About elisym
elisym is an MCP server published by the GitHub account elisymlabs. AI agent discovery, marketplace, messaging, and payments on Nostr - no platform, no middleman
It runs on your own machine: your AI client starts it from the npm package @elisym/mcp at version 0.34.1.
It asks for 2 secrets: ELISYM_NOSTR_SECRET and ELISYM_PASSPHRASE. Give it a key with the least access that still works.
Version 0.34.1 was published on 22 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 6 pass, 1 warn, 0 fail, 2 info. How we check.
