecture

This repository is a thin consumer of the tollbooth-dpyc wheel's tollbooth.authority extension (wheel ≥ 0.22.1). The entire deployable surface lives in src/tollbooth_authority/server.py (~90 lines): a FastMCP instance, an OperatorRuntime, and two register_*_tools(mcp, runtime) calls. Onboarding state machine, Schnorr signer, replay tracker, Neon tenant provisioning, and the 16 Authority @tool definitions are wheel-resident and shared with every other Authority MCP in the ecosystem.

For the protocol semantics, certificate format (Schnorr/NIP-33 kind 30079), fee cascade, registry enforcement, and tool catalog, see the canonical tollbooth-authority README — this repo is identical in behavior, distinct only in identity, region, and Neon tenant.

Deploy

Two secrets required by Horizon:

Everything else — BTCPay credentials for the cashier, operator credential templates — arrives via Secure Courier post-deploy (see docs/how-to-add-authority.md in the community repo).

The DPYC Ecosystem

DPYC is a federation of independent, SSE-based MCP servers sharing one Lightning-funded economy. This Authority certifies operators across the network. Sibling repos:

Core & governance

• tollbooth-dpyc — shared Python SDK (crypto, vault, auth, pricing, audit)
• dpyc-community — governance registry (members, rulebook, CI validation)
• dpyc-oracle — free community concierge (membership, onboarding, tax-rate questions)
• tollbooth-authority — canonical certification Authority
• tollbooth-sample — reference Operator implementation
• tollbooth-pricing-studio — native pricing editor (Swift/iOS)

Operators (paid MCP services)

• cypher-mcp — monetized graph answers via named Cypher templates over Neo4j/AuraDB (certified under this Authority)
• schwab-mcp — Charles Schwab brokerage data
• thebrain-mcp — TheBrain knowledge-graph access
• excalibur-mcp — X/Twitter posting
• taxsort-mcp — tax classification + Cloudflare Pages UI
• optionality-mcp — options analytics

Utilities & advocates

• tollbooth-oauth2-collector — shared OAuth2 callback collector
• tollbooth-shortlinks — URL shortener
