Part of [Lightning Enable](https://lightningenable.com) — infrastructure for agent commerce over Lightning.
Connect Lightning Enable MCP to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Part of Lightning Enable — infrastructure for agent commerce over Lightning. The lightning enable mcp mcp server is what makes that connection.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
pay_invoice — Freepay_l402_challenge — Freeaccess_l402_resource — Freetest_l402_payment — Freediscover_api — Freecreate_invoice — Freecheck_invoice_status — Freeget_balance — Freeexchange_currency — Freesend_onchain — Freeget_btc_price — Freeget_payment_history — FreeBecause this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
Configuration is passed through the environment: STRIKE_API_KEY, LND_REST_HOST, OPENNODE_API_KEY, LIGHTNING_ENABLE_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the payments and commerce options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Lightning Enable MCP's toolset — pay_invoice, pay_l402_challenge, access_l402_resource and 11 more — is a fair guide to whether it matches your workflow. It is maintained by refined-element; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
