What You'll Need

Set these up before or after installing:

LND REST API URL (recommended wallet; pair with LND_MACAROON). A wallet is optional — without one, free tools and marketplace search still work; paid calls return their payment challenge.Optional

Environment variable: LND_REST_HOST

Hex-encoded macaroon for LND (use a pay-scoped macaroon in production). Required with LND_REST_HOST.Required

Environment variable: LND_MACAROON

Nostr Wallet Connect string — easiest setup, works with CoinOS, Alby Hub, Zeus, and more. Alternative to LND.Required

Environment variable: NWC_URI

LNbits instance URL (pair with LNBITS_ADMIN_KEY). Alternative wallet.Optional

Environment variable: LNBITS_URL

Admin API key for LNbits. Required with LNBITS_URL.Required

Environment variable: LNBITS_ADMIN_KEY

Phoenixd HTTP API URL (pair with PHOENIXD_PASSWORD). Alternative wallet.Optional

Environment variable: PHOENIXD_URL

HTTP password for Phoenixd. Required with PHOENIXD_URL.Required

Environment variable: PHOENIXD_PASSWORD

Maximum sats the server may spend per session (process lifetime), across ALL sources. Unset = unlimited; 0 = free tools only. The config file's budget.sat takes precedence.Optional

Environment variable: BUDGET_SATS

Optional bolthub API token, used only by the deploy_node / node_status Node Launcher tools.Required

Environment variable: BOLTHUB_AUTH_TOKEN

bolthub SDK

Source code for every publicly published bolthub.ai package — the npm @bolthub/* scope and the bolthub / bolthub-verify PyPI packages.

bolthub is a payment layer for agent-to-tool commerce: charge agents for your MCP tools and APIs per call, settling on the rail you choose (Lightning today, stablecoins next), with bolthub never in the funds path. These packages are the open-source side of that: the tool-payment SDK, payment clients, MCP servers, a CLI, and origin-verification middleware.

Package	Registry	Directory	What it is
`@bolthub/pay`	npm	`packages/pay`	Tool-payment SDK — price an MCP tool or HTTP endpoint (`createPaywall`), pay for tools within a budget (`PayingClient`); rails: L402, x402, facilitator
`@bolthub/agent`	npm	`packages/agent`	L402 payment client — wallet adapters (LND, LNbits, Phoenixd, NWC, WebLN), 402 challenge handling, session cache
`@bolthub/mcp-registry`	npm	`packages/mcp-registry`	MCP server exposing the whole bolthub marketplace to AI agents
`@bolthub/mcp-bridge`	npm	`packages/mcp-bridge`	MCP server for a single bolthub gateway (one tool per endpoint)
`@bolthub/cli`	npm	`packages/cli`	Terminal client for the marketplace
`@bolthub/verify`	npm	`packages/verify`	Gateway signature verification middleware (Express/Fastify/Node)
`bolthub`	PyPI	`packages/agent-python`	Python L402 client
`bolthub-verify`	PyPI	`packages/verify-python`	Python gateway signature verification (Flask/Django/FastAPI)

packages/shared is internal (never published); it is here because @bolthub/mcp-bridge bundles it.

Relationship to the bolthub platform

The bolthub platform (gateway, API, web app) lives in a private monorepo. The SDK packages above are developed there and synced to this repository, which is the publish origin: releases are tagged here and built + published by CI with npm provenance, so what's on npm is verifiably built from this public source.

Issues and PRs are welcome here. Accepted changes are applied to the monorepo first, then sync back out with the next release.

Verifying what you install

Published dist/ bundles are built with Bun from this source and ship source maps with embedded sources, so the tarball itself is readable.

# provenance: confirm the tarball was built from this repo by GitHub Actions
npm audit signatures

# or rebuild and compare yourself
git clone https://github.com/signaltech-org/bolthub-sdk
cd bolthub-sdk && bun install
cd packages/mcp-registry && bun run build

See SECURITY.md for the trust model (what touches your wallet credentials and what doesn't) and how to report vulnerabilities.

Development

bun install
bun test

Each TypeScript package builds with bun run build from its directory (@bolthub/agent must be built before the packages that bundle it).
