Quick Start
In case you get stuck, see troubleshooting section below.
Use the Alby-Hosted MCP Server
If your agent supports remote MCP servers - SSE (e.g. N8N) or HTTP Streamable transports, you can connect to Alby's MCP server.
- SSE:
https://mcp.getalby.com/sse - HTTP Streamable:
https://mcp.getalby.com/mcp
Authentication
Both require providing an NWC connection secret as authentication, either as Bearer authentication (preferred) or via the nwc query parameter.
Bearer Auth
Example: Authorization: Bearer nostr+walletconnect://...
If your agent UI supports bearer auth, just paste the connection secret into the bearer auth field.
