- notes: Alpha. Repo release v0.2.0 on 2026-10-23. MCP is `wavecli mcp serve`. Receive-only macaroons are `wavecli bakemacaroon`. Retried requests do not pay twice. Also https://wavelength.lightning.engineering/llms-full.txt and https://github.com/lightninglabs/wavelength/releases/tag/v0.2.0. The license string is the one recorded for that GitHub repo in the 2026-10-24 library candidate.

## Alby / NWC

- id: alby-nwc
- custody: null
- mcp_support: true
  - source: https://github.com/getAlby/mcp
  - verified_at: 2026-10-20
- l402_support: null
- receive_only_permissions: null
- payment_idempotency: null
- limits: null
- fees: null
- license: null
- llms_txt_url: null
- docs_url: null
- source_url: https://github.com/getAlby/mcp
- last_verified: 2026-10-20
- notes: Library entry getalby-mcp-github (verified 2026-10-20) says this repository is an MCP server that connects an LLM agent to a Lightning wallet over Nostr Wallet Connect. NIP-47 (nostr-nip-47-wallet-connect, verified 2026-10-20) defines pay_invoice and make_invoice and does not state custody, L402, receive-only permissions, payment idempotency, limits, fees, or an llms.txt URL. Alby Hub v1.24.3 (verified 2026-10-21) is described as a self-hosted node; that phrase is not applied to this row because NWC also reaches other wallets. The js-sdk v8.1.0 recordEvent handler is request deduplication, not a stated payment-idempotency guarantee, so payment_idempotency stays null.

## Voltage

- id: voltage
- custody: null
- mcp_support: null
- l402_support: null
- receive_only_permissions: null
- payment_idempotency: true
  - source: https://github.com/voltagecloud/voltage-cli
  - verified_at: 2026-10-23
- limits: null
- fees: null
- license: MIT
  - source: https://github.com/voltagecloud/voltage-cli
  - verified_at: 2026-10-23
- llms_txt_url: null
- docs_url: null
- source_url: https://github.com/voltagecloud/voltage-cli
- last_verified: 2026-10-23
- notes: Library entry voltage-cli (verified 2026-10-23) quotes the README: the CLI creates wallets and receives and sends Lightning payments, and on-chain payments where enabled, from a terminal, a script, or an AI agent. Every payment carries an ID, and the CLI never resubmits one on its own. That sentence is the payment_idempotency value. The README does not say MCP, L402, receive-only permissions, numeric limits, fees, custody, or an llms.txt URL.

- last_verified: 2026-10-20
- notes: Library entry lightning-labs-agent-tools-launch (verified 2026-10-20) says seven composable open-source skills let agents run Lightning nodes, pay L402-gated APIs, host paid endpoints, and query nodes via MCP. It does not name an SPDX license, so license is null. Library entry lightning-agent-tools-l402-and-lnget (verified 2026-10-20) says the guide covers bounded per-request spending and does not publish a number, so limits is null. No llms.txt URL is stated.
